Snapdragon Themral Throttling [Discussion]

http://arstechnica.com/gadgets/2015/04/in-depth-with-the-snapdragon-810s-heat-problems/
This articles above shows that you don't always get what you paid for when you buy the newest bleeding edge tech. It's about the the thermal throttling in the Snapdragon 800 series SoC's. The good ones the bad ones and it def hows a pattern of things being worse off during the beginning of a number in the in the "x" placement ----> 8x0.
Seems like big buyers are being experimented with a bit, tisk, tisk.
Now let's discuss

I would like to see this test redone with all SoCs undervolted as far as they will go.

I just want to add 2 things to this discussion:
1) Every mobile device will throttle at some point. This is the only way the SoC is able to manage its temperatures in a device that has zero active cooling. Either the user stops using the phone and it cools down or they continue using it and it will throttle.
2) It is the phone manufacturer's responsibility to design a phone and chassis that can support the thermal requirements of the SoC they have chosen for their device. If a phone over heats or the SoC is so throttled that it can never reach it's maximum clock speed (such as the Snapdragon 810 in the HTC M9) then the phone was designed poorly (based on the required specifications) and they should have chosen a lower power SoC.

I can't understand what manufacturers are looking for when they pack such CPUs in their flagship phones: the speed of a SD 801 is still cutting edge, and it has been the only chip capable of combining acceptable power consumption with top performance lately.
I'm a N5 owner, and really can't complain about speed, but that is just because CPU-intensive tasks, like rendering a webpage or opening an app, often last for just a few seconds, during which the phone doesn't heat up enough for thermal throttling to intervene. I rarely play games with my phone.
If Qualcomm focussed on reducing power consumption in the last couple of years, instead of searching for overly high performances, now we'd probably have phones with the SD 800's speed, but lasting two days, and with consistent performances during every kind of usage.

Damn it Qua!comm instead of jamming reference cores in to chips get cracking optimizing drivers to get more performance out of existing products. The Adreno driver overhead is embrassing.

The Exynos 7420 delivers better performance, better thermal management and better efficiency.

thermal throttle, whats that?? ive disabled thermal throttle on every nexus thats ever had it, since the n4 that's the n4, n5, and now n6. but the n6 is the best at not getting hot. as i cant get it over 82C ever.

The problem is and it applies to terrible battery life is thin phones. We just do not need skinny phones. It's like women. We have been brainwashed into thinking thin phones and thin women are both sexy. I dislike women with a toastrack ribcage and would love my nexus 5 to be twice as thick. No throttling and huge battery life...

Only because its on 14nm, if it would be built on 20nm it would throttle down just like the sd810. This isn't so much qualcomm's fault as it is arm's fault, the a53/a57 cores are simply too power hungry, the sd805 with a7/a15 cores barely gets throttled at 20nm.

your post conflicts by itself lol.
Also the 805 is a krait 400(or 500 can´t remember) architeture based on the a50 (the 800/801 are a15, and the 400 is based on the a7 with some variants based on the a9). Basicly the 805 runs a proprietary cpu architeture made after the a50 one, with the armv8 instruction set.
However the 810 runs the a51/53 instruction set, with no modifications, straight from ARM.and that´s something qualcomm didnt do for a long time,and as we can see the 810 WAS rushed to the market(the whole 64bit race)
Now for the thread, talking about the 800 series (since its what we have),it seems to have a good performance-heat ratio,however we feel it on our nexus due to poor thermal design, in the case of the n4/n5 the shield used to spread the heat don´t even touch the SOC lmao.
Talking qualcomm in general, i cant understand why they still have fails, having more than 15years of experience (10+ being with their own custom cores) i would expect them to not have these issues, but they still do.Also not going back much to the past, see the snap S4 gen 1 series(i.e the krait 200 variants, USA´S S3, Nexus 4 and such), they also have hw bugs(for instance, only the first core can go to fully deep sleep), thats something i would expect for a new player, not one with 15 years of experience(to make things even worse, qualcomm has been on the ARM market pretty much since the ARM arch/instruction set came out)
Also to OP, the 615,610,410,210 are all good socs, so the YXY pattern isn´t something here
However i must remember you guys, the one to blame here after all IS qualcomm, we dont have fully documentations and technical details or for most of you(including me) fully understanding of how a cpu is made / works but the a51 / 53 cores itself are fine, one player to see its the exynos 7220 on the s6, it runs a MALI gpu(which is from ARM,) and runs a53/51 architeture with a few modifications(not to the arch itself, but to the chip, make more thermal efficient, support samsung own branded chips, modems ,etc) and it runs better than the 810.
Also what made the 810 look worse is the drivers, adreno drivers sucks (sorry for the word, but this is more of a rant), my 4 year old MALI 400MP gpu haves about the same performance as my 2013´s adreno 330 (s3 exynos 4420 + mali 400mp vs nexus 5 snap 800 + adreno 330)

@opssemnik No way your mali 400MP is faster than an andreno 330

It really isnt in raw power or optmized games(gta sa and the newest NFS)but on the rest(even gta vice city) my s3 can keep up, and in fact due to better thermal design it can outstand the n5 after some time of playing

Nothing wrong with toned. But this craze of super thin is crazy. As for batteries if some one had come out with a replacement back with a huge battery inthat sloped to the camera that clipped in to replace the other I'd of been in heaven. My Nexus is in a heavy Spiegen case and I'm always amazed how skinny it is when I take it out to clean. I prefer it in the case. Feels better built

I really hope Samsung fixes this "issues".
It sucks. Hard.

What is the problems with the exynos processor this year?
You think software issue or harware issue?

Whats wrong with Exynos cpu. Well it is the tortoise and the hare.
Intel speed shift it is not.

Exynos 9810 seems to be another 5410: made to impress in synthetic benchmarks, and stop at nothing to achieve that.

I will take this review with a grain of salt....agreed most reviewers don't go so deep and basically review their devices after a week of daily usage....but still if the problems were so deep..it would have been reported.
Like i said in the comments there, i believe most of the deductions from that test will not impact your day to day life. Information is great, but one must know when you need a "summary" and when a "thesis"
I am still buying this beauty next month and i am sure i would be satisfied.

Ive heard reviewers say and show on video the exynos having better battery life and a faster processor. Who to believe? I returned my snapdragon for an exynos because my SD got such horrible battery life. Just got the exynos so we will see. At least it can have root.

Grain of salt? Did you even read the review?!
Sure, Exynos this year will still feel smooth, just like it did last year; but there is no denying to the fact that Samsung is still not up in its game when it comes to GPU efficiency. Samsung will still need to tune the scheduler on this Exynos (if not already tuned with March update). And unlike those most phone reviews out there, Anandtech folks actually go back and update their reviews after substantial changes that manufacture might have made (AT also reports those suggestions to OEMs when they review).
Anandtech is one of the few tech sites remaining that review hardware like how hardware should be reviewed.
Do not dismiss such hard work just for the sake of sounding edgy on the internet.

I had the s9 for 10 days, sold it because I got much worse battery life than on my nearly one year old s8 and there were nearly no improvements at all. I only noticed these 3:
1. fp reader, better placement and much more accurate.
2. Sound from speakers which i never use, much better.
3. dual-sim.
In the end i felt that selling the s8 for 400 dollars more than I would get for my s8 was definitely worth it. Very happy with that decision.

As i said , such reviews have no real benefit for me as a everyday consumer. There's nothing to say that the author hasn't done an excellent job...he has. Point is whether you need such deep analysis , when you are never going to be affected. My view is <1% will notice these things.
Secondly battery is a very subjective thing, it depends on user to user and companies generally take a month or two to fix their stuff after a new release.

So I've had the exynos s9 all day and I gotta say it's much better battery life than my snapdragon s9. Only problem is now LTE doesn't work. Ughhh.

Even with a Exynos cpu, it will has godly performance.

Yes it's in depth but not always how it really is.
Look at his benchmark charts and realize that SD835 is almost every benchmark faster than Exynos 8895 and 9810. Well, we all know it's not the case in real life.
Apple's A11 is fastest soc in every benchmark but in real world iPhone 8 is nowhere faster than Android flagships depending on sort of apps you use.
Never trust benchmarks only. User experience is more important.

Those are not benchmarks; those are to test specific aspects of a SOC.
SD835 does still beat Exynos 8895 and 9810 when it comes to GPU intensive tasks; that is to credit QComm's exceptionally mature Adreno architecture.
SD835 will continue to beat these 2 CPU's when it comes to performance per Watt due to that.
SD810 was a failure, SD820 managed to narrow the GAP with E8890, and SD835 more or less went head to head with E8895.
Sure, synthetic benchmarks still favoured Exynos year after year, but the reality has not been that clear due to Samsung's DVFS being a year late compared to QComm. Those things might not be relevant to how a device performs (due to difference in choice of system variables and tuning); but they are very much relevant to judging how those SOC were designed and implemented. That is what the point of those tests are (over AnandTech and for their usual style of reviewing stuff).
You can check speedtests on ytube for SD845 vs E9810 and decide for yourself (speed tests are usually dumb across different devices but you can make some relevance when it comes to same device with different chips).
One such example:

AnandTech has published a testing article here for those of you who have been following this discussion and/or interested in improvements that Samsung and/or developers can bring to Exynos S9/S9+ via kernel modifications.
Improving The Exynos 9810 Galaxy S9: Part 1
Interesting read.
TL/DR:
Today’s results are just meant as a quick preview of the Exynos S9’s behaviour when removing what I believed the most offending parts of Samsung’s mechanisms. The results are very promising as we are essentially getting real-world performance boosts while at the same time seeing efficiency improvements and battery life improvements.
There is still a lot to be done - I haven’t really touched the scheduler or DVFS scaling logic, but I’m confident that it’s possible to improve things further. It’s unlikely that we’ll end up matching the Snapdragon 845 variant in battery life, as there are efficiency curve considerations at lower performance points that simply cannot be changed through software. But closing the gap as much as possible seems to be an attainable short-term goal.

Now Samsung chimed in on the issue
https://www.androidcentral.com/samsung-addresses-battery-issues-exynos-powered-galaxy-s9

I'm extremely intrigued but also confused at the same level. I ordered a regular S9 Dual-SIM after reading reviews and reports that told me it was a great device and a nice upgrade from my S7 Edge. Then I cancelled my order because I read that a lot of people with the Exynos variant have battery related issues. Then I kept reading and noticed most of these reports where from devices just a couple hours or days old. The more recent reviews seem to show a different picture. While still a mixed bag, battery performance seems to be much less of an issue in more recent reports. For some it's even better than their previous devices. The reviews/reports who seem to praise the performance (battery) the most include almost exclusively people who compare it to the S6 (Edge), S7 (Edge). So, I placed my order again for a Coral Blue S9 Dual-SIM. Don't care for the Dual-SIM but somehow it's the only variant available in Germany. Whatever.
This is by no means an accurate analysis of the current or past situation. It's my experience. It's not representative in any form or function.

The upgrade will be very notable over s7 generation.
S7Edge gave me great battery (6-7hr SOT); S8 and S8+ gave me lower than that (4-5hr SOT). Now S9+ again gives me great battery (6-7hr SOT).
All of them have been Dual SIM models; and yes, I did change phone that often since I had a way to upgrading for a very small price difference.
S9+ upgrade wasn't as cheap for me, so I'll have to continue on this for a bit longer. It is an exynos S9+ from India; and performance has not been an issue so far for me.

I had the regular s7 before and upgraded to the exynos variant s9, and it is true that battery life during the first week or two is not adequate. Battery life has improved much and overall it's still a great device compared to other devices out there. Yes, I do wish the battery capacity is larger and Samsung do further optimizations to get battery life on par with the snapdragon variant it isn't the worse and I'm able to get a full day out of it. Honestly if you can wait, wait for the s10. The new 7nm chips and rumored higher battery capacity should make a killer device. But you can't go wrong with the s9 believe me. Other devices out there are flawed one way or another and the touchwiz experience is honestly approaching perfection, yes it was terrible years back but now it's way better than stock android in my opinion.
In the screenshot below, the power saving mode only has decreased 10% screen brightness only. No other altered settings.

This is what I'm talking about.
Battery tests, even in-depth semi-scientific analyses are all over the place and inconclusive. It is true that battery life is very user dependant but there should be a common theme all across the board. However, I don't see anything like that. I can't dealt with this for 2 years. I cancelled my order and will wait for a better deal on the S9+.

So , it seems , my reaction to the anandtech review was spot-on. S9 , irrespective of the cpu variants, is still a great device and we must not confuse ourselves with too much information where none is reqd.
God willing, I should be getting my hands on the s9 in early May.

iPhoneX vs Note9 benchmarks...iPhoneX wins?

https://www.tomsguide.com/us/galaxy-note-9-benchmarks,news-27773.html
I wonder about these tests although it's really comparing apples to oranges with different CPU and OS but some things can't lie, and the tests are designed to be platform independent.
I gotta say I'm slightly disappointed the snapdragon 845 performs poorer in comparison... And supposedly the Exynos version this year performs worse than the snapdragon, which is a first.

Ask me if I care??

Do you care?

nah lol

They specifically only showed the benchmarks where iPhone X beats the note. There are also many where it's the other way around and by a large margin. And anyways the note 8 still beats almost everything for everyday usage if you look at some of the real life speed test comparisons on Youtube, and also it's still the best at memory management.

Hey if you want subway surfers to launch in 2.453 seconds the I phone X is for you. If you can spare the extra 1.123 seconds the note9 does everything else better. ?
Sent from my HUAWEI CLT-L29 using XDA Labs

IPhone x is better only at the first test, when the benchmark test is run by 4 times in a row to mimick gaming, it is on of the worst devices and gets hot while the note only loses like 4-5% of performance, note 8 lost 10% or so. Don't know where I read it but someone tested it out

Benchmarks isn't the end all be all. Basically if you want a phone that scores high benchmarks then the iPhone is for you.

I'm going to use the Note 9 for the features that it has. For the customization that I can do it. The multitasking/multiple apps I can have open.
I have iDevices, you can do some multitasking, but ios doesn't compare to Android for my needs.

I will leave this here.

Speed tests are irrelevant now. Most phones these days, even budget android phones, are way faster than they have been ever before. You get what you are paying for and millisecond differences in App opening doesn't mean anything at all in real world usage. But functionality, features, and style on the other hand, is what sets Samsung phones apart from apple.

AnTuTu makes the iPhoneX look like a joke next to the Note9. Geek Bench is one of the ONLY ones that the iPhone X wins on.

Samsung really messed things up with the Exynos 9810 chipset. In an effort to match iPhone's Single Core speed they ended up with a processor that runs hot and abnormally high battery drain. Hopefully the new water-carbon cooling system will overcome these deficiencies. You're lucky to have ended up with the Snapdragon variant, it eclipses the Exynos and iPhone A11 in a majority of benchmark tests.

Only the uneducated will get their panties in a twist with these tests that are rather stupid. Yeah, you might be comparing one phone to another by using one score type, but how you get to the score is different for each phone. Almost ALL benchmark tests run different algorithms between iPhones and Androids. It is actually not possible to statistically compare them together. It sure makes for a great headline grabber though.
I always go bouncing between Apple and Samsung phones(mostly Note series). Not because I can't choose one over the other, but because I just like phones in general and I'm a tech geek.
These tests are stupid, because Apple said it themselves...it's not speed that makes a great phone, it's how you use it. And to me, the complete experience that Samsung has brought to me personally, in the form of the Note series, simply can't be matched by Apple right now! Geekbench scores can show an iPhone scoring 5 times as high as my Note 9, and I would still by my Note 9 because of my user experience.
People get so caught up with the useless numbers.

I used to own an iphone 8 plus. Mobile phones are built to be useful for life of a person. Okay, iphone a11 chip is a beast but what can you do EXCLUSIVELY, NOT AVAIBLE FOR OTHER ANDROID PHONES in iphone? NOTHING.
But i can do these on my NOTE 9:
1) Take notes easily, draw for fun without any lag and sharing is smooth. No crushes..
2) Access every every details of settings. I can easily disable GPS with one tap.
3) Google services are naturally more integrigated.
4) I can see all the details of my photos. I can shoot raw, i can shoot manually.
5) Thanks to edge screen, my favourite apps are one tap away.
6) Charging is way faster, charging cable and adapter is included.
7) AKG and ICONX earbuds came for free with Note 9 pre-sale.
8) VPN connection is faster. Doesnt drop. I can see diagnosis of inbound speed.
9) 128 gb + Samsung cloud (15gb) + Dropbox + Google Drive. Cloud services are all integrated.
10) 960 fps mode, ultra ultra slow.
11) Take selfies with the cool s-pen.
12) Translate words with the cool s-pen.
13) I know that SAMSUNG will not slow my phone without warning.
etc etc...
Believe me or not, i used both iphone and note 9, i feel EXACTLY NO DIFFERENT in terms of speed. They are both fast. Benchmarks are no important for me. I chose the free life with no worries. I am in love with Note 9.

Another reason is because Geekbench algorithm for iPhone uses Vulcan whereas it hasn't been updated for Android phones that use the Vulcan graphic processing.

Exynos vs Snapdragon Battery Advert

Just noticed how the battery is advertised on the american samsung site as: "All-Day Intelligent Battery to keep you going dawn to dusk"
On the UK site it's advertised as "Intelligent battery that keeps you in charge when it matters most"
I hope this isnt a repeat of the issues with the S9/Note 9.
Has anyone found any comparisons of the chipsets yet or have concerns?
Seen one promising battery drain test by MrWhosTheBoss but nothing else
Benchmarks seem to favor the snapdragon again (apart from the single core Mongoose performance, as before)

7nm vs 8nm. I'm under the impression that the smaller process is accompanied by efficiency gains, just saying. Andreif did various tests on the QRD 855, and it showed some promising results. I personally expect the S10+ (855) to break some records.

Agreed.
Smaller process AND A76 vs A75 ARM performance cores. Hope its not as severe a difference as it was on the S9 and they improve their scheduler and power managment..
paying flagship prices for a sub par processor is not something Im a fan of..bad enough having to wait so long for software updates

yeah i also looking forward to see a battery comparison between the cpus. also between the different models with their different screens and batteries

One Italian site reported some ugly battery drain when using dual SIM, that was obviously on Exynos. Haven't seen any other report on that specific scenario yet.

Andrei now has his first comparison review up on Anandtech and Gary has his speed test g comparison up on YouTube...neither bode well for the Exynos :/
Would post links but I'm not allowed as too new

here you go. watched gary explains. i was surprised how bad the exynos performed. but in the end there is no choice bootloader unlock=exynos no matter how bad it is.

If you check the comments, you can see something is not OK w/ this anandtech perform test, a guy tested on S9+ w/ earlier exynos, and he got better results on 9810 (vs 9820).

Yeah but the video from Gary.
Honestly I think I will see no real difference for my normal use. No gaming.
What i am interested in is the comparison in battery life. I would say SD would be better here.

Question S21Ultra exynos vs snapdragon! Any winners

The early reviews seem to be mixed. Has anyone managed to source two together to give a verdict what is the latest and greatest amongst the two in all aspects not just performance.

CPU seems similar, GPU better on the SD. Exynos won't be similar on GPU until it gets AMD GPU next year.

Once it gets the AMD GPU it will destroy the Snapdragon and possibly finally level up with the Apple. Maybe not CPU wise, but definitely on the GPU front against Apple.

Edit. Wrong thread. Apologies.

This man is not accurate because the test he ran only on one device by his own and he let another person to perform same test on that person's device then he compared both even though the one with Exynos 2100 was set to QHD and the one with SD888 was set to FHD only!! I mean this could impact the tests negatively!! The test conditions should be exactly the same!!

Listen to this guy, he is from HK and he've got the Snapdragon 888, in this video at 3:38 he mention that he don't understand how the american youtubers claims a 1.5 day battery life while his own experience in much less than that (almost half of that) .. so many youtubers unfortunately lies about the battery life and obviously this fool people who buys that device with Snapdragon 888, many of them put the phone only on Wi-Fi and not on cellular, it's not good and not nice when they claim something which is so badly incorrect. Note that BEN from the video below is using the phone with a SIM card, not with wi-fi only!
Review for SD888

So in all fairness, I did go back and look at the speed test video he did between the two and noticed a few things
Looks like different people kicking off the tests (based on the table they are on and skin colour).
SD is in aeroplane mode and Exynos is connected to cellular but no wifi/mobile data.
Resolutions are very slightly different, but both look like they are in FHD, but the SD has a slightly lower resolution as the navigation bar is different and makes the screen slightly smaller. QHD makes a minimal difference to battery life unless you're doing something GPU intensive.
In all fairness, I've seen mixed reviews of both chips, but no idea how people are setting up their phones (always do a clean install!!!). Have to wait and see how it performs when the phone arrives.

Have you gone for snapdragon or exynos. I am on the fence for buying either and can't decide. Not enough reliable info but if its anything like last year then I would rather import 888 into the UK.

I pre-ordered the Exynos, trade in deal for my s10+ was good and I was in the market for some earbuds anyway.
I won't send my current phone in until I'm happy, 28 days should be enough to determine if the Ultra is worth keeping or not. (although won't get much of a chance to test out and about!).
I have considered SDs in the past, just a bit concerned about replacing it via insurance if it gets damaged (have to take it to a Samsung store). Seems like this year the SD isn't worth the hassle unless you constantly play demanding games which I don't. I would wait for the AMD S22, but I'm too impatient/tech whore sooooo couldn't wait.
The problem for me is trying to avoid Chinese phones (for ethical reasons), doesn't leave much choice!

Thanks a lot of sparing me time to get the info again, obviously the differences are there and i get so sick of people claiming they are doing something huge while they just needs to get more publicity than giving the pure truth to everyone!!
For my opinion, i will not accept any of the videos to let me purchase or not the S21 Ultra, because they always run the phone in "lab" conditions, not real conditions that could affect the whole experience!

I was in the same seat of you, not sure to get the Exynos 2100 in Sweden or i go for SD888 from HK. I have today S20 Ultra Snapdragon model and very happy with its performance & battery life but not the camera with the auto-focus issues and also for the macro pictures. So i was looking at all tests, feedbacks, reviews, i am now more sure that Exynos 2100 is for me this time because of the battery life and also the good performance, i know the GPU is weaker but for my part, battery life is more important, so with SD888 and its bad battery life there is no reason to buy it, i don't play games with my phones so i will be fine with Exynos 2100!
BTW, the Exynos 2100 gives me what i need, from full support for 5G network as my carrier has kicked off here in Sweden unlike the SD888 which lacks the important Band 40 and 42! Also the SD888 lacks the eSIM functionality!

I have been watching Gary's videos as well. Its a close call this time and I don't play games on the phone. Leaning towards exynos due to warranty and not having to import plus buds and tag as freebies etc. Just conscious of what happened last year and the difference was huge. Also samsung is not selling mmwave snapdragon or exynos outside of the US which is mean as mmwave is only a year or two away from landing in Europe. Why not treat all of its customers equally! I think with the recent history snapdragon had a novelty factor to it but others are catching up. Let's hope snapdragon doesn't become intel of mobile world.

Yea it's not exactly like for like but can't imagine it makes loads of difference. I'm also more fussed about battery life, so will test it once I get it and see how it goes, battery life is just so dependent on personal usage, although I will say Phonebuff do a better job of testing, i.e. standby times and such, which gives a better idea of relative performance.
Andrei from Anandtech does really good reviews as well, but so in-depth that they don't usually release in time for pre-order

Yes, for sure you are getting 2 years warranty with Exynos 2100 in UK (i think) because we get that in Sweden too, additionally you are getting the pre booking freebies (Galaxy Buds Pro + Smart Tag), then you don't need to compare Exynos 2100 with the extremely bad Exynos 990 because the CPU is exactly the same as in SD888.
Regarding the MMwave, i don't care about it right now as it is not implemented yet in the networks here in Sweden, but i do have full 5G support for the rest of the bands which give me an advantage when the 4G is fully loaded.
I think Snapdragon will not be the intel of mobile world because Samsung is getting AMD help and involvement in the coming products, this will change the game!

This e sim is really important as you can add profiles without the need for physical sims. I had double checked this with HK version and it does not seem to be on the spec sheet. Yes band 40 will be gold once o2 pull their finger out in the UK for 5g. I think the decision is made for me that its going to be exynos for me plus also get samsung pay to work which is really handy for store cards. I'm using s9+ now and I don't know how uncomfortable the size of s21 ultra will be!

What would you consider a clean install? Can you import settings from your samsung profile? I generally don't transfer with the USB, but I download all my apps after the phone is booted up from the original install. Only after the phone boots up and finishes the setup do I get the apps from the play store.

I would start fresh, download apps manually, most have a cloud back up that they use themselves to restore once they are installed. From a settings perspective I'd do that all again fresh and let the system determine sleeping applications etc.
Basically avoid smart switch!
Tbh it's a good sort of audit process to work out which apps you have that you don't even use anymore

I don't think I was prepared for quite how big this phone is dwarfs my s10+ in size and weight
