[ThinkTank] JIT Optimization w/ Hummingbird Chipset

The possibilty of Android 2.2 speed improvements made us Vibrant owners salivate in anticipation for the JIT compiler but didnt see a significant increase in performance like it did with the nexus one. One thing that could eliminate lag in addition to lag fixes is optimization of JIT for our CPU hardware. We would like a proactive effort for developer to investigate for the above avg user. (Non-Developers) JIT Optimization = Higher Linpack MFLOPS

I think we're getting it in gingerbread =p

Im tired of hearing about linpack and quadrent scores already,they mean nothing.This is the fastest phone on the market right now period,if you dont like it trade it for a g2 or what have you like the rest of the idiots on craigslist.I personally have used every android phone available on tmo including the nexus1,g2,and mt4g.I xan tell you imho this phone is way faster and more responsive,and obviously the display and graphics are 2nd to none.complain about the lack of flash or ffc,but please dont complain about speed and performance,and as far as lag,try flashing a bionix rom after a clean stock odin,I've been using it since it came out and can tell you bionix final v2,and my current rom obsedion v5 run smooth as hell w/ no lagfix or oc kernal.So do yourself a favor,ignore linpack scores.

yes, basing everything off benchmarks is dumb. however, you can't ignore the fact that optimizing JIT for the hummingbird will net real world performance improvements.

thank you.....and plus i kno about the myth of high linpacks = better performance. i said "JIT optimization = High linpacks". High Linpack is a side affect of the performance increase. The nexus One performance has jumped exponentially from 2.1 to 2.2 because of the JIT optimization of the Snapdragon in theory, it should do the same for the vibrant as well. Everybody's phone reacts to sofware differently. think im lying, ask the ppl who had vibrants that couldnt OC like the rest like myself or ppl who cant have Voodoo. Trust me lil boy i aint nowhere a noob. Please take ur trollism to some1 else who dont kno wtf theyre talkin about. Actually G2 is the fastest phone on the Market FYI despite being clocked at @806MHz w/o root. If i really wanted to get another phone, i wouldnt be posting stuff like this or being an active poster in a Vibrant forum right? Right????? Checkmate....

This has been discussed before, certain Qualcomm chips are better optimizer for arithmetic calculations than the Hummingbird it. It means nothing in real world usage, where the Galaxy S variants still dominate (with a "lag" fix, of course)

Still, despite obvious advantages of Qualcom's CPU, the Hummingbird still can benefit from software optimizations of JIT to efficiently interface the hardware. Performance may not jump like it did w/ the N1, but it would help. Just like a car w/ 600 HP. A car w/ that amount of power is just useless unless it efficiently gets ALL that power to the tires right? same concept applies.

We are not getting it in gingerbread. The snapdragon have faster FPU performance due to a 128 bit SIMD FPU datapath compared to Cortex-A8's 64 bit implementation. Both FPUs process the same SIMD-style instructions, the snapdragon just happens to be able to do twice as much.

Couldn't disagree more. I've also used just about every Tmobile compatible android smartphone. I currently have a Vibrant and I wish I would have kept my N1. And I almost pulled the trigger on trading in this POS for a G2 but the financial loss was just too great. I've yet to try any Bionix based MOD that was worth a damn. Not a one. Admittedly I've quit trying but I can't imagine much has changed.
The only thing keeping me from throwing this phone in the ocean some days is Cyanogen's team is getting close. I'm running the beta on a Euro SGS I have. Hate it as much as the Vibrant but I'm hopeful CM can save this phone from a sledgehammer.

Please, stop embarrassing yourself. The Nexus One is and was a great phone, but the Vibrant is better in almost every way. Better hardware, bigger screen, better screen, faster, and more units sold.

Wonderful analogy. I however do not love my Vibrant. I love the hardware and screen but because Samsung pulls the strings, usually I want to drop kick the thing because of it's limitations, instability and overall suck of the Samsung ROM. And yes, pretty much all the mods to it on here. Though Axura is about the closest thing my phone actually likes.

What makes you even think the Galaxy S line is even going to see Gingerbread? This is Samsung we are talking about...

Htc fell off and google knows it,thats why the new nexus is made by samsung,htc may have pioneered android but there sound always sucked and right now samsung kinda controls the display game,nobody else can produce super amoled and there abou to release super amoled 2,admitidly samsung has a bad rep for not supporting current models(i.e. The whole behold 2 debacle.) And words can't describe how much I hate motorola,htc is still good but I wouldnt call them the android kings,I feel samsung has alot of potential to become the flagship brand for google.

Oh Ye of little faith.......... Get real I have had almost every phone on the market (I can afford to buy what I want when I want) and after so many this has come closet to what I've been looking for especially since the 2.2 roms are out. My Biggest complaint about people knocking the phone is they always blame the phone for their poor flashing skills. This phone rocks and it is flexible enough to allow gingerbread whenever it arrives. Try that with a DroidX or HD7......(you fill in the name)....BTW I have a FFC and talk over 3g on it using tango without lag. I just need to make it so I can video a call to a computer and I am golden.
Bottomline..........this is a great phone........that is why there are so many devs playing with it.

You, my friend, are not very smart. This thread needs to be closed or moved to general. Just as you would make an idiot of yourself trying to argue relativistic quantum mechanics with physicists, you are doing now.

This thread got interesting. As has already been said the Snapdragon benefits from JIT more because of its 128bit SIMD. While I am sure there is probably some room left to optimize JIT for the Hummingbird I wouldn't expect anything near the gain the N1 saw. I guess it is good or bad depending on how you look at it but the latest 2.2 ROMs floating around is as good as it gets regarding 2.2 and JIT. Don't expect much if any gain there.
But lets face it in the real world the phones perform about the same which leaves me to believe the benchmarks are that much more meaningless because they usually don't test things you actually use the phone for. Some of them would have you belive the N1 is twice as fast as the SGS and anyone with a grasp on reality just knows that isn't true. This also makes me curious when I read about people saying their phones are slow. It makes me wonder what they have done to them to slow them down because even on the stock ROM my phone was pretty snappy. And on Onyx 4.2 my phone is blazing fast with no lag fix or OC! Seriously this ROM is crazy smooth and fast and everything works.
Don't expect much from CM that you can't already get in the 2.2 ROMs floating around here. CM will still be RFS and they are using the same lag fix as everyone else here and really there isn't much of an advantage to their ROM as long as that is the case. Sure they will have features that you won't see in other ROMs here but overall I expect the CM ROMs will perform about the same as the SGS source based ROMs.
As I have already said I think this phone is fast but if there is any real speed gain to be had it will be accomplished by replacing RFS with something more efficient.

Low Quadrant Standard Test Score

Hi guys,
I've just run a Quad Standard test on my N1 running CM7 RC2 and am getting a score of 1199, which is lower than even the stock 2.2. I've tried with SetCPU ON & OFF, but got pretty much the same score?
A while back, I've flashed the RODS MIUI ROM & the WM Kernel (1152MHz) and ran the test only to get a score of 1192.
Wonder what could be wrong??

It's a synthetic benchmark and therefore meaningless. Does the phone run ok, does it feel like there's a problem?
The only thing Quadrant is good at measuring is how well a ROM is optimised for Quadrant

The phone runs absolutely fine. Its not like i have any issues with it, but just wanted to compare how it performs with different ROM's.

Best to break out the stopwatch and perform some real world tests. They're the only ones that matter

The only major difference i noticed after switching to MIUI from CM7 is that booting is super fast. Besides that, everything else felt pretty much the same.
OFF TOPIC
Does anyone know how to get rid of the power widget on the notification bar?

The option is in the CM settings which can be found in the usual settings

I noticed this too when i ran the benchmark, but simply dismissed it because its not the final version of the rom, and just a RC

I meant in the MIUI ROM.
Also wanted to know which kernel is the better among Pershoot and WM?
After using the phone with MIUI for a couple of hours now, figured out two issues.
1. When im getting a call, the trackball starts flashing and only after a good 2-3secs does the ringer go off.
2. And while playing music videos, the audio-video sync doesnt seem to be perfect. Its as if the phone is lagging a wee bit. Could this be cuz i only got around 40mb of free space on the device??

Quadrant scores, IMO, mean nothing. They give you a numerical value on the specs and capabilities thattthe phone can do under certain situations but they don't give you any real world numbers.
Yes the scores on my 2.3.3 N1 were "low" as. Well but how do you explain it being just as fast (no exaggeration here) as a stick Atrix? I had both and took the Atrix back.
The Atrix has amazing specs and its hardware is awesome, but as an overall feel I didn't like it, the whole experience didn't feel fluid to me.
All in all, quadrant scores are good for testing stock phones and comparing specs to each other, but you should by no means use that to judge the quality or value of a phone.
That would be like buying a car off of eBay by only comparing specs and stuff written on paper; you ddon't have a feel for the car.

I've seen at least two side by side comparisons between the Vivid and the Galaxy Skyrocket; and the Vivid definitely plays second fiddle to it, too.

roms play a big role in scores. htc roms are some of the most graphical. try on a less graphical rom like samsung is using and it will prolly be pretty close imo

Probably doesn't help that we're underclocked to 1.2 GHz stock. Once we have root and can overclock back up to 1.5 GHz+ results should be more respectible.

In every day usage yea doesn't really matter considering I played with the Samsung Skyrocket at the store and the UI Stuttered and this one runs quite smooth. Yea I can't wait for the custom kernels so we can actual get the Real Speed out of this CPU considering if I recall the Samsung is the same exact chip just clocked up to 1.5ghz so my guess is we should actually probably be able to get this phone slightly faster than 1.5ghz considering it is underclocked unless samsung out of the box OC'd the chip which would mean lot's of returns. Either way can't wait to see some optimized Sense and Custom kernels and see what this thing can really do. I also keep forgetting our pixel resolution is quite a bit better which most likely is effecting part of the scoring.

Why the hell would a manufacturer OC a chip? These chips are designed to run at 1.5 ever since qualcomm showed these chips, HTC decided to underclock these to 1.2ghz because of may be battery reasons.
This phone leaves a lot to be desired when it comes to smoothness, my dad has an evo 3d and for some reason that rom seems to run much smoother than this phone, it seems like this rom is lacking in that department. I am sure it is software given they are using exact same hardware. The phone is smooth but not as smooth as the evo 3d. I would root this thing in a heartbeat when root is available.

How does the device actually feel? Felt pretty smooth when I briefly played with it. I wish people would put less weight in benchmarks.

It is quite smooth actually. I have never actually noticed any slow downs at all as opposed to other people. Plus we more than likely once it is rooted will get the cpu OC past the actual Stock speed the processor is supposed to be so that should make things that much smoother. Granted at the expense of battery life but still if you UC when the screen is off you shouldn't feel it too badly unless you are Constantly on the phone in which case you would probably want to UC it when the screen is on too.

performance compared to S2

Hi all!
I've some antutu results... it seems that on 1600Mhz, Note is far behind (compared to S2) in the following values:
2D (126 ?!)
3D (598 ?!)
SD card read (8.9MB)
this is with AbyssNote 3.1 kernel and Criskelo V1, but I've similar results with stock and other ROMs too. Using Chainfire's 3D driver don't change the results.
Do you have any knowledge about these values and/or the reasons behind 'em?

and what about real world performance not a benchmark?
benchmarks are great for giving people something to brag about, but these are not real world tests, compare it side by side for speed when using the phone not a benchmark

Try to run 2 or 3 time benchmark. this a known issue to Mali as GPU will always lock to 160mhz from the higher 267mhz..
For sdcard read/write use some app that change the sd cache size to higher value to increase that.

Exactly. Everyone knows that the S2 is currently a little bit snappier than the Note with stock ROMs. But the S2 has been out so much longer, so it's hardly surprising.
In a few weeks' time, the Note will be snappier on Gingerbread, let alone ICS.
You could say that manufacturers should get ROMs in better working order before they release the phones, but that's just the way software is moving in general (test out software on paying customers).

Note is pretty fast but ain't as smooth my dead S2. It's remarkable that Exynos can handle a large amount of pixels without slowing down that much.

Remember the S2 has to power 800x480=384000 pixels. While the Note has to power 1280x800=1024000 pixels.
This is 2,666666 times more!

Benchmarks dont mean anything. my S2 can score twice higher but it performs worse.

[Q] Performance Issues

I purchased a new prepaid T-Mobile Note 4 from BestBuy few days ago. Today I have noticed that when I run benchmarks, I am getting very low scores. On Antutu, I am only getting around 26000, but sometimes I am getting the normal scores i.e, 46k. Even when running other benchmark applications, I noticed that I was getting only around half scores but sometimes I am getting normal scores.
I don't understand this strange behaviour. Is my phone defective ? Should I return it ?
P.S: I have not rooted this phone. I tried a factory reset, and there is no power saving mode turned on.

Does the phone feel slow? Is it heating up under normal use?
Sent from my SM-N910T using XDA Premium HD app

The phone is OK and gets heated up at times. Yesterday I played MC5 for about 15mins it was okay,but sometimes while running benchmarks it gets heated up

Can someone help me my phone feels absolutely normal but my benchmark scores are not that good.... Really?
Stop benchmarking phones I keep telling people that.. Not everyone phone will perform the same as long as it feels nice and snappy you should be all set

Some people have loaded hundreds of apps on to their phones, which can affect performance.
Do you have a lot of apps? How's your free space?
I wouldn't really rely on benchmarks as the sole indicator of performance. That being said, is the phone laggy? You said it performs "OK" but one person's idea of OK can be quite different than the next persons idea of it.
Also, where did you purchase the phone from? There's quite a few fake Note 4's floating around. If you purchased it through your carrier, go ahead and request a swap.

Do you have on power saver mode?

Best buy sells note4 for TMOBILE? Hmmmm by me they don't support any TMOBILE.

I know benchmarks are not an indication of performance, but atleast there should be some consistency, right ? Sometimes, I get normal scores similar to other Note 4 devices as expected. But sometime I get HALF the scores or much less than older devices, something which is not expected out of this device. So I doubt is there anything wrong my particular unit ?

Yes they are selling a prepaid No contract Note 4 locked to T-Mobile network. I got it for 699. Now it is out of stock though ! And yeah, it is indeed a bad ass PHONE !!

Majority of benchmarks put so much load on processor that after few minutes it heats up, overheat protection kicks in and slows down cpu. If you run few benchmarks one after each other then phone has no time to cool off. There is some roms available on xda which modifies how long you can run on full speed and higher temperature until cpu slows down.

A modified kernel is the only thing that will allow you to adjust thermal throttling. Hoever i do not recomend adjusting theses settings, this will damage your cpu. Thats what the thermal governor is for.

Oh, yeah. When I got my N4, the benchmarks sucked! Slower than my S3! Rooted, put on a custom ROM and it's all good. No heating, nothing. Even went back to Stock when the update came...and it was still good. Not sure, what was wrong...or what happened from Stock to Custom to Stock...

Haha yes. It's very strange though. So, I have finally decided to root and install a custom ROM. I only hope there is no heating.
And do I lose the possibility of updating to official Lollipop through Odin (not OTA's) when the offical 5.0.2 comes out ?
Thanks

Overheating should be reduced. Lollipop you will have to odin stock firmware or if you made a back up of stock rom with a stock kernel.

I'm not gonna go running out to get lollipop as soon as it comes out. I will wait to see what issues people are having first. Right now I'm pretty satisfied with kit kat.
