Computer RAM

Hello ..
Does anyone know what the difference between 1333MHz RAM and 1066MHz RAM is? what is best? and some who know about my Acer Aspire 4820 supports 1333 RAM, as these "Komputerbay 8GB (2x 4GB) DDR3 SODIMM (204 pin) 1333Mhz PC3 10600 8GB"
The Specifications on the RAM I have right now.
Memory Technology DDR3 SDRAM
Max. Memory Size 8 GB
RAM 4 GB
Memory Speed ​​1066 MHz
SO DIMM 204-pin
Configuration Features 2 x 2 GB
Ram 4 GB

Your Acer Aspire 4820 has Intel Core i7 620M or i5-450M Processor? if so, I doubt that it supports 1333 MHz.
Have a look here or here. Memory Types DDR3-800/1066
You can insert 1333MHz RAM card but it will down clock to 1066MHz.
Of course, more MHz = more speed but first CPU should support it.

Thank you.. But maybe I should have wrote more details about my PC.
It is a Model 4820-374G50Mnks and it only has a I3 Processor
Clock Speed ​​2.4 GHz
manufacturer Intel
Speed ​​2 to 2.9 Ghz
Type Core i3
Multi-Core 2 cores
Processornr. I3-370M
Still the same or?

Thanks for more details but 370M is also same in regards to RAM support. DDR3-800/1066 and upto 8GB. look here.

Thanks for your quick answers, it was really helpful

Glad I helped you.
If you go through Toms Hardware forums, you will find lots of helpful info's. Its the best forum out there. Notebook review is also great website when you buy a new laptops.
Thanks...
Best Regards

I'll take a look at it

Intel Chip

Hello everyone
I've been reading for a few days in this forum about the Motorola Razr i
I certainly found interesting articles but strangely I have found that very few refer to the Intel chip
just as I have been looking about the chip of "Motorola Razr i" and found a curious comment
"Medfield z2460 was meant to test the waters and is the reason why it was launched in india and not the US. Just a precursor to the medfield z2580. The z2580 and Clovertrail will be offered in dual core variants (not to mention quad core for clover trail) and will ditch the imagination technologies sgx 540 for an sgx 544 mp2 which runs 34 [email protected] mhz.
The sgx 540 gets 6.4 gfllops @400mhz . The adreno 225 runs at 24.5 [email protected] 400mhz and the tegra 3 (t30l or t33) gpu runs 13 [email protected] mhz. So being that 6.4gflops vs 24.5gflops is relative to 202% what do you think happens with 34 gflops vs 24.5 gflops? Plus the s4 is 103 mflops single threaded while medfield z2460 is 90 mflops single threaded on the cpu side. That's pretty close. Dual core comparison with sgx544 might actually be superior and at a higher process node (32nm vs 28nm), and that's with an in order instruction set vs ARM's out of order. I don't see how you get "x86 Atom has very slim chances when taking on Qualcomm’s ARM processors or any other new generation ARM mobile CPU from Samsung or Nvidia" with that info. Your talking a gpu and a core.
Come spring they go out of order, not to mention ditching 5 year old architecture for silvermont, 22nm process and inclusion of intel hd gpu with 40 to 80 gflops (depending on eu count) and you think there will be no competition? Even the apq8064 adreno 320 only has approx 40-45 gflops but that doesn't include the modem so higher tdp .
Maybe the exynos 5250 with mali [email protected] 68 gflops will be a threat given release schedule but still, nearly matching single threaded performance with the best chip on the market (and with 5 year old architecture), and beating every ARM chip to date in java script for a first try/test the waters offering? Swap a gpu and add a core and its game on. And adding new architecture, 22nm, out of order instruction and hd graphics and ARM might have a problem until 64 bit ARM v8."

My question is How true is this?
not publish the link to the site because I do not know if this is right in this forum.
I apologize for possible flaws in my English.

I'm having a super-smooth experience, so yeah, the hyper-threaded single-core chip is doing a very fine job compared to the ARM competitors.
But is it true that Intel will go out-of-order for their next architecture? Because the whole point behind Atom processors was to take advantage of Intel's advanced lithography and well tought architecture, then simplify it to make it consume much less energy (and go from out-of-order to in-order was one of those simplifications).

Well I always thought Intel smartphone chips were more powerful CPU wise but gpu wise its behind.
And christ you can quote all the figures you like but it doesn't mean it'll actually reach that. Its what the individual parts can achieve.
Put them into a phone and reduce the power consumption to an acceptable level = a lot less than quoted figures

[Leak] Early benchmark of future ARM chip...

Hi guys
One of my friends today just receive some unknown sample product (He's working on a labs)
+Snap 810 @2,2GHz (development board)
+Tegra K1 64bit Denver Dual Core @2,5 GHz
+Tegra K1 32 bit Quadcore
Benchmark result of Snap 810 vs everything (early beta kernel complied with GCC4.9 and benchmark in 64bit if available)
Single core Snap 810 vs [email protected] 2,5Ghz: increase 25% in single thread and 50% Multithread
+vs Tegra K1 64bit: 28% loss in single thread and 50% faster MultiThread
+vs Tegra K1 32bit: 12% faster in single thread and 34,5% faster in Multithread (2 thread vs 8 thread )
+vs Apple A7: 13,5% loss in singlethread and 86,5% faster in multithread (Same, 2 thread vs 8...)
+vs Apple A8: 20% loss in singlethread and 71% faster in multithread (same thing, 2 vs 8)
Also I have benchmark of Adreno 430(driver and chip still beta): faster than 30% vs Adreno 420, more than 90% faster than Apple A7 (PowerVR G6430) but loss 8-10% vs Tegra K1
Also more breaking news: Samsung Note 4 Exynos version is using Samsung CMC221 modem, Samsung have plan to use Intel XMM7260 with 22 band LTE cat 6 but drop it and using own-product with 7 band lte and cat 4
And Exynos version this time is more powerful than Snap
P/S: All thing I mentioned is confidental and NO PICTURE OF THEM (if they found out we leak them, we will get....)

A little noob question about GPU S advance

Sorry for this question, but I'm very confuse about gpu of I9070,some people said "s advance have single gpu" but on website official novathor u8500 said "multi core gpu process graphics 2d and 3d" So s advance have single or dual gpu ? Thanks http://developer.sonymobile.com/knowledge-base/technologies/novethor-u8500/

S Advance has a single core Mali 400 MP GPU. And as far as I know, the Galaxy S2 also has a Mali 400 MP GPU - but its dual core (instead of just one core). If you read about Mali-400 MP in ARM's website (link), this is what you'll see:
Scalable from 1 to 4 cores the Mali-400 MP enables a wide range of different use cases, from mobile user interfaces up to smartphones, tablets and DTVs, to be addressed with a single IP. One single driver stack for all multi-core configurations simplifies application porting, system integration and maintenance. Multicore scheduling and performance scaling is fully handled within the graphics system, with no special considerations required from the application developer

So this shows that different phones can use the same GPU but with different number of cores.
PS: Anyone is free to correct me if I'm wrong.

Thanks for answer. It's very stranger because my galaxy S advance runs n.o.v.a 3 smooth and fast (mali400), and I have one tablet based allwinner A13 (mali 400), sometimes I got hard lags ( yes I always optimize my mb ram).
