Snapdragon 600 vs Snapdragon S4 Pro

Well our snapdragon s4 is now considered "old" which is a bummer! Had to happen at some point tho I suppose. So how does this new chip compare? Does anyone know what's been improved?

The S4 Pro and the Snapdragon 600 are basically the same chip. The model number is almost identical (APQ8064 vs APQ8064T; the Plus, Prime, and 800 all have very different model numbers), same fab process at 28 nm, same L0, L1, and L2 caches, same GPU. The difference is higher clock speed (max 1.7 vs max 1.9 GHz), and potentially a faster/bigger memory channel.
By no means does the S4 Pro instantly become antiquated. Between it and the 600, they're more similar than they are different. The 800 is a different story...

I didn't think there was a big difference either between the 2, however the HTC one with the S600 is getting like 12000 on quadrant compared to the 5000 we get?
How do u explain that? I guess it could just be that quadrant isn't really optimised for our phones and is not giving accurate results.

From anandtech:
[snapdragon 600] "This is quad core Krait 300 (as opposed to 200 in MSM8960 or APQ8064) which brings a 15 percent increase in IPC as well as higher clocks (from 1.5 to 1.7 GHz), for about 20–30 percent higher overall CPU performance"
20 - 30% So significant but not huge.

I read on snapdragon s4 pro and compare it with spec of snapdragon 600 "the only" difference i got is memory technology, s4pro uses 533MHz LPDDR2 and 600 uses LPDDR3
Edit: our phone not made for benchmark, i read somewhere on google+ someone wrote about it.
Btw nexus is always behind in terms of benchmarking, but if you compare the smoothness even galaxy nexus is still so smooth.
Here is the link https://plus.google.com/u/0/101093310520661581786/posts/Q1yVmqtubG9 its exynos4 saga by one of exynos cm maintainer, but he give a reason why our benchmark not as good as optimus G.

Why do people care so much about benchmark scores? Does it really matter? The only test that should matter is your eyeball.

Well because sometimes its a good way of comparing the performance of 2 phones - unfortunately not the case with a nexus I've just learned. Eyeball is very subjective, benchmarks are not (well they shouldn't be!).

lol @ benchmarks please welcome to technology soon as you bought the phone it was considered OLD !

But it is great to have both real smooth and high score benchmark
Sent from my Nexus 4 using xda premium

S4 Pro is still quick and i can see it being developed in devices for another 2+ years. i would safely assume low end tablets would also start using it when the price of these chips are reduced

Never cared about benchmarks, Even with the PCs I build. I over clock my pcs as much as possible for REAL WORLD usage and as long as they allow me to do everything I want and more and visually everything looks and feels fine and is stable, I'm good to go. Same applies with these phones. The nexus has top of the line internals and stock android allows this phone to be the way it was meant to. Now I have flashed asylum which is awesome, and I have used just about every kernel. I do notice differences in kernels “cough, matrix is the best, cough", but the differences are “seat of the pants" which is a curse in my opinion. Benchmarking stresses components, and at the price of these things why take a chance of shortening its life.

Benchmarks do tell a part of the story. You can't say that a phone that scores barely 1000 on benchmarks is as fast as a phone that scores 5000. The numbers might fluctuate a little but you get the idea. Nexus4 scores pretty good on optimised benchmarks like antutu but doesn't score good on benchmark apps that haven't been updated for two years like quadrant.

AW: Snapdragon 600 vs Snapdragon S4 Pro
So far I can see only devices with Android 4.1, or less, score pretty high with Krait cores. We havn't any other phone with 4.2 and snapdragon CPU to compare fairly.

The dual core S3 in my Xperia S doesn't feel any difference to the quad core S4 Pro in my Nexus 4 in every day use so i aint going to lose any sleep.

The number I heard thrown around was 40% faster on paper, or theoretically. Real world applications that may translate to less but still somewhat significant depending on your use case.
The kicker is it seems to still be the Adreno 320, is that higher clocked than the S4 Pro? If not it's pushing more pixels in the HTC One.

[Q] safe gpu and cpu voltages!?

Hello i have been searching but cant find the max safe voltages for the CPU or GPU thanks if you can link me or help

Every device is different, there is no voltage that is perfect for every device.

That is called Stock behavior.
What, you think that Nvidia/Google/Asus sat around in a meeting and said to each other,
"Hey, look, we really could run this thing at 200% of our current maximums without any risks at all, but let's not do that because this tablet market isn't very competitive and nobody will care if our performance is crappy compared to other devices. Let's decide to operate it at only one-half or one-third of it's safe capabilities - for no apparent reason whatsoever - just so we can."

Just let everything as it is on default bro

Dude there is a "/official nividia voltage chart for tegra 3 somewhere all Tue devas talk about one." Thanks for answering. Yeah they could actually look at the new tegra 3 game console it is at 2.3 GHz and also the one in nexus 7 is under clocked to 1.3 to conserve battery life as it is vey stable to 1.5/1.6 ghZ

There is no default for the gpu on m kernel. Over clocking while theoredicly killing your prossesor faster actually can add life to our tablets becuase they will be able to run more recent things when tegra 3 becomes obsolete and we get better games and a newer os in a few major updates. I benchmark in 3dmark a good 3xs stock when in the 600mhz GPU range and 1.7 prossesor clock so i know this will help us run recent stiff. Just wanted to know is there is a nvidia specific """"chart"""" of some kind or manufacturer's guide to safe voltages and clock speed as some dev said" the voltages are high although within nvidia limits" do you know the limits is what I'm asking...

Not saying this is the case specifically for the N7, but there are many corporations out there who would do this type of thing (*cough* intel *cough*).

The game console nvidia shield has an tegra 4i which is far more powerful and can be clocked very high, theres no tegra 3 game console.
Safe OC goes up to 1.5 GHz, but look at one x+ still stable @1.7 ghz and 520 mhz gpu.

All semi houses sell their parts in different speed bins, and a price premium is demanded for the high performance bins. So the OEM gets to decide what the performance range will be - constrained by the price target of their design. The fact that a 2.3Ghz Tegra3 speed bin exists does not mean that all parts have that capability.
In any event the "voltage table" you are looking for is published in the stock kernel source code.
The N7, priced @ $200 never was a premium product. A damn fine value for the money, though IMO.
Hard to believe in the planned obsolescence hypothesis (in this case), as it appears that Google is selling the N7 at a loss. Usually planned obsolescence occurs hand-in-hand with a profit motive.

Buy exynos handset version for UK

Hi, anyone bought a exynos version and using it in the UK, if so how much did it cost, where from and are there any hardware issues using it?
I already have an S3, the snapdragon version doesn't seem like a big enough upgrade to me, looking to get the exynos version .

S3 Geekbench 2 -- 1374
S4 I9505 Geekbench 2 -- 3160
How much of an upgrade do you need?

Fair point, however I dont see any point spend the same money on an inferior phone, if I'm going to shell out for a new phone might as well get the best version or not bother at all.

Both phones have advantages and disadvantages. Under ideal conditions the CPU speed of the Exynos will give you better performance, although not by much. As a tradeoff the GPU in the I9505 is better and has better OpenGL support.
For me the ease of development for AOKP and CM makes the I9505 the better option and I will use 4G eventually when it becomes more widely available in the UK.
It's a trade off though. Are you prepared to have less support for the phone as a result of importing it? And for a slight performance gain in certain circumstances that won't even be noticeable in real terms? If so then the Exynos model becomes an option but I'm just saying don't expect a big difference between it and the model you can buy today by walking into your local shop. In real life terms you won't see it.

Can Note 3 beat iphone 5s in chess benchmark?

See world record by new iphone 5s which clearly on top all android phones right now...:
http://talkchess.com/forum/viewtopic.php?topic_view=threads&p=534985&t=43212
To see if Note 3 is near it all need to do is install droidfish app, set threads to 4 (in settings). From starting position, press M->"Analysis Mode" for 20-30 seconds and check the nps number at the bottom. (pls specifiy if snapdragon or exynos) - For example - see attachment from my note 2...
(EXYNOS - Cortex - VERSION REQUIRED FOR TESTING.)

I'll be honest, I've never heard of this benchmark and I'm struggling to see what I'm looking at here. .. but I ran it because I was curious. Good or bad?

I don't have a Note 3 (damn you Handtec!) but I do have a Snapdragon 800 device (Galaxy S4 LTE-A). When running the benchmark for 20s the score ranged from 560k to 640k.
The Note 3 may perform better, but the S4 didn't hit thermals. It appears that ARM implementations (i.e. Cortex cores) perform better in this benchmark than Krait ones looking at the thread you link to.

You are right - it looks like Exynos will do better also on Note 3 - but i want formal test to approve it. (btw, S4 Exynos does 820knps...)

It's not only that benchmark comparisons are pretty much useless , this obscure one OP mentioned seems to be even more useless...
The only thing that is more useless than stuff like that, is mentioning iPhone on an Android forum and of course this thread itself...
It ought to be closed, really .....
.

I ran it and it's ranging from 500k-600k-640- then back to 500's nps, snapdragon model.
Not sure what it means though.

it is not useless as this is very demanding benchmark that pulls the juice out of the cpu....OK - we can ignore the iphone 5s since it is 64bits cpu which gives it real benefit in this kind of test...
But we need Note 3 Exynos result to complete the picture...

The benchmark does an infinite search using the engine. Useful to see how the processor and OS work together to accomplish this. This could also point to differences in design, not necessarily deficiencies.
If anything it will show how fast a chess AI using that engine on that hardware will process.
Real world application? Not so much.

its seems very useless benchmark

M8 honestly you have a bet or something for this; you will buy a iPhone 5s or a note 3 from this chess thing; all the development of new phones like the 2 you mention are end up been judged by a chess game; I am happy that Apple and Samsung programmers are not Japanese because they would do harakiri
Don't misunderstand me but you can judge things better in your hands after a bit of usage and you can have better opinion easier than to fell to the placebo of benchmarking .

I understand what you mean... But still benchmark is comparable tool to see which phone will perform better under heavy computation load which tests cpu caches, memory speed, etc - highly tested on chess benchmark on which i know exactly whats is tested compared to other benchmarks that tests so many things and sometimes the result does not mean too much...
It os not only chess - it implies also to other distributed computation workloads - maybe you think who cares for those workloads - but still it gives you insight of the power of the phone in case you will be interested to use it for those workloads.

They already stated that they won't do it
Before note 3 release they said they might, but with the release they said it would just burn up so it won't happen.
Now the only hope are for the developer, but like always, they don't have any source if exynos from Samsung so I wouldn't get your hope up

No. but for a realistic multiprocessing soc, check out mediateks newest offering.
While its homogeneous multiprocessing, It still provides similar performance to half the number of A15's.
IMO Heterogeneous multiprocessing is a ways off since its still nary impossible on real (desktop) processors.

Samsung never sad it.. link me an OFFIACIAL news about it
There was an unofficial rumor wrote by an unknow person witch sad it, without any direct confermation
But, stupid's mom is always pregnant
Amyway.. until a software release (kernel module witch turn on the HMP feature) we only could have the cluster migration solution
Or 4 cortexA7 ore 4 cortexA15
Oh, power, understand me, 4 cortexA15 has an higher battery drain than 4 A7 + 2 A15
So, this actual condiction has an higher overheating issue
The only situation witch has a worst case is when all 8 cores are turned on
Wanna an example?
Playing with angry birds..
With cluster migration ALL cortexA15 are turned on..
With hmp, 4 cortexA7 are turned on and sometimes 1 or 2 cortexA15.. i repeat.. SOMETIMES
and it's a game
Do you thunk hmp has a worst batteryconsuption?
---------- Post added at 03:10 PM ---------- Previous post was at 02:55 PM ----------
http://forum.xda-developers.com/showthread.php?t=2556264
Look at this..
The ACTUAL way is this:
CortexA7 for background, and, when you touch the screen, cortexA15
Powergating works "bad" with this logic
With hmp, all cortexA7 at the base and cortexA15 added only when there is necessity
So.. it's a stupid thing to say hmp has overheating issues..
Only an ignorant say it since it doesen't knows how it works
Yep, 8 cores are more than 4 cores.. so.. more heating issue since 8 > 4.. 8 = 4 x 2 so hmp has double temperature heating..
Right? Logic..
if samung wont release hmp for note3, it will be only a commercial way to release hmp for s5..
Only a COMMERCIAL way..
I hope not
