***The Official Samsung Galaxy S III Thread***

[Nexus18]

a lot of performance is to be gained with Software optimisation.

Indeed!

EDIT: Even when browsing the net all 4 cores are used - windows 7 and a lot of programs use 4 cores.

Yup every program on my PC uses 4 cores, however, it doesn't make any real world difference compared to a top end dual core. A bit like all the people that say you need at least 2GB of VRAM at 1080P when you really don't need that much, 1GB is sufficient as has been shown by benchmarks in games. The games will use more VRAM if possible but there will be no differece in min., average or max FPS

Why are people playing GFX intensive games on mobiles anyway, buy a PC or Xbox or something. Phone games don't need be more powerful than Angry Birds

Yeah, it's not something I care about either really. Games like Angry Birds and Draw Something I can understand, but intensive 'proper' 3D games I could never get into on a touch screen.

The free 32GB card only applies to pay monthly deals when you pre-order, not sim free. I'm only interested in sim free handsets.

32GB card is only free on Pay Monthly:

As long as all the cores are used its all good IMO. Here on Android though - I don't think they are being used anywhere near as much as on Windows - in which case powerful dual cores are better.

However with Exynos fully power-gated design it's pretty much a win win situation as no battery power is wasted.

It's better to have than not - just for the visual candy.

I've never understood why someone would pay for an FPS game on a phone. I mean lol, seriously. If you're out and about then presumably you have things to do, so why not just play proper games at home on a big screen. About all I play on the phone is free crosswords and 'unblock me'.

So when is the release date? I'm not getting one but curious.

 

[kona786]

Generalisation much - 6 billion people in the world - there's going to be a lot of different scenarios.

I'd like to use my phone as a games console connected to a TV

Not to mention the fact that more cores usually equals slower speeds per core on introduction. For example my 3820 has 3.8GHz per core whereas the 6 core 3930K has 3.2GHz.

The 3930K can 'turbo' up to 3.8GHz with lightly threaded loads, just like your 3820. Tegra 3/Exynos do the same thing.

 

[mrk]

Meh, pre-ordered!

Came to £544 total for it in black/blue/grey/whatever it is in whatever lighting, 64GB SDXC class10, free official bumper case & screen protectors.

Now to sit back and wait, a game I absolutely loathe!

I also received the o2 recycle pack today to send off my S2 within 14 days but if I do that then I'll have a week or so of not having an Android and having to use a spare iPhone 4....can I handle that? I don't know

The 3820 can turbo up as well.

Are you disagreeing that when a new processor comes out it generally has a slower per-core speed?

 

[mrk]

Not always but generally they may be slower per core but they perform better than the chips they're replacing. And rightly so. Die sizes shrink, performance increases, power requirements go down.

Moore's law.

The SGSIII camera is definitely a step up over the SII. Comparing the pics - the SII looks like the picture is taken through a dirty window - hazey effect. The SIII's camera is a lot clearer/much better contrast in those comparison pics.

Not to mention the fact that more cores usually equals slower speeds per core on introduction. For example my 3820 has 3.8GHz per core whereas the 6 core 3930K has 3.2GHz.

Single threaded applications will then be slower under the multi-core processor.

Clock frequency is not the end all of CPU performance, IPC plays a huge part so a device can be clocked at a lower frequency and still outperform a higher clocked CPU if it completes more IPC. Multiple cores CPU can have a significant impact on performance depending on whether the application/OS supports multi-threading, the efficiency of the processor's branch predictor and also the number of steps in the processor pipeline.

The clock frequency of a processor for the case you're stating has nothing to do with the number of cores as it has to do with an artificial limitation placed on that particular CPU as Intel fills in the different price segment in their line-up. Overclocking the 3930K shows that it's more than capable of running at 3.8 GHz without any worries.

Single threaded applications will be slower under multi-core processors? How do you figure? That makes no sense. Again it all depends on the efficiency of said CPU architecture. A single threaded application will running faster on a modern multi-core CPU clocked at the same speed as a single core Pentium 4 as the modern CPUs have much higher IPC, more effecient memory controllers will lower latencies and more memory bandwidth.

Those shots are lush, the more time people are spending with the phone and the more they reveal the more I love it.

 

[Supercow]

I'm upgrading from the S1 to the S3, reckon I'm in for a treat

Dont they general preform better pre core aswell, Ghz doesnt really mean much I guess.

What I want to know is if the auto-focus has improved because I must admit it's shocking on the S2. I was trying to film myself using a PDA the other day and had to give up in the end because it just wouldn't focus properly (and I wasn't moving the handset)

 

[estebanrey]

GHz is the speed is works at, yes there are differences in architecture that also effects the performance; AMD chips traditionally had lower clock speeds than Intels because they were more efficient on each cycle but I was comparing the 3820 with the 3930K which are from the same 'family' and use the same architecture.

You'll find that with nearly all new processors which feature more cores than the last generation, each core by itself is less powerful than it's smaller cored brother.

Now if you have good multi-threaded applications the extra cores will make up and exceed the slightly slower per-core speed but older applications will not benefit and will be faster on the quicker, lower core chips.

 

[fornowagain]

To compare the GS3 vs HOX from the Gsmarena reviews. Obviously different light, time of year etc but the GS3 looks better imo.

 

[Intratech]

Erm, is that a retail HOX? I've seen better pictures taken with the HOX.
