Samsung Exynos 5250 - production starting in Q2 2012

[juicytuna]

Whatever it is, you get the sense that Nexus 4 and 10 leave a lot of performance at the table, especially when you compare with other similarly specced devices.

I mean look here at the CPU centric benchmarks:

The Nexus 4 trails the Xperia Z by a strangely huge amount considering they are both based on the S4 Pro.

My gues is somewhere in the middle...on one hand you have the usual gimped nexus devices..on the other you have nvidia sipping the kool aid....perhaps the galaxy scores do add up after all.

My question is what happened to the snapdragon s600 version..as the article I read on gsm arena states that gs4 will be exynos 5410... (octa) and that it will be a world phone..ie one version...so....

Probably just trolling for site hits like 99% of these sites. There are far too many benchmarks with a Snapdragon S600 to ignore

Most likely this will be like last year. USA will get Qualcomm, the rest will get Exynos with and without LTE

Aren't Samsung still fabbing SoCs for Apple, my question would be, do they currently have enough spare capacity to produce tens of millions of Exynos Octa chips to satisfy global demand?

Supposedly Apple will leave for TSMC late this year. But Samsungs production capacity might be part of the reason why they are using Qualcomm just like last year for SGS3

My understanding is that Samsung used Qualcomm for SGS3 only in the US and because of LTE not because of production capacity issues.

That came out wrong. I meant that they are using Qualcomm again like last year but the reasoning for it this year is that they wont be able to supply enough themselves

Given that S600 uses a seperate LTE modem just like Exynos LTE, i dont see LTE being the reason this year

They did sell a variant of the Exynos 4412 based GS3, with LTE in Europe (GT-i9305), but it was a few months after the launch of the regular GS3, so perhaps time to market was an issue.

Qualcomm didn't have a discrete LTE modem available at the time of the S3 release, only offered LTE through their MDM SoC.

Yea they no longer had to do the different SOCs LTE thing by the time Note2 came around.

I think im most excited about the big little uarch...as in whether the a7s work as well in shipping products as they have shown in demoes.

Perhaps some could explain to me why a whole bank of 4 a7s is more efficient than say something more like 1 a7 and quad eagles....something like a cross between nvidias prism, big little..and qualcomms independent clocking krait cores...

You need someone to explain to you why 4 A7s is better than one? Can you not think of a scenario where you benefit from multiple threads running where some or all of them don't need to be executed on a Cortex-A15? A large number of games out there will already fit this scenario, not to mention OS tasks (background or otherwise) and any user directed multitasking of otherwise low threaded software.

Power management is not only relevant when you have one thread doing almost nothing. I think nVidia is brainwashing some people with their literature.

Of course I can figure out the performance enhancements exophase. ..its the power consumption that I thinking of..and if your on about using the a7s for gaming also..tell me then what are the a15s supposed to do?? 4 a15s to load up web pages and race back to sleep?? Waste.

If you are going for efficiency ballance...isnt 8 threads over kill..even if only 4 will be utilised, maybe 4 a7s and one a15 high clocked would perhaps be very usefull for a mobile phone...the a15 starts apps and loads up web pages in quick time..then swaps over to the 4 a7s....

Other wise a more power hungry but more powerfull version would be what I suggested firstly. ..similar to nvidias prism..but with big little flexibility. ..1 a7 and 4 cortex a15s. ..

But 4 a7s AND 4 a15s does seem like over kill to me.
Just my opinion..if you can think of a scenario other wise let me know.

Edit: I suppose having the 4 a7s does offer a smoother experience when power saving... perhaps big little is more flexible than even what I presume..ie using what ever combination/type of cores at the kernels disposal...3 a7s and 1 a15..ect.

Why not? Waste of what?

Well power and die space.

From the die shots of Exynos Octa, it seems that 4 A7s don't take up any more space than the 5th A15 core in T4. So do think that most games will fit into the performance envelope of a 1.2 GHz A7?

 

[Turbotab]

Well power and die space.

Are A15s really needed for games, which are mostly GPU bound?

I don't know the requirements are, but the A7s are validated if any of its threads make more sense to run on A7 than an A15, not just all of them. What I do know is this:

1) Most games don't have the means to vary their per-frame CPU requirements.
2) Most games work okay on hardware with lower end CPUs (like iPhone 4S: 2x Cortex-A9 @ 800MHz) even if they also have relatively powerful GPUs (iPhone 4S again), which a 1.2GHz Cortex-A7 can match.
3) Consoles in particular have driven game development to utilize many more threads than they have in the past, and this trend will only continue.

 

[Nebuchadnezzar]

Yes exactly that. Rendering a web-page is much more demanding than the most demanding games out there.

If you are going for efficiency ballance...isnt 8 threads over kill..even if only 4 will be utilised, maybe 4 a7s and one a15 high clocked would perhaps be very usefull for a mobile phone...the a15 starts apps and loads up web pages in quick time..then swaps over to the 4 a7s....

You're completely ignoring the point of extending the DVFS curve towards the lower end of power consumption.

Other wise a more power hungry but more powerfull version would be what I suggested firstly. ..similar to nvidias prism..but with big little flexibility. ..1 a7 and 4 cortex a15s. ..

Prism is Nvidia's marketing word for lowering the backlight brightness....................... And Nvidia's 4+1 is the opposite of big.LITTLE in terms of flexibility. "Nvidia's 4+1 with big.LITTLE flexibility" makes a much sense as a motorcycle with the storage space of a flat-bed.

But 4 a7s AND 4 a15s does seem like over kill to me.

We've been discussing this over the last 8+ pages.

Edit: I suppose having the 4 a7s does offer a smoother experience when power saving... perhaps big little is more flexible than even what I presume..ie using what ever combination/type of cores at the kernels disposal...3 a7s and 1 a15..ect.

Again, this has been discussed already and we've had vast amount of official data on the matters. Presuming at this point is a waste of time, and again, you seem to like wasting time here in this forum section a lot...

It actually saves power.

Saving area matters less than saving power
