Interesting processor and graphics tech - pre-release

This thread resulted from a post migration from the pre-launch thread on specifications, speculations and rumors by popular demand.

You may find that you're rejoining the conversation mid-stream, but if you're looking for a good discussion on the Nexus processor and graphics tech with details, you've come to the right place.

:)

Actually, I PM'd a few participants if they'd be ok about making that into a separate thread as well.

The few I sampled agreed wholeheartedly, but by that time, the discussion was dying down (I was new to the thread then, yes, and everyone was keeping the other mods busy) and everyone was pumped about thread statistics so I let it slide.

As I mentioned in http://androidforums.com/nexus-prime/429660-nexus-screen-tech-pentile-dpi-samoled.html, it's best to build tech threads that will survive this pre-launch thread. Those will endure and help newcomers to the Nexus understand and discuss various tech nuances throughout the life of the phone.

I think we can let the sleeping dogs lie because the processor chats included not only wonderful tech but a lot of chit-chat on which would really be used.

In future, if and when we do spin off a processor thread, ok to freely PM me and request posts from here get to automagically transported to there. ;) :)

As is typical in the real world - tech tends to work the night shifts, so tech posts on the night shift.

Nothing wrong with multiple threads to reflect this - it's not like we didn't give you a whole forum for the phone, so - you know. :) ;) ;) :)

(Am I using enough smileys for you cats? I can't tell, each group is kinda different that way. :p)

PS - 55. I moved 55 since last night. To move more would've broken the 9k marker and I just didn't want the insurrection on my hands. :D

weird... i didn't receive any PM from you about processor/GPU/SoC-comments... though ~50% of CPU & GPU-posts are mine :D

edit: i still hope the GSM-NP comes with either the exynos 4212 or the OMAP 4470...

wanna know why?

Adreno 220 claims 80M triangles/s
Adreno 225 claims 125M triangles/s
Mali-400MP (in the Exynos 4210) claims over 120M triangles/s
SGX540 @384Mhz should get about 70M triangles/s
Click to expand...
so as the GPU of the exynos 4212 is 50% faster than the 4210's, it should claim over 180M triangles/s
the SGX544 (of the OMAP 4470) is said to have an 2.5x overall GPU performance, so it should claim ~175M triangles/s

Ps: you see that i'm the nr #01 in CPu/GPU-comments? :p

Nothing weird about it. I picked some people at random, thought I said that. Random doesn't mean stop and evaluate post count or quality.

For today's move, I consulted no one.

We value each and every one of our 700k + members, including you.

Please try to understand that I am trying to manage a lot of forums and more threads. All mods are.

you said i'd be someone special and you'd never forget me :(



'kidding, i was just kidding ;) (though i am in fact the nr #01 in GPU-post [CPU - im not sure])


edit: i'll use more smileys next time so that you'll recognize that ;)

I think it's a mistake to get overly concerned w/triangle counts. I'm no graphics expert, but there are other factors such as RAM bandwidth and fill rate (even driver quality!) that can also have a dominant effect on the speed of a GPU.

still the SGX540 is pretty old, so it won't be able to support the newest API's... [like DirectX or newer versions of OpenGL, OpenVG and OpenCL....]
 
So i'm a little behind in what's been going on in the nexus prime forum (crazy friday night) just wondering what the general consensus was on the speed. I know steven's source said s/he was using one that had a 1.5ghz in it, but do you think that was only for the test model, and the retail version will be underclocked to 1.2?

nope... i think the retail version will clock @ 1.5GHz, but maybe with the option to underclock it to 1.2GHz for better battery life.. [so maybe you'll be able to underclock in your phone settings without rooting your device...]

but still... nothing official, stevens source could be wrong... it could be 1.2GHz, it could be another SoC (not the OMAP 4460)...

i still think the Verizon-version gets the OMAP 4460 clocked at 1.5Ghz, and the world-GSM-version with the exynos 4212 (just like the Samsung Galaxy S2 LTE HD) ;)

We had a poster in the mega-thread who reported that TI confirmed that 4460 is in fact shipping at full 1.5GHz w/o any delays whatsoever. So if Nexus ships at 1.2GHz it isn't due to scarcity or buggyness.

An interesting thing about underclocking: The chips automatically do it themselves when there aren't enough threads to keep the cores busy. So a 1.5GHz chip probably isn't even running anywhere close to 1.5GHz very often except when playing a game or doing other hard work.

Not only that, but 4460 has a pair of hidden ultra-low power (and slow) shadow processors onboard that handle mundane tasks when demand is very low and the big bad A9's aren't needed. You might've heard about Kal-El's kinky fifth core, but these types of shadow cores are already in use in existing chips. It's neat technology, and the apps never even know when they're being switched back and forth.

uhm sry, but wasn't that the OMAP 4470?

the omap 4460 only has the 2 Cortex-A9-cores,while the omap 4470 has 2 cortex-a9-cores + 2 low-powered cortex-M3-cores...

edit: funny thing i just found out...

compare these 2 pictures of the OMAP 4460 and the 4470 architecture...

notice how the OMAP 4470 has no SIM-Card-support? :D

4430/4460/4470 all have the M3 cores. Been poking through the TI tech ref manuals. I can't claim to understand that much of it, but Chapter 7 is all about the dual-M3's.

are you sure that it has a qualcomm-soc?

Some Korean blogs rumored for SIILTEHD Exynos but were updated some days ago to Snapdragon. I'd say first 4212 in SGS III. Still keeping fingers crossed for EU version Nexus Prime with it tho ;).

but they also announced the exynos 5250 with Cortex-A-15 and Mali T604-GPU... this will be the SoC inside the Galaxy S3, the 'leaked' document which said 4212 @ 1.8Ghz was 100% fake ;)

so exynos 4212 is still not used... but as it's just a variant of the 4210, which is used in the Galaxy S2, i'd say that the 4212 will be used in a variant of the SGS2, so probably the SGS2 LTE HD...

and pls give me some sources that say that the SGS2 LTE HD will have a qualcomm-soc... :p


so i do (for the GSM-Nexus prime) ;)

edit: look, the SGS2 LTE HD is listed with the exynos 4212 :p source

Hold on I'll go change it to a rubber band for the processor and while I'm at it I'll add a brand new battery based on cow dung. It may smell really bad but it lasts forever (mainly because you don't even want to use the phone). :p

Here, I think it's a Korean mobile operator's blog. At the bottom originally had 4212 as CPU but was changed 2 days ago to

So here, briefly I'll guide you through the Galaxy S2 HD LTE specs
(CPU, etc. Check haejusin information has been corrected by the manufacturer.)

Size / Weight | 68.8 * 132.65 * 9.5mm (minimum dukkebu criteria), 140g
Display | 4.65 inch 720 * 1280
CPU | APQ8060
OS | Android 2.3

hm.. ok but nothing official :p

damn you samsung, why did you have to write '1.5GHz Dual-Core AP' instead of '1.5Ghz Qualcomm XXXXX' or '1.5GHz exynos XXXX' :mad:

edit: but anyways... i'll be happy if the EU-version of the Galaxy Nexus comes with the exynos 4212 :D
 
ferdasyn said:
Well it does say manufacturer corrected the information, not sure how much is lost in translation though.
Click to expand...

i don't think that samsung contacted them for reporting the issue in CPU-specification :D

and i can't find any official statement from samsung reporting that the SGS2 LTE HD comes with the Qualcomm-Soc ;)

i think they just corrected the CPU-manufacturer-information... translation mistake?
