Hope they can replace the s**t GPU of Tegra 3.

How is it a horrible GPU? its the 2nd most powerful on the market right now.

It's probably(99% chance) better than the processor in his phone. Some people can't deal with hearing about new tech while still appreciating the stuff that's the high end right now. Those are the people who will never be happy.

I mean tegra may get to the market first when it comes to these things but they still hold their own throughout the year. I'll admit that the tegra3 mauls anything ive ever used, and ive had a 1.2ghz snapdragon, 1.8ghz OC'd exynos, and 1.3ghz OC'd tegra 2.

May I ask how the ULP GeForce of the Tegra 3 is the second best GPU in the market? I can name at least 4 better GPUs.
And I would agree that the GPU is one of the weak points of that SOC.
It´s good enough for the current tablets, but it will be short for tablets with full HD resolution.
In fact I would guess that is what the T3+ will be trying to improve.

I think that is the Achilles heel of NVidia's Tegra series. LTE is popping up all over the world & for your SoC to not take advantage of LTE is crazy to me. All the companies that are making LTE phones are bypassing the Tegra 3 chipset for Qualcomm's insanely well thought out Krait S4 line.
Also a dual-core 28nm 1.5GHz Krait S4 with Adreno 225 is giving the quad-core Tegra 3 a SEROIUS run in performance & battery life all with LTE on board. That is truly amazing in my opinion. Wait until the dual-core 28nm Krait S4 Pro with its 1.5 to 1.8GHz & Adreno 320 comes out (summer people) it will just destroy the whole NVidia quad-core line of Tegra 3's.
Now by very late Q4 or very EARLY Q1 of 2013 Qualcomm is releasing the quad-core 28nm Krait S4 @ a mind blowing 2.0 to 2.5GHz with the beastly Adreno 320. That will just be an insane piece of technology. The difference is the 28nm technology. It's just so much more efficient than NVidia's old 40nm technology.

This year i wouldn't consider Nvidia a major player like last year, it'll be between exynos and snapdragon until the new omap chip pops up, then we will see what happens with that, but yes you are right, nvidia is already getting mauled by a dual core with A15 28nm, you can only imagine the strength of the quad-core s4 with the adreno 320.
7. SuperAndroidEvo (Posts: 4791; Member since: 15 Apr 2011)
EXACTLY. Yes Sir.
Right now it's a S4/Exynos battle. I am interested to see how the new OMAP's will fit into the scheme of things! If the integrate LTE like they already do then they already win over NVidia.

The S4 doesn't have an A15 it hasn't even come out yet.
12. kshell1 (Posts: 1143; Member since: 05 Oct 2011)
You have no idea how much of an idiot that makes you sound. It has been confirmed that the one S, the evo 4g lte, and the one xL all use a Dual-core A15 28nm snapdragon s4. The proof is in the fact that one of these has already released.
14. remixfa (Posts: 14255; Member since: 19 Dec 2008)
for the love of god man... The KRAIT IS NOT AN A15.. ITS A A15 "EQUIVALENT " .. is it really that hard?
if it was really an a15 or its equivalent it would utterly smash the rest of the market .. but yet it doesn't. its basically tied for the lead with a 40nm A9 t3.. and just a hair above the 40nm 4210 exynos clocked at similar speeds.
if your going to be a fanboy at least be an honest one.
17. biophone (Posts: 1909; Member since: 15 Jun 2011)
You beat me too it and your explanation was better then mine too. I was simply stating a fact and I am apparently dumb because of that lol. Thanks remixfa.
21. SuperAndroidEvo (Posts: 4791; Member since: 15 Apr 2011)
remixfa Qualcomm's Krait S4's are built from ARM tech.
Here is a direct quote:
"Companies can also obtain an ARM architectural license for designing their own, different CPU cores using the ARM instruction set. Distinct ARM architecture implementations by licensees include AppliedMicro's X-Gene, Qualcomm's Snapdragon and Krait, DEC's StrongARM, Marvell (formerly Intel) XScale, and Nvidia's planned Project Denver."
So kshell1 in theory is right. Krait is ARM based. It might not be A-15 but it's built from ARM's tech. Who knows maybe it is built from a A-15. We don't know how much modification went in to it. We all know Qualcomm went 28nm first though.
27. GuiltyBystander (Posts: 199; Member since: 05 Mar 2012)
You can say that Krait is A9 on steroids.
16. biophone (Posts: 1909; Member since: 15 Jun 2011)
Qualcomm doesn't even use ARM they use Krait which is an equivalent to ARM but a worse version basically. So its not A15 its kraits. Its not as powerful as A15 because of its lackluster GPU so if you want to call it an equivalent to A15 thats wrong too its not as powerful. Whatever you want to call it the SGS3 is about to be released so who cares anyone. Its crapdragon its sucks.
24. SuperAndroidEvo (Posts: 4791; Member since: 15 Apr 2011)
You are wrong Qualcomm gets it's architectural license from ARM & uses ARM architectural implementations to make their Krait S4 chips.
kshell1 was partially right. He could even be totally correct. We just don’t know all of Qualcomm’s work on the Krait S4. At least the Krait architecture does come from ARM as per their license agreement!
29. GENARAL.LEVY (banned) (Posts: 93; Member since: 17 Apr 2012)
There are 3 versions of the A9 cortex......
31. TylerGrunter (Posts: 1503; Member since: 16 Feb 2012)
Sorry to correct you, but what you say it´s highly unaccurate.
Qualcomm does create his own chip architecture and don´t use the ARM one.
The only thing they license from ARM is the "instruction set" for compatibility.
You could consider the snapdragon family like A8 cortex heavily modified.
Don´t take it wrong, that doesn´t make any worse than the ARM ones as remixfa always suggests. It just means more competition and that they make their own architecture.
So kshell1 was flat wrong.

It isn't A15, but performance is almost comparable.
Oh, and it came out a year earlier, so there's that.
15. remixfa (Posts: 14255; Member since: 19 Dec 2008)
it doesn't compare at all to an A15
its biggest boost in power came from a die shrink to 28nm and a few pipe line changes. the first REAL A15 that has been benched, the 5250 runs at nearly double the horsepower of this "A15 equivalent ".. its marketing from qualcomm, not fact.
20. kshell1 (Posts: 1143; Member since: 05 Oct 2011)
Thank you for correcting me. meh im 15 im still learning lol
22. kshell1 (Posts: 1143; Member since: 05 Oct 2011)
And i wasn't being a fanboy, i was saying what i had read. Im by far any exynos person. I love my 1.8ghz OC'd exynos in my sgs2. It does anything another phone can do.
23. SuperAndroidEvo (Posts: 4791; Member since: 15 Apr 2011)
We don't know that it doesn't compare to a A-15 yet, because I have not seen a comparison of an A-15 vs. a Krait S4 yet. Plus the Qualcomm S4 Pro is still not out yet.
I really want to see the difference between a Qualcomm Krait S4 Pro dual-core vs. Samsung Exynos 5250 dual-core. I really don't think the difference will be as HUGE as your making it sound remixfa. I really think they are closer than you think & at those speeds the performance will be negligible at best.
25. Hunt3rj2 (Posts: 396; Member since: 11 Nov 2011)
It's been explained many times. Industry websites concur that Krait is close to Cortex A15.
28. Hunt3rj2 (Posts: 396; Member since: 11 Nov 2011)
The "biggest boost in power came from a die shrink" makes you sound ignorant, because Krait is clocked at 1.5 GHz, same clockrate as the Scorpions on 45nm. If I had a Snapdragon S3 at 1.5 GHz on 28nm, it would have.... exactly the same performance as the one on 45nm process. The only improvements to CPU performance thus far are purely as a result of having a wider pipeline and better efficiency in the CPU architecture.
I suspect by the time Exynos 5250 drops Qualcomm will have figured out how to extract high clockspeeds from Krait, much like how they went from 1 GHz to 1.5 GHz for Scorpion cores. I'd expect the next gen Kraits to easily clock up to 2 GHz or higher.
And if Exynos 5250 doesn't have big.LITTLE then it will definitely use more battery compared to Krait. It's a foregone conclusion that Cortex A15 uses more power than Krait clock for clock, because the CPU design is meant more for tablets and laptops than smartphones with 2 days of usage.
To sum things up: We haven't seen the full potential of Krait, Cortex A15 only gets more performance than Krait by using more power, wait and see.

Like 1% of the world has LTE access right now. While 99% of smartphone users would love enhanced performance. Of course, its better to have both, but if I had to choose between LTE and a better processor, Processor will win every time.
10. kshell1 (Posts: 1143; Member since: 05 Oct 2011)
The tegra3 isn't exactly winning anymore now that the s4 has released. The processing power of the s4 is higher, the only thing it falls behind in is the GPU slightly, can be fixed by rooting then OCing the gpu
11. biophone (Posts: 1909; Member since: 15 Jun 2011)
Snapdragon's biggest strength has been radio support but lets not forget the quad core exynos is around the corner. By the time snapdragon has gotten into the quad core game it will be too late. Exynos will be out. Not to mention by that time there will be a new omap and most likely the T4. Most likely relegating snapdragon to last. The S4 is ok for now but its not worth it considering what is going to be released very soon.
18. remixfa (Posts: 14255; Member since: 19 Dec 2008)
exactly. performance wise the s4 is already dead.. people just haven't realized it yet. for most people it will be a great chip .. but if your going by performance the s4 and the t3 are already ghosts.
19. biophone (Posts: 1909; Member since: 15 Jun 2011)
Heck if all your doing on your phone is checking emails or playing angry birds then the S4 is more then fine. Then again even the s3 or worse is just fine. Thats what most people do anyway. If you really want a powerful chip though its stupid to get s4 seeing whats around the corner. I don't know why people don't listen to you about chips clearly you are the most knowledgeable person about these chips. I learned a lot reading what you have to say. Hopefully other won't get so defensive about it.
26. SuperAndroidEvo (Posts: 4791; Member since: 15 Apr 2011)
Both you biophone & remixfa talk like you already know for sure. I don't know so how do you guys know?
I am willing to bet that the Qualcomm Krait S4 Pro dual-core will be so much closer in benchmarking to the Samsung Exynos 5250 dual-core than you guys say.
32. TylerGrunter (Posts: 1503; Member since: 16 Feb 2012)
I don´t agree with you here but for one thing: the chipsets Samsung will use this year are the 4212 and the 4412, both still with Mali-400 which is weaker than the Adreno 225 the S4 uses.
So why to dicuss with anyone about the 5250 when no one knows when it will be ready?
By that time Qualccomm will have the S5 series in the market, so you will have to compare with that.
And the S5 will be with Adreno 320 and clocked at 2.0 GHz!
