Actually the Exynos 4412 scores are a tad(3-5%) higher at same clocks and Exynos 5 is about twice as fast at same clocks

The enhancements that were put in A9 r4 will definitely speed up larger tasks, so what they claim is possible.
Do any of the other semis have integrated LTE in the pipeline for their SoCs? It seems Samsung is still forced to rely on Qualcomm for their phones (Galaxy S4 will possibly use S600 for USA)
Disregarding the performance, integrated LTE will be a big advantage if Nvidia can undercut prices. It seems Tegra4i will be fairly cheap since the reference design could cost as low as 100 $

To > 30% perf/MHz vs Krait? Given all the other benchmarks I've seen so far I'm skeptical, unless Krait is just bombing SPECInt somehow (but the numbers don't really look that great). If this is the case I'd definitely like to see further analysis that goes beyond marketing whitewashing.. there are sub-test scores, let's start with that...
Intel claimed only 0.245 SPECInt/MHz for Cortex-A9 (@1GHz) but this was a few years ago so the compiler performance was way behind where it is now.. and I don't really trust Intel either.
Well if Qualcomm undersized some parts of its design it's possible. You'd be surprised (or not) by how much you can change a benchmark result by (un)properly sizing some buffer. BTW I see T4i 20% above not 30%.
I am certainly not claiming nVidia is right, I just say I think it's possible. I'd like to hear something from Qualcomm or from an independant party. The problem is that given the state of smartphone/tablet benchmarking I'm not sure we'll ever see SPEC results.
Yes, Intel
Qualcomm's Snapdragon S4 Pro and Snapdragon 600 SoC's do not have an integrated baseband modem. The Snapdragon 800 SoC does have an integrated baseband modem, but is not expected on the market until the second half of 2013, and as far as I know, the Snapdragon 800 SoC is positioned as a high end smartphone/tablet SoC.
Right, 20% above Snapdragon 800 which itself is expected to be ~10% above current Kraits, but that remains to be seen.
OlegSH is corroborating it at least and I don't have any reason to believe he's dishonest or doing something wrong.. it's still weird though :/
Exyonos 5250 getting 2x the perf/MHz as 4412 is also highly bizarre. I've never seen it do so comparatively well on anything else. Maybe the benchmark's highly bandwidth limited?
Mediatek, various Renesas chips and ST.
I was so annoyed at this Nvidia PR slide, stating that Snapdragon S800 will be creamed by both T4 and the newly announced A9 based T4i, that I went from lurking to being a member!

Ignoring the fact that the S800 figures are their estimates, something they only barely allude to, as they clearly won't have hard data, unless they are guilty of spying
"Solution A" is a dual-core Krait @ 1.5 GHz and scores 1517 /2 = 758.5 per core.This figure is earily close to one quoted by Nvidia under Snapdragon 800.
758.5 / 1500 = 0.506 per MHz
Even ignoring any architectural improvements that Qualcomm have stated for their new Krait 400 cores, a 2.3 GHz S800 should be scoring at least (0.506 x 2300) 1163.6 in SpecINT, virtually the same as the A15 Tegra 4 @ 1.9 GHz. If Qualcomm are true to their word, we could even see figures 15% ~ higher than my first prediction, which well beyond T4.
I have spent plenty of money at the altar of Nvidia, I don't mind fighting talk, but making up such spurious rubbish insults us all.

To further add credence to the above figures, ARM quotes a SpecINT of 420 for an A7 @ 1.2 GHz, that is a performance / clock of 420 / 1200 = 0.35, higher than the 0.33 that Nvidia 'quotes' for a Snapdragon 800. So a low power & in-order A7 is able to outgun a Krait 400 core on a clock for clock basis, I am not expert on the vagaries of SpecINT, but I'm sure Nvidia has taken data for a S4 Pro @ 1.5 GHz and left it at that.

Maybe I'm missing something, but I don't really see how one follows the other.
WTF were they thinking? This is sure as hell not going to fool OEMs, it's not going to fool enthusiasts either, and no one else will ever see this slide. How does this accomplish anything, apart from making them look like idiots?
It appears that NVIDIA considers the Snapdragon 800 SoC platform to be the closest competitor to it's Tegra 4i SoC platform, and in some ways they are correct due to both SoC's having integrated baseband modem, due to both SoC's having a CPU clock operating frequency up to 2.3 GHz, and due to both SoC's having commercial availability by end of 2013. NVIDIA even states that Tegra 4i "is significantly faster yet half the size of its nearest competitor"

Must be a response to the "we clean Tegra 4's clock" comments made earlier by Qualcomm...

Whilst I think tegra 4i is a very good product on first look...I dont thing for even one minute those slides are indicative to real world comparisons between the two chips.
Anandtech states krait 300 has a 15% higher IPC....krait 400 brings other improvements to IPC further....as well as the extra clock speed.
Also adreno 330 should trounce the 60 *super beastlord nuclear warhead cores* of the ulv geforce...(note nvidia marketing speak..well might as well be
As for tegra 4....for me cortex 15s @ 1.9ghz are far tok power hungry for a smartphone....just my opinion of course...maybe either krait/a9r4 would be the sweet spot.?
Saying middle of 2013 and towards the end of 2013 is somewhat vague and not in any way precise, but like I said, the expectation is that Snapdragon 800 and Tegra 4i will be available in the second half of 2013.

Wow, and you know all this just from intuition? We will have to wait for real world test results to know the answer to most of these questions.

Middle of 2013 indicates june/july. S600 had a Q2 release and will be available for purchase in 4 weeks
And if we go back to Anands report, it actually states: "In terms of time frame, NVIDIA expects the first Tegra 4i designs to begin shipping at the end of 2013, with most devices appearing in Q1 of 2014."
So i dont see how its anywhere near the same timeframe as S800. If anything its closer to the 2014 designs Qualcomm will show at CES
