To be fair, Krait will ship nearly a year after Tegra 3 started to. Other SoC makers could say in a year they'll be that far ahead of Krait too. But I am excited for Krait phones, that's quite an improvement.
I think some of T3s problems must come from its memory controller, they have four active cores and a GPU on a single channel controller while most dual cores are on dual channel.
We've yet to see any Tegra 3 phones on the market and phones with Krait-based SoCs, though not the 'Pro' version obviously, stand poised to ship at roughly the same time.
We might not see Cortex A15-based designs like OMAP 5 for some time yet but Krait seems ready enough if you follow the news.
Certainly, it won't ship a year after Tegra 3 as that would imply Q2 2013.
No, but still, by then Nvidia will probably launch the Tegra 3+, which should also be on 28nm.
I'd agree that CPU-wise, the Krait is a better choice today, GPU-wise I still think Tegra beats it.
But while we're arguing over which one is or will be more powerful between these 2, I think Exynos 5250 based on Cortex A15 will beat both of them in CPU and GPU performance.
Umm, the only benchmarks out there for the Krait come from Qualcom. I wouldn't jump to the conclusion that they are accurate until we have a third party confirmation.
I blame nVidia's "design-for-marketing". There is zero to no reason to waste die area for a phone device with quadcore. That area could've been better used either to make the chip cheaper, use towards lower-power cores (which nVidia did get right) or more GPU pipelines.
Now, on a tablet or a Windows 8 laptop running ARM, quad-core may make more sense and hopefully, these manufacturers will stick with putting quad-cores in those and having dual-core variants for smartphones.
So, you're saying that since current mobile phone software doesn't scale to four threads very well, hardware makers shouldn't attempt to progress their technology?
He didn't say stop making 4-core chips. He is just saying that tablet/laptop are used for more computationally demanding tasks, so it makes sense to have 4-core tablet; phones only need 2 cores.
he never implied not progressing their technology... he said that it was progressing in the wrong direction for "lower power" devices.
"That area could've been better used either to make the chip cheaper, use towards lower-power cores (which nVidia did get right) or more GPU pipelines"
i agree with him that this is where progress should have been made. and yes, making chips cheaper is progress as well, because OEMs can invest more in other aspects of the phone while maintain relatively comparable cost == better phones and better technology.
while i regret this year isn't big.Little's year, i'm hoping samsung's chips are better "progressed"...

Most interesting chipset of the moment. Tegra 3 looks like a bloated beast in comparison.tipoo - Monday, February 27, 2012 - link

Whoops, I meant all devices, not just phones. Yeah, Krait will crush T3 in phones.Lucian Armasu - Tuesday, February 28, 2012 - link

Which is why Samsung and Qualcomm have announced 'bloated' Quad-core SoC's? *facepalm*Arnulf - Monday, February 27, 2012 - link
If quad core Krait scales up proportionally it will hardly be bloated. Dual core version trashes Tegra3 so quad Krait should be even better.This actually looks like the first real challenger that could brawl with Brazos/Atom for dominance of the netbook segment.

Umm you must not have seen the benchmarks that Anandtech put up last week?metafor - Monday, February 27, 2012 - link

I could see the s3 getting this on att. Considering every devise on att that has lte is a qualcom chip
