Not really. People don't look for Linux support as the primary driver of purchases. Even in Linux, Intel does better than AMD : CPU performance is largely OS independent.

HSA, on the other hand, is a major selling point especially with consoles.

If it succeeds it will be like AMD64... changing computing (to 64 bit).

We don't even know the clock speed of these chips or IPC.

Indeed we know it is already known, Quad Core Temash APU 1ghz X86 CPU vs ARM Cortex A15 Quad Core 1.9ghz in short Tegra4 is easily beaten there is no doubt.When it comes to graphics performance, Temash APU will be significantly better than Tegra4. Generally Temash APU / SoC is much better Tablet chip, than Nvidia Tegra4 from whichever angle you look Windows or Linux. Confirmation for this fact we will not wait for a long time, and at the end Jaguar APU/SoC is not a old Bobcat APU the difference is very drastic. smile.gif

You did not show any proof for any of your claims.

Why are you so impatient everything has its time and place, for further news and some Temash APU benchmarks that will be at this event below. wink.gif

ARM A15 (Tegra 4) is not in the same league as these two cores. also here is the AMD ISSCC presentation.

http://www.scribd.com/doc/126362330/ISSCC2013-Final-v5-pdf

Its confirmed that Jaguar (Kabini) is on a TSMC 28nm high k process. AMD has gone even more aggressive on power saving. a lot of the info is very technical. maybe electrical engineers / chip design specialists would understand it thumb.gif

Mentioned Tegra 4 because Tegra 3 is in Surface RT so maybe MS have Nvidia bias, but if MS ditches Windows RT then I could see 22nm ARM vs Jaguar battle for design win on the next low end Surface(high end goes to Haswell ULV).

Silvermont will need to be much, and I mean, MUCH faster than current gen Atoms to beat Jaguar. Remember that Bobcat literally trounces the current gen ones.

Silvermont/Baytrail is 22nm full out of order Quad core running 2.1 Ghz with Ivy Bridge IGPU architecture up to 3X times faster than current gen PowerVR, current gen Clover trail is 32nm dual core with HT running 1.8Ghz. The performance & performance/power difference from Clovertrail will be sizeable and 28nm Temash/Jaguar will have sizeable competition from this new Atom.

Actually, we have an idea of how those. AMD had a presentation on Jaguar before the end of 2012. About 10% greater clocks than Bobcat so possibly up to 2GHz. And at least 15% greater IPC than Bobcat, so ideally a little better than K8.

Actually, that may not be the case; Cortex-A15 is a lot faster than you give it credit for. Here is a comparison of Samsung's Exynos 5 (1.7ghz A15 dual core) against several Atoms and an old mobile i3. With Tegra 4's increased clocks and doubled core count over the Exynos 5, I can see it competing reasonably well with Temash in CPU performance.

Bobcat APU CPU part is based on the AMD K8 architecture, Jaguar CPU is actually based on AMD's K10 architecture.Jaguar CPU has almost all CPU instructions as Trinity APU, or FX Piledriver and this is a very important difference because old Bobcat APU has none of these new CPU instructions.If you look at this picture one of the major differences, in new Jaguar's Core is "128bit FPU Datapath" with everything else highlighted in blue. smile.gif

15% claim from AMD presentation have yet to be proven. Usually AMD claims are based on best case scenario, and not average.
Even if it is true, I don't see how 15% increase over bocat would make 1GHz Temach better than A15 @1.9GHz

The jaguar clocked at 2GHz are obviously not for tablets, and have much higher TDP

So ?

It was running on low settings
http://www.pcper.com/news/Mobile/CES-2013-Video-AMD-Temash-Prototype-plays-DiRT-Showdown-1080p

Haswell on the other hand can run the same game at 1080p on high quality settings
http://www.anandtech.com/show/6600/intel-haswell-gt3e-gpu-performance-compared-to-nvidias-geforce-gt-650m

Anyway, how does that prove that it is faster than Tegra 4 when there is no side by side comparison between the two ? I fail to see your point.
