Krait and Cortex A15

Anyone has thought about this?
ARM Cortex-A9 chip runs comfortably at over 3GHz

Wonder why they didn't do 3Ghz A15.

Because the A15 was never (AFAIK) put on the 40nm process - this was done for the sake of comparison between TSMC's 40nm and 28nm processes.

That's quite a bit of a speed boost there

Impressive. AMD better have some solid improvements planned in the Jaguar core or they are going to be left behind by ARM solutions (or adopt ARM solutions themselves).

Eh, my first question was what was the power draw, which they don't mention in the article. How do we know this isn't some "overclocking" publicity stunt?

[Bofast]

Power draw numbers would have been quite nice to see, yeah.

The HTC One XL/AT&T One X uses the MSM8960 chipset, the HTC One X uses the Nvidia AP33 Tegra3.

I think Laurent meant the radios -- T3 doesn't have them integrated, S4 does.

So the first benchmarks of the Exynos 4 in the Galaxy S3 came in, looks like they knock Snapdragon S4 and Tegra 3 flat.

The latest c't issue contained a CPU roundup incl. some ARM CPUs. They run CoreMark and SunSpider on many of them (CM compiled w/ GCC 4.7.0 on x86 (sounds like 32bit), and GCC 4.4.3 on Android -O3 -funroll-loops, -lrt, and using #cores * 2 threads w/o SMT and #cores * 4 threads w/ SMT).

Some results (CoreMark pts/SunSpider ms):
E-450 (18W): 6077 / 663
A6-3430MX (45W): 27645 / 423
A8-3500M (35W): 23903 / 472
Atom D2700 (10W): 4675 / 823
Core i7-2640M (35W): 48292 / 199
Core i7-3610QM (45W): 96358 / 196

OMAP4460 (2 x Cortex-A9, 1.2 GHz, 3W): 3268 / 1961
Tegra 3 (4 x Cortex-A9, 1.4 GHz, 2W): 3542 / 2276
MSM8260A (2 x Krait, 1.5 GHz, ?W): 4309 / 1838
