SoC joins the fold of ARM-based processors for Windows 8

Now that Microsoft's Windows 8 is officially out of the bag, we can also confirm that it will be running on ARM-based processors from Qualcomm, NVIDIA, Texas Instruments, and, of course, Intel. 

Qualcomm will be unleashing its next-generation, dual-core "Krait" MSM8960 processor on upcoming Windows 8 devices. The Krait boasts clock speeds of up to 2.5GHz and integrating both 3G and LTE onto a single piece of silicon, CNET reports. Windows 8 has also been demonstrated running on a single-core 1.2GHz Snapdragon.

Meanwhile, NVIDIA showed off a Windows 8 tablet running on the quad-core Kal-El processor. The Kal-El boasts four CPU cores and 12 GPU cores, with five times the performance of the Tegra 2 that's currently used in NVIDIA-powered Android tablets.

Not to be outdone, Texas Instruments unleashed its own ARM-based Windows 8 processor, the 1.8GHz OMAP4470. The SoC is powered by a pair of 1.0GHz ARM Cortex-A9 MPCore engines and two 266MHz ARM Cortex-M3 (multimedia duties). That's paired with a single-core PowerVR SGX544 GPU that supports DirectX, OpenGL ES 2.0, OpenVG 1.1, and OpenCL 1.1 (said to boost graphics performance by 2.5x). 

The OMAP4470 promises an 80 percent increase in web browsing performance and better power usage. The SoC was designed for tablets, netbooks and smartphones running Android, Linux, and Windows 8, and can support up to three HD displays at a resolution of QXGA (2048x1536). 

The 45nm OMAP4470 will begin sampling the second half of the year, with the first devices based on it to start hitting shelves in the first half of 2012.

Good job, MS?

It looks like MS is on the right path. A version of Windows that runs on ARM along with apps like Word. Remember MS, not just the OS but the Apps need to be modified to run on tablets.

I am a little worried Win 8 will still be too big to run well on an ARM CPU, MS does have a bed habit of writing bloated apps, but hopefully they will prove me wrong and Win8 will be agile.

I bet they have to drop backward compatibility almost completely. In order to run a thin OS you need to strip everything that isn't needed. I pretty sure that includes backward compatibility, at least for pre-Vista apps.

If MS holds to tradition, Win8 will be horrible. Every other release of their main OS has sucked ever since I can remember. Perhaps they had 2 winners in a row that I can't recall right now, but that has been the rule and not the exception. So I'm looking forward to Win IX or w/e they brand it.
