TI Demos Windows RT UI Performance on OMAP 4470by Brian Klug on June 14, 2012 2:52 PM EST
Last week at Computex, TI showed Anand Windows RT running on one of their own reference tablets. While performance was good according to Anand, Microsoft has instructed partners to not show off anything but the start screen for Windows RT and not much more in the way of video. Today, at TI's Media day, I was given a video (in addition to shooting some of my own, which is the second one below) of Windows RT performance being demonstrated on one of Toshiba's upcoming Windows RT devices. This runs on an OMAP 4470 SoC (which consists of two ARM Cortex A9s and PowerVR SGX544MP1) at final clocks. I'm told that Windows RT will not utilize the 2D composition engine on OMAP 4470 at launch, but may at a later date.
The last I saw Windows RT running on OMAP 4 was on an OMAP4460 at MS Build, where the platform was emulating Direct3D 9_3. Today's implementation on OMAP4470 runs native Direct3D 9_3 on a PowerVR SGX544, and is obviously much, much smoother. There were a few capacitive touch calibration issues on the tablet I played with, but overall smoothness was impressive on the Start screen and browsing the AnandTech homepage. This is a definite positive departure from Microsoft's previous rules passed onto partners which forbade showing much beyond still photography of the home screen.
I've uploaded my own video of the demonstration as well, which was on TI's own OMAP4470 development tablet.
