The Bay Trail platform gives tablets some three times the graphics performance of earlier Intel Clover Trail-based tablets, and here is another one of the reference design tablets running the Unreal Engine 3D graphics demo, Epic Citadel.
Bay Trail tablets' improved graphics performance comes from an Intel HD GPU, which supports DX11, Open GL 3.0, has four execution units, with eight threads per unit, and can increase its clock speed to 667MHz for limited periods of time.
Here you can see a Windows tablet outputting its display wirelessly to the flatscreen TV at 1080p via Bay Trail's built-in WiDi feature.
Intel also demoed the tablet decoding a 4K resolution movie and outputting it at 1080p to the screen.
Bay Trail's GPU supports full hardware acceleration of video decoding for popular codecs, including H.264, VC1, and MPEG-4/H.263.

While this tablet is an Intel reference design, Windows 8.1 tablets are expected to be released shortly by Acer, Asus, Dell, Lenovo, Nokia and Toshiba.
