NVIDIA 28nm Wayne to have two versions?

Bright Side of News writes NVIDIA's 28nm Wayne may arrive in two versions. This Tegra chip is expected to arrive in 2012 and will target the smartphone, tablet, netbook and notebook markets. It seems one version will focus on smartphones, while a more powerful edition will target Windows 8 tablets, netbooks and ultra-low-power notebooks of up to 13.3" in screen size.

This first silicon is targeting the 1.5GHz clock for the ARM cores and packs triple-digit GFLOPS number. Given that the competition already announced 2GHz and 2.5GHz parts based on Cortex-A15 CPU core, we asked wouldn't 1.5GHz clock prove uncompetitive. The answer was that 1.5GHz is targeted for core-per-core comparison with the A9-equipped "Kal-El" T30 and that final clock speeds depend on the power consumption as the "Robin silicon" needs to keep the same power envelope as Kal-El.

Second Wayne silicon can be described as "Holy Smokes Batman". Unlike 4/24+ "Robin", NVIDIA's is planning an 8CPU/32-64GPU part for tablets, netbook and ultra-low-power notebooks. Think up to 13.3" in screen size. We were confused by the "up to 64" claim as NVIDIA's contemporary Fermi architecture is designed in 32 and 48-core blocks. However, in order to reach the power targets, engineers are working to be as flexible as possible. Whatever the final design ends up being it is a DX11+ compliant part, with full support for OpenGL 4.x and OpenCL 1.x. Also, an interesting note is that PhysX was explicitly mentioned in the "we have full support for PhysX now" sense. Draw your own conclusions on what that means.
