nVidia is bringing in the big guns. They have hired Bill Dally as their Chief Scientist.
Dally is one of the Masterminds behind modern parallel computing and hold 50 patents personally. He has been responsible for many of the advances in modern technology including work on low-power high-speed I/O and interconnects.
He will be coming onboard at a time when Intel is pushing their own form of parallel graphics processor, Larrabee. This new GPU from Intel is a multi-core x86 processor (80+ Cores) that can handle the complex graphical calculations by running them in parallel. This new way of looking at the GPU could enable the use of real-time ray tracing for rendering graphics in games, and other applications.
Bill Dally will certainly add some needed ammunition in nVidia's on going war with Intel and AMD.
