And this is why analyst calls, while often dry, are a wealth of information. In their Q4 2008 post-results conference call, NVIDIA clarified its AGEIA plans.
Huang revealed that Nvidia's strategy is to take the PhysX engine and port it onto CUDA.
For those not in the know, CUDA stands for Compute Unified Device
Architecture, and it's a C-like application programming interface
Nvidia developed to let programmers write general-purpose applications
that can run on GPUs. All of Nvidia's existing GeForce 8 graphics
processors already support CUDA, and Huang confirmed that the cards
will be able to run PhysX.
Last, but not least, Huang said developers are "really excited" about
the PhysX-to-CUDA port. "Finally they're able to get a physics engine
accelerated into a very large population of gamers," he explained.
Huang was unwilling to get into a time frame for the release of the
first PhysX port. However, considering this will be purely a software
implementation and Nvidia now has Ageia engineers on its payroll, the
port may not take too long to complete.
When is always the big question, but we can probably all be patient while at the same time salivating. Or can we?
