Intel talked about its Larrabee project and ray tracing at the GDC conference:
During a very interesting presentation by Daniel Pohl of Quake 4: Ray-Trace fame, The L-word (not the TV show Lost for those of you stuck in a cave for the past few years) was not just mentioned, but a slide was published for world to see.
As you can see now, Intel is using all of resources from the Folsom Prison, Houston bull-riding bar to a Biergarten in Braunschweig to get the chip done. Given the fact that description calls for “highly parallel, programmable architecture” that is targeting “Scientific Computing, Recognition Mining & Synthesis, Financial Analytics, Health applications and Graphics”, it is not a very hard thing to guess what Intel is working on - a cGPU, GPGPU chip that is set to start its life with a 12 mini-core setup, that will expand to 16 and 24 mini-cores in the future. We hope that putting huge-ass cache (4MB) in the chip is going to solve the branching issues that GPU chips have today.
Oh yeah, it is supposed to be a great chip for IntelRT, or simply - great for Ray-Tracing. If all things go as planned, silicon should be done by year's end, and the release date should be by the end of 2009, probably 2010. frame.
