Nvidia CEO "Not Afraid" of CPU-GPU Hybrids
J. Dzhugashvili writes "Is Nvidia worried about the advent of both CPUs with graphics processor cores and Larrabee, Intel's future discrete graphics processor? Judging by the tone adopted by Nvidia's CEO during a financial analyst conference yesterday, not quite. Huang believes CPU-GPU hybrids will be no different (and just as slow) as today's integrated graphics chipsets, and he thinks people will still pay for faster Nvidia GPUs. Regarding Larrabee, Huang says Nvidia is going to 'open a can of whoop-ass' on Intel, and that Intel's strategy of reinventing the wheel by ignoring years of graphics architecture R&D is fundamentally flawed. Nvidia also has some new hotness in the pipeline, such as its APX 2500 system-on-a-chip for handhelds and a new platform for VIA processors."
Ray vs raster. The reason we have so much tech in Raster is because processing was not sufficient to do ray. If it had been we'd have never started down the raster branch of development because it just doesn't work as well. The results are not as realistic with raster. Shadows don't look right. You can't do csg. You get edge effects. There are a thousand work-arounds for things like reflections of reflections, lens effects and audio reflections. Raster is a hack and when we have the CPU to do the real time ray tracing rendering raster composition will go away.
Raster was a way to make some fairly believable (if cartoonish) video games. They still require some deliberate suspension-of-disbelief. Only with raytracing do you get the surreal Live-or-memorex feeling of not being able to tell a rendered scene from a photo, except for the fact that the realistic scene depicts something that might be physically impossible.
Help stamp out iliturcy.
Once upon a time the floating point was done on a seperate chip. You could buy a cheaper "non-professional" machine that emulated the fpu in software and ran slower. You could also upgrade your machine by adding the fpu chip.
Such FPU's do not exist today.
I think Nvidia should be worried about this.
