Old news. Philipp Slusallek has been pushing this for years. He had
an FPGA hardware raytracer that was doing 7M rays/sec on a 66 MHz
FPGA with 6M gates in 2005. Got a lot of pushback from nVidia and ATI
over this, which is a pity, but I just got mail from him that both
ATI and nVidia are adding RT acceleration to future GPUs... though
nothing as aggressive as his SaarCOR prototype.
An 8800 runs at, what, 400 MHZ and has 600M transistors. Given how
parallelizable raytracing is a dedicated raytracer with a similar
budget should blow past the magic billion rays a second without
difficulty... and be a lot cheaper and use less power than an 8 core
CPU.
