Real Hardware: the GPU has been implemented on an FPGA.
FPGA are very power hungry compared to ASIC, but real HW. As the Verilog can be complied to ASIC design instead it just now needs the IP and money sorted to have a user chip, a chip for a MoBo or card.
This is quite exciting. So anyone with a suitable FPGA dev kit and the knowledge to use such can test out and adapt this?
