According to reports, NVIDIA has settled on the AD102-300 die for the RTX 4090, the company's next flagship desktop graphics card. Supposedly, the RTX 4090 will deliver 126 Streaming Multiprocessors (SMs), a few short of the AD102's die maximum offering. The RTX 4090 could only operate within a 450 W TGP though, contrary to earlier rumours.
