It's not for gamingWe still know little about Hopper. It's believed this architecture will be made on a 5nm node from TSMC. The GPU architecture will be quite different, it's rumored to get two dies with 288 streaming multiprocessors. That's 2.6x more than the Ampere-based NVIDIA A100. At least in theory, and if NVIDIA gets the scaling right, this could result in a performance uplift of a factor of three.
Hopper will compete with the Intel Xe-HP/C and AMD CDNA2 GPUs. The first product with Hopper may be the NVIDIA H100 datacenter card.
NVIDIA's roadmap for the gaming GPU market is still clouded in mystery. The Ampere-based RTX 30 series will likely get some sort of refresh before the firm introduced the new Ada Lovelace-based generation. It's unlikely that the latter will hit the market before Hopper.
