Leak claims RTX 5090 has 600W TGP, RTX 5080 hits 400W
The 5090 sounds a lot like a dual-chip version of the 5080.
Nvidia's GeForce RTX 5090 — the flagship Blackwell GPU for desktop PCs — is expected to be based on the GB202 graphics processor with 21,760 CUDA cores, mated with 32GB of GDDR7 memory using a 512-bit interface. With a decent bandwidth uplift enabled by GDDR7, the RTX 5080 should significantly outperform its predecessor in high resolutions and should be a potent graphics card. Such a design is hard to yield because of the large die size, which is why redundancies are usually present — the 4090's AD102 chip for example has a maximum of 144 Streaming Multiprocessors (SMs), but only 128 are enabled.
