Will NVIDIA's GeForce RTX 5090 Flagship Really Be A 600W GPU? Not So Fast
Either way, the general expectation is that the GeForce RTX 5090 is going to be a power-hungry beast. Previous rumors suggest it will wield 21,760 CUDA cores, which is 32.8% more than the GeForce RTX 4090 (16,384 CUDA cores) and 32GB of GDDR7 linked to a 512-bit bus for 1,792MB/s of memory bandwidth.
