Preliminary specifications of Nvidia's GeForce RTX 5080 and GeForce RTX 5090 graphics cards have been published by @kopite7kimi, a reputable hardware leaker who tends to have access to accurate information about Nvidia's upcoming products. If the specifications are correct, then Nvidia's forthcoming GeForce RTX 5090 will be a monster with a 600W total graphics power rating (TGP). Many of these specs line up with previous leaks, just with a bit more detail in some areas. You can see our Nvidia Blackwell RTX 50-series GPUs guide for more details.
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. That massive number of FP32 cores will consume enormous amount of power, up to 600W if the leak is accurate. The card will certainly rank among the best graphics cards when it's released, even if the final specifications end up being slightly less impressive. Just don't ask about pricing...
By contrast, Nvidia's GeForce RTX 5080 is said to be powered by the GB203 GPU and will feature 10,752 CUDA cores, which is roughly half of the range-topping offering. RTX 5080 graphics cards are now projected to come with 16GB of GDDR7 memory with a 256-bit interface, with a TGP rating of 400W. 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.
