NVIDIA's GeForce RTX 5090 GPU is rumored to feature a base clock near the 3 GHz mark which would be a massive uplift over the 4090.
The latest rumor comes from Chiphell Forum member, Panzerlied, who had previously shared info on the Blackwell "GeForce RTX 50" GPUs. While we still have no official word on the NVIDIA RTX 50 "Blackwell" GPUs besides Jensen Huang saying during a Computex Q&A session that the next-gen 50-series is "something" and that he can't wait to talk about it later.
So according to the newest rumor, it looks like the flagship NVIDIA GeForce RTX 5090 GPU will be an utter beast. It is stated that the base clock speed of the graphics card will be set at around 2.9 GHz, almost hitting the 3 GHz barrier. For comparison, the current flagship, the GeForce RTX 4090, has a base clock speed of 2235 MHz so that's a 30% improvement in the base clock alone.
There's no mention of the boost clock but knowing how previous GPUs worked, we can see it roaming above the 3 GHz clock with ease if the base clock mentioned here is true. The RTX 4090, despite having a boost clock of 2520 MHz (reference, would easily run around 2.8-2.9 GHz out of the box and some models even hit 3 GHz under the right thermal/power conditions. Well, that's about it as far as the rumor goes.
The NVIDIA GeForce RTX 5090 is expected to feature the Blackwell GB202 GPU. Although the full chip features a 192 SM and 512-bit design, the RTX 5090 is expected to be a slightly cut-down die with a 448-bit bus interface and 28 GB of GDDR7 memory. It will be really
