NVIDIA GeForce RTX 5090 To Debut With 2.9 GHz Base Clock

New information about the RTX 5090 graphics card has emerged from discussions on the Chiphell forums. A user named Panzerlied, who earlier disclosed that the RTX 5090 would feature a 448-bit memory bus, now reports that its base GPU frequency will exceed the RTX 4090’s by more than 600 MHz.

The leaker claims that the RTX 5090 will have a base clock speed of “almost 2.9 GHz,” which is significantly higher than the RTX 4090’s 2.23 GHz. This new base clock even exceeds the RTX 4090’s boost clock of 2.52 GHz. However, this does not necessarily mean that the boost clock will be much higher, as it is unclear if NVIDIA has altered how it manages clock speeds in the Blackwell-based gaming GPUs. Nonetheless, it is likely that the next-generation flagship model will feature a 3 GHz boost clock.

Rumors suggest that the RTX 5090 will be powered by the GB202 Blackwell GPU, although its exact configuration remains unknown. The complete chip is anticipated to have 192 Streaming Multiprocessors, translating to 24,000 cores if NVIDIA continues to use the same FP32 core count as in their previous Blackwell gaming GPUs. The card is also expected to feature 28GB of GDDR7 memory on a 448-bit memory bus. With a memory clock speed of 28 Gbps, this setup would provide over 1.5 TB/s of bandwidth, marking a 50% improvement over the RTX 4090.

All indications point to the RTX 5090 being a substantial upgrade over the RTX 4090, with more cores, increased memory, higher bandwidth, and significantly faster clock speeds. If NVIDIA can keep the launch price the same, it would be a significant development.
