New information allegedly about NVIDIA’s GeForce RTX 5090 and RTX 5080 GPUs have made their way online. Rumours of the GPUs’ supposed specs come from none other than the reliable and populat leakster, Kopite7kimi
According to their post on X, the RTX 5090 is reportedly set to use a GB202-300 GPU, and ship with 21,760 CUDA cores, which makes NVIDIA’s current king-of-the-hill, the RTX 4090, look weak by comparison. For context, the latter has a 16,384 CUDA cores. Other specs suggest that the GPU will have 32GB VRAM, 170SMs, and 512-bit memory bus.

In addition, and based on earlier rumours, the RTX 5090 could require two 12VHPWR connectors to run, because of its alleged 600W power draw, which again, is far more than the 450W that the RTX 4090 draws. One 12VHPWR is capable of churning out 600W, but if news of the PSUs are to believed, the presence of two connectors could mean that NVIDIA might be forcing users to not just buy a new PSU but also to split the power delivery between them.
RTX 5090 notwithstanding, the alleged specifications of the RTX 5080 point to a GB203-400 PCB, with 10,752 CUDA Cores, 16GB VRAM, 84SMs, and a 400W TGP. That’s a moderate increase in CUDA cores compared to both the RTX 4080 and 4080 Super, which have 9,728 and 10,240 cores, respectively.

And while it remains unconfirmed, earlier rumours have suggested that NVIDIA’s Blackwell-based RTX 50 Series will be the first cards to use GDDR7 and run with the new PCIE 5.0 interface. Of course, rumours being rumours, we have no choice but to take them with the general surgeon’s warning of sodium consumption, at least until NVIDIA’s anticipated announcement later this year.
