NVIDIA’s next-gen GeForce RTX 50 series “Blackwell” gaming GPUs have had their TDPs leaked by PSU maker Seasonic, with the monster ultra-enthusiast GeForce RTX 5090 expected to have a 500W TDP.

In the leak, Seasonic details the RTX 5090 with a 500W TDP, and the second-highest Blackwell GPU — the RTX 5080 — with a 350W TDP. We also have TDP details on the RTX 5070 with 220W, RTX 5060 with 170W TDP, and the RTX 5050 with a 100W TDP. These are preliminary TDP details, nothing final, just leaks… just so you know.
NVIDIA’s new ultra-enthusiast GeForce RTX 5090 with a 500W TDP means it has an 11% higher TDP than the current Ada Lovelace flagship, the RTX 4090, with its 450W TDP. We should expect the new GeForce RTX 5090 to boost even higher in overclocked and custom RTX 5090 form, past 500W.
NVIDIA has been reportedly working on next-gen cooling solutions and PCB designs for its flagship RTX 5090 and RTX 5080, especially in Founders Edition GPU form, in order to handle the raw power inside, and the power consumption itself (500W ain’t easy, folks).
- RTX 5090: 500W TDP (+50W compared to RTX 4090) = 11% increase
- RTX 5080: 350W TDP (+50W compared to RTX 4080) = 9.3% increase
- RTX 5070: 220W TDP (+50W compared to RTX 4070) = 10% increase
- RTX 5060: 170W TDP (+50W compared to RTX 4060 Ti) = 6.2% increase
- RTX 5050: 100W TDP (+50W compared to RTX 4060) = 13% increase
NVIDIA’s current-gen flagship GeForce RTX 4090 has a base GPU clock of 2235MHz, so if the RTX 5090 rolls out with a 2.9GHz+ base clock, we’re looking at a 30% improvement in base GPU clocks alone. Add on that NVIDIA will be using next-generation GDDR7 memory that Micron has teased will provide 30% gains in gaming in both rasterization and ray tracing, we’re in for quite the performance leap with the RTX 5090.
We’re expecting to see the next-gen GB202 “Blackwell” GPU inside of the flagship GeForce RTX 5090, with a huge 448-bit memory interface and 28GB of next-gen GDDR7 memory. If we compare this to the 384-bit memory bus and 24GB of GDDR6X memory on the RTX 4090, the excitement for the RTX 5090 is building rather quick.
4K 240FPS gaming shouldn’t be out of the question — not for all games, obviously — but the new RTX 5090 should carve through 4K 120FPS and 4K 240FPS like a super-hot knife through butter.
4GDDR7 details: Samsung has its next-gen GDDR7 memory ready for NVIDIA, with GDDR7 memory speeds of 28Gbps and 32Gbps. We could see the faster 32Gbps GDDR7 on the RTX 5090 and 28Gbps GDDR7 on the RTX 5080, and probably on the rest of the RTX 50 series GPU fleet.
4K performance: NVIDIA’s next-generation ultimate gaming GPU in the GeForce RTX 5090 should have 50-70% more performance across the board compared to the RTX 4090, especially at the higher-end 4K resolution. 4K 120FPS gaming should be an even easier achievement for the RTX 5090 than it is for the RTX 4090. We’ve got 4K 240FPS coming this year and in 2025, so the RTX 5090 will be the GPU of choice for 4K 240FPS gaming in the future.
4RT performance: This is where the biggest performance improvements of the next-gen Blackwell-based GeForce RTX 50 series GPUs will come: ray tracing. Expect some rather large 2-3x performance gains using RT, probably 4x or more in some cases with the RTX 5090 and RTX 5080 against their RTX 40 series counterparts. Throw new DLSS 4 on top, and you’ve got some wowzers RT performance.
DLSS 4: This is probably my personal favorite part of the excitement of next-gen GPUs from NVIDIA, AI-powered upscaling with a next-gen DLSS 4 that works only on the new Blackwell-based RTX 50 series GPUs. We should expect even higher image quality than offered by DLSS 3.x and new levels of performance with DLSS 4 enabled on a new RTX 5090 or RTX 5080 graphics card.
Power efficiency: NVIDIA’s current-gen GeForce RTX 4090 can use anywhere between 450W and 600W of power depending on the model and overclocking, but the new GeForce RTX 50 series GPUs will offer far more performance-per-watt of the leading RTX 4090 and RTX 4080 SUPER graphics cards. Another exciting part to see unravel in the near future.
