NVIDIA rumored to finalize GeForce RTX 5090, RTX 5080 design this month: RTX 5090D for China

NVIDIA's next-generation GeForce RTX 5090 and GeForce RTX 5080 graphics cards continue to get closer and closer, but designs of the RTX 5090 and RTX 5080 expected to be finalized this month.

In a new report, Benchlife chimes in on what is going on with NVIDIA's new Blackwell-based GeForce RTX 5090 and RTX 5080 graphics cards, with the RTX 5090 pegged at 550W power and the RTX 5080 at 350W power according to Benchlife, compared to the 600W and 400W power numbers from leaker kopite7kimi.

Benchlife reports: "This news is indeed a bit confusing. According to information from the module manufacturer, there was indeed a 400W NVIDIA cooling module case earlier, but it is currently in the cancellation or suspension stage. As for the 600W cooling module case, it has never stopped from the beginning until now".

"The module manufacturer also confirmed that NVIDIA currently has 5 GeForce RTX graphics card cases in progress. Perhaps 400W and 600W refer to the maximum cooling capacities of the radiators. In reality, the TGP (Total Graphics Power) of the GeForce RTX 5090 and GeForce RTX 5080 are 550W and 350W, respectively".

The site added: "if everything goes as planned, the Blackwell GPU architecture GeForce RTX 5090/D and GeForce RTX 5080/D are scheduled to finalize the design in September. If what our source told us is true, more information will soon be available online for reference".

• RTX 5090: 550W (new) 600W TDP (kopite7kimi rumor)
• RTX 5080: 350W (new) 400W TDP (kopite7kimi rumor)
• RTX 5070: 220W TDP
• RTX 5060: 170W TDP
• RTX 5050: 100W TDP

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.

GDDR7 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.

RT 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.
