NVIDIA will be rolling out next-gen GDDR7 memory on its next-generation GeForce RTX 50 series GPUs, with the GeForce RTX 5090 Founders Edition graphics card reportedly featuring 16 GDDR7 memory modules in a denser design.

It seems NVIDIA is changing up the memory layout for its new GeForce RTX 5090 over the current-gen RTX 5090, with the GB202 "Blackwell" GPU inside, next-gen GDDR7 memory on a huge 512-bit memory bus. If that's true, it would explain why NVIDIA would need to use additional GDDR7 memory modules around the GPU.

NVIDIA's new GeForce RTX 5090 will use GDDR7 memory arranged in a denser configuration, with the layout shifting from 3-4-1-4 to 4-5-2-5 (clockwise), which allows the board to support up to 16 memory modules.

NVIDIA might not use all of these modules, but if NVIDIA uses them all -- and with 2GB GDDR7 memory modules -- we could expect 32GB of GDDR7 on the flagship GeForce RTX 5090.

GB203 details: NVIDIA's new GB203 "Blackwell" GPU is expected to feature a similar CUDA core count to the AD103 "Ada Lovelace" GPU inside of the RTX 4080, so we should have 96 SMs (Streaming Multiprocessors) and 12288 CUDA cores. We should have performance upgrades with the Blackwell GPU architecture, so expect 40-50% more performance over the AD103-based RTX 4080 and RTX 4080 SUPER.

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.
