If it has a 500 Watt TDP, I'm not interested. I didn't like RTX 4090' 450 W already, let alone 5090' 575W (same process node = energy efficiency, just linearly scaled up from 4090).
384-bit/32-bit per GDDR7 memory chip = 12 GDDR7 memory chips. Possible VRAM memory configs: 24 GB VRAM = 12 * 2 GB. 36 GB VRAM = 12 * 3 GB (3 GB GDDR7 memory densities are used in 5090 laptops, in some RTX PRO workstation cards and in recently announced 12 GB RTX 5070 laptops). 48 GB VRAM = 12 * 2 GB * 2 (memory chips on both sides of the PCB (aka clamshell VRAM design), like in workstation cards, like a RTX PRO 5000). 72 GB VRAM = 12 * 3 GB * 2 (clamshell VRAM design).
A dubious rumour claims Nvidia is working on a GeForce RTX 5090 SE with a cut-down GB202 die and 32 GB of GDDR7 memory on a 384-bit bus. While such a configuration is technically achievable, it would require an unusual mixed-density memory layout, making the alleged specifications difficult to slot into Nvidia's current lineu
