Moore's Law Is Dead has leaked the specifications and performance of the Nvidia GeForce RTX 50 Super desktop GPU series. The lineup consists of the RTX 5080 Super, RTX 5070 Ti Super, the RTX 5070 Super, and the RTX 5060 Super. The new boards are expected to enjoy noticeable performance gains over their standard RTX 50 counterparts.

DLSS 5 says hello

The reason why NVIDIA would release a SUPER refresh this late ("Q4 2026 or Q1 2027") in the release cycle (RTX 60 series expected in 2027..), is maybe because DLSS 5 requires even more VRAM (as per recent showcase, where 2 5090 were used), than what DLSS 4.x already does (path-tracing, upscaling, all require additional VRAM (or compute)) and there's no free lunch (unless the GPU chip is made on a smaller node, then the power saving are forever, actually).

Since it's not explained: The +50 % increase in VRAM is achieved by changing from 2 GB per GDDR7 memory chip to 3 GB (3 GB chips are already being using in e.g. 5090 laptops, which use the same GB203 chip as a desktop 5070 Ti / 5080, which both have 16 GB VRAM (16/2*3=24)).
A GB203 has a 256-bit wide memory interface and uses 256-bit/32-bit per chip = 8 GDDR7 chips and 8 * 2 GB per chip = 16 GB VRAM, or 8 * 3 GB per chip = 24 GB VRAM.
