Not only does the VRAM jump up from 24GB to 32GB in the RTX 5090, but it gets a lot faster too with GDDR7 memory. You’re getting both more of it and a faster speed at 32 Gbps.

The GPU itself is a decent improvement over the RTX 4090, with more, faster memory, more cores, and a gorgeous chassis. But in terms of brute force rendering it's only incrementally faster in comparison with the performance bumps from Turing to Ampere to Ada.
