GPU + RAM / RTX 5090
32GB single-GPU lab
RTX 5090 32GB with 128GB DDR5 for a larger single-device memory allowance. This capacity pairing is a starting point, not a complete PC or a promise of model fit; verify exact variants, runtime support and used condition.

NVIDIA specifies 32GB on the RTX 5090. This gives a larger single-GPU memory budget than standard 24GB consumer cards, while remaining a different purchase decision from a 48GB workstation GPU.
Check current runtime and driver support for Blackwell. Context length, quantization and concurrent requests determine actual memory use. Capacity alone does not establish throughput.

Check compatibility before buying
Confirm the GPU is supported by your runtime and operating system. GPU memory and system RAM are separate pools. Check the exact memory kit against your platform: DDR4 and DDR5 differ, and registered RDIMMs are not a substitute for desktop UDIMMs. Used variants keep a separate asking-price history from new stock, with individual seller offers. RigScore evaluates tracked price, not inference speed or compatibility.
