Can I Run Aya Expanse 32B on NVIDIA GeForce RTX 5090?
作者： Jakub Rusinowski · 最后更新： 2026年9月29日
Yes. Aya Expanse 32B needs 21.6 GB at 8K context (19.5 GB weights + 2.1 GB KV cache/overhead) at Q4_K_M and the NVIDIA GeForce RTX 5090 has 32 GB, leaving about 10.4 GB of headroom, at roughly 65 tok/s (estimated) with room for up to 64K of context.

Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 32 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the NVIDIA GeForce RTX 5090: 8K 21.6 GB · 32K 25.7 GB · 125K 41.3 GB ✗. Past 125K it no longer fits 32 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
