Yes. Gemma 4 26B-A4B needs 15.7 GB at Q4_K_M and the NVIDIA GeForce RTX 3090 has 24 GB, leaving about 8.3 GB of headroom, at roughly 127 tok/s (estimated) with room for up to 16K of context.

The numbers

Gemma 4 26B-A4B on the NVIDIA GeForce RTX 3090: VRAM by quantization

Assumes a 4K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 24 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 3090: 8K 18.2 GB · 32K 23.3 GB · 128K 43.9 GB ✗. Past 128K it no longer fits 24 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.

No compatible GPU? Gemma 4 26B-A4B on 24 GB of system RAM, CPU only: runs, but it is tight.
