Memory: RTX 5090 has 32 GB. Gemma 4 26B-A4B weights are about 15.4 GB at Q4_K_M (25.23B params × 4.89 bits ÷ 8, before context/KV cache). Arithmetic, not a measurement; long contexts need more. Check other quants in the VRAM calculator.

Speeds are decode (generation) tokens/sec as reported by each source; quant, engine and context differ, so small gaps are noise.
