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 8 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
No compatible GPU? Gemma 2 9B IT on 16 GB of system RAM, CPU only: runs, but it is tight.
Why It Does Not Fit
Every Gemma 2 Family variant requires more VRAM than the NVIDIA GeForce RTX 3070 provides (8 GB).
Nearest GPU That Fits
