1-bit Bonsai 27B on the NVIDIA GeForce RTX 3070: VRAM by quantization
| Quant | VRAM needed | Fits 8 GB? | Max context | Whole PC |
|---|---|---|---|---|
| 1-bit (binary, ~1.125 bpw) | 6.3 GB | ✓ Yes | 8K | — |
Assumes an 8K-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 8 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 1-bit (binary, ~1.125 bpw) on the NVIDIA GeForce RTX 3070: 8K 6.3 GB · 32K 11.6 GB ✗ · 128K 32.5 GB ✗. Past 32K it no longer fits 8 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? 1-bit Bonsai 27B on 16 GB of system RAM, CPU only: runs comfortably.
