Deterministic VRAM fit · not a benchmark
Find a GPU for your AI model
Choose a model, quantization and context size. The calculator returns GPUs that can hold the estimated memory entirely in VRAM, then maps those chips to real product SKUs and Amazon listings. This does not rank speed.
Assumptions used
- Model
- Falcon 3 7B Instruct
- Quantization
- Q4
- Context
- 8K
- Required VRAM
- 6.4 GB
99 canonical GPUs fit entirely in VRAM under these assumptions.
Lowest-cost full-VRAM option
Sorted by lowest current Amazon price among GPUs that fit entirely in VRAM. This is not a performance ranking.
