Speed calculator estimate

GPU Count Model

Estimate = 0.76 × bandwidth ÷ GB read per token (Q4 file size, scaled by active/total parameters for MoE). Fit = file size + 1.5 GB headroom ≤ total VRAM. Multi-GPU: VRAM adds, speed uses one card's bandwidth (layer split). Short context only. How this works

Build that fits it: 24 GB: one used RTX 3090
Build that fits it: 32 GB: two Radeon RX 9070
Build that fits it: 48 GB: dual used RTX 3090
