Frequently Asked Questions

How much VRAM does MiniCPM5 1B SFT need?

MiniCPM5 1B SFT requires 1.0 GB of VRAM at Q4_K_M, or 1.4 GB at Q8_0. Full 131K context adds up to 2.4 GB (3.4 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 1.1B × 4.8 bits ÷ 8 = 0.6 GB

KV Cache + Overhead 0.4 GB (at 2K context + ~0.3 GB framework)

KV Cache + Overhead 2.8 GB (at full 131K context)

How fast is MiniCPM5 1B SFT?

At Q4_K_M, MiniCPM5 1B SFT can reach ~2944 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~662 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: AMD Instinct MI300X5300 ÷ 1.0 × 0.55 = ~2944 tok/s

Estimated speed at Q4_K_M (1.0 GB)

~2944 tok/s
~662 tok/s
~2201 tok/s
~1820 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
