Frequently Asked Questions
- How much VRAM does Internlm2 5 7B Chat need?
Internlm2 5 7B Chat requires 14.6 GB of VRAM at BF16. Full 33K context adds up to 4.0 GB (18.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 7B × 16 bits ÷ 8 = 14 GB
KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 4.6 GB (at full 33K context)
VRAM usage by quantization
BF1614.6 GBBF16 + full context18.6 GB- Can I run Internlm2 5 7B Chat on a Mac?
Internlm2 5 7B Chat requires at least 14.6 GB at BF16, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run Internlm2 5 7B Chat locally?
Yes — Internlm2 5 7B Chat can run locally on consumer hardware. At BF16 quantization it needs 14.6 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Internlm2 5 7B Chat?
At BF16, Internlm2 5 7B Chat can reach ~200 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~45 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 MI300X → 5300 ÷ 14.6 × 0.55 = ~200 tok/s
Estimated speed at BF16 (14.6 GB)
~200 tok/s~45 tok/s~150 tok/s~124 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
