Frequently Asked Questions
- How much VRAM does DeepSeek v2 need?
DeepSeek v2 requires 144.3 GB of VRAM at Q4_K_M, or 474.3 GB at BF16. Full 164K context adds up to 198.8 GB (343.1 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 235.7B × 4.8 bits ÷ 8 = 141.4 GB
KV Cache + Overhead ≈ 2.9 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 201.7 GB (at full 164K context)
VRAM usage by quantization
Q4_K_M144.3 GBQ4_K_M + full context343.1 GB- Can NVIDIA GeForce RTX 5090 run DeepSeek v2?
No — DeepSeek v2 requires at least 103.0 GB at Q2_K, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
- What's the best quantization for DeepSeek v2?
For DeepSeek v2, Q4_K_M (144.3 GB) offers the best balance of quality and VRAM usage. Q5_K_M (170.8 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 103.0 GB.

- Can I run DeepSeek v2 on a Mac?
DeepSeek v2 requires at least 103.0 GB at Q2_K, 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 DeepSeek v2 locally?
Yes — DeepSeek v2 can run locally on consumer hardware. At Q4_K_M quantization it needs 144.3 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is DeepSeek v2?
At Q4_K_M, DeepSeek v2 can reach ~31 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 144.3 × 0.65 = ~36 tok/s
Estimated speed at Q4_K_M (144.3 GB)
~36 tok/s~36 tok/s~31 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of DeepSeek v2?
At Q4_K_M, the download is about 141.44 GB. The full-precision BF16 version is 471.48 GB. The smallest option (Q2_K) is 100.19 GB.
- Which GPUs can run DeepSeek v2?
No single consumer GPU has enough VRAM to run DeepSeek v2 at Q4_K_M (144.3 GB). Multi-GPU or professional hardware is required.
- Which devices can run DeepSeek v2?
6 devices with unified memory can run DeepSeek v2 at Q4_K_M (144.3 GB), including Mac Pro M2 Ultra (192 GB), Mac Studio (M3 Ultra, 256GB), Mac Studio (M3 Ultra, 512GB), Mac Studio M2 Ultra (192 GB).
