Can I run DeepSeek-R1-0528 on AMD Radeon RX 7900 XTX (24GB)?

Compatibility verdict VRAM threshold engine

No, not enough memory would not load

No. DeepSeek-R1-0528 needs ~384.1 GB even at Q4_K_M, but AMD Radeon RX 7900 XTX (24GB) only has ~23 GB usable.

Needs ~384.1 GB Device usable ~23 GB

Needs ~384.1 GB even at Q4_K_M, but only ~23 GB is usable.

That figure is at a 4k context and moves about ±15% as context length changes.

The gap is about 361.1 GB: DeepSeek-R1-0528 needs roughly 384.1 GB at Q4_K_M and AMD Radeon RX 7900 XTX (24GB) leaves only about 23 GB usable for a model. No single tracked device has enough memory; DeepSeek-R1-0528 needs a multi-GPU or high-memory rig.

FAQ

Can AMD Radeon RX 7900 XTX (24GB) run DeepSeek-R1-0528?

No. DeepSeek-R1-0528 needs ~384.1 GB even at Q4_K_M, but AMD Radeon RX 7900 XTX (24GB) only has ~23 GB usable.

How much memory does DeepSeek-R1-0528 need?

AMD Radeon RX 7900 XTX (24GB) does not have enough memory. At Q4_K_M the weights are ~377.13 GB; with KV cache and runtime overhead, budget ~384.1 GB at a 4k context. It is a Mixture-of-Experts model (671B total / 37B active), so all experts must stay in memory; memory tracks total params, not active params.

What is the best tool to run DeepSeek-R1-0528 on Windows?

LM Studio for a simple setup; Ollama (CUDA) for the most speed. AMD GPUs run via Vulkan/ROCm at roughly half CUDA throughput. NVIDIA is the smooth path on Windows.
