Frequently Asked Questions: DeepSeek Coder V2 236B MoE on AMD Radeon RX 7900 XT (20GB GDDR6)
How much VRAM does DeepSeek Coder V2 236B MoE need on AMD Radeon RX 7900 XT (20GB GDDR6)?
At standard 4-bit quantization (Q4_K_M) with 32K context, DeepSeek Coder V2 236B MoE requires 151.34 GB of total VRAM (weights + KV cache + CUDA runtime overhead).
What inference speed will DeepSeek Coder V2 236B MoE achieve on AMD Radeon RX 7900 XT (20GB GDDR6)?
Based on AMD Radeon RX 7900 XT (20GB GDDR6)'s 800 GB/s memory bandwidth, expected decode speed is approximately 0 tokens per second.
Can I expand context beyond 32K tokens?
Each additional 32K tokens of context requires additional KV cache memory. For longer context windows, consider 8-bit or 4-bit KV cache quantization.
