Frequently Asked Questions: DeepSeek-R1 Distill Qwen 32B on AMD Radeon RX 7900 XTX (24GB GDDR6)
How much VRAM does DeepSeek-R1 Distill Qwen 32B need on AMD Radeon RX 7900 XTX (24GB GDDR6)?
At standard 4-bit quantization (Q4_K_M) with 32K context, DeepSeek-R1 Distill Qwen 32B requires 25.41 GB of total VRAM (weights + KV cache + CUDA runtime overhead).
What inference speed will DeepSeek-R1 Distill Qwen 32B achieve on AMD Radeon RX 7900 XTX (24GB GDDR6)?
Based on AMD Radeon RX 7900 XTX (24GB GDDR6)'s 960 GB/s memory bandwidth, expected decode speed is approximately 6 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.
