Frequently Asked Questions: Qwen 2.5 Coder 32B Instruct on NVIDIA DGX Spark (128GB Grace-Blackwell Unified)
How much VRAM does Qwen 2.5 Coder 32B Instruct need on NVIDIA DGX Spark (128GB Grace-Blackwell Unified)?
At standard 4-bit quantization (Q4_K_M) with 32K context, Qwen 2.5 Coder 32B Instruct requires 25.22 GB of total VRAM (weights + KV cache + CUDA runtime overhead).
What inference speed will Qwen 2.5 Coder 32B Instruct achieve on NVIDIA DGX Spark (128GB Grace-Blackwell Unified)?
Based on NVIDIA DGX Spark (128GB Grace-Blackwell Unified)'s 273 GB/s memory bandwidth, expected decode speed is approximately 9 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.
