Can Desktop PC · 2× GeForce RTX 3090 (48 GB) · 128 GB RAM run Qwen2.5-Coder 7B Instruct?

48 GB VRAM + 128 GB RAM · 936 GB/s memory bandwidth · Qwen2.5-Coder 7B Instruct has 7.6B parameters.

Short answer

Yes, excellent for chat and acceptable or better for every workload we test.

Best quantization for chat: Q6_K (6.0 GB of weights) on Ollama. Generation: 70–120 tok/s, leaving about 40 GB free for your other apps.

How it rates for each workload

Same model and machine, different jobs. Agents and long documents send far bigger prompts than chat, so they need much more speed and memory.

Speeds are bandwidth-based estimates; no direct benchmark exists for this pair. “First reply” is the time to read the workload’s opening prompt. How we calculate

Get it running

Copy-paste commands for the Q6_K build with a 32K context. Ollama and llama.cpp download the file straight from Hugging Face.
