Frequently Asked Questions: Qwen 2.5 72B Instruct on NVIDIA GeForce RTX 5070 Ti (16GB GDDR7)
How much VRAM does Qwen 2.5 72B Instruct need on NVIDIA GeForce RTX 5070 Ti (16GB GDDR7)?
At standard 4-bit quantization (Q4_K_M) with 32K context, Qwen 2.5 72B Instruct requires 51.27 GB of total VRAM (weights + KV cache + CUDA runtime overhead).
What inference speed will Qwen 2.5 72B Instruct achieve on NVIDIA GeForce RTX 5070 Ti (16GB GDDR7)?
Based on NVIDIA GeForce RTX 5070 Ti (16GB GDDR7)'s 896 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.
