FAQ & Reference

Frequently Asked Questions: DeepSeek-R1 Distill Qwen 14B on NVIDIA GeForce RTX 3090 (24GB GDDR6X)

How much VRAM does DeepSeek-R1 Distill Qwen 14B need on NVIDIA GeForce RTX 3090 (24GB GDDR6X)?

At standard 4-bit quantization (Q4_K_M) with 32K context, DeepSeek-R1 Distill Qwen 14B requires 13.16 GB of total VRAM (weights + KV cache + CUDA runtime overhead).

What inference speed will DeepSeek-R1 Distill Qwen 14B achieve on NVIDIA GeForce RTX 3090 (24GB GDDR6X)?

Based on NVIDIA GeForce RTX 3090 (24GB GDDR6X)'s 936 GB/s memory bandwidth, expected decode speed is approximately 63 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.
