Frequently Asked Questions: Meta Llama 3.1 8B Instruct on NVIDIA GeForce RTX 5070 Ti (16GB GDDR7)
How much VRAM does Meta Llama 3.1 8B Instruct need on NVIDIA GeForce RTX 5070 Ti (16GB GDDR7)?
At standard 4-bit quantization (Q4_K_M) with 32K context, Meta Llama 3.1 8B Instruct requires 7.87 GB of total VRAM (weights + KV cache + CUDA runtime overhead).
What inference speed will Meta Llama 3.1 8B 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 114 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.
