Can I Run Llama 3.1 70B on NVIDIA GeForce GTX 1660 Ti?
Sort of — NVIDIA GeForce GTX 1660 Ti can run Llama 3.1 70B (Q5_K_M) only by spilling layers to RAM. Generation will be slow.
Estimated ~2 tokens/sec on the Q5_K_M quantization.
Hybrid CPU+GPU
Best variant: Q5_K_M
CPU + GPU hybrid — not enough VRAM (6 GB < 50 GB min), but 64 GB RAM is sufficient. Expect significantly slower inference.
