Can I run Qwen2.5 14B on NVIDIA RTX 4060 Ti 16GB?
Yes: Qwen2.5 14B runs on NVIDIA RTX 4060 Ti 16GB with Q5_K_M at roughly 15 tokens/s. Estimated memory 12.2 GiB at 8,192 tokens of context.
With Q5_K_M you can push the context to about 13,056 tokens before memory runs out (F16 KV cache).

NVIDIA RTX 4060 Ti 16GB offers about 16 GiB of memory (92% usable for a model) at 288 GB/s. Speed is a bandwidth-bound estimate of single-stream generation at 65% efficiency; real results vary by runtime, drivers and settings, so measure on your machine.
How this is calculated
Weights ≈ parameters × bits per weight ÷ 8. KV cache ≈ 2 × 48 layers × 8 KV heads × 128 head dim × 2 bytes per token. Decode speed ≈ efficiency × memory bandwidth ÷ bytes read per token. Learn the maths in VRAM math and memory bandwidth, or try the VRAM calculator.
