RTX 4060 Ti 16GB LLM Calculator — What Can It Run?
Check which models fit on a RTX 4060 Ti 16GB: max parameters per precision, cache headroom and estimated tokens/sec.
RTX 4060 Ti 16GB: 16 GB, 288 GB/s, ~22.1 TFLOPS FP16. The 4060 Ti 16GB pairs generous VRAM with an unusually narrow 128-bit bus (288 GB/s) — it FITS mid-size models that embarrass pricier cards, then generates noticeably slower than a 3090 on the same model.

About RTX 4060 Ti 16GB LLM Calculator — What Can It Run?
"Will it run?" is the first question of local AI, and for the RTX 4060 Ti 16GB this calculator answers it precisely: enter any model's parameter count and quantization and get the memory bill against this card's 16 GB, the largest model it can hold at that quant, and a bandwidth-derived decode-speed estimate (token generation streams the whole model per token, so 288 GB/s is the speed limit that matters). The 4060 Ti 16GB pairs generous VRAM with an unusually narrow 128-bit bus (288 GB/s) — it FITS mid-size models that embarrass pricier cards, then generates noticeably slower than a 3090 on the same model.

Frequently asked questions
Why does my 4060 Ti generate slower than an older 3090?+
Token generation is memory-bandwidth-bound: every token streams the whole model from VRAM. The 3090 moves 936 GB/s versus the 4060 Ti's 288 GB/s — 3.2× — so the older card decodes roughly 3× faster despite similar capacity at 4-bit.
What models suit a 16 GB card best?+
FP16 7–8B models (~15 GB, tight), Q5/Q6 13–14B models (~10–12 GB) with healthy contexts, or Q4 20B-class models. It is also a sweet spot for Stable Diffusion XL and QLoRA fine-tuning of 7B models, where capacity beats bandwidth.
How is the tokens/sec estimate for the RTX 4060 Ti 16GB derived?+
Decode is memory-bound: each token reads every weight once, so speed ≈ effective bandwidth ÷ model size. We assume ~60% of the 288 GB/s peak is achievable, matching llama.cpp benchmarks within ~20%. Prompt prefill is compute-bound and much faster per token.
Why reserve memory beyond the weights?+
The KV cache grows with context (use our per-model KV-cache calculators), CUDA/Metal runtimes take hundreds of MB, and allocator fragmentation wastes more. The default reserve suits 2–8K contexts; long-context work needs significantly more.
