NVIDIA GeForce RTX 4060 Ti 16GB
Runs downloadable LLMs up to ~19.5B at Q4, ~46.9-55.9 tok/s on an 8B model.
What you can run
At 8k context, FP16 KV. Full-speed tok/s holds up to "max ctx"; beyond it the context spills to system RAM (CPU/PCIe offload) and drops to the degraded figure.
| Model size | FP16 | Q8 | Q4 |
|---|---|---|---|
| 3B |
35-41.8 t/s ≤110k ctx · then ~4.9-5.8 (slow) |
70.1-83.5 t/s ≤156k ctx · then ~9.7-11.6 (slow) |
125.1-149.1 t/s ≤176k ctx · then ~17.4-20.7 (slow) |
| 7-8B | won't run |
26.3-31.3 t/s ≤40k ctx · then ~3.7-4.4 (slow) |
46.9-55.9 t/s ≤67k ctx · then ~6.5-7.8 (slow) |
| 13B | won't run |
16.2-19.3 t/s ≤1k ctx · then ~2.2-2.7 (slow) |
28.9-34.4 t/s ≤36k ctx · then ~4-4.8 (slow) |
| 32B | won't run | won't run | won't run |
| 70B | won't run | won't run | won't run |
| 120B | won't run | won't run | won't run |
| 400B | won't run | won't run | won't run |
Estimate: tok/s ≈ bandwidth ÷ (params × bytes/param) × efficiency (NVIDIA). Cyan = fits ~14.7 GB usable. Beyond "ctx", KV spills to system RAM (CPU/PCIe offload) (rough degraded speed shown).

About the NVIDIA GeForce RTX 4060 Ti 16GB
NVIDIA GeForce RTX 4060 Ti 16GB is a discrete GPU from NVIDIA on Ada Lovelace, 2023. For local genAI the numbers that matter are its 16 GB (how big a model + context fits) and 288 GB/s bandwidth (generation speed). Plan for a ~550W power supply.
Frequently asked questions
What size LLM can the NVIDIA GeForce RTX 4060 Ti 16GB run?▶
With ~14.7 GB usable it runs up to ~19.5B at Q4 (~6B at FP16) at 8k context. Bigger spills into system RAM (CPU/PCIe offload) and slows sharply.
How many tokens/sec does the NVIDIA GeForce RTX 4060 Ti 16GB generate?▶
Generation is bandwidth-bound. At 288 GB/s an 8B model at Q4 runs ~46.9-55.9 tok/s (estimate).
Why does long context slow it down?▶
The KV cache for the context must also fit fast memory; once weights+KV exceed 14.7 GB it spills to system RAM (CPU/PCIe offload) and throughput collapses. Each row shows the max usable context.
What else do I need to run the NVIDIA GeForce RTX 4060 Ti 16GB?▶
Besides the card: a ≥550W 80+ Gold power supply, at least 16GB of system RAM (2× the 16GB VRAM is ideal for CPU offload), a free PCIe x16 slot, any modern multi-core CPU, and a ≥1TB NVMe SSD for model weights.
