NVIDIA RTX 4060 Ti 16GB vs NVIDIA RTX 4080 Super for local LLMs
8 reports on the NVIDIA RTX 4060 Ti 16GB and 6 on the NVIDIA RTX 4080 Super
Which is faster for local LLMs?
On Qwen3.8 27B at 3-bit, the NVIDIA RTX 4060 Ti 16GB runs at 20.0 tokens per second (one run) and the NVIDIA RTX 4080 Super at 33.1 (one run). Those are community reports whose engines and settings differ, so the gap is a rough sign, not a controlled measure of the two cards. Memory bandwidth, which caps how fast a card can write, is 2.6x higher on the NVIDIA RTX 4080 Super (288 GB/s on the NVIDIA RTX 4060 Ti 16GB, 736 on the NVIDIA RTX 4080 Super).

Measured on both
Median tokens per second from plain runs (one device, one request, no speculative decoding, the whole model in the device's memory) of the same model size at the same quant level. Engines and context lengths can still differ between the runs. How to read these

Estimated by the calculator
The quant the calculator recommends for each card and its estimated speed at a 32,768-token context with 32 GB of system RAM, from memory bandwidth and the model's shape. Where a model was also measured above, the measurement wins.
