Can I run Llama 3.3 70B on the GeForce RTX 5060 Ti 16GB?

Won't runQ4_K_M needs 45.2 GB, 29.8 GB more than the 15.4 GB of usable memory. Q2_K (heavy quality loss) works instead: Runs slowly, est. 2.5 tok/s (2.0–3.1, calibrated estimate ±20%).

16 GB VRAM · 448.0 GB/s · FP16 23.7 TFLOPS. Assumes 32 GB of DDR5-5600 system RAM, Windows with this GPU driving the display, 8k context and an f16 KV cache.

Verdict by system RAM

This page assumes 32 GB of system RAM. The verdict stays the same, but which file fits in memory depends on how much system RAM you have.

How to run it

Commands for the Q2_K file. Both tools download from Hugging Face on first run.

These commands assume 32 GB of system RAM. For a different amount of RAM, pick it under “System RAM, context length and KV cache” above to see the commands for it.

File: Llama-3.3-70B-Instruct-Q2_K.gguf (26.38 GB) from bartowski/Llama-3.3-70B-Instruct-GGUF.

llama.cpp
llama-server -hf bartowski/Llama-3.3-70B-Instruct-GGUF:Q2_K -c 8192 -ngl 36 -fa on
  • -ngl 36 puts 36 of 80 layers on the GPU; if VRAM overflows, lower it by 1–2.
  • -fa on enables flash attention (needed for KV cache quantization).
  • --cache-type-k q8_0 --cache-type-v q8_0 shrinks the KV cache to 1.44 GB at 8k context.
Ollama

PowerShell (quit the Ollama tray app first):

$env:OLLAMA_CONTEXT_LENGTH="8192"; ollama serve
ollama run hf.co/bartowski/Llama-3.3-70B-Instruct-GGUF:Q2_K
  • Ollama defaults to 4k context on GPUs under 24 GB. Set OLLAMA_CONTEXT_LENGTH when starting the server, or /set parameter num_ctx inside the chat.
  • Ollama splits layers between GPU and CPU automatically.
  • /set parameter num_ctx 8192

Frequently asked questions

Can I run Llama 3.3 70B on the GeForce RTX 5060 Ti 16GB?

Q4_K_M needs 45.2 GB, 29.8 GB more than the 15.4 GB of usable memory. Q2_K (heavy quality loss) works instead: Runs slowly, est. 2.5 tok/s (2.0–3.1, calibrated estimate ±20%). Q2_K needs 29.3 GB at 8k context; this setup has 15.4 GB of usable memory and 28.0 GB of free system RAM.

How much context can Llama 3.3 70B use on the GeForce RTX 5060 Ti 16GB?

At Q2_K the verdict stays Runs slowly up to 16k context with an f16 KV cache (5.4 GB of KV) and up to 16k with a q8_0 KV cache (2.9 GB). The model supports up to 128k.

Which quant should I use, and how fast is it?

Q2_K (heavy quality loss) (26.38 GB) is the recommended balance: Runs slowly, est. 2.5 tok/s (2.0–3.1, calibrated estimate ±20%). It is also the largest tracked file that gets this verdict.

Speeds are estimates from memory bandwidth, calibrated against public benchmarks, and each one comes with an error band and a confidence label. Real results vary with drivers, backend, context length and thermals.
