# NVIDIA GeForce RTX 5070 Ti for local LLMs

> The best value in the RTX 50 lineup for 16GB of fast CUDA memory.

The RTX 5070 Ti has 16GB of GDDR7 and 896 GB/s of memory bandwidth, which decides how big a model fits and how fast it generates text. It comfortably runs models up to about 15B parameters: the largest in our catalog is Phi-4 at Q5_K_M (13GB with 8K context, ~63 tokens/sec). Our top all-round pick for it is Qwen3.8 27B (Q3_K_M, ~51 tokens/sec).

## Key specs

- Memory: 16GB GDDR7
- Memory bandwidth: 896 GB/s
- Architecture: Blackwell (2025)
- Power: 300W
- Typical price: ~$1,200 (checked 2026-10)
- Software: CUDA, Vulkan

## Best models for this GPU

- **Best overall (also coding, reasoning, vision, largest that fits):** Qwen3.8 27B at Q3_K_M, ~14.8GB with 8K context, ~51 tokens/sec
- **Runner-up:** Qwen3.5 9B at Q8_0, ~12.0GB with 8K context, ~62 tokens/sec
- **Fastest good model:** Gemma 4 26B A4B at Q3_K_M, ~14.1GB with 8K context, ~145 tokens/sec

## Pros
- Nearly RTX 5080 bandwidth for less money
- 16GB of GDDR7 at 896 GB/s
- Full CUDA and FP4 support
- 300W is easier to power and cool than the 5080 or 5090

## Cons
- 16GB rules out 32B dense models without offload
- Street price about $450 over MSRP
