The RTX 5070 brings Blackwell architecture to the mid-range. At 59 tokens per second for 8B models, it edges out the 4070 SUPER while keeping 12GB VRAM. Best for users prioritizing speed with 7B-9B models.
12GB GDDR7 at 672 GB/s makes the RTX 5070 the fastest 12GB card for AI inference. Compared to the RTX 4070 SUPER (504 GB/s), bandwidth jumps 33%. This directly translates to faster token generation: 59 tok/s vs 56 tok/s. The 12GB limit means 14B models still require quantization tricks. For 7B-9B workloads, this is the sweet spot if you do not need the extra VRAM.

The RTX 5070 has 12GB GDDR7 VRAM with 672 GB/s bandwidth — 33% faster than the RTX 4070 SUPER. About 11.5GB is usable for model loading. Best suited for 7B-9B models at Q4 quantization.
Up to 9B parameter models at Q4 quantization. This includes Qwen 2.5 7B, Llama 3.2 8B, Mistral 7B, and Gemma 2 9B. The RTX 5070 runs them all at 59 tok/s — the fastest 12GB card available.
The RTX 5070 is the best 12GB card for local AI in 2026. Blackwell architecture and GDDR7 deliver 59 tok/s — 40% faster than the RTX 3060. At $579, it offers strong value if 7B-9B models meet your needs.
If you want to run 14B models, get the 5070 Ti (16GB). If 7B-9B models are enough, the RTX 5070 saves $170 and is only 32% slower than the Ti. The Ti also has 33% more bandwidth (896 vs 672 GB/s).
The RTX 5070 is 40% faster (59 vs 42 tok/s) with the same 12GB VRAM. However, the 3060 costs less than half the price. For budget builds, the 3060 remains excellent. For best speed at 12GB, the 5070 wins.
