Best GPU for local AI

Which AI models can the RTX 5070 run?

The RTX 5070 has 12 GB of graphics memory, read at 672 GB/s. In a desktop with 32 GB of DDR5-6000, 34 of the 88 open models here run entirely on the card, 34 of them writing faster than you read; the most capable it runs well is Qwen3 14B at Q4_K_M, 40–64 tokens/s. 29 more run with part of the model in system memory, more slowly.

Every figure is for an 8,192-token conversation (about 6,000 words), at the best compression that fits. Try it in the calculator with your own memory, conversation length and compression, or a second card. For image and video models, see Stable Diffusion, FLUX and Wan on the RTX 5070.

Models that run entirely on the card

The fastest way to run a model: all of it in graphics memory. Most people read at 5 to 8 tokens a second, so anything above 10 feels quick.

With help from system memory

In a desktop with 32 GB of DDR5-6000, these fit with part of the model in system memory. The processor reads that part several times more slowly, so they write more slowly the more of them is off the card.

The other 25 need more memory than a desktop with 32 GB of DDR5-6000 has; the calculator shows what more memory, or a second card, would add.

Two RTX 5070s

Two of them pool 24 GB, enough for 52 of the models entirely on the cards, 18 more than one holds. The most capable that runs well is Qwen3 32B at Q4_K_M, 19–30 tokens/s. A second card adds memory, not speed: a model that already fits on one runs no faster on two.

How it is worked out

Writing an answer is limited by memory rather than arithmetic: for every word-piece (token) a model writes, the computer reads every weight that token uses once. So the speed is how fast the memory holding the model can be read, divided by how much is read for each token: the model’s weights at the chosen compression, plus the conversation so far. How much of its memory speed each graphics card reaches is measured, not assumed: it comes from the card’s own result in llama.cpp’s benchmark, which LM Studio, Ollama and Jan are built on. A model that does not fit in the graphics card’s memory spills into system memory, five to fifteen times slower, and one that does not fit in memory at all can be read from the drive as it runs, slower again; the estimate counts each part at its own speed, and a processor with few threads cannot use all of fast memory. Graphics built into a processor use system memory, at its speed. Reading a prompt is limited by arithmetic, so it follows the measured prompt speed.

Already running a model? See if it runs at full speed

A model that is slower than it should be is nearly always partly on the processor rather than all on the graphics card, which is several times slower — and Ollama does that without a word when something else holds the card’s memory. Bottleneck’s free app checks a model run with Ollama, LM Studio, llama.cpp, KoboldCpp or Jan: where it really runs, how fast it writes, and what your PC should manage with it. Nothing leaves your PC. Or check and fix it by hand.

It reads your parts too: the graphics card and how much memory it really has free, how much system memory is installed, the speed it runs at and in how many channels. Memory left in one channel, or below its rated speed, halves how fast a model runs from it, and Bottleneck says so. Its AI models screen then lists what runs on this PC.

The free version shows where a model runs and how fast, with no time limit and no account. Pro, $9 once, explains why it is slower than it could be and how to fix it. Compare the versions
