What LLMs can I run on 48 GB of VRAM?

On a 48 GB GPU, 12 catalog models run fully on the GPU at an 8,192-token context. The most capable is Hunyuan-A13B-Instruct at IQ4_XS (needs ~46.2 GiB). Pick a smaller model or a lower quant for more headroom.

Figures assume a 48 GB GPU paired with 32 GB of system RAM (a typical desktop), judged at an 8,192-token context. Speed depends on the specific card — this page ranks by fit, not speed.

TL;DR

48 GB is where the 70B class finally runs fully on the GPU. Dense models in that class fit at compact 4-bit quants, the biggest mixture-of-experts models in the catalog squeeze in, and the whole 30B class runs at near-lossless quants with room to spare. The list below is derived live from the fit engine, largest first.

One card or two?

Plenty of people reach this tier with two 24 GB cards rather than one workstation card. For fit, that mostly works: llama.cpp splits a model's layers across GPUs, so as a rule of thumb the combined memory is your budget, minus a little overhead per card. The verdicts on this page assume a single 48 GB pool, so treat them as close-but-not-exact for a split rig — and expect some speed cost from crossing between cards, especially in interactive use.

Frequently asked

Can I really run 70B-class models on 48 GB?

Yes — fully on the GPU at compact 4-bit quants, at moderate context. That's the headline this tier earns. Near-lossless quants of that class are beyond 48 GB, and long contexts eat the remaining margin quickly, so check your intended window in the fit calculator before committing to a very large download.

Does 2×24 GB behave like a single 48 GB card?

For fit, roughly — llama.cpp can split a model's layers across the cards, so the combined memory is what mostly matters, minus a little per-card overhead. Speed is the difference: moving between cards costs something, and two cards rarely match one card of the same total memory. The verdicts here assume a single pool; treat them as a close guide for a split rig, not a guarantee.

Is a 70B-class model at 4-bit better than a 30B-class one near-lossless?

For raw capability, usually — parameter count generally beats bit-depth at these scales. But the 30B-class option generates faster, leaves generous room for context, and at near-lossless quants tracks its original model closely. If your work is interactive or long-context, the smaller model often wins in practice; test both on your task.

Does context length change what fits in 48 GB?

Yes, and it bites hardest here — the KV cache grows with both context and model size, so the 70B-class entries that barely fit at this page's context are the first to stop fitting at longer ones. Verify your model, quant, and target context together in the fit calculator.

Will these models be fast on my hardware?

This page ranks by fit, not speed. 48 GB setups span workstation cards, older server cards, and dual-card rigs, and their memory bandwidth differs widely — so identical fit verdicts can come with very different generation speeds. Check your specific card's GPU page for speed context.
