48GB VRAM

Mac M4 Pro 48G — what LLMs can it run?

90 of 112 indexed models fit comfortably in 48GB at 4K context, each at the highest-quality quant that still leaves headroom.

The short answer for Mac M4 Pro 48G

48 GB, 273 GB/s Unified LPDDR5X. 90 of 112 models in this index fit comfortably at 4K context; 92 load at all.

Biggest that fits
Nemotron 3.5 Bolt 74B-A9B — 23.1 GB at IQ2_XXS — 13.0 GB spare at 4K, so longer context comes out of a thin margin.
Room to grow
Nemotron 3.5 Lightning 30B-A3B — 19.8 GB at Q4_0 — under 60% of the card, which leaves 16.2 GB for a long context window or a second process.
Speed ceiling
Llama 3.1 8B Instruct at Q4_K_M reads 4.6 GB of weights per token, so 273 GB/s puts a hard ceiling near 59 tok/s. That is arithmetic on two published numbers, not a benchmark — real throughput lands below it. No run on this card has been measured here, so there is nothing to compare the ceiling against.
The wall you will hit
The GPU's share of unified memory, not the 48 GB on the box. macOS reserves part of the pool for the system and caps what a single process may wire down, so the practical budget is meaningfully below nameplate — the limit is adjustable (`iogpu.wired_limit_mb`) but it is not absent. Bandwidth is 273 GB/s, which is the number that decides tok/s once a model fits.

How this list is built

Each row is the lowest-perplexity-loss quant of that model whose estimated total — weights plus KV cache at 4K context plus activation buffer — uses at most 88% of the card. That is the calculator's "green" threshold, so every row here has real headroom rather than only just fitting. Raise the context length and the list shortens; the calculator lets you check any combination directly. The speed column is this card: a measured run, a range scaled from this card's own Llama 2 7B benchmark, or a bandwidth ceiling. A figure that only exists for the RTX 4090 is labelled as that card.

A further 2 models load but with no headroom to spare (up to 105% of VRAM) — the Quant Hub’s GPU chips count those too, which is why its number is higher.

Measured on this card

No benchmark runs in this index were recorded on a Mac M4 Pro 48G. Every figure on this page is calculated from the model architecture and the quant level — treat them as estimates, not measurements.

Cards with the same budget

What fits is decided by memory, so every 48GB card of this type returns the same list. These pages are not different answers — they differ in throughput, which this index does not measure per card.

Same list, different speed — play one sentence on both cards: Mac M4 Pro 48G vs Mac M3 Max 48G (Qwen3 32B Instruct)

Common questions

What is the best local LLM for a Mac M4 Pro 48G?

For everyday use, Nemotron 3.5 Lightning 30B-A3B at Q4_0 — about 19.8 GB of the card's 48 GB at 4K context, leaving 16.2 GB for a longer window. If you want the largest thing that will load, that is Nemotron 3.5 Bolt 74B-A9B at IQ2_XXS (23.1 GB, 13.0 GB spare). "Best" here means best fit for the memory budget — this index does not run task benchmarks, so it cannot tell you which model is smarter.

Can a Mac M4 Pro 48G run Llama 3.2 90B Vision Instruct?

No. Its smallest build here, Q3_K_M, needs about 46.2 GB and this card has 36.0 GB usable — short by 10.2 GB before any context beyond 4K. The largest model this card does clear is Nemotron 3.5 Bolt 74B-A9B.

How many tokens per second does a Mac M4 Pro 48G do on an 8B model at Q4?

This index has no measured run on this card, so it does not publish a figure. What can be stated from specifications: generating a token requires reading every weight once, Llama 3.1 8B Instruct at Q4_K_M is 4.6 GB of weights, and this card moves 273 GB/s — a ceiling near 59 tok/s. Batch size, context length, the runtime and how much of the model sits in cache all take you below it.

Mac M4 Pro 48G or L40S 48G for local LLMs?

They do not hold the same set: Mac M4 Pro 48G fits 90 and L40S 48G 96 of 112 at 4K — macOS keeps part of the Mac M4 Pro 48G's unified memory from the GPU, leaving about 36 GB usable. Speed is the other difference — 273 GB/s against 864 GB/s, a 3.2× gap in how fast the weights can be read, which is what token generation is bound by. The L40S 48G generates faster on any model both can hold.

90 of 112 indexed models fit comfortably in 48GB at 4K context, each at the highest-quality quant that still leaves headroom.
