What can you run with 24 GB of memory?

A model does not get the 24 GB. On the Mac mini M6, 24GB it gets 16 GB and on the GeForce RTX 3090, 24GB it gets 23 GB, because the system keeps a share of one and the card keeps a margin free on the other. That is 13 of the 39 current models at 32k of context on the first and 24 on the second, and the strongest of them is Qwen3.8 27B.

The machines sold with 24 GB

There are seven machines here with 24 GB, and what they hand a model is not the same figure. The fourth column is what each one holds at 32k of context, and it is the number that machine's own page prints.

List prices, and the memory each maker publishes. A machine marked previous is one that is no longer sold, priced at what it launched at. Graphics cards are priced as the card alone, so add the PC around one before comparing it with a complete computer. All seven cards here are ranked by what each one holds.

Models that fit in 24 GB

Every current model the roomiest 24 GB machine here holds at 32k of context, strongest first. The third column is the whole job at once: the weights plus the cache for 32k of context. The fourth says how many of the machines at this size have room for it, which is the part a size on its own cannot tell you. Speeds are on the GeForce RTX 3090, 24GB, the machine this list is cut from, which is no longer sold; speed follows memory bandwidth rather than memory size, so another machine at 24 GB runs the same model at its own rate, and its page gives every one of them.

For scale, the calculator starts from 80 tok/s for a hosted API and times a local machine against it. 16 of the 24 above reach it, and the slowest is 36 tok/s.

Superseded models are left out of the count, because what a machine is worth buying for is what you would run on it today; the leaderboard ranks every model this site lists, older ones included. Where the cache figure comes from is one section of the memory guide.

What 32 GB adds over 24 GB

The machine here with 32 GB that hands a model the most of it is the Radeon AI PRO R9700, 32GB, at 31 GB, and it holds 27 of the 39. At 24 GB the most is 23 GB, on the GeForce RTX 3090, 24GB, holding 24. The step adds Granite 4.2 30B, Gemma 4 31B it and Nemotron 3.5 Lightning 30B-A3B. The strongest either way is Qwen3.8 27B.

The cheapest machine at 32 GB is the Strix Halo Framework Desktop, 32GB at $1,269. The cheapest at 24 GB is the Mac mini M6, 24GB at $1,099, so the step costs $170.

Both sides are read off the machine at each size that hands a model the most, so the comparison is the best case against the best case. The table above has every machine at 24 GB and what each of them holds.

How much context 24 GB leaves room for

The cache grows with the window you ask for, so the same machine holds fewer models the longer the context. One column here for each amount a 24 GB machine hands over. A model is counted only where its own context ceiling reaches that far.

Counted over the 39 current models, at the quantisation each is listed at and with the cache at 16 bits. The calculator has a switch for a smaller cache, which changes both what fits and how fast a long window runs.

Does a 24 GB machine pay for itself?

On the Mac mini M6, 24GB at $1,099, the cheapest machine at 24 GB with a published price, the model that pays it back soonest at 500k tokens a day is Ministral 3 14B, in 34 years. At 20M tokens a day, agents running most of the day, it is Ministral 3 8B in 15 months. The Mac mini M6, 24GB cannot generate 20M tokens in a day; it manages 18.1M, so that figure is for the most it can do.

The sum is the same everywhere on this site: what the same work costs to rent, less what the electricity costs to generate it, against the price of the machine. The best buys rank the quickest pay-back at every level of use, and what it costs a month puts the machine and the API bill in the same shape.

Put your own usage in

Every figure is at 32k of context unless the row says otherwise, with the cache at 16 bits and each model at the quantisation this site lists it at. Weights are the published file sizes on each model's page, and the cache is worked out from the architecture recorded there. What a model gets is the memory the GPU can address, which each machine's page explains. Speeds say whether anybody measured them; where they were not, they are worked out from memory bandwidth. To change the context, the quantisation or the price you would pay, open the calculator. For the sizes either side of this one, the memory guide has the ladder in full.
