A desktop built around one large-VRAM GPU is the fastest affordable way to run models locally. It is loud, hot, and bolted to the wall, and for the right person none of that matters.
A BitByteCore review — tested in real use, not summarised from a spec sheet.
A 14-inch Apple-Silicon Pro laptop runs surprisingly large models on battery, and that one fact reshapes how a developer works day to day. The catch is what you pay, and what you give up, to get there.

Our verdict
Single big-VRAM GPU desktop (local inference)
If you want fast local inference and you do not need to carry it anywhere, a desktop built around a single large-VRAM GPU is the most direct answer there is. The whole design philosophy is one part: a GPU with as much fast video memory as you can justify, fed by an ordinary CPU and ordinary RAM. Everything else in the box exists to keep that card cool and powered. Get the card right and the rest is supporting cast.
The reason this works is bandwidth. A dedicated GPU pairs its compute with memory that is enormously faster than system RAM, and language-model inference lives and dies on memory bandwidth. So a model that fits inside the card's video memory runs fast: tokens stream quicker than you read, long contexts process without a long wait, and you can batch several requests before the machine sweats. This is the experience the mini-PC and the integrated-graphics laptop cannot deliver, because they share slower system memory.
The flip side is a hard, unforgiving line. A model that fits in video memory flies. A model one gigabyte too large does not run at all, or spills into system memory and crawls so badly you will not use it. There is no graceful middle. This makes VRAM capacity the single most important number when you buy, and it is the number you cannot change later without buying a whole new card. Decide how big a model you intend to run, find the card whose memory holds it with headroom, and buy that. Skimping here is the one mistake that ruins the machine.
This is a box that stays on a desk and plugs into a wall, and under load it gets loud and warm. That is the deal. In exchange you get an inference machine that embarrasses any laptop, that you can leave running as a server on your network, and that you can upgrade piece by piece over the years. You can swap the card when a bigger one makes sense, add memory, change the CPU. A laptop is a sealed decision. This is a platform you maintain.
Unlike most of its rivals in this roundup, this machine can also train and fine-tune, not just serve. It will not match a rack of data-center accelerators, but for learning, for small fine-tunes, and for real experimentation it is capable in a way the Apple laptop and the mini-PC simply are not.
This is for the person who wants the fastest local inference per dollar, who does serious or sustained AI work at a desk, and who wants the option to fine-tune as well as serve. It is for anyone who would rather invest in an upgradeable platform than a sealed laptop, and who is unbothered by noise and heat in exchange for speed. If your AI work is heavy and stationary, this is the most rational build.
It falls short on portability, obviously and completely. It also falls short for anyone whose target model is bigger than a single consumer card's memory, where you are pushed toward multi-GPU complexity or back to the cloud. And it is overkill for light, occasional AI use, where a quiet laptop would do the job without the noise, heat, and power bill.
The verdict: for fast, affordable, stationary local inference, a single big-VRAM GPU desktop is the machine to beat. Size the video memory to your model with room to spare, and accept the noise and the tether. Get the VRAM wrong and nothing else you spent will save it.
A high-memory mini-PC with integrated graphics can hold a large model in shared memory and serve it to your whole network. It is a clever, cheap idea with one hard wall: memory bandwidth.
