Best Computer for Local LLM
Last updated
Best Computer for Local LLM names Olares One its editorial choice for local LLMs on a shared server up to about 32B, with CUDA, 24 GB VRAM and server software. For one person on 70B or larger, a Mac Studio or DGX Spark holds more.

Why is Olares One our choice of computer for local LLMs?
It is our choice when you want models up to about 32B served to several people or devices, on CUDA, without building a server. Olares One pairs an RTX 5090 Mobile with 24 GB of VRAM and Olares OS. The OS installs Ollama and Open WebUI in one click and adds user accounts and remote access.
Olares' own test gives a sense of the speed. Qwen3-30B-A3B ran at 157 tokens per second for one request, and at about 81 tokens per second each with 8 requests at once.
At 4,999 USD on Olares' shop (13 November 2026) it is not cheap. Dense models above about 32B at 4-bit spill out of 24 GB into slower system memory. For one person running 70B or larger, we'd pick a Mac Studio M5 Ultra, which Apple lists from 96 GB of unified memory, or a DGX Spark with 128 GB. A used RTX 3090 tower gives the same 24 GB for less, if you build it.
How should you use this reference?
Use it to match a machine to the model you want to run. Each guide answers one question buyers type before they choose a computer for local LLMs. Olares One is the featured machine. The others appear with the specs and prices their makers publish, read on 12 and 13 November 2026, so the comparison stays factual.

What should you verify before buying?
Verify the model size, the software and the price on the day. Write down the largest model you plan to run and check it against the memory you are buying. Check that your tools run on the platform, because CUDA, Apple Metal and AMD each have gaps. Several machines here were on sale when we read them.
For sizing, plan on about 0.5-0.6 GB per billion parameters plus a few GB for context (approximate rule of thumb at 4-bit). Treat every maker's speed figures, Olares' included, as a starting point until independent tests agree.

Read the entry ↗Questions & answers
How much memory do I need to run a local LLM?
At 4-bit, roughly: 8B needs about 5 GB, 14B about 9 GB, 32B about 19-20 GB, 70B about 40 GB and 120B about 65 GB. These are approximate and leave little room for long context.
Is VRAM or unified memory better for local LLMs?
VRAM on an NVIDIA card is fast and works with CUDA tools. Unified memory on a Mac or a Ryzen AI Max+ 395 box gives far more capacity in one machine. Pick VRAM for speed and tooling, unified memory for size.
Why not buy the biggest Mac Studio instead?
If you work alone and want 70B or larger models, a Mac Studio M5 Ultra is a strong choice. It has no CUDA, and macOS is not set up to serve many users at once. Olares One fits shared use up to about 32B.
