Laptop or desktop for local LLMs?
Last updated
For a laptop or desktop for local LLMs, pick the desktop unless you must run models offline on the move. Desktops give more memory per dollar, cool better and can serve every device you own. Olares One puts a laptop GPU in a small server.

Laptop or desktop for local LLMs: what do you trade?
Portability against memory, cooling and price. A laptop fits its GPU, memory and cooling into a thin body that also runs on battery. A desktop has room for bigger GPUs, more memory and larger fans. For local LLMs memory is the constraint, and laptop memory usually cannot be upgraded after purchase.
A 32B model needs about 19-20 GB and a 70B model about 40 GB (approximate rule of thumb at 4-bit). Laptops with that much GPU or unified memory sit at the top of their makers' ranges.
What does a laptop GPU give up?
Memory and power. NVIDIA sells mobile and desktop chips under the same name, and they differ. NVIDIA lists the desktop RTX 5090 with 32 GB of GDDR7 at 575 W total graphics power. The RTX 5090 Mobile in Olares One has 24 GB of GDDR7 at a 175 W max TGP, according to Olares' product page.
Laptop makers set their own power limits for a mobile GPU, so check the figure for any laptop you consider. Apple laptops use unified memory like the Mac Studio, so the memory option you order sets the model size.
Is there an option between a laptop and a desktop?
Yes, a small server plus the laptop you already own. The model runs on the server, and every laptop, tablet or phone connects to it. Most people do not need the model inside the laptop, only reachable from it. That keeps the laptop light and leaves its battery for other work.
Olares One is built for this. It runs the RTX 5090 Mobile at its full 175 W limit in a 2.15 kg box with a 330 W adapter. Olares' FAQ says you can query its models from an iPhone or Mac anywhere through secure remote access, and that LM Studio on a laptop can use models hosted on the server through its API.
Which should you choose?
We recommend a desktop or a small server for almost everyone, and a laptop only for people who work offline away from a desk. If you use several devices or share the model, the small server is the better buy. Olares One is our pick there, despite its 24 GB limit for dense models above about 32B.
The desktop guide covers single-desk machines, and Mac or PC covers the platform.
Questions & answers
Can a gaming laptop run local LLMs?
Yes, within its VRAM. Check the exact GPU memory before buying, since laptop GPUs often have less than desktop cards with similar names.
Is Olares One a laptop?
No. It uses the laptop-class RTX 5090 Mobile inside a 320 x 197 x 55 mm box that runs as a server. You reach it from your own laptop or phone.
