Nvidia DGX Spark as a daily driver

一句话概要

I bought an NVIDIA DGX Spark! It’s actually quite a competent general purpose computer while being super tiny and power efficient. It basically just has an ARM CPU, a decent NVIDIA GPU (with the same number of CUDA cores as the RTX 5070), 128 GB of unified memory, and a 4 TB SSD.

I bought an NVIDIA DGX Spark! It’s actually quite a competent general purpose computer while being super tiny and power efficient. It basically just has an ARM CPU, a decent NVIDIA GPU (with the same number of CUDA cores as the RTX 5070), 128 GB of unified memory, and a 4 TB SSD.

The DGX Spark runs “DGX OS” but it is in fact just plain old Ubuntu 24.04 with some additions. If you want, you can just install another Linux distribution easily (Fedora works well), although there may be a couple of weird bugs with the Realtek Ethernet driver so the NVIDIA version of the Linux kernel has a couple of patches. Unlike some other ARM devices, the DGX Spark is all ACPI rather than device tree based, so regular Linux builds for arm64 work just fine.

Generally, it is a power-efficient and quiet box (it gets slightly audible under load, but no annoying whine, and is silent when idle). It’s really nice how it doesn’t heat up the room or make noise. Stuff like web browsing and general programming work are super fast.
