Building a Mini-ITX PC is a fantastic way of saving desk space and encouraging portability without sacrificing performance, thanks to a range of graphics cards squeezing into smaller form factors. We've rounded up the best GPUs for a Mini-ITX PC build and some alternatives to suit your budget.
Best overall
The NVIDIA GeForce RTX 3080 is still the best graphics card overall, with the EVGA XC3 Ultra measuring just under 286mm. It'll be a squeeze for a Mini-ITX PC case but still a realistic choice when paired with proper cooling.
AMD alternative
If you prefer AMD to NVIDIA, the RX 6800 XT is a fantastic alternative to the GeForce RTX 3080. Gigabyte's offering has a 286mm length and 118m width but would still fit into a Mini-ITX case like the HYTE Revolt 3.
Ultra compact
EVGA brings the ultimate space-saver that proved capable in our NVIDIA GeForce RTX 3060 Ti review in the form of their XC Gaming model. Measuring a mere 202mm in length, it's perfect for a small form factor gaming PC or media center.
ITX sweet spot
Compared to the official NVIDIA GeForce RTX 3070 model, the MSI Ventus 2x OC is more compact with a 232mm length, perfect for an ITX build. The ideal middle ground for most gamers, the RTX 3070 is still a strong choice.
Budget NVIDIA
This GTX 1660 Super variant from MSI measures a tiny 179mm in length and provides admirable performance for the price. Well suited for a compact case, the Aero ITX is perfect for 1080p gaming.
Budget AMD
Another AMD alternative, the Sapphire RX 6600, measures 193mm in length, 193mm in width, and 41mm in height. It'll fit snugly into your Mini-ITX case and provide plenty of power for 1080p gaming with 8GB GDDR6 memory.
