The perception of gaming PCs as large, space-consuming towers is rapidly becoming outdated. Mini gaming PCs now offer formidable performance in compact chassis, some as small as a cable box, without sacrificing the ability to play modern games. These smaller form factors often involve trade-offs, particularly in accommodating high-end discrete graphics cards and extensive cooling solutions, meaning many models utilize powerful APUs or mobile-class GPUs instead of their desktop counterparts.
Manufacturers approach these space constraints differently. Asus, through its acquisition of Intel's NUC brand, produces small desktops utilizing mobile hardware. Others, like Zotac, manage to integrate powerful desktop-class components into very small cases, though these systems can be more difficult to service and upgrade and often come at a premium.
Asus ROG NUC
Asus's ROG NUC stands out for its exceptionally small size, comparable to a cable box, yet it is equipped with mobile-class hardware, including an Nvidia GeForce RTX 4070. This makes it a surprisingly capable machine for living room setups. While it can run demanding games like Cyberpunk 2077 and Black Myth: Wukong, achieving a solid framerate often requires settings adjustments, especially at 4K resolutions. For 1080p gaming, it performs admirably, and technologies like DLSS can help narrow the performance gap at higher resolutions. The trade-off for its compact design is the reliance on mobile-grade components, which are inherently limited compared to full desktop GPUs.
MinisForum X1-255
The Minisforum X1-255 offers a budget-friendly entry into the mini PC gaming space. Featuring an AMD Ryzen 7 255 CPU with an integrated RDNA 3 GPU, it provides solid performance for esports titles. This model is typically sold as a barebones system, requiring users to supply and install their own RAM and storage. While this necessitates some DIY effort, it can lead to cost savings. The integrated Radeon 890M GPU, when paired with fast memory and running off wall power, can offer enhanced performance, though users should still expect to moderate graphical settings for most modern games at 1080p.
Steam Machine
Valve's Steam Machine represents a significant step in integrating PC gaming into the living room. Its compact form factor, roughly one-third the size of a PS5, makes it unobtrusive. It features custom AMD hardware, including a Zen 4 CPU and an RDNA 3 GPU. While it delivers good gaming performance for its size, achieving 60 fps in all titles, including demanding ones like Death Stranding 2, may require careful tuning of in-game settings. Priced at $1,049, it is an expensive option for a mini PC, but it offers a compelling alternative for Steam library owners who wish to play on their TV without repurchasing games.
Corsair One i600
For users prioritizing graphical power in a small footprint, the Corsair One i600 offers desktop-class components, including an Nvidia GeForce RTX 5080 and an Intel Core Ultra 9 285K processor. Despite housing such high-performance hardware, its chassis remains relatively compact at 15 inches tall. This machine is designed for high-end 4K gaming, but this level of performance in a small form factor comes at a significant cost, with a price tag around $4,499. It represents a compromise where space is saved, but the price is considerably higher than building a similarly specced, larger desktop PC.
Mac mini M4
While not traditionally considered a gaming device, the Mac mini M4 with its M4 chip, featuring 10 CPU and 10 GPU cores, offers surprisingly capable gaming performance. It supports up to two 4K displays at 120Hz and benefits from Thunderbolt 4, allowing for potential external GPU upgrades. Although macOS gaming options are expanding, and its Metal API is improving, its game library and compatibility remain more limited than Windows PCs. For users invested in the Apple ecosystem, it provides a viable option for playing a range of titles at respectable frame rates.
Choosing the Right Mini PC
Selecting a mini PC for gaming hinges on the types of games to be played and the desired resolution. The limited internal space in these devices necessitates compromises, often impacting the GPU, CPU, or overall upgradability. For graphically intensive titles, a strong discrete GPU, such as an Nvidia RTX or AMD Radeon card, is preferable over integrated graphics. A capable CPU with at least four cores and high clock speeds, coupled with 16GB of RAM and a 512GB SSD, is recommended for smooth multitasking and game loading. Ensuring sufficient ports for peripherals and display outputs is also crucial, with Thunderbolt ports being a valuable addition for high-speed external devices.
