The ACEMAGIC K1 is a palm-sized mini PC built around AMD’s Ryzen 7 7730U: eight cores, sixteen threads, 16GB of RAM and a 1TB SSD, with Windows 11 Pro already installed. It is aimed at people who want one small, quiet box for work, 4K video and esports games, without the size or the noise of a tower. On Amazon it has a 4.4-star rating from more than 400 buyers and sits in the top 15 of the Mini Computers category.

This review is based on ACEMAGIC’s published specifications, the Amazon listing as of October 10, 2026, the chip’s specifications from AMD and the hands-on video reviews embedded below. We have not run our own benchmarks on this unit.

Design: a 5-inch box that hides behind a monitor

ACEMAGIC K1 front and rear ports

The K1 measures 5.04 × 5.04 × 1.61 inches, about the footprint of a coaster, in a silver finish. The front has a USB-C port, two USB-A ports and a 3.5mm audio jack; the back has two more USB-A ports, Ethernet, DisplayPort, HDMI and the power input. Amazon counts six USB ports in total. Cooling is a single high-speed fan with a dual exhaust, and ACEMAGIC rates the whole system at about 45 W from the wall.

Performance: a real 8-core desktop

ACEMAGIC's Cinebench R23 results for the Ryzen 7 7730U

The Ryzen 7 7730U is a Zen 3 chip made on TSMC’s 7nm process, with 8 cores and 16 threads that boost to 4.5 GHz within a 15 to 28 W power range. ACEMAGIC’s own Cinebench R23 chart puts it at 10,801 points multi-core and 1,448 single-core, ahead of the Ryzen 7 5825U (9,772) and the Ryzen 7 5700U (8,154). Those are the brand’s numbers, but they are in line with what this chip scores in other mini PCs.

In practice that is plenty for office suites, dozens of browser tabs, video calls, photo editing and light video editing. It is a full desktop-class processor, far ahead of the Intel N95 and N100 chips found in most mini PCs at the low end of the market (such as the AceMagic S1 and the Geekom Air12).

Gaming: what Radeon Vega 8 can and cannot do

The graphics are AMD’s Radeon Vega 8: 8 compute units at 2000 MHz, sharing the system memory. It is an older integrated GPU, and it is worth being precise about it:

  • Good for esports. Games such as League of Legends, Valorant, Counter-Strike 2, Dota 2 and Rocket League run at 1080p with low settings. ACEMAGIC also lists Apex, PUBG, Rust and GTA V.
  • Older and lighter AAA games are playable at 720p or 1080p with low settings.
  • Recent AAA games are a stretch. Vega 8 is well behind AMD’s newer Radeon 680M and 780M graphics; if modern AAA games are the goal, look at the alternatives below.
  • Cloud gaming and streaming (Xbox Cloud, GeForce Now) work very well, because the K1 only decodes video, and its Wi-Fi 6 and wired Ethernet keep latency low.

ACEMAGIC notes that the dual-channel memory helps graphics performance, which is true: integrated graphics live and die by memory bandwidth.

Three 4K screens and a media center

ACEMAGIC K1 driving three 4K displays

The K1 drives three 4K displays at 60Hz at once, over HDMI 2.0, DisplayPort 1.4 and USB-C. That makes it a strong small desk PC for traders, remote workers and anyone who spreads work across screens. The same video engine handles 4K streaming and local 4K playback, so it also works as a living-room media center or a Plex box.

Memory, storage and connectivity

Inside the ACEMAGIC K1: LPDDR4X memory and M.2 SSD

  • Memory: 16GB of LPDDR4X-3733, soldered to the board. ACEMAGIC states that it cannot be expanded, so 16GB is what you will have for the life of the machine. For Windows, office work and gaming that is enough; for virtual machines or local AI models it is not.
  • Storage: a 1TB M.2 2280 NVMe SSD, replaceable with drives of up to 4TB.
  • Wireless: Wi-Fi 6 and Bluetooth 5.2, plus wired Ethernet.
  • Software: Windows 11 Pro pre-installed; ACEMAGIC says Windows 10, Linux and Ubuntu also run on it.
  • Warranty: one year, with 24/7 technical support according to the listing.

What to keep in mind

  • Check the configuration and the price on the listing. The K1 page on Amazon groups many versions, from Intel N95 to Ryzen and Intel HX models, with different prices and colors. This review covers the silver Ryzen 7 7730U with 16GB and 1TB, listed at $669 on October 10, 2026. Make sure that is the option selected before you check out, and compare it with the other 7730U options on the same page, whose prices can differ.
  • The RAM cannot be upgraded. Buy it knowing 16GB is final.

ACEMAGIC K1 verdict

The ACEMAGIC K1 is a well-rounded small PC: a real 8-core processor, a fast 1TB SSD, three 4K outputs, Wi-Fi 6 and Windows 11 Pro in a box that fits in one hand. It is a good fit for esports and cloud gaming, a three-screen work desk, a student PC or a living-room media center. It is not a machine for current AAA games or for local AI, and its 16GB of memory is fixed.
