GEEKOM A6 Mini PC Review UK 2026

Right, so here's the thing about buying a prebuilt PC: most people don't actually want to spend a weekend sourcing components, watching compatibility videos, and hoping they haven't fried something during assembly. They want a machine that works, out of the box, without the faff. The GEEKOM A6 Mini PC sits squarely in that space. It's a compact, fanless-looking little box that promises AMD Ryzen AI performance in something roughly the size of a thick paperback novel. But does the budget-tier asking price actually reflect good value, or are you paying convenience tax on mediocre parts?

I've been using the GEEKOM A6 as my daily driver for several weeks now, running it through everything from spreadsheet marathons and video calls to light gaming sessions and 4K media playback. I've also cracked it open to see what's actually inside, because that's where prebuilt manufacturers tend to make their compromises. The short version: it's more interesting than I expected. The longer version is below.

This GEEKOM A6 Mini PC Review UK 2026 covers everything you need to know before handing over your money, including where GEEKOM spent wisely and where they cut corners to hit that price point.

Memory is 32GB of LPDDR5X running at 7500MHz in dual channel, soldered to the board. Storage is a 1TB M.2 NVMe SSD. There's no discrete GPU, no traditional PSU, and no tower chassis. Power comes via a 120W external adapter, which is compact and tidy but worth noting if you're thinking about upgrade headroom (spoiler: there isn't much). The whole unit runs Windows 11 Pro out of the box, which is a nice touch at this price tier rather than the Home edition you often see.

Build-wise, the chassis is aluminium alloy with a passive cooling fin design on the top and sides, supplemented by an internal fan that kicks in under load. It's genuinely small. I put it next to a standard external hard drive for scale and it's not much bigger. Connectivity is solid for the form factor, with Thunderbolt 4, USB4, multiple USB-A ports, HDMI 2.1, and Wi-Fi 6E. Full breakdown below.

For day-to-day work, it's genuinely fast. I had Chrome open with about 30 tabs (don't judge me), a Teams call running, Lightroom processing a batch of RAW files in the background, and the machine didn't flinch. That's partly the Zen 5 architecture being efficient, and partly the 32GB of fast LPDDR5X memory giving the system plenty of breathing room. If you're a content creator, a developer, or someone who just runs a lot of stuff at once, this handles it without complaint.

The NPU (Neural Processing Unit) built into the HX 370 is worth a mention too. It's rated at 50 TOPS, which qualifies it as a Copilot+ PC under Microsoft's AI requirements. Practically speaking, that means things like Windows Studio Effects for webcam backgrounds and AI-assisted features in supported apps run on the NPU rather than hammering the CPU or GPU. Whether you care about that depends on your workflow, but it's there and it does work. I tested it with a few AI upscaling tasks and the offloading was noticeable in terms of keeping the rest of the system responsive.

More demanding modern titles need some compromise. Baldur's Gate 3 ran at around 40-50fps on medium 1080p, which is playable but not silky. Shadow of the Tomb Raider at 1080p low settings averaged around 55fps. The 890M has 16 compute units and benefits massively from the fast LPDDR5X memory bandwidth, which is why it outperforms older integrated solutions by a meaningful margin. AMD's FSR 3 upscaling also helps in supported titles, and there are quite a few of those now.

For 4K, forget gaming. But 4K media playback is flawless. I ran Netflix, YouTube 4K HDR, and local HEVC files without any issues. The HDMI 2.1 outputs support 4K at 120Hz, which is useful if you're using this as a living room media machine or a secondary desktop. Ray tracing is technically supported but practically unusable at any meaningful resolution. This is a light gaming machine, not a gaming rig. If you go in with that expectation, you won't be disappointed.

The 1TB NVMe SSD is a PCIe 4.0 drive, and sequential read speeds in our testing came in around 5,000MB/s, which is proper fast. Boot times are under 15 seconds from cold. Application launches are near-instant. Day to day, storage is not a bottleneck here at all. The SSD is user-replaceable, which is good news. There's one M.2 2280 slot inside, and swapping it out is straightforward if you need more space down the line.

There's also a second M.2 slot inside the unit, which is a nice surprise for a machine this compact. In our testing unit it was empty, so you can add a second NVMe drive without removing the existing one. That gives you a reasonable upgrade path for storage at least, even if the RAM situation is locked in. Combined with the 2.5GbE ethernet port, you could also use this as a lightweight NAS or home server if that's your thing, and the storage expansion options make that more viable.

Thermal throttling is the real question. In our testing, I ran Cinebench R23 multi-core on a loop for 30 minutes to see if performance dropped off. The first run scored around 20,100 points. By the fifth run, it was sitting at around 19,400 points, a drop of about 3.5%. That's pretty good for a machine this size. The chip was running at around 95 degrees Celsius under that sustained load, which is within AMD's spec but does show the thermal headroom is limited. For burst workloads, it's fine. For sustained heavy compute tasks over hours, you might see some throttling.

The aluminium chassis genuinely helps here. It acts as a passive heatsink for the lower-power states, and the thermal design is better than some of the cheaper plastic mini PCs I've tested. GEEKOM has clearly put some thought into this rather than just bolting a tiny fan onto a hot chip and hoping for the best. Ambient temperature matters though. I tested in a room at around 21 degrees Celsius. If you're in a warmer environment or have it in an enclosed space, those temperatures will climb. Don't put it in a cabinet without ventilation.

Opening it up requires removing four screws from the bottom panel, which then slides off. Inside, the layout is tidy. The M.2 slots are accessible, the RAM is soldered (as mentioned), and the fan assembly is held in with a couple of screws if you ever need to clean it. Cable management isn't really applicable here given the form factor, but the internal routing of the antenna cables and power traces is neat. Nothing is rattling around loose, which sounds like a low bar but I've seen worse in machines costing significantly more.

The power button has a satisfying click to it, the status LED is a small, non-intrusive white dot, and the rubber feet on the bottom are chunky enough to actually grip a desk surface. These are small things, but they add up to an impression of a product that's been properly finished rather than rushed out. The only minor gripe is the external power brick, which is fairly large for a 120W adapter. It's not a dealbreaker, but it does add some desk clutter that a more integrated solution would avoid.

Wi-Fi 6E is the wireless standard here, using an Intel AX210 card. In our testing, I was getting around 1.8Gbps throughput on a Wi-Fi 6E router from about 5 metres away with one wall in between. That's fast enough that wireless versus wired is basically a non-issue for most tasks. Bluetooth 5.3 is also present and worked reliably with keyboards, mice, and headphones throughout testing. No dropouts, no pairing issues.

The dual HDMI 2.1 outputs plus the two USB4 ports mean you can technically drive three displays simultaneously, which is impressive for a machine this size. I tested dual 4K monitors at 60Hz and it handled it without any issues. The 2.5GbE ethernet is a nice touch over the more common 1GbE you see on budget machines, and it's useful if you're using this as a home server or connecting to a NAS. Overall, the connectivity story here is one of the stronger points of the A6.

Bloatware is minimal. There's a GEEKOM utility app pre-installed that handles fan curve settings and some basic system monitoring. It's actually useful rather than the usual collection of trial software and browser toolbars. McAfee was not present on our review unit, which is always a relief. There's a GEEKOM-branded wallpaper and that's about it. A clean Windows install would take maybe 20 minutes to set up if you wanted to start completely fresh, but honestly, there's not much to remove here.

The GEEKOM utility app is worth keeping, actually. It lets you switch between performance profiles (quiet, balanced, performance) which adjusts the fan curve and power limits. In performance mode, the chip gets more thermal headroom and runs faster under sustained loads. In quiet mode, it's near-silent but you'll see some throttling on heavy tasks. The balanced mode is where I left it for most of testing, and it's a sensible default. It's a simple app but it does what it needs to do without getting in the way.

Storage upgrades are actually pretty good though. There are two M.2 2280 slots, one of which is occupied by the included 1TB drive. The second slot is empty and accepts PCIe 4.0 NVMe drives. So you can add another 1TB, 2TB, or even 4TB NVMe without removing anything. That's a meaningful upgrade path for a machine this compact. There's no 2.5-inch SATA bay, so you're limited to M.2 form factors, but that's fine given how affordable NVMe drives have become.

There's no discrete GPU slot, no PCIe expansion, and the 120W external power adapter wouldn't support a discrete GPU even if there were. If you're thinking about adding a GPU later, this is not the machine for that. The Thunderbolt 4 ports do technically support external GPU enclosures (eGPUs), but that's an expensive and niche solution that I wouldn't recommend for most users. If gaming performance is a priority and you think you'll want to upgrade the GPU, a traditional tower prebuilt or a DIY build is a better starting point. The A6 is what it is, and it's good at what it is.

The Minisforum UM890 Pro is a close rival. It uses the Ryzen AI 9 HX 370 in some configurations, has a similar port layout, and is competitively priced. Where GEEKOM has an edge is build quality and the Windows 11 Pro inclusion. The Beelink SER9 is slightly cheaper in most configurations but uses older Ryzen 9 7940HS silicon, which means older integrated graphics and less AI capability. For pure productivity, the SER9 is still solid, but the 890M iGPU in the A6 is noticeably better for anything graphically demanding.

Against a DIY build, the comparison is more nuanced. You can't really build a mini PC yourself in the traditional sense, since the components are largely soldered or proprietary. The relevant comparison is whether you'd be better served by a small form factor tower build with a discrete GPU at a similar or slightly higher price. If gaming is a priority, yes, a budget tower build with a dedicated GPU will outperform the A6 for games. If compactness, silence, and productivity are the priorities, the A6 makes a strong case for itself.

The compromises are real though. Soldered RAM means you're locked at 32GB forever. No discrete GPU means gaming has a ceiling. The 120W power adapter is a bit chunky. And at the budget-tier price point, you're paying a small premium over some Chinese competitors for the GEEKOM name and slightly better build quality. Whether that premium is worth it depends on how much you value the fit and finish and the Windows Pro licence.

Who should buy this? Anyone who needs a fast, compact, quiet machine for office work, content creation, home server duties, or casual gaming, and who doesn't want a tower taking up desk space. It's also a solid choice for a living room PC or a secondary machine. Who should skip it? Anyone who wants to play demanding modern games at high settings, anyone who thinks they'll want to upgrade the RAM later, or anyone who needs a discrete GPU for GPU-accelerated workloads like machine learning or serious 3D rendering. For those use cases, a tower build makes more sense.

Our editorial score: 8 out of 10. Strong chip, good build, fair price for what you get. The soldered RAM and thermal ceiling under sustained loads are the only things stopping it from scoring higher.
