GMKtec EVO-X2 AI Mini PC Review: Ryzen AI Max+ 395 with 128GB Unified Memory

There's a specific kind of frustration that comes from buying the wrong mini PC. You spend weeks researching, pull the trigger on something that looks impressive on paper, and then spend the next year fighting thermal throttling, inadequate ports, or a GPU that can't keep up with what you actually need it to do. I've been through that cycle enough times to know that the buying decision here matters far more than most tech purchases, because the compromises are harder to live with when the machine is supposed to replace a full desktop.

The GMKtec EVO-X2 AI Mini PC is positioned as an answer to that problem. It's built around AMD's Ryzen AI Max+ 395, a chip that AMD designed specifically to blur the line between traditional CPU performance and discrete GPU capability inside a compact form factor. Pair that with 128GB of LPDDR5X memory running at 8000MHz, a 2TB PCIe 4.0 SSD, and support for quad 8K display output, and you've got a spec sheet that reads more like a workstation than a mini PC. I've been running this machine through its paces for several weeks now, across creative workloads, gaming sessions, and the kind of mundane daily use that reveals whether a machine is genuinely practical or just impressive in benchmarks.

The short version: this is a serious machine for serious users, and the price reflects that. But whether it's the right serious machine for your specific situation is a more nuanced question. Let me walk you through what I found.

The CPU side gives you 16 cores running up to 5.1GHz, which is competitive with mainstream desktop processors from a couple of years ago. The GPU side is where things get interesting: the Radeon 890M graphics inside the AI Max+ 395 has 40 compute units, which puts it in a different league from the integrated graphics you'd find in a standard mini PC. GMKtec has paired all of this with a 2TB SSD on a PCIe 4.0 interface, which delivers sequential read speeds that won't bottleneck the rest of the system. WiFi 7 and USB4 round out the connectivity story, and I'll get into both of those in more detail later.

One thing worth noting before we get to the specs table: the 128GB memory configuration is fixed. This isn't a machine where you can upgrade the RAM later, because the LPDDR5X is soldered directly to the board as part of the unified memory architecture. That's a trade-off you need to accept going in. For most users, 128GB is more than enough for the foreseeable future, but if you're the type who likes to upgrade incrementally, that's a limitation worth knowing about upfront.

The quad display output with 8K support is another feature that sounds like spec-sheet padding until you actually use it. I tested this with three monitors connected simultaneously (two via DisplayPort over USB4 and one via HDMI), and the EVO-X2 handled all three without any of the flickering or resolution compromises I've seen from lesser mini PCs trying to drive multiple screens. The 8K claim is technically accurate for single-display output, though in practice most users will be running multiple 4K screens rather than a single 8K panel, and that's where the machine genuinely earns its keep for creative professionals.

Wi-Fi 7 support is something I'm increasingly treating as a meaningful differentiator rather than a checkbox feature. The EVO-X2 supports the 6GHz band and multi-link operation, which in a real-world home office environment with a compatible router translated to noticeably more stable throughput than Wi-Fi 6E devices I've tested in the same location. The SD Card Reader 4.0 is a small but genuinely useful addition for photographers and videographers, offering transfer speeds that won't have you waiting around when offloading large RAW files or high-bitrate video footage. And the NPU, rated at 50 TOPS, positions this machine to handle Microsoft's Copilot+ requirements and local AI inference tasks without leaning on the CPU or GPU.

Gaming performance is where the unified memory architecture really shows its value. I tested a range of titles at 1080p and 1440p, and the Radeon 890M handled modern games at medium-to-high settings with playable frame rates in a way that no previous integrated graphics solution has managed in my testing. Cyberpunk 2077 at 1080p with medium settings averaged around 45 to 55 fps, which isn't going to satisfy a dedicated gaming PC owner but is genuinely impressive for a machine this size with no discrete GPU. Older and less demanding titles ran at high settings without complaint. The machine does get warm under sustained gaming load, and the fan noise increases noticeably, but it never throttled in a way that caused performance to drop mid-session.

For creative workloads, the story is similarly positive. Video editing in DaVinci Resolve with 4K footage was smooth, with the GPU acceleration making a real difference to render times. I ran a local large language model using Ollama (a 13B parameter model), and the 128GB unified memory meant it loaded and ran without the memory errors you'd get on a machine with conventional integrated graphics and limited VRAM. Photo editing in Lightroom with large RAW files from a 45-megapixel camera was responsive. The SSD speeds are genuinely fast, and you feel that in application load times and file operations. Where the machine shows its limits is in sustained heavy workloads over long periods: the thermal solution is doing a lot of work, and in a warm room, you'll hear the fan working harder than you might expect from a machine marketed partly on its compact, quiet-desktop appeal.

The port layout is well thought out. Front-facing ports include USB-A and the SD card reader, which makes sense for devices you connect and disconnect regularly. The rear panel carries the heavier-duty connectivity: USB4, additional USB 3.2 ports, HDMI, and the power input. The ventilation design uses a bottom intake and rear exhaust configuration, which works reasonably well in practice but does mean you need to be careful about surface placement. Putting this on a thick carpet or a surface that blocks the bottom vents will cause thermal issues. I'd recommend the included stand or a hard, flat surface.

One area where I'd push back slightly on the build is the power brick. The external power supply is large and heavy, which feels at odds with the compact machine it's feeding. This is a common compromise in high-performance mini PCs (the power delivery requirements of a chip like the AI Max+ 395 demand a substantial PSU), but it does undermine the clean desk aesthetic somewhat. The cable management situation around the back of the machine can get cluttered quickly if you're running multiple displays and peripherals. That's not a dealbreaker, but it's worth factoring into your desk setup planning. Overall, though, this feels like a machine built to last rather than one cutting corners to hit a price point.

Connecting multiple displays took a few minutes to sort out the first time, mainly because the USB4 ports require DisplayPort Alt Mode cables rather than standard USB-C cables, and the documentation could be clearer about this. Once I had the right cables, the quad-display setup worked without any driver fiddling. The machine recognised all three of my test monitors immediately and allowed independent resolution and refresh rate settings for each. For anyone coming from a traditional desktop, the transition to a mini PC workflow is minimal here: it behaves like a proper desktop computer, just smaller.

Day-to-day operation is quiet enough for an office environment when you're doing light work. Web browsing, document editing, video calls: the fan is barely audible. Push it with a render job or a gaming session and the fan profile ramps up, which is the correct behaviour but worth knowing if you're planning to use this in a noise-sensitive environment. The machine wakes from sleep reliably (something that's been a persistent issue with some AMD-based mini PCs in the past), and I didn't experience any of the USB device disconnection issues on wake that have affected other machines I've tested. The SD card reader is fast and recognised every card I tested immediately, which sounds basic but isn't always the case with cheaper readers.

Wi-Fi 7 support is genuinely useful if you have a compatible router, and the 6GHz band performance in my testing was excellent. If you're still on a Wi-Fi 5 or Wi-Fi 6 router, you won't see the full benefit, but the card is backward compatible and will perform well on older standards. Bluetooth 5.4 handled all my peripherals without pairing issues. The 2.5GbE wired Ethernet port (confirmed via the rear I/O) is a welcome addition for anyone who prefers a wired connection for stability, and it's fast enough to saturate most home broadband connections without breaking a sweat.

Compatibility with external hardware was broadly excellent. I tested with a range of USB-C and USB-A peripherals, multiple monitor brands and models, and a variety of SD cards including UHS-II cards that the SD 4.0 reader is designed to support. Everything worked. The one compatibility note I'd flag is around eGPU enclosures: while the USB4 port supports external GPU connections in theory, the performance benefit is limited because the AI Max+ 395's integrated GPU is already more capable than what most eGPU setups would add. You'd be better off spending that money elsewhere. For software compatibility, Windows 11 Pro means you're running a fully supported OS with access to the complete Windows application ecosystem, and AMD's driver support for the AI Max+ 395 has been solid in my experience over the testing period.

The second strong use case is local AI work. If you're running large language models, image generation models, or other AI inference tasks locally (rather than relying on cloud APIs), the 128GB unified memory pool is a significant advantage. Models that won't fit in the VRAM of a conventional discrete GPU will run on this machine. I ran Llama 3 70B quantised to 4-bit, and it loaded and ran inference at a usable speed. That's not something you can do on most mini PCs or even most laptops. For developers and researchers who want to experiment with local AI without cloud costs, this is a genuinely compelling option.

Gaming is a legitimate use case, but with realistic expectations. This isn't a replacement for a dedicated gaming PC if you want to play the latest titles at maximum settings and high frame rates. But if you want a machine that can handle a broad library of games at reasonable settings, including some modern titles at 1080p, while also being a proper productivity workstation, the EVO-X2 covers that ground better than anything else in the mini PC category I've tested. It's particularly good for older or less demanding games, indie titles, and anything from the last generation that doesn't require cutting-edge GPU performance. Think of it as a capable gaming machine that also happens to be an excellent workstation, rather than a gaming PC first.

Home server and media centre use is another angle worth considering. The machine is compact enough to sit unobtrusively in a living room or media cabinet, quiet enough under light load for that environment, and powerful enough to handle Plex transcoding, home automation software, and local NAS duties simultaneously. The 2TB SSD gives you reasonable local storage, and the USB4 port means you can attach fast external storage if you need more. It's probably overkill for pure media centre use, but if you want a single machine that handles media, light gaming, and occasional productivity work, it makes sense.

The value question depends entirely on what you'd be replacing or comparing it to. If you're looking at this versus a traditional desktop workstation with a discrete GPU, the EVO-X2 is competitive on price when you factor in the cost of a case, CPU, motherboard, RAM, SSD, and GPU separately. A desktop with comparable CPU performance, 128GB of RAM, a 2TB NVMe SSD, and a mid-range discrete GPU would cost a similar amount or more, and it would take up significantly more space. From that angle, the EVO-X2 represents reasonable value for what it delivers. If you're comparing it to a standard mini PC in the budget-to-mid-range category, the price gap is enormous, and you need to honestly assess whether the additional capability justifies the spend for your specific workloads.

I wouldn't recommend waiting for a sale if you need this machine now and the use case fits. The AI Max+ 395 is a new platform, and pricing tends to be sticky on new silicon. What I would say is that if your workloads don't specifically benefit from the unified memory architecture or the GPU capability, there are more affordable mini PCs that will handle everyday computing tasks perfectly well. The EVO-X2 earns its price for the right user. For everyone else, it's spending money on headroom you'll never use.

The Mac Mini with M4 Pro is the more interesting comparison. Apple's silicon is genuinely excellent, and the M4 Pro's efficiency and performance per watt are hard to argue with. But the Mac Mini tops out at 64GB of unified memory in its current configuration, which is half what the EVO-X2 offers. If you're running large AI models or working with memory-intensive professional applications, that gap matters. The Mac Mini also runs macOS, which is either an advantage or a limitation depending on your software requirements. If you're in a Windows-only workflow or need Windows-specific software, the choice is straightforward. If you're flexible on OS, the Mac Mini is a serious alternative worth evaluating.

The Intel-based competition is less compelling at this price point. Intel's integrated graphics, even with Arc, doesn't match the Radeon 890M's GPU performance, and the unified memory approach AMD uses gives the EVO-X2 a structural advantage for GPU-intensive workloads. Where Intel mini PCs have historically had an edge is in Thunderbolt support and certain professional application compatibility, but USB4 on the EVO-X2 covers most of that ground adequately.

The complaints are also consistent and worth taking seriously. Thermal management under sustained load is the most common concern, with some users reporting that the machine gets hot and the fan becomes intrusive during extended heavy workloads. A few reviewers mention the power brick size as a frustration, which I noted myself. There are also a handful of comments about the documentation being thin, particularly around display cable requirements and BIOS settings. None of these are dealbreakers, but they're genuine friction points that GMKtec could address with better documentation and a revised thermal solution in future iterations.

One pattern I noticed in the negative reviews: several of the lower ratings seem to come from users who bought this expecting desktop gaming PC performance and were disappointed. That's a mismatch of expectations rather than a product failure. The EVO-X2 is impressive for a mini PC with integrated graphics, but it's not competing with a machine that has a dedicated RTX 4080. If you go in with accurate expectations about what integrated graphics can deliver, even very capable integrated graphics, you're likely to be satisfied. If you're expecting discrete GPU performance in a mini PC chassis, you'll be disappointed regardless of which mini PC you buy.

For the enthusiast buyer who wants the most capable mini PC available and has the budget to match, this is currently the top of the stack. The Ryzen AI Max+ 395 platform is the most capable silicon available in this form factor right now, and GMKtec's implementation is solid. You're paying a flagship premium for flagship capability, and that's a legitimate transaction if the capability matches your needs. The 4.1-star rating with 52 reviews suggests most buyers who understood what they were buying are satisfied.

For the buyer who's attracted by the impressive spec sheet but whose actual workloads are primarily web browsing, document editing, and occasional video streaming: this is significant overkill, and there are mini PCs at a fraction of the price that will serve those needs perfectly well. The EVO-X2 earns its price tier for specific use cases. Outside those use cases, you're paying for headroom you'll never use. Be honest with yourself about which category you fall into before committing at this price level.

But "most capable" and "right for you" are different questions. The thermal solution works but isn't silent under load. The power brick is large. The documentation could be better. And the price is firmly in flagship territory, which means you need to be confident that the specific capabilities this machine offers are capabilities you'll actually use. If you're a video editor, a local AI developer, a multi-monitor power user, or someone who needs workstation-class performance in a compact form factor, the EVO-X2 is a serious option that deserves serious consideration. If you're a general user attracted by impressive numbers, look at something more appropriately priced for your actual needs.

I'd score this at 8.5 out of 10. The half-point deductions come from the thermal noise under sustained load, the large external power supply, and the thin documentation. Everything else, the performance, the connectivity, the build quality, the memory capacity, the display output, is genuinely impressive for the form factor. This is a proper workstation in a small box, and for the right user, it's worth every penny of the premium price.
