Two of my friends bought mini PCs for different reasons last year. One wanted a cheap, silent machine for spreadsheets and video calls. The other wanted something that could play games and handle heavy multitasking. They ended up with the KAMRUI AK1PLUS and the GMKtec M6 Ultra. After spending a weekend swapping desks and testing each other’s setups, we found real differences that matter more than the spec sheets suggest.
This comparison is for anyone who’s stuck between a basic budget box and a more powerful mini PC. If you mainly browse the web, write documents, and stream Netflix, the KAMRUI will do the job and save you money. If you want to edit photos, compile code, or play Fortnite at decent settings, the GMKtec is worth the jump. The gap in performance is larger than the price difference might indicate.
We’ll walk through each machine, compare the specs that actually affect daily use, and give you a clear verdict for your situation. No fluff. Just what we found after real use.

KAMRUI AK1PLUS: The Quiet Office Worker
The first thing you notice with the KAMRUI is how small and light it is. It sits on a desk without taking any real space. The fan is almost inaudible — even under load you barely hear it. My friend uses it for 8-hour shifts of Slack, Outlook, Google Docs, and the occasional Zoom call. It handles that stuff without stuttering.
The Celeron N5095 is not fast by modern standards. Opening a big Excel file takes a couple seconds. Browsing with 20 tabs slows it down eventually. But for single-task office work, it’s fine. The 16GB LPDDR4X RAM is soldered, so you can’t upgrade it later. That’s a limitation. Storage is more flexible: there’s an M.2 slot and a bay for a 2.5-inch drive, so you can add up to 4TB total.
Dual 4K@60Hz via HDMI works perfectly. My friend runs two 27-inch monitors side by side. Text is sharp, no flicker. The machine also supports Auto Power On and Wake-on-LAN, which makes it a decent choice for a kiosk or a simple home server. It’s not a gaming PC. Intel UHD Graphics can barely play games from ten years ago. But for its intended use — business, email, media consumption — it’s reliable and quiet.
GMKtec M6 Ultra: The Power House
The GMKtec M6 Ultra feels like a different class of machine. The Ryzen 5 7640HS is a beast compared to the Celeron. My other friend runs VirtualBox VMs, does light video editing in DaVinci Resolve, and plays games like Rocket League and GTA V at 1080p medium settings. The Radeon 760M graphics are surprisingly capable for an iGPU. You won’t play Cyberpunk at high settings, but esports titles and older AAA games run smoothly.
The 16GB DDR5 RAM is dual-channel and upgradable. That’s a big deal. If you need 32GB or 64GB later, you can swap the sticks. Storage is also more future-proof: a second M.2 slot supports PCIe 4.0 drives. The included 512GB NVMe boots Windows in seconds. The dual 2.5GbE LAN ports make this a great option for a home router or NAS setup. Wi-Fi 6E gives fast wireless speeds if your router supports it.
Triple display support is a killer feature. The USB4 port can drive an 8K monitor or a high-refresh 4K display. My friend uses two 1440p gaming monitors and a 4K TV for productivity. No lag, no fuss. The fan is louder than the KAMRUI when gaming, but it’s not annoying. Under normal office loads it stays quiet.
One caveat: the GMKtec draws more power. At 45–60W TDP, it’s not a 15W laptop chip. Electricity cost is tiny, but it runs warmer. The metal case gets warm to the touch during gaming. That’s expected.
Differences That Actually Change Your Buying Decision
Processing power for multitasking
The Celeron N5095 has four cores and four threads. The Ryzen 7640HS has six cores and twelve threads. In our real-world test, the GMKtec handled 30 browser tabs, Spotify, Slack, and a 4K video stream without breaking a sweat. The KAMRUI started stuttering at around 15 tabs plus a video. Clear call: if you juggle many applications at once, get the GMKtec.
Gaming and graphics
The Radeon 760M is roughly as fast as an Nvidia GTX 1050 Ti. It can run most modern games at 1080p low-medium. The Intel UHD Graphics in the KAMRUI can’t game at all — it’s strictly for video playback and basic UI. Clear call: if you play any games, the GMKtec is the only choice.
Upgradability
KAMRUI’s RAM is soldered. GMKtec uses SO-DIMM slots. Storage expansion is better on the GMKtec because of the second M.2 slot. Clear call: if you want to keep the PC for 3–4 years and upgrade later, pick the GMKtec.
Network features
Dual 2.5GbE LAN on the GMKtec is rare in mini PCs under $400. It’s perfect for router projects, file servers, or fast local transfers. The KAMRUI has one Gigabit port. Clear call: if you need a home lab or media server, the GMKtec wins.
Recommendation by Buyer Situation
Budget buyers (under $200): The KAMRUI AK1PLUS is the sensible pick. It’s cheap, quiet, and does office tasks well. Just know it won’t handle heavy loads or gaming. Check the current price on Amazon — it’s often the cheapest mini PC with 16GB RAM and a 256GB SSD. Consider what is a mini pc for your first build.
Mixed-use home office (+ some creative work): The GMKtec M6 Ultra is worth the extra money. You get real CPU and GPU power, upgrade options, and triple displays. It replaces a desktop tower easily. Read our best budget mini pc guide to see how it stacks against other models.
Enthusiasts and tinkerers: GMKtec without question. The dual 2.5GbE LAN, USB4, and upgradable RAM/SSD make it a flexible platform for Plex servers, retro gaming, or lightweight workstation use. If you’re switching from a full tower, check out our mini pc vs desktop tower article.
Verdict
The KAMRUI AK1PLUS is a good mini PC for its price. It does one thing quietly and well: basic productivity. The GMKtec M6 Ultra does everything better, but costs more. If I had to pick one for most people, it’s the GMKtec. The performance gap is too wide to ignore, and the upgradability means it won’t feel obsolete in two years. The KAMRUI is only a better choice if your absolute budget cannot flex, or if silence and low power draw are your top priorities.
