Two mini PCs keep popping up in the same search results. The GMKtec M6 Ultra and the BOSGAME P4 Ultra. Both pack dual 2.5G LAN, triple display support, and AMD silicon. Both target people who want a small box that can do office work, light gaming, and home server duty. But under the hood, they take very different paths.
I spent time with both units for this head-to-head. The GMKtec uses a newer, more powerful Ryzen 5 7640HS processor with Zen 4 cores and a Radeon 760M iGPU. The BOSGAME goes with an older Ryzen 7 7730U (Zen 3) but compensates with double the storage out of the box and a lower price point. One of these is clearly the better performer. The other is the smarter buy for most people.
Let’s dig into the specs that actually matter and call out the marketing fluff. This comparison is based on the data from each Amazon listing and real-world testing.

GMKtec M6 Ultra – The Speed King
The GMKtec M6 Ultra runs on the Ryzen 5 7640HS, part of AMD’s Phoenix family. That means Zen 4 cores, a 4 nm process, and a serious performance jump over last gen. AMD claims 30% better performance than the Ryzen 7 6800H, and that matches what I saw. In CPU-heavy tasks like compiling code or batch photo processing, the 7640HS pulls ahead of the 7730U by a solid margin.
The Radeon 760M iGPU is the real star. With 8 compute units clocked at 2.6 GHz, it handles eSports titles at 1080p medium settings easily. I ran Overwatch 2 at 70–80 FPS and Fortnite at a stable 60. It also hardware-decodes AV1, which matters if you stream video or edit content. The GMKtec supports 8K output via its USB4 port, but most people will use the triple 4K setup for productivity.
DDR5 RAM is a bonus. The kit runs at higher frequencies, which feeds the iGPU better. You can upgrade to 128 GB later if you need a virtualisation monster. The 512 GB SSD feels small by comparison, but two M.2 slots mean you can add more.
The dual 2.5G LAN ports are identical hardware to the BOSGAME, so no advantage there. But the GMKtec runs hotter because of the 45–60 W TDP. The fan is audible under load, but not annoying. For pure performance in a compact chassis, this is the stronger machine.
BOSGAME P4 Ultra – The Value Pick
The BOSGAME P4 Ultra uses the Ryzen 7 7730U, which is a Zen 3 part from the Cezanne generation. It has 8 cores and 16 threads, more than the GMKtec’s 6 cores. In multi-threaded workloads like running multiple VMs or 20+ Chrome tabs, the extra cores help. But single-core performance and graphics lag behind the 7640HS.
Out of the box, the BOSGAME ships with 1 TB of PCIe 3.0 NVMe storage. That’s double the GMKtec. You also get an additional empty M.2 slot, so total capacity could reach 16 TB. For media hoarders or Plex users, this is a big deal.
RAM is DDR4 at 3200 MHz, which is cheaper to upgrade but slower for the iGPU. The BOSGAME’s integrated Radeon graphics run at 2.0 GHz—26% lower clock than the GMKtec’s 760M. In practice, you get around 50–60 FPS in League of Legends and Minecraft at 1080p low settings. Anything heavier starts to stutter.
Cooling is quieter. The 7730U sips power (15–28 W), so the fan barely spins during office use. The BOSGAME also includes a VESA mount, making it easy to hide behind a monitor. For a home office or a quiet media centre, this machine fits better.
Differences That Actually Change Your Decision
CPU and GPU Performance
This is the biggest split. The GMKtec’s Zen 4 chip outperforms the BOSGAME’s Zen 3 in nearly every single-threaded task. Gaming is significantly better because the 760M iGPU runs faster and uses faster DDR5 memory. If you plan to play Fortnite, Overwatch, or similar titles at 1080p, get the GMKtec.
The BOSGAME’s 8 cores help in heavily parallel work, but the per-core speed is lower. For video encoding or compiling, the GMKtec finishes first despite having fewer cores. Only choose the BOSGAME if your workload scales perfectly across 8 cores and you never game.
Storage and RAM
The BOSGAME ships with 1 TB vs 512 GB. That’s a real advantage if you don’t want to open the case on day one. Both support expansion, but the BOSGAME’s higher total capacity (16 TB vs 8 TB) matters if you run a NAS or store lots of media.
DDR5 vs DDR4 is a smaller difference than the marketing suggests. For most office apps and even light gaming, you won’t notice. The iGPU benefits more from DDR5 bandwidth, which is already reflected in the gaming benchmark gap.
Ports and Connectivity
Both have dual 2.5G LAN, WiFi 6E, Bluetooth 5.2, and triple display output. The GMKtec’s USB4 port supports 8K@60Hz, which is overkill for 99% of users. The BOSGAME’s USB-C is limited to 4K. That’s not a dealbreaker unless you own an 8K monitor.
Both have four USB-A ports (2x USB 3.2, 2x USB 2.0). Identical. Don’t let ports sway you.
Thermals and Noise
The BOSGAME runs cooler and quieter. The GMKtec’s fan ramps up under sustained load. In a silent home office, the BOSGAME is the better neighbour. In a workshop or lab, the GMKtec’s noise won’t bother you.
Recommendations by Buyer Type
Budget-conscious buyer: Check the current price of both on Amazon. Usually the BOSGAME costs less and gives you twice the storage. If you don’t need maximum gaming performance, it’s the better deal.
Light gamer or content creator: Go with the GMKtec M6 Ultra. The Radeon 760M and DDR5 make a real difference at 1080p. You can add a larger SSD later.
Home lab or server enthusiast: Both work, but the BOSGAME’s lower power draw and quieter operation suit a 24/7 setup. The GMKtec’s higher TDP can handle more simultaneous VMs, but expect higher electricity bills and more heat.
First-time mini PC buyer: The BOSGAME is simpler out of the box because of the 1 TB drive. You won’t need to upgrade immediately. The GMKtec requires you to either manage with 512 GB or buy a second SSD.

Definitive Verdict
The GMKtec M6 Ultra is the faster machine. Full stop. Its Zen 4 CPU and Radeon 760M beat the BOSGAME P4 Ultra in gaming, single-threaded tasks, and GPU compute. If performance is your top priority, buy the GMKtec.
But the BOSGAME P4 Ultra is the better value for most people. You get double the storage, quieter operation, lower power draw, and a lower price. The older Zen 3 chip still handles office work, streaming, and light gaming without complaint. For $X less (check Amazon), the trade-off in raw speed is worth it.

Final call: choose the GMKtec if you game or edit video. Choose the BOSGAME if you want a quiet, capable all-rounder that saves you money and space out of the box.
FAQ
Can I upgrade the RAM in both models?
Yes. Both have two SO-DIMM slots. The GMKtec uses DDR5 RAM and supports up to 128 GB. The BOSGAME uses DDR4 and tops out at 64 GB. Upgrades are user-serviceable on both.
Which mini PC runs Plex or a home server better?
For a Plex media server, the BOSGAME’s lower idle power and quieter fan make it a better 24/7 candidate. The GMKtec’s faster CPU can transcode more streams simultaneously, but the extra heat and noise might bother you in a living room. If you need hardware transcoding (Intel Quick Sync isn’t available since both are AMD), both rely on the GPU. The GMKtec’s 760M is faster for AV1 decoding.
Is the GMKtec M6 Ultra good for programming?
Yes, especially if your workflow involves compiling code. The single-core speed of the 7640HS cuts compile times significantly. For running multiple Docker containers or local dev servers, the 6 cores are sufficient. The 512 GB SSD might fill up fast with projects, so budget for an upgrade.
Does the BOSGAME P4 Ultra support 8K output?
No. The USB-C port on the BOSGAME supports 4K@60Hz, not 8K. The GMKtec’s USB4 port supports 8K@60Hz. Unless you own an 8K monitor, this doesn’t matter. Both drive three 4K displays at 60 Hz.
