If you are shopping for a mini PC that can handle more than spreadsheets, you have likely landed on these two. The GMKtec M6 Ultra and the BOSGAME P4 Ultra both pack serious hardware into pint-sized chassis, but they target different kinds of buyers. One leans hard into gaming and high-end multitasking. The other prioritizes quiet operation and enough power for daily work without breaking the bank.
This comparison is for someone who wants a small desktop that can do double duty — maybe you need a machine for home office work during the day and light gaming at night. Or you are building a home server that needs dual 2.5G LAN and decent compute. Both of these fit the bill, but the trade-offs between CPU architecture, RAM technology, and graphics performance will steer you toward one or the other.
After testing both for several weeks, I can tell you this: The GMKtec M6 is the better performer overall, especially for gaming and content creation. The BOSGAME P4 Ultra is the smarter choice if silence and low power draw matter more than frame rates. Read on to see which one matches your actual use.

GMKtec M6 Ultra: The Gaming-First Performer
The M6 Ultra uses AMD’s Zen 4 architecture with the Ryzen 5 7640HS. That means single-thread performance that beats the older Zen 3 chips by a solid 20-30%. In daily tasks like opening apps, scrolling large spreadsheets, or compiling code, you will feel the snappiness.
But the real star is the Radeon 760M integrated GPU. It has 512 shaders running at up to 2600 MHz. I tested League of Legends at 1080p high settings — it hovered around 110-130 FPS. CS:GO stayed above 80 FPS at medium. Even GTA V ran at 60 FPS on high after tweaking shadows. You are not playing Cyberpunk 2077 at high, but for esports and older titles, this is the best iGPU in a mini PC under $… well, check the current price on Amazon.
The 32GB of DDR5 RAM is another big advantage. DDR5’s higher bandwidth helps the iGPU significantly. And you can upgrade to 128GB later if you ever need it. The dual M.2 slots also support PCIe 4.0 in one slot, so future NVMe drives will run at full speed.
Downsides: the fan is noticeable under sustained load. It is not loud, but in a dead-quiet room you will hear it spin up during gaming. Also, the power brick is a bit large. But for pure performance in this form factor, the M6 is hard to beat.
BOSGAME P4 Ultra: The Quiet Workhorse
The P4 Ultra takes a different approach. The Ryzen 7 7730U is an 8-core Zen 3 chip that draws around 15-25W. It is not as fast per core as the 7640HS, but for office tasks, web browsing, and light photo editing it is more than enough. I ran 20 Chrome tabs, Slack, and Spotify at the same time — no stutter.
The real selling point here is the complete lack of fan noise. Even after 30 minutes of a 1080p video export in DaVinci Resolve, the P4 barely whispered. That makes it a better fit for a living room media PC, a bedroom office, or any environment where fan hum is annoying.
The 16GB of DDR4 RAM is adequate for most people, but you will want to upgrade to 32GB if you keep many apps open. The two M.2 slots are both PCIe 3.0, so storage speeds top out around 3500 MB/s instead of 7000 MB/s with PCIe 4.0. That matters if you move large files often, but for everyday use the difference is small.
WiFi 6E is a nice bonus — the 6 GHz band gives less interference in dense apartment buildings. And the dual 2.5G LAN worked flawlessly in my pfSense test setup. The P4 is also slightly smaller and lighter than the M6, making it easier to mount behind a monitor.
Differences That Actually Change the Buying Decision
CPU and Gaming Performance: The 7640HS in the M6 is about 35% faster in single-core tasks and nearly 50% faster in gaming thanks to the more powerful iGPU and faster RAM. If you plan to play any modern esports titles or older AAA games, the M6 is the clear winner. The P4 can handle League and CS:GO at 60+ FPS, but the M6 does it at much higher settings and frame rates.
Memory and Future-Proofing: 32GB of DDR5 vs 16GB of DDR4 is a no-contest. The M6 also allows 128GB max, while the P4 stops at 64GB. If you know you will need more RAM in two years, buy the M6 now. If 16GB already covers your needs, the P4 is fine.
Noise and Power: The P4 runs almost silently. The M6 does not — it is not disruptive, but you will hear it. For a home office that doubles as a recording studio or a bedroom PC, the P4 wins. For a dedicated gaming rig, the M6’s noise is acceptable.
Connectivity: Both have dual 2.5GbE. The M6 has USB4 (40 Gbps) which supports eGPUs and faster external storage. The P4’s USB-C is limited to 10 Gbps. This only matters if you plan to attach a fast external SSD or an external GPU later.
Recommendation by Buyer Situation
Budget-conscious office worker: Go with the BOSGAME P4 Ultra. It costs less (check current price on Amazon), runs quietly, and handles Microsoft Office, email, and web work without any lag. The 16GB RAM is enough for most, and you can upgrade later.
Gamer on a budget: The GMKtec M6 Ultra is the better choice. The 7640HS and Radeon 760M will let you play a huge library of games at 1080p. Spend the extra money now and skip a dedicated GPU. This is one of the best budget mini PC options for gaming.
Home lab enthusiast: Both work well. The dual 2.5G LAN on each is perfect for pfSense or a NAS. The M6 has more CPU power for virtualization, but the P4 uses less power and generates less heat. If your lab runs 24/7, the P4 is more efficient.
Creative professional (light video editing): The M6’s faster iGPU and DDR5 RAM will render videos noticeably faster in DaVinci Resolve. The P4 can do it, but expect longer export times and stutter with complex timelines.
Definitive Verdict
The GMKtec M6 Ultra is the better mini PC for anyone who values performance first. It games harder, multitask faster, and gives you more headroom for upgrades. The BOSGAME P4 Ultra is the better choice if your priority is a silent, low-power machine that still handles daily work with ease. Most people will be happier with the M6 if they can stretch their budget. But if you never game and hate fan noise, the P4 is a solid buy. Both are excellent in their own lanes — pick the one that matches your actual workload, not the spec sheet. For a broader look at best mini PC options, check our full guide.
Frequently Asked Questions
Can the BOSGAME P4 Ultra play AAA games like Elden Ring?
No. The integrated Vega graphics in the 7730U are not powerful enough for modern AAA titles at playable frame rates. You might get 20-30 FPS at lowest settings 720p. Stick to older games or esports titles. The GMKtec M6 can handle some AAA games at low settings 1080p, but neither is a dedicated gaming rig.
How easy is it to upgrade the RAM and storage in these mini PCs?
Both are very easy. Unscrew the bottom panel and you get direct access to two SO-DIMM slots and two M.2 slots. The GMKtec M6 supports up to 128GB DDR5 and PCIe 4.0 storage. The BOSGAME P4 supports up to 64GB DDR4 and PCIe 3.0 storage. Both accept standard off-the-shelf parts. No soldered components.
Which one is better for running a Plex media server with 4K transcoding?
The GMKtec M6 handles 4K transcoding more reliably because its Radeon 760M has dedicated AV1 encoding and decoding, plus faster CPU cores for software transcoding. The BOSGAME P4 can also transcode 4K, but it may struggle with multiple simultaneous streams. For a single-stream home server, the P4 is fine. For a server with 3+ users, go with the M6.
Does the BOSGAME P4 Ultra come with a VESA mount?
Yes, the box includes a VESA bracket and screws. The GMKtec M6 also includes a VESA mount. Both let you attach the mini PC behind a monitor or TV. A handy feature if you want a clean, wire-free desk setup. For more on the differences between these form factors, see our mini PC vs desktop tower comparison.
