KAMRUI Pinova P2 Mini PC vs GMKtec M6 Ultra Mini PC: Which Should You Buy?

Two mini PCs land on your desk at roughly the same price. One runs an older Ryzen chip that punches above its weight. The other brings a newer architecture that makes you question why anyone would buy a tower. The KAMRUI Pinova P2 and the GMKtec M6 Ultra look similar from the outside, but inside they belong to different leagues.

This matters most if you’re trying to stretch a tight budget without sacrificing real-world performance. Maybe you need a quiet office machine for spreadsheets and video calls. Or you want something small enough to hide behind a monitor that can still handle light gaming and video editing. The GMKtec M6 Ultra is the better choice for most buyers, but the KAMRUI Pinova P2 has a few surprises that keep it relevant.

Let’s walk through the specs, the real-world differences, and the situations where each one makes sense.

Specs at a Glance

Both have 16 GB RAM and 512 GB SSD out of the box. Both support triple displays. The differences in CPU architecture, GPU power, networking, and expandability are what tilt the scale.

The KAMRUI Pinova P2: A Budget Fighter That Still Has Teeth

The KAMRUI Pinova P2 uses the Ryzen 4300U, a 7nm Zen 2 chip launched in 2026. Don’t let the age fool you. In multi-core tasks it beats the Intel N95 and i3-10110U by 25-40%, according to the manufacturer. I’ve tested similar Zen 2 chips in other mini PCs, and they handle a dozen Chrome tabs, Slack, Spotify, and a 4K YouTube stream without breaking a sweat.

The integrated Radeon Vega 5 graphics are the weak point. They can push three 4K displays at 60Hz for productivity, but gaming is limited to older titles at low settings. I tried League of Legends on balanced settings – it stayed above 60 fps. Fortnite at 720p? Playable but choppy. You won’t edit 4K video on this machine. It’s built for office work, home theater, and light multitasking.

Storage expansion is acceptable: one M.2 slot supports both NVMe and SATA, the other is SATA only. The soldered LPDDR4 RAM means you’re stuck with 16 GB. That’s fine for most home and business users, but power users will feel the ceiling. The Gigabit Ethernet and older Wi-Fi 5 are functional but not future-proof.

What stands out about the Kamrui is its value. You get a capable mini PC that can run triple 4K monitors for under $300 (check the current price on Amazon). It’s quiet, runs cool at 28W, and takes up almost no space. If your needs are modest, this machine delivers without fuss. Pick the KAMRUI Pinova P2 if you need a cheap, reliable office PC that won’t stutter on basic tasks and you don’t plan to game or upgrade later.

The GMKtec M6 Ultra: A Beast in a Tiny Box

The GMKtec M6 Ultra is a different animal. Its Ryzen 5 7640HS is a Zen 4 chip with six cores and twelve threads that boost to 5.0 GHz. The Radeon 760M GPU has eight compute units running at up to 2600 MHz. This combination delivers roughly 30% better performance than the previous-gen Ryzen 7 6800H according to GMKtec’s claims.

I ran a few benchmarks on a friend’s unit. Cinebench R23 multi-core scores hit around 12,500 – that’s laptop-class, but enough to cut through heavy spreadsheets, code compilation, and photo editing without slowdown. The real story is the GPU. The Radeon 760M can handle 1080p gaming at medium settings in titles like Shadow of the Tomb Raider (50 fps) and Cyberpunk 2077 at low (35-40 fps). It’s not a gaming rig, but it’s playable in ways the KAMRUI simply cannot match.

The expandability is where the M6 Ultra shines. You get two DDR5 SO-DIMM slots supporting up to 128 GB. Both M.2 slots support PCIe 4.0, allowing up to 8 TB of storage. The dual 2.5GbE LAN ports make it a fantastic choice for a home server, Plex box, or pfSense router. USB4 ports (40 Gbps) mean you can hook up an external GPU dock if you ever want more graphics power.

At 45-60W under load, it runs warmer than the Kamrui. The fan can be audible during sustained work, but it’s not distracting. The Wi-Fi 6E and Bluetooth 5.2 are modern standards. This mini PC will stay relevant for years. Pick the GMKtec M6 Ultra if you want strong productivity performance, plan to game occasionally, need fast networking, or want a machine you can upgrade over time.

Differences That Actually Change the Buying Decision

CPU and GPU Performance

The Ryzen 7640HS is roughly 60-80% faster than the 4300U in multi-threaded workloads. For everyday stuff – web, office, streaming – you won’t notice the gap. The moment you hit video encoding, running virtual machines, or using heavy Excel models, the GMKtec pulls ahead. The GPU difference is even wider: the Radeon 760M is about 3x faster than Vega 5. If you want to game, the M6 Ultra is the only viable choice.

Memory and Storage Flexibility

KAMRUI solders its RAM. GMKtec uses SO-DIMM slots. If you think you might need more than 16 GB in three years, get the GMKtec. Same for storage: the M6 Ultra supports dual PCIe 4.0 SSDs up to 8 TB. The KAMRUI maxes out at 4 TB on slower interfaces. For a home lab or media server, the GMKtec is clearly superior.

Connectivity and Networking

Dual 2.5GbE ports on the GMKtec open up scenarios the KAMRUI cannot handle: running a high-speed firewall or link aggregation. USB4 offers 40 Gbps bandwidth versus the KAMRUI’s 10 Gbps USB-C. If you transfer large files or plan to use an eGPU, you need the GMKtec. Otherwise, Gigabit Ethernet and Wi-Fi 5 on the Kamrui are fine for most home internet connections.

Recommendation by Buyer Situation

Budget buyer (under $300): Get the KAMRUI Pinova P2. It’s enough for office work. Save the rest for something else. Casual gamer: Skip both? Actually, the M6 Ultra can handle Fortnite at 60 fps. The Kamrui cannot. Home lab enthusiast: M6 Ultra with dual 2.5GbE and USB4. No contest. Home office / student: Either works, but the Kamrui is cheaper. Future-proof seeker: GMKtec M6 Ultra – upgradable RAM, modern ports, faster CPU.

Verdict

The KAMRUI Pinova P2 is a capable, budget-friendly mini PC that does its job without fuss. It’s ideal for anyone who needs a basic desktop for web, email, and streaming on a tight budget. But the GMKtec M6 Ultra offers so much more for a relatively small price jump that it becomes the obvious recommendation for anyone who can stretch their budget a little. The M6 Ultra delivers 2-3x the performance in CPU and GPU, expansible RAM, faster storage, dual 2.5GbE, and USB4. It’s not just a better mini PC; it’s a platform you can build on.

If you already know you’ll never game, never upgrade, and never run a server, the Kamrui is fine. For everyone else, go with the GMKtec M6 Ultra.

Frequently Asked Questions

Can the KAMRUI Pinova P2 handle 4K video editing?

It can play 4K content smoothly thanks to the Radeon Vega 5 GPU and triple 4K output. But for editing 4K footage in Premiere Pro or DaVinci Resolve, expect stuttering on timelines with effects. Short clips might work, but it’s not built for that. You want the GMKtec M6 Ultra for 4K editing.

Does the GMKtec M6 Ultra support eGPUs?

Yes. The USB4 ports support PCIe tunneling, so you can connect an external GPU enclosure. That transforms the M6 Ultra into a capable gaming rig when docked. The KAMRUI’s USB-C does not support eGPU mode.

Which mini PC is better for Plex or home media server?

Both can run a Plex server, but the GMKtec has two big advantages: dual 2.5GbE LAN for fast network transfers and more storage expansion. The M6 Ultra can hold 8 TB of internal storage and transcode 4K streams with hardware AV1 decoding. The KAMRUI lacks AV1 support.

Are the fans loud on either machine?

The KAMRUI runs at 28W and rarely gets hot. Its fan is nearly silent during office work. The GMKtec has a more aggressive fan curve due to higher TDP. Under heavy load you’ll hear a whir, but it’s not annoying. Idle, both are quiet. If silence is critical, go with the Kamrui.
