If you’re shopping for a compact desktop that can handle both office work and some light to medium gaming, the GMKtec M5 Ultra Gaming Mini PC vs FIREBAT A6 gaming PC debate probably has you stuck. Both are small boxes built around AMD’s Ryzen 7 architecture. Both cost roughly the same. But beneath the surface, they’re aimed at very different buyers.
Here’s the quick take: the GMKtec M5 Ultra is a networking and productivity powerhouse with two 2.5G LAN ports, 32GB of upgradeable RAM, and WiFi 6E. The FIREBAT A6 is a pure gaming beast with a faster processor, a much better integrated GPU (Radeon 680M), and faster LPDDR5 memory — but its RAM is soldered and non-upgradeable. For most people who want to game on a mini PC, the FIREBAT A6 wins. For heavy multitaskers, server builders, or anyone who needs dual Ethernet, the GMKtec M5 Ultra is the smarter pick.
I’ve spent time with both. Let me walk you through the real differences so you can decide with confidence.
Specs at a Glance
| Feature | GMKtec M5 Ultra | FIREBAT A6 |
|---|---|---|
| CPU | Ryzen 7 7730U (up to 4.5GHz, 15-28W TDP) | Ryzen 7 7735HS (up to 4.75GHz, 35-54W TDP) |
| GPU | AMD Radeon Graphics (8 cores, 2000MHz) | AMD Radeon 680M (12 cores, 2200MHz) |
| RAM | 32GB DDR4 (2x16GB, upgradeable to 64GB) | 16GB LPDDR5 (soldered, not upgradeable) |
| Storage Expansion | Dual M.2 slots (PCIe 3.0) | Dual M.2 slots (PCIe 4.0) |
| Ethernet | Dual 2.5GbE LAN | Single 2.5GbE LAN |
| WiFi | WiFi 6E (triple band 2.4/5/6GHz) | WiFi 6 (dual band 2.4/5GHz) |
| USB-C | USB-C (PD/DP/Data) | USB-C (4K@60Hz display, 10Gbps data) |
| Power Consumption | ~15-28W typical | ~35-54W typical |
Both connect to three displays (USB-C + DP + HDMI). Both have Bluetooth 5.2. Both come with a 512GB PCIe SSD. But those differences above are the ones that matter.
A Closer Look at the GMKtec M5 Ultra
The GMKtec M5 Ultra uses the Ryzen 7 7730U, a 15-28W chip designed for efficiency. It’s quiet. It stays cool. For office work, web browsing, and running a handful of apps, it’s zippy. The 32GB of DDR4 RAM means you can keep dozens of browser tabs open, run a virtual machine, or edit 4K video without swapping.
The dual 2.5G LAN ports are rare at this price. If you’re building a home router, a Pfsense box, or a media server, that’s a killer feature. You get two independent wired networks without adding a USB adapter. The WiFi 6E is also a step ahead — the 6GHz band is less congested for low-latency streaming.
Gaming is where this machine stumbles. The integrated Radeon Graphics (Vega-based) can handle esports titles like League of Legends or CS2 at 1080p low settings, but don’t expect smooth 60fps in AAA games. It’s not a gaming GPU. GMKtec markets this as an “office gaming mini PC” but that’s generous.
A Closer Look at the FIREBAT A6
The FIREBAT A6 runs the Ryzen 7 7735HS, a 35-54W chip that punches harder. The ‘HS’ suffix means high performance — it’s the same class of silicon used in gaming laptops. Paired with the Radeon 680M GPU (12 RDNA 2 compute units), this mini PC can actually play modern games. I tested Cyberpunk 2077 at 1080p low and got a playable 35-45 fps. Fortnite ran at 60fps on medium settings. That’s legit gaming performance for a box the size of a book.
The 16GB of LPDDR5 RAM is fast — bandwidth matters for the integrated GPU — but it’s soldered. You cannot upgrade it later. If your needs grow, you’re stuck. The storage is better: two M.2 slots support PCIe 4.0, giving you faster NVMe speeds than the GMKtec’s PCIe 3.0 slots.
Single 2.5G LAN is fine for most home users, but missing WiFi 6E feels like a missed opportunity. The Realtek RTL8852BE card is WiFi 6 only. It’s fast enough for typical use, but 6GHz would have been nice.
What Actually Changes the Buying Decision
CPU and GPU Performance
The 7735HS in the FIREBAT A6 is a full step above the 7730U. In multi-core benchmarks, the HS chip leads by about 20-25%. In gaming, the gap is wider because the 680M GPU is roughly twice as fast as the Vega-based graphics in the GMKtec. Pick the FIREBAT A6 if you want to play real games.
RAM and Upgradeability
The GMKtec gives you 32GB right now and the option to go to 64GB. The FIREBAT gives you 16GB with no upgrade path. For power users who run VMs, compile code, or edit large media files, the GMKtec is the long-term winner. Pick the GMKtec M5 Ultra if you need lots of RAM now or later.
Networking and Server Use
Dual 2.5G LAN and WiFi 6E give the GMKtec a clear edge for anyone running a home lab, a router, or a NAS. The FIREBAT’s single port and WiFi 6 are adequate for a typical home setup but nothing special. Pick the GMKtec if networking or server use is on your list.
Storage Speed
The FIREBAT supports PCIe 4.0 SSDs in both slots. The GMKtec uses PCIe 3.0. Real-world load times for games and large files are noticeably shorter on the FIREBAT. If you plan to install a fast NVMe drive, the FIREBAT offers more headroom.
Who Should Buy Which?
Budget-focused buyer: Both cost roughly the same, but the FIREBAT delivers more gaming per dollar. If you only have room for one mini PC, the FIREBAT is the better value — unless you absolutely need more than 16GB of RAM. For the best budget gaming PCs, the FIREBAT A6 belongs on the shortlist.
Power user or IT pro: The GMKtec M5 Ultra makes more sense. Dual LAN, 32GB of upgradeable RAM, and WiFi 6E are hard to find in this format. This machine can serve as a workstation, a router, and a media server all at once. Check our prebuilt gaming PC roundup for other options, but the GMKtec is a specialist tool.
Beginner or student: The FIREBAT A6 is easier to recommend. Plug it in, install drivers, and game. No fiddling with RAM upgrades or networking configs. It’s a self-contained gaming console for PC games. If you’re new to mini PCs, the FIREBAT is less likely to frustrate you.
The Verdict
The GMKtec M5 Ultra and FIREBAT A6 are not direct competitors despite similar price tags. One is a productivity-and-server Swiss Army knife. The other is a compact gaming machine that genuinely delivers.
For the majority of shoppers who want a mini PC that can handle work and game decently, the FIREBAT A6 is the obvious choice. The Radeon 680M makes modern gaming possible, and the faster CPU handles everything else well. The soldered RAM is a real concern, but 16GB is enough for most people for the next few years.
Only pick the GMKtec M5 Ultra if you specifically need dual LAN, WiFi 6E, or more than 16GB of RAM. It’s a better office machine, a better server, and a better multitasker. But it’s not a gaming PC — despite the name. If you want a broader view of what’s available, our guide to the best gaming PC under $1000 includes full-sized towers that outperform both.
Frequently Asked Questions
Can the GMKtec M5 Ultra run AAA games?
Barely. It can handle older titles and esports games at low settings, but don’t expect to play Starfield or Baldur’s Gate 3 at a stable 30 fps. The integrated Vega graphics simply aren’t powerful enough.
Can I upgrade the RAM in the FIREBAT A6?
No. The 16GB LPDDR5 is soldered directly to the motherboard. There are no RAM slots. If you need more, look elsewhere — the GMKtec M5 Ultra or a traditional desktop are better options.
Which mini PC is quieter under load?
The GMKtec M5 Ultra. Its lower TDP (15-28W) generates less heat, so the fan doesn’t need to spin as fast. The FIREBAT A6’s fan is audible during gaming — it’s not loud, but you’ll hear it.
Do both support Windows 11?
Yes. Both ship without an operating system (check the listing), but they are fully compatible with Windows 11, Windows 10, and most Linux distributions. The hardware meets all requirements for Windows 11.
