GMKtec M6 Ultra Ryzen 7640HS Mini PC Review: DDR5 and USB4 at a Budget Price
Quick Verdict — TLDR
The GMKtec M6 Ultra is the step-up sibling of the M5 Ultra: a similar compact chassis, but built around a Zen 4 Ryzen 5 7640HS with DDR5-4800 memory instead of DDR4 and a USB4 port that opens the door to external GPU enclosures. Listings sell it in several configurations, and some titles mention 6600H or 6800H chips, so check the CPU line before you buy. Based on the maker specifications and published reviews, it is a strong value pick in the roughly $500 bracket for office work, media and casual gaming. If you do not need the M5 line’s lower power draw, the M6 Ultra is the better long-term buy.
Updated October 2026 – specifications cross-checked against the maker listings and published third-party reviews; unavailable listings were replaced.
Is the GMKtec M6 Ultra Worth Buying?
Yes, for most buyers who want a small Windows PC for office work, media and casual gaming. The GMKtec M6 Ultra pairs a Ryzen 5 7640HS (6 cores, 12 threads, up to 5.0GHz) with Radeon 760M graphics, DDR5 memory, USB4, Wi-Fi 6E and dual 2.5GbE for roughly $500. It is not a replacement for a gaming tower, and its plastic body and audible fan under load are the trade-offs.
Which GMKtec M6 Ultra Configuration Should You Pick?
GMKtec sells the M6 Ultra in several memory and storage bundles, and the CPU name in the title can differ between listings. Match the bundle to your use before paying for extras.
| Configuration | Memory and storage | Typical price tier | Best for |
|---|---|---|---|
| Entry bundle | 16GB DDR5 · 512GB SSD | around $500 | Office, browsing, media |
| Storage bundle | 16GB DDR5 · 1TB SSD | around $500-$550 | Light gaming with a bigger library |
| Top bundle | 32GB DDR5 · 1TB SSD | around $680 | Creative work, multitasking, emulation |
Because the mini PC has two SODIMM slots and two M.2 slots, buying the entry bundle and upgrading later is often cheaper than paying for the top bundle, as long as you confirm the memory type and slot layout on the maker page first.

Performance Expectations
On paper the Ryzen 5 7640HS is a six-core, 12-thread Zen 4 chip that boosts up to 5.0GHz with a configurable 35 to 54W power limit. It uses newer Zen 4 cores than the Zen 3 based Ryzen 7 7730U in the M5 Ultra, while the eight-core Ryzen 7 7840HS in pricier mini PCs keeps an edge in sustained multi-core jobs. This section is based on specifications and published third-party reviews, not our own bench runs.
The Radeon 760M integrated GPU (RDNA 3, 8 compute units, up to 2600MHz) is the gaming part. Published reviews describe esports titles as playable at 1080p medium settings, while AAA games need low to medium settings with FSR upscaling. Emulation of older consoles such as PS2 and GameCube is also reported to run well. Do not expect high settings in modern AAA releases; a discrete GPU is what changes that.
The USB4 port can drive an external GPU enclosure, which turns the M6 Ultra into a more capable gaming machine later. Expect a performance loss compared with the same card in a desktop slot because the link has far less bandwidth than PCIe x16, and compatibility depends on the enclosure.
Build Quality & Design
The M6 Ultra uses a compact plastic chassis, and reviews note that it lacks the premium feel of metal mini PCs. Dimensions are listed at about 128.8 x 127 x 47.8mm and weight at roughly 528g, small enough to mount behind a monitor. Reviewers report that the fan is clearly audible under load, which is typical for a chip running at a 35 to 54W power limit; idle and light use are much quieter.
Ports and expansion are the strong points. The USB4 port sits on the front, alongside HDMI 2.0, DisplayPort 1.4, USB 3.2 ports, dual 2.5G Ethernet, Wi-Fi 6E and Bluetooth 5.2 on the usual specification. Two SODIMM slots take DDR5 memory, and two M.2 NVMe PCIe 4.0 slots make adding a second drive simple. There is no SD card reader.
Value Analysis
At around $500 for Zen 4, DDR5 and USB4, the M6 Ultra undercuts most mini PCs built on the eight-core Ryzen 7 7840HS, which usually sit in a higher price tier from brands such as Beelink and Minisforum. The main reason to pay more is the extra two cores for sustained rendering or compiling; for office work, media and casual gaming, the six-core 7640HS is unlikely to limit you. Configurations vary, so compare RAM and SSD size before choosing: a 16GB and 512GB model costs less, while a 32GB and 1TB model sits near the top of the range.
Pros & Cons
| Pros | Cons |
|---|---|
| Zen 4 + DDR5 at a Zen 3 + DDR4 price | SKU lottery: 6600H or 6800H possible instead of 7640HS |
| USB4 enables eGPU expansion | Plastic chassis; fan clearly audible under load |
| RDNA 3 iGPU plays AAA at low settings | 54W TDP means more fan noise than M5 |
| Dual 2.5GbE retained | Base configurations ship with only 512GB |
| Both M.2 slots are PCIe 4.0 | CPU temperatures approach 90C in sustained load per reviews |

Pros: OCuLink for an external GPU; stronger iGPU; same brand ecosystem.
Cons: Costs about $180 more than the M6 Ultra.
Skip it if you only need office and casual gaming performance.
Beelink EQR7 – Best Pick for a Quiet Everyday Desktop
The Beelink EQR7 is an eight-core Ryzen 7 7735U mini PC with 24GB of LPDDR5 and a 500GB SSD. It targets office, streaming and everyday use rather than gaming, at around $540.
- Ryzen 7 7735U, 8 cores and 16 threads, up to 4.75GHz
- 24GB LPDDR5 memory
- 500GB M.2 PCIe 4.0 SSD
- 4K at 60Hz on dual displays
- Built-in power supply, Wi-Fi 6, Bluetooth 5.2
Pros: Built-in power supply; 24GB memory; compact.
Cons: Weaker integrated graphics than the M6 Ultra; memory is soldered LPDDR5.
Skip it if you want to upgrade RAM later or play modern games.
Who Should Buy This
The M6 Ultra is the better pick over the M5 for anyone who values raw CPU performance, plans to game even casually on the iGPU, or wants the eGPU escape hatch. Pick the M5 Ultra instead only if you specifically need the lower power draw for an always-on home-lab role. Gamers, content creators on a budget, and anyone planning to keep this machine for 4+ years should default to the M6.
FAQ
Q: Will an eGPU through USB4 actually deliver usable gaming performance?
Yes, with caveats. An external GPU enclosure over USB4 loses a noticeable share of performance compared with the same card in a desktop PCIe slot, and compatibility varies by enclosure. Check the enclosure maker’s compatibility list and add up the total cost before choosing this route over a small desktop.
Q: Is the 6-core 7640HS limiting for content creation?
For Photoshop, Lightroom, basic Premiere editing, and Davinci Resolve color grading on 1080p footage — no. For 4K H.265 timelines, sustained Blender renders, or code compilation of large projects, the 8-core 7840HS in pricier competitors will save you noticeable time.
Q: Does the iGPU support AV1 hardware encoding?
Yes. The RDNA 3 Radeon 760M includes the VCN 4.0 engine with AV1 encode/decode, dual H.265, and H.264. This is a meaningful win for OBS streamers and anyone running Plex/Jellyfin with hardware transcoding.
Q: Can I run it 24/7 without throttling?
Reviewers report CPU temperatures approaching 90C under sustained load, so give it room. Keep it in an open area with at least 2 inches of clearance on each side and avoid enclosed cabinets. For an always-on role, the lower-power M5 Ultra is the easier fit.
Final Verdict
The GMKtec M6 Ultra is a strong default in the $500 mini PC bracket. Zen 4, DDR5, USB4, dual 2.5GbE and an RDNA 3 iGPU at this price make most previous-generation alternatives hard to justify. The configuration lottery (check which CPU your listing names), the plastic chassis and the audible fan under load are the main compromises. For a small-footprint general-purpose PC in 2026, it is an easy shortlist entry.

Frequently Asked Questions
What gaming performance can the Ryzen 7640HS integrated graphics deliver?
The Radeon 760M integrated graphics runs esports titles such as CS2, Valorant, League of Legends and Rocket League well above 60 fps at 1080p with medium settings. Modern AAA games need 720p or 1080p low settings with FSR upscaling to hold playable frame rates, typically in the 30 to 45 fps range. It is a capable casual gaming machine, not a substitute for a discrete card.
Does memory speed affect integrated graphics performance?
Significantly, more than on a desktop with a discrete card. Integrated graphics share system memory for frame buffer and texture access, so faster DDR5 with dual-channel population directly raises frame rates, sometimes by twenty percent or more. Always run two matched SODIMM sticks rather than one, and choose the fastest speed the platform officially supports rather than the cheapest kit.
Can I upgrade the 32 GB of memory and the storage?
Most GMKtec M-series units use two accessible SODIMM slots and an M.2 2280 NVMe slot, with some models offering a second M.2 or a 2.5 inch SATA bay. Removing the base plate exposes them without special tools. Confirm the maximum supported capacity, commonly 64 GB, before buying larger sticks, and reapply the thermal pad if you swap the main drive.
How loud does it get under sustained load?
Compact chassis rely on a small high-speed blower, so gaming and rendering sessions make it clearly audible, typically a steady whoosh rather than a whine. Idle and light desktop work are near silent. Placing the unit on an open surface rather than inside a cabinet, and keeping the underside vents clear, meaningfully reduces both fan speed and clock throttling.
Is this a sensible replacement for a full desktop?
For browsing, office work, media playback, light content creation and casual gaming, yes, and it uses a fraction of the power of a tower. It falls short if you want high-refresh 1440p gaming, GPU rendering or heavy compiling, since the only route to a discrete graphics card is an external enclosure over USB4, with a performance loss and varying compatibility.
Is the GMKtec M6 Ultra good for gaming?
It is good for casual gaming. Esports titles are reported playable at 1080p medium settings, and modern AAA games need low to medium settings with FSR. For higher settings you need an external GPU through USB4 or a different machine.
Which Ryzen chip does the GMKtec M6 Ultra use?
The main model uses the Ryzen 5 7640HS, a Zen 4 chip with 6 cores and 12 threads. Some listing titles mention 6600H or 6800H as upgraded options, so read the product page and the system information after setup to confirm what you received.
Does the GMKtec M6 Ultra have Wi-Fi 6E and USB4?
Most listings specify Wi-Fi 6E, Bluetooth 5.2 and a USB4 port, with dual 2.5GbE for wired networking. One older listing title says Wi-Fi 6, so check the bundle you are buying.
