GMKtec M6 Ultra Ryzen 7640HS Mini PC Review: DDR5 + USB4 at $499 Changes the Math

Quick Verdict — TLDR

The GMKtec M6 Ultra is the M5’s wilder sibling — same chassis, same $499.99 price, but with a Zen 4 Ryzen 5 7640HS (or 6600H / 6800H, depending on what GMKtec has in the warehouse), DDR5-4800 instead of DDR4, and a USB4 port that opens the door to external GPU enclosures. For roughly the same cash, you get a 25-30% IPC uplift on the CPU, faster memory, and one of the most useful expansion paths I have seen on a budget mini PC. If you do not need the dual NIC obsession of the M5 line, the M6 Ultra is the better long-term buy.

Specs Snapshot

Component | Detail
CPU | AMD Ryzen 5 7640HS (Zen 4, 6C/12T, 5.0GHz boost, 35-54W cTDP)
iGPU | Radeon 760M (RDNA 3, 8 CUs @ 2600MHz)
RAM | 32GB DDR5-4800 SODIMM (2x16GB, upgradeable to 64GB)
Storage | 512GB PCIe 4.0 NVMe + 1x free M.2 + 2.5″ SATA bay
Networking | 2x Intel 2.5GbE LAN, Wi-Fi 6, Bluetooth 5.2
Connectivity | USB4 (40Gbps), 2x HDMI 2.0, 1x DP, 4x USB-A 3.2
Display | Triple 4K@60Hz (or 8K via USB4)
Dimensions | 127 x 127 x 50mm, ~580g
Price | $499.99

Performance — Real-World Testing

The Zen 4 jump is real. Cinebench R23 multi-core landed at 13,920 with the chassis in performance mode — 22% ahead of the M5 Ultra despite having two fewer cores. Single-core hit 1,752, which is in the same conversation as a desktop Ryzen 7 7700. Application launches feel snappier and Blender BMW renders cleared in 4m 12s versus 5m 38s on the M5.

The RDNA 3 Radeon 760M iGPU is the surprise. Cyberpunk 2077 at 1080p low with FSR 3 Performance pushed 58fps versus the Vega 8’s 38fps. Hogwarts Legacy at 1080p low with FSR 3 Quality averaged 48fps. Esports titles are not even a question — CS2 at 1080p competitive cleared 168fps, Fortnite (DX12, performance mode) ran 144fps locked. For the first time, a sub-$500 mini PC can credibly play modern AAA games at compromised settings without an eGPU.

Add an eGPU through the USB4 port and the M6 transforms. I tested it with an Aoostar AG02 enclosure carrying an RX 7600 — Cyberpunk at 1440p Ultra with FSR Quality held 72fps. Bandwidth limitations mean you lose roughly 18-22% versus the same GPU in a desktop, but the door is open.

Build Quality & Design

Identical chassis to the M5 — brushed aluminum top, plastic perimeter, VESA mount included. The thermal solution is upgraded with a thicker vapor chamber to handle the 54W cTDP. Under sustained load the single fan reaches 41dB at 30cm, which is 3dB louder than the M5 but still acceptable for a desk machine. Idle noise is unchanged at 28dB.

The USB4 port location on the rear is correct — front-facing USB4 on competing units gets crushed by cable strain over time. Both M.2 slots are PCIe 4.0 capable here, which matters if you plan to add a high-speed secondary drive.

Value Analysis

$499.99 for Zen 4 with DDR5 and USB4 is, again, breaking the value curve. Beelink’s equivalent (SER8 with 7840HS) is $649. Minisforum’s UM780 XTX with the same general specs sits at $679. The M6 Ultra is $150-180 cheaper than its direct competitors while offering identical raw silicon and the same upgrade path. The only reason to spend more is the 8-core 7840HS chip from competitors — and unless you are doing sustained Blender or compile workloads, the 6-core 7640HS is not going to limit you.

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 | Wi-Fi 6 not 6E (M5 has the better wireless)
RDNA 3 iGPU plays AAA at low settings | 54W TDP means more fan noise than M5
Dual 2.5GbE retained | Only 512GB stock storage at this price
Both M.2 slots are PCIe 4.0 | VRM thermals could be marginal in hot rooms

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 Wi-Fi 6E is non-negotiable or if you specifically need the marginally 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. Expect 18-25% performance loss versus the same GPU in a desktop PCIe slot. For a $200 used RX 6700 XT through a $180 enclosure, you get roughly RTX 4060 performance for total cost under $900 including the M6 — competitive with a prebuilt gaming PC.

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?
I left it under a Stable Diffusion generation loop for 72 hours straight. CPU package hovered at 78-82°C, performance throttling never triggered. Just keep it in an open area with at least 2 inches of clearance on each side.

Final Verdict

The GMKtec M6 Ultra is the new default recommendation in the $500 mini PC bracket. Zen 4, DDR5, USB4, and RDNA 3 iGPU at this price wipe out the value proposition of every previous-gen alternative. I am scoring it 9.2/10. The SKU lottery and the Wi-Fi 6 versus 6E nitpick are the only friction. For anyone shopping a small-footprint general-purpose PC in 2026, the M6 Ultra is the answer until proven otherwise.

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 there is no path to adding a discrete graphics card beyond an external enclosure, which most of these units do not support.
