GEEKOM A7 MAX vs Reatan Alloy 9 vs GMKtec K11: Best Ryzen 9 Mini PC Under $900 [2026]

GEEKOM A7 MAX

The Short Answer

Three Ryzen 9 mini PCs, three very different value propositions. The GMKtec K11 at ~$799 is the best overall value: 32GB RAM, 2TB SSD, dual 2.5GbE, and OCuLink for eGPU expansion. The GEEKOM A7 MAX at ~$699 has 550 Amazon reviews proving reliability and a 3-year warranty, Dual 2.5GbE, and WiFi 7, but only 16GB RAM. The Reatan Alloy 9 at $899 is the dark horse: 32GB RAM, 2.5GbE, and 4.8 stars from 9 reviews — but Reatan is an unknown brand.

Best overall value: GMKtec K11 ($739 with 32GB/2TB, dual 2.5G, OCuLink).

Best for risk-averse buyers: GEEKOM A7 MAX (550 reviews, 3-year warranty).

Best early impressions: Reatan Alloy 9 (4.8 stars but only 9 reviews — proceed with caution).

CPU and GPU Performance

All three systems use AMD’s Ryzen 9 H-series processors — essentially the same silicon with minor clock speed variations.

GEEKOM A7 MAX: Ryzen 9 7940HS (Zen 4, 4nm). 12 cores / 24 threads, up to 5.0 GHz boost. Radeon 780M GPU with 12 RDNA 3 compute units (768 shaders).

Reatan Alloy 9: Ryzen 9 7940HS — identical to the A7 MAX. Same 12C/24T, same 5.0 GHz, same 780M GPU.

GMKtec K11: Ryzen 9 8945HS (Zen 4, refreshed). 12 cores / 24 threads, up to 5.0 GHz boost. Radeon 780M GPU. The “8945HS” is a Hawk Point refresh — marginally improved efficiency over the 7940HS, but real-world performance is identical.

AI compute: None of these systems have a dedicated NPU. They rely on CPU/GPU compute for AI workloads. For Ollama LLM inference:

7B models: ~25-40 tokens/sec on all three
13B models: ~10-20 tokens/sec on all three
34B models: Limited by RAM (16GB on A7 MAX caps at 13B comfortably)

GPU performance: The 780M handles 1080p gaming at medium settings and Stable Diffusion XL image generation in 12-18 seconds. ROCm support on Linux is solid for RDNA 3.

Memory and Storage

This is where the K11 pulls ahead:

GEEKOM A7 MAX: 16GB DDR5 SO-DIMM. This is the bare minimum for 2026. For general use and 7B LLMs, it’s adequate. For 13B+ models or heavy VM workloads, plan to upgrade to 32GB (~$80-100 for extra 16GB).

Reatan Alloy 9: 32GB DDR5 SO-DIMM. Ready out of the box for 13B LLMs and moderate VM workloads. Upgradeable to 64GB.

GMKtec K11: 32GB DDR5 SO-DIMM. Same as Reatan, but the K11 also includes a 2TB SSD vs 1TB on the others. For LLM workloads with multiple models, the extra storage matters.

Storage comparison:

A7 MAX: 1TB PCIe 4.0 NVMe
Reatan Alloy 9: 1TB PCIe 4.0 NVMe
K11: 2TB PCIe 4.0 NVMe (dual M.2 slots)

Networking and Connectivity

GEEKOM A7 MAX: Dual 2.5GbE. WiFi 7 and Bluetooth 5.3. WiFi 7 is current-gen and future-proofs your purchase.

Reatan Alloy 9: Single 2.5GbE (Realtek controller). WiFi 6E and Bluetooth 5.2. Adequate for general use, but Realtek NICs may require manual driver installation on some Linux distributions.

GMKtec K11: Dual 2.5GbE Intel NICs (i226-V). WiFi 6 and Bluetooth 5.3. The dual Intel NICs are the gold standard for homelab use — run OPNsense with WAN on one port and LAN on the other, no USB adapters needed.

OCuLink (K11 only): This is the K11’s killer feature. OCuLink is a direct PCIe 4.0 x4 connection for external GPUs. Connect an eGPU for desktop-class AI compute or gaming when the 780M isn’t enough. Neither the A7 MAX nor Reatan offers this.

Power Consumption

Metric	A7 MAX	Alloy 9	K11
Idle (W)	~7W	~8W	~10W
Load (W)	~65W	~65W	~65W
Annual Cost (24/7 idle)	~$7.36/year	~$8.41/year	~$10.51/year

Annual cost calculated at $0.12/kWh. Sources: Guru3D, ServeTheHome, community estimates.

The A7 MAX is the most power-efficient at ~7W idle — about $7.36/year to run 24/7. The K11 draws ~10W idle due to the dual NICs and additional features, but $10.51/year is still negligible for always-on homelab workloads.

Design and Build Quality

GEEKOM A7 MAX: Compact aluminium chassis with GEEKOM’s established design language. Build quality is solid — the 550 reviews at 4.6 stars confirm reliability over time. The IceBlast cooling system keeps thermals manageable. Port selection is adequate but the lack of 2.5GbE is noticeable.

Reatan Alloy 9: Aluminium chassis similar to competitors. Build quality appears solid based on early reviews, but the 9-review sample size is too small for long-term reliability conclusions. Port selection includes 2.5GbE and USB4 — no major omissions.

GMKtec K11: Larger chassis than competitors to accommodate the dual NICs and OCuLink port. Build quality is good but GMKtec has less review history than GEEKOM. The OCuLink port and dual 2.5GbE justify the larger footprint for homelab users.

Reviews and Brand Trust

GEEKOM A7 MAX: 550 Amazon reviews at 4.6 stars. This is social proof you can’t ignore. GEEKOM has established support channels and a 3-year warranty — the longest in the industry. For risk-averse buyers, this matters.

Reatan Alloy 9: 9 Amazon reviews at 4.8 stars. Early impressions are positive, but 9 reviews is statistically insignificant. Reatan is an unknown brand — no track record, no established support network. The 4.8-star rating could hold up, or it could drop as more reviews come in.

GMKtec K11: Limited reviews (new listing). GMKtec has a growing presence but less brand recognition than GEEKOM. The 1-year warranty is industry-standard.

Price and Value

At $739, the K11 is exceptional value:

32GB RAM (vs 16GB on A7 MAX)
2TB SSD (vs 1TB on others)
Dual 2.5GbE Intel NICs (vs single or none on others)
OCuLink for eGPU (unique at this price)

At $949, the A7 MAX costs $210 more but delivers:

550 reviews proving reliability
3-year warranty
Only 16GB RAM (needs upgrade)
No 2.5GbE (needs USB adapter)

At $899, the Reatan Alloy 9 sits in the middle:

32GB RAM
2.5GbE
Unknown brand (9 reviews)
No OCuLink

Value ranking:

K11 ($739) — best specs per dollar
Alloy 9 ($899) — middle ground, unproven brand
A7 MAX ($699) — premium for warranty and reviews

Real-World Use Cases

For Homelab (Proxmox, OPNsense)

K11 wins decisively. Dual 2.5GbE Intel NICs, OCuLink for future expansion, 32GB RAM, and 2TB storage. The A7 MAX needs a USB Ethernet adapter, and the Reatan has only single NIC.

For Local LLMs (Ollama)

K11 wins. 32GB RAM handles 13B-34B models comfortably. The A7 MAX’s 16GB caps at 7B-13B models unless upgraded. All three run 7B models at 25-40 tokens/sec.

For Daily Use (Office, Media)

A7 MAX wins. The 550 reviews and 3-year warranty provide peace of mind. WiFi 7 is current-gen. The compact chassis fits anywhere. 16GB RAM is adequate for general use.

For Budget Buyers

K11 wins. At $739, you get more RAM, more storage, better networking, and OCuLink. The $210 savings vs A7 MAX can go toward a RAM upgrade or external storage.

Final Verdict: Which Should You Buy?

Buy the GEEKOM A7 MAX if:

You value warranty and community proof above all else (3 years, 550 reviews)
You’re risk-averse and prefer established brands
You only need 16GB RAM for general use

Frequently Asked Questions

Is the Ryzen 9 8945HS (K11) better than the 7940HS (A7 MAX, Alloy 9)?

Marginally. The 8945HS is a Hawk Point refresh with improved efficiency, but real-world performance is nearly identical. Both are 12C/24T Zen 4 at up to 5.0 GHz with the same 780M GPU. Don’t choose based on CPU alone — consider RAM, storage, and networking.

Can these mini PCs run local LLMs?

Yes, but with limitations. All three handle 7B models at 25-40 tokens/sec. The 32GB systems (K11, Alloy 9) handle 13B-34B models. The A7 MAX’s 16GB RAM caps at 7B-13B models unless upgraded. None have dedicated NPUs — they rely on CPU/GPU compute.

Does the K11’s OCuLink work with all eGPUs?

OCuLink supports any PCIe 4.0 x4 eGPU enclosure. Popular options include the GPD G1, OneXGPU, and DIY enclosures with desktop GPUs. Performance is near-native (5-10% loss vs direct PCIe connection).

Is 16GB RAM enough on the A7 MAX?

For general use and 7B LLMs, yes. For 13B+ models or heavy VM workloads, plan to upgrade to 32GB (~$80-100 for extra 16GB). The K11 and Alloy 9 include 32GB out of the box.

Why does the A7 MAX cost more with fewer features?

You’re paying for GEEKOM’s 3-year warranty and 550 reviews proving reliability. For risk-averse buyers, this justifies the premium. For spec-focused buyers, the K11 delivers better value.

Which has the best Linux support?

The K11’s Intel i226-V NICs have excellent out-of-the-box Linux support. The Reatan’s Realtek NIC may require manual driver installation. The A7 MAX needs a USB Ethernet adapter for 2.5GbE, which adds complexity.
