Beelink SER9 Review

Overview

The Beelink SER9 is what happens when a mini PC maker stops optimizing for price and starts optimizing for performance. Its Ryzen AI 9 HX 370 — twelve cores (four Zen 5, eight Zen 5c), twenty-four threads, up to 5.1GHz — with the 16-compute-unit Radeon 890M is the strongest APU you can buy in a sub-1.2L box without paying Strix Halo money, and Beelink wraps it in the most premium chassis in the company's lineup. At a $999 launch price for 32GB/1TB (street pricing in 2026's memory crisis has run higher, with live listings around $1,225), it sits at the top of the mainstream mini PC stack.

For a gaming-hardware site, the SER9's relevance is direct: it is arguably the best plug-and-play Bazzite machine you can buy. The HX 370 appears throughout Bazzite's documented hardware shortlists, the Radeon 890M handles 1080p high-settings gaming without a discrete GPU, and the platform's NPU matters little for gaming but keeps the box relevant for AI-assisted upscaling experiments. Where the K8 Plus asks you to accept a value chassis, the SER9 asks you to pay for the good one — and the difference shows in every detail from the speakers to the OLED-style front panel lighting.

The honest framing: this is a premium APU mini PC at a moment when RAM prices have made premium mini PCs painful. TechRadar scored it 4.45/5, praising power well beyond its compact form while docking it for the price and the RAM situation — soldered LPDDR5X, non-upgradeable, which is the platform's inherent trade for that bandwidth.

Build Quality and Design

The SER9 ships in a 135.5 × 135.5 × 44.7 mm chassis — marginally larger than the K8 Plus — with a matte metal top, fabric-look side accents, and a build that reads as a deliberate answer to Apple's Mac mini industrial design. Beelink includes dual front-firing speakers (a genuine rarity on mini PCs, and better than TV speakers for couch gaming audio in a pinch), a built-in microphone array, and a physical camera-shutter-style feel to the construction that justifies the price tier.

The port layout is modern and complete: front USB4 and USB-A plus audio; rear USB4, dual USB-A (10Gbps), HDMI 2.1, DisplayPort 1.4, and 2.5GbE. Four display outputs total means triple-monitor productivity or a TV plus desk setup without adapters. The 120W GaN power supply is compact and quiet.

The internal design is the polar opposite of GMKtec's approach, and it is the SER9's single most important caveat. The HX 370 platform uses soldered LPDDR5X-7500 — 32GB or 64GB, chosen at purchase, never upgraded. There is a single M.2 2280 slot (PCIe 4.0); storage can grow, memory cannot. ServeTheHome's deep-dive review flagged exactly this: excellent engineering, but the RAM decision is a permanent one, and in a memory-price crisis, that permanence cuts both ways.

Key Features

• Ryzen AI 9 HX 370 (12C/24T Zen 5/Zen 5c, up to 5.1GHz, 50 TOPS NPU) — the flagship Strix Point APU
• Radeon 890M (16 RDNA 3.5 CUs) — the strongest commonly-available iGPU this side of Strix Halo
• 32GB LPDDR5X-7500 soldered (64GB option), single M.2 2280 PCIe 4.0 slot
• Dual USB4 (front + rear) with DP Alt Mode, plus HDMI 2.1 and DP 1.4 — quad display output
• 2.5GbE, Wi-Fi 6 (upgradable to the standard M.2 E-key card), built-in dual microphones
• Front-firing stereo speakers — unusual and genuinely useful for living-room setups
• VESA mount and Windows 11 Pro license; Bazzite/Linux community support documented for the platform

Performance

The HX 370 is a tier above the 8845HS in every dimension that matters for gaming. Published testing and owner data converge on:

• 1080p AAA gaming: high settings 45–60fps in most titles (Cyberpunk 2077, Elden Ring, Starfield), with FSR 3 frame generation pushing several past 80fps
• 1440p: playable at medium settings in most AAA titles — territory the 780M cannot reach
• Esports: 100fps-plus trivially; high-refresh 1440p esports is realistic
• CPU: multi-core throughput roughly 40–50% above the 8845HS; emulation headroom for Switch, PS3, and even early PS4-era titles in compatible emulators
• Thermals: sustained performance in a well-tuned envelope; fan noise under load is present but unobtrusive — quieter than the K8 Plus at full tilt, per owner comparisons across both platforms

The 890M's real advantage shows in settings headroom. On a 780M box you spend time dropping settings to hold 60; on the SER9 you set high and play. For a couch setup where fiddling with graphics menus from across the room is misery, that difference is worth real money.

Pros and Cons

Pros:

• Fastest mainstream mini PC APU available — CPU and iGPU both a clear tier above 8845HS hardware
• Genuinely premium chassis with speakers, mics, and quad display outputs
• Mature Bazzite/Linux support on a documented platform
• 65W sustained performance in a near-silent acoustic profile
• USB4 front and rear covers docking and eGPU (external enclosures) use cases

Cons:

• Soldered RAM — 32GB or 64GB is a purchase-time decision, permanently
• Memory-crisis street pricing has stretched the value case (live listings near $1,225 for 32GB/1TB)
• Single M.2 slot only; no second storage bay
• NPU is largely irrelevant for gaming workloads today
• No OCuLink — buyers wanting an eGPU path use USB4 enclosures at a bandwidth penalty

Who Should Buy This

The SER9 is the pick for the buyer who wants one box to be both a serious compact desktop and a console-style living-room gaming PC, and who will pay for the top mainstream APU to get it. It is the strongest "just works" Bazzite machine in this roundup. Buy the 64GB variant if any local-LLM, heavy multitasking, or future-proofing ambition exists, because there is no second chance on RAM. Skip it if the budget caps at $700 — the K8 Plus covers 80% of this experience for less money — or if a discrete-GPU box like the HX99G fits the budget, since a real dGPU beats any iGPU for AAA frame rates.

Alternatives to Consider

• GMKtec NucBox K8 Plus — the value alternative: ~70–75% of the SER9's performance for hundreds less, with upgradeable RAM and OCuLink
• Minisforum HX99G — discrete RX 6600M beats the 890M in raster; older CPU platform and larger chassis
• Valve Steam Machine — the closed-console alternative at $1,049 with SteamOS built in; non-upgradeable but zero-setup

Verdict

The Beelink SER9 is the best premium APU mini PC for the money if the money is available. It is faster, quieter, and better-built than everything below it, and its only structural flaw — soldered memory — is a trade the platform makes deliberately for bandwidth. In a memory-price crisis that flaw stings more than usual, and the value case depends on catching sane pricing. At a fair price, it is the strongest plug-and-play SteamOS-style machine money can buy this side of Valve's own hardware. 8/10 — Excellent; the premium pick for a no-compromise Bazzite build.
