BOSGAME M4 Review: OCuLink + Dual 2.5G
Under $520 β Worth It in 2026?
A Ryzen 7 8745HS mini PC with OCuLink, USB4, dual 2.5G LAN and Wi-Fi 6E β all for under $520. That’s an unusual combination at this price. We break down exactly what you get, what you don’t, and who should buy it.
The BOSGAME M4 is the most feature-complete mini PC under $520 in 2026. For this price you get OCuLink, USB4 at 40 Gbps, dual 2.5 Gbps Ethernet, Wi-Fi 6E, and an upgradable 32 GB DDR5 configuration β a combination that rivals machines priced $150β200 higher from Beelink and Minisforum. The Ryzen 7 8745HS handles 1080p gaming, 4K video editing and productivity without issue. The main limitation: the Radeon 780M iGPU is one generation behind the 890M found in ~$940 machines. If you plan to add an eGPU later, the BOSGAME M4 is the smartest starting point under $500.
The OCuLink Advantage β Why It Matters at This Price
OCuLink delivers PCIe 4.0 Γ4 bandwidth (up to 40 Gbps) to an external GPU. At $489, the BOSGAME M4 is one of very few mini PCs to include it β most competitors at this price omit it entirely.
Most mini PC owners at this price point eventually hit a wall: the integrated GPU handles everyday gaming, but demanding titles at higher resolutions expose its limits. The usual answer is to buy a new machine. OCuLink offers a different path. Connect an eGPU dock β BOSGAME sells their own GVP7600 with a Radeon RX 7600M XT, or you can use third-party docks with any PCIe GPU β and the M4 transforms into a machine capable of 1440p and even 4K gaming for a fraction of a new PC’s cost.
The practical math: an RTX 4060 eGPU dock costs $200β$350 used. Total investment for the M4 + eGPU: under $800. That’s still less than a Ryzen AI 9 HX 370 machine β and you get a discrete GPU with dedicated VRAM, which handles large local AI models better than an iGPU with shared memory.
Full Specifications
The BOSGAME M4 uses the Ryzen 7 8745HS β a Zen 4 “Hawk Point” chip from AMD’s 2024 lineup. It’s not the latest Strix Point architecture, but it delivers strong sustained performance and excellent iGPU gaming for its class.

CPU & Gaming Performance
The Ryzen 7 8745HS scores approximately 15,000β17,500 points in Cinebench R23 multi-core β strong for its class, and less than 10% behind the Intel Core Ultra 7 255H at a significantly lower price point. The Radeon 780M at 2700 MHz delivers solid 1080p gaming performance.
Based on independent community benchmarks published by TechRadar, WCCFtech, and LinuxLinks (all Q4 2025 β Q1 2026), here is what the BOSGAME M4 delivers in real-world use:
Performance Ratings β All Use Cases
Gaming benchmarks (1080p, iGPU only, sourced from community tests)
| Game | Settings | FPS (avg) | Verdict |
|---|---|---|---|
| CS2 | 1080p Medium | 80β110 fps | Excellent |
| Fortnite | 1080p Medium | 60β85 fps | Very playable |
| Minecraft (Java) | 1080p, Sodium | 200+ fps | Excellent |
| Cyberpunk 2077 | 1080p Low | 35β48 fps | Playable w/ FSR |
| Elden Ring | 1080p Medium | 40β55 fps | Acceptable |
| GTA V | 1080p High | 65β90 fps | Very smooth |
| Cyberpunk 2077 | 1440p Medium + FSR | 28β40 fps | Marginal |
| Any title + eGPU (RTX 4060) | 1440p High | 80β120+ fps | Excellent |
For CPU-intensive tasks, LinuxLinks’ independent Linux benchmark comparison found the BOSGAME M4 was less than 10% slower than the Intel Core Ultra 7 255H β a chip that retails in machines $300 more expensive β while achieving 20% higher scores than the 255H in some multi-core tests. The value proposition for productivity users is strong.
Design, Ports & Build Quality
The BOSGAME M4 measures 129 Γ 129 Γ 48 mm β roughly the same footprint as a CD case. The honeycomb-patterned plastic chassis is light but functional. Port selection is genuinely exceptional for the price: you get more connectivity here than on machines costing $200 more.
The design won’t win awards β it’s plastic where competitors use aluminium alloy β but the build is solid, without flex or rattles. BOSGAME’s thermal design on the M4 keeps temperatures managed: sustained CPU workloads run at 28W TDP, with fan noise becoming audible (approximately 38β42 dB) under extended gaming loads. At idle and light use, it’s effectively silent.
Port layout is pragmatic: two USB 3.2 Gen2 ports on the front for easy access to drives and peripherals, plus the USB4 port, are the most-used connections. The rear carries the display outputs (HDMI 2.0, DP 1.4), dual 2.5G Ethernet, and the OCuLink port. The power button has been noted in community reviews to be slightly hard to read under certain lighting conditions β a minor cosmetic issue.
One practical advantage over sealed designs: the SO-DIMM slots and second M.2 slot are accessible via a small Phillips screwdriver. Upgrading from 32 GB to 64 GB or adding a second SSD takes about 10 minutes. There’s no tool-less mechanism like some ASUS NUC models, but it’s far less involved than machines requiring thermal paste replacement for any upgrade.
Who Should Buy the BOSGAME M4?
BOSGAME M4 vs the Competition
At $489, the M4 competes most directly with the Beelink SER8 (~$499) and Minisforum UM890 (~$479). Against both, it wins on connectivity. Against the Reatan X7 (~$899), it loses on RAM (32 GB vs 64 GB) and price-to-spec ratio for that higher budget.
| Machine | CPU | RAM | OCuLink | Dual 2.5G | Wi-Fi | Price |
|---|---|---|---|---|---|---|
| BOSGAME M4 | Ryzen 7 8745HS | 32 GB DDR5 | β | β | 6E | ~$489 |
| Beelink SER8 | Ryzen 7 8745HS | 32β64 GB DDR5 | β | Single | 6E | ~$499 |
| Minisforum UM890 | Ryzen 9 8945HS | 32 GB DDR5 | β | Single | 6E | ~$479 |
| Reatan X7 | Ryzen 7 8745HS | 64 GB DDR5 | β | β | 7 | ~$899 |
| Peladn HO5 | Ryzen AI 9 HX 370 | 32 GB LPDDR5X | β | β | 7 | ~$940 |
Prices approximate as of April 2026. Check current listings for latest pricing.
The Beelink SER8 is the most direct comparison: same processor, similar price, but no OCuLink and only single 2.5G LAN. For users who are certain they’ll never add an eGPU, Beelink’s stronger brand reputation and BIOS history gives it a slight edge. For users who want the upgrade path, the BOSGAME M4 wins clearly.
The Reatan X7 costs nearly double but adds 64 GB RAM, Wi-Fi 7, and HDMI 2.1. If your budget is closer to $900, the X7 is better value overall. The M4 is the right choice when the budget genuinely tops out around $500.
Pros & Cons

Final Verdict
The BOSGAME M4 occupies a specific and genuinely useful niche: it’s the most capable mini PC under $520 for users who want OCuLink, dual 2.5G Ethernet, and USB4 together. No competitor at this price delivers all three. The Ryzen 7 8745HS performs well for everything from gaming to content creation, and the platform’s upgradability means a 32 GB purchase today isn’t a permanent limitation.
The real limitation is positioning. If your budget reaches $900, the Reatan X7 offers 64 GB RAM, Wi-Fi 7, and HDMI 2.1 with OCuLink for a much stronger package. If gaming performance is the priority, spending up to the Peladn HO5 gets you the Radeon 890M, NPU, and a generation-newer chip. The M4 makes most sense as a budget-first purchase with a clear upgrade roadmap β it’s the right foundation to build on, not the final destination.
