EGLOBAL mini pc: G5A‑8250U vs G8‑8665U Industrial Mini PC

Both EGLOBAL G5A‑8250U and G8‑8665U are fanless‑designed industrial mini PCs. Adopting full‑aluminum housing for passive cooling, they support 7×24‑hour continuous operation, ideal for industrial control, device interconnection, automation and other scenarios. Though sharing partial hardware architecture, the two models differ notably in CPU performance, port configuration and storage expandability.

The G5A‑8250U is powered by Kaby Lake Intel Core i5‑8250U processor, 4‑core 8‑thread, base frequency 1.6 GHz, max turbo frequency 3.4 GHz with 15 W TDP and UHD 620 integrated graphics. It is equipped with dual Intel Gigabit Ethernet ports and six DB9 COM ports. COM1 and COM2 can be switched between RS232 / RS422 / RS485 via BIOS. It delivers dual‑display output over VGA + HDMI 1.4, along with GPIO, PS/2 and audio jacks. The USB layout includes four USB2.0 and four USB3.0 ports.

For wireless expansion, one half‑size mini‑PCIe slot is reserved for Wi‑Fi & Bluetooth modules, and one full‑size mini‑PCIe slot for 3G / 4G modules with onboard SIM card slot. Wireless modules and external antennas are not pre‑installed and need separate purchase. Storage supports mSATA SSD plus a 2.5‑inch SATA drive for dual‑drive setup. It features watchdog, power‑on auto‑boot, RTC, Wake‑on‑LAN and PXE boot, and supports wall‑mount installation. Unit dimension: 23017550 mm.

As the higher‑end variant, G8‑8665U runs on Whiskey Lake Intel Core i7‑8665U, 4‑core 8‑thread CPU with max turbo frequency up to 4.8 GHz and 8 MB cache at 15 W TDP, delivering stronger computing performance than G5A‑8250U. It also comes with six DB9 COM ports, among which four ports support RS422 / RS485 for enhanced serial‑port programmability. Dual DDR4 SO‑DIMM memory slots are adopted. Storage is upgraded to triple‑drive support: mSATA, M.2 NVMe 2280 and 2.5‑inch SATA, providing superior expandability.

It keeps half‑size & full‑size mini‑PCIe slots plus onboard SIM slot for wireless options, and adds LPC, USB and PCIe extended I/O. Operating temperature ranges from ‑20 ℃ to 60 ℃. Industrial‑grade functions cover watchdog, power‑on wake‑up, RTC, WOL, PXE and hardware reset. It fits harsh industrial environments, backed by 3‑year factory warranty with failure rate below 1%.

Common features: Fanless silent operation, dual Gigabit LAN, onboard SIM slot, rich industrial I/O. Wi‑Fi / 4G modules are sold separately.

Selection guide: Choose G5A‑8250U for general industrial projects with budget constraints. Pick G8‑8665U for higher CPU performance, triple‑storage capability and flexible serial‑port configurations.
