Geekom XT1 Mega specifications and in-depth review

Geekom XT1 Mega

Manufacturer: Geekom

The Geekom XT1 Mega is a Mini-ITX form factor mini PC built around a laptop-class hybrid processor pairing six performance cores at 2.3 GHz with eight efficiency cores at 1.8 GHz, reaching a turbo of 5.1 GHz across 22 threads. It ships with 64GB of DDR5 RAM running at 5600 MHz and a 2TB NVMe SSD, housed in a 139 × 132 × 57.8 mm enclosure totaling just over 1060 cm³.

Connectivity is a strong point, with two Thunderbolt 4 ports alongside two USB 4 40Gbps ports, five USB 3.2 Gen 2 Type-A ports, one USB 2.0 port, two HDMI 2.0 outputs, one DisplayPort, and dual RJ45 Ethernet jacks. Audio is covered by both a 3.5 mm headset jack and an AUX input, while Wi-Fi 7 and Bluetooth 5.4 handle wireless. The integrated Arc Graphics 128EU GPU supports up to four simultaneous displays, turbos to 2350 MHz over PCIe 5, and covers DirectX 12, OpenGL 4.6, and OpenCL 3. Benchmark results include a PassMark multi-threaded score of 29,380 and a Geekbench 6 multi-core result of 11,950.

Pros
  • Two Thunderbolt 4 ports alongside two USB 4 40Gbps ports give the XT1 Mega a high-bandwidth connectivity profile that goes well beyond what most mini PCs offer
  • Dual RJ45 Ethernet ports allow simultaneous wired connections to two separate networks without needing an adapter or hub
  • 64GB of DDR5 RAM at 5600 MHz ships as standard, covering memory-intensive workloads without requiring an immediate upgrade
  • Wi-Fi 7 and Bluetooth 5.4 ensure compatibility with the latest wireless standards alongside older Wi-Fi generations
  • The integrated GPU supports up to four simultaneous displays, making multi-monitor desktop setups viable without a discrete card
  • Both a 3.5 mm headset jack and an AUX input are present, covering common audio connection needs out of the box
Cons
  • There are no USB-C ports of any standard below USB 4, meaning all conventional USB-C accessories require an adapter
  • The memory ceiling is fixed at 64GB with no upgrade path beyond what is already installed
  • HDMI outputs are version 2.0 rather than a newer standard, which may constrain bandwidth for very high refresh rate or high resolution display configurations
  • ECC memory is not supported, which rules the unit out for workloads where hardware-level memory error correction is a firm requirement
  • The clock multiplier is locked, leaving no option to tune processor frequency beyond factory-defined settings despite the 45W thermal headroom
Who is this for?

The Geekom XT1 Mega is well matched to users who need a compact desktop with a deep connectivity stack, particularly those working with Thunderbolt 4 peripherals such as high-speed external storage, docking stations, or professional displays — a capability rarely found in mini PCs. The 64GB of DDR5 RAM at 5600 MHz and a 45W processor with a 5.1 GHz turbo make it a practical fit for sustained multi-threaded workloads like video editing, software compilation, or data processing that benefit from both memory capacity and processor headroom. Users who need dual wired Ethernet connections for network separation, NAS access, or soft routing will also find the dual RJ45 configuration directly useful without additional hardware.

Who is this NOT for?

Users whose peripheral ecosystem relies on USB-C connectivity will encounter friction immediately, as there are no USB-C ports below USB 4 — every standard USB-C device needs an adapter to connect. The 64GB memory ceiling also represents the factory-installed capacity, meaning there is no upgrade path for workloads that may outgrow that limit over time, which could be a constraint in longer-term deployments. Additionally, the locked clock multiplier and the absence of ECC memory support make this unit unsuitable for users who require either processor tuning flexibility or hardware-level memory error correction for reliability-critical server-side or data-sensitive applications.
