GT13 Pro Overview: Flagship Geekom Mini PC
Performance Profile
The GT13 Pro is Geekom’s top-tier mini PC, featuring Intel’s powerful 13th-gen i9-13900H mobile processor. Performance comparison:
- vs Apple M4: ~15% faster multi-threaded, ~5% slower single-threaded
- vs M4 Pro: Competitive but slower in GPU-accelerated tasks (no dedicated GPU like M4)
- Best at: Development, virtual machines, workstation-class computing, sustained multi-threaded workloads
Upgradeability Advantage
Unlike sealed Apple Silicon Mac Minis, the GT13 Pro lets you:
- Upgrade RAM to 64GB (DDR4-3200 SO-DIMM)
- Replace/add SSD via 2× M.2 NVMe slots
- Expand storage to 2TB+ easily
RAM Compatibility & Upgrades
DDR4-3200 SO-DIMM (Dual Channel)
GT13 Pro uses 2x DDR4-3200 SO-DIMM slots (laptop form factor) in dual channel, supporting up to 64GB. DDR5 modules will not fit.
Configuration Options
- Factory 16GB: 2x 8GB DDR4-3200
- Factory 32GB: 2x 16GB DDR4-3200

SSD Compatibility & Upgrades
Dual M.2 Slots (NVMe + SATA)
GT13 Pro includes one M.2 2280 PCIe 4.0 NVMe slot and one M.2 2242 SATA slot:
- Factory config: 512GB or 1TB (usually 1 slot populated)
- Second slot empty: Add another drive
- Total capacity: Geekom lists up to 2TB (NVMe) + 1TB (M.2 2242 SATA)
SSD Replacement Steps
- Power down, unplug
- Remove bottom panel
- Locate M.2 slots (typically mid-board)
- Eject existing SSD (push at 30°, release, pull out)
- Insert new NVMe at 30°, press down until seated and screw if needed
- Close panel, boot
Recommended SSD Options
Compatible: Samsung 990 EVO M.2 NVMe, WD Blue SN580, Crucial P3 Plus.
Power Supply & Thermal Design
120W DC Barrel Adapter
GT13 Pro uses a 120W external DC barrel adapter (19V / 6.32A), not USB-C PD. Adequate for sustained multi-threaded workloads. In brief compute bursts (compilation, export), power draw peaks at 60–75W. Under light load: 20–30W.
Active Cooling
GT13 Pro includes a small active fan (unlike passive Mac Mini). Under sustained load, fan noise is audible (~30–35 dB) but not intrusive. Ambient temp tolerance: up to 30°C without thermal throttling.
Connectivity & Display Support
USB4: Two Ports
GT13 Pro has 2x USB4 (40Gbps) Type-C ports. A USB4 or Thunderbolt dock can add further ports if needed.
USB-A & USB-C Abundance
3x USB-A 3.2 Gen 2 and 1x USB-A 2.0, plus the 2x USB4 Type-C ports, provide plenty of wired connectivity without needing a dock. Video output includes 2x HDMI 2.0.
Display Support
Display outputs:
- 2x HDMI 2.0
- 2x USB4 Type-C (display output via USB-C alt mode)
WiFi 6E & Networking
WiFi 6E Performance
802.11ax on 2.4/5/6GHz delivers ~1.2 Gbps peak. Real-world office: 400–600 Mbps. 2.5 Gigabit Ethernet port is included; use for stable LAN connections or NAS access.

Frequently Asked Questions
Is GT13 Pro better than Mac mini M4?
Comparable performance; GT13 Pro excels in upgradeability (64GB RAM, dual SSD slots). M4 is more energy-efficient and compact. Choose GT13 Pro if you need expansion; M4 if sealed simplicity is preferred.
Should I buy 16GB or 32GB factory config?
Start with 16GB; upgrade to 32GB if workload demands. Extra RAM adds to the upfront cost. Most developers work fine on 32GB factory config; upgrade later if needed.
Can I use both M.2 slots simultaneously?
Yes. Add an M.2 2242 SATA SSD to the empty second slot, or replace the existing 512GB NVMe drive with a larger M.2 2280 NVMe drive. The second slot is SATA, so it runs at SATA speed rather than NVMe speed.
What’s the best upgrade path for GT13 Pro?
Factory 16GB + 512GB → add 32GB RAM (£120) + 1TB M.2 2242 SATA SSD in second slot (£60) = £500–600 system with 32GB RAM + 1.5TB storage for ~£680 total.
Are the two USB4 ports limiting?
Not really. The four USB-A ports handle most peripherals, and a USB4 or Thunderbolt dock can add more ports if needed.
