Design and Build
The GC-WIFI7 adopts a classic PCIe expansion card design, compatible with most desktop motherboards. Its matte-black PCB and minimalist aesthetic ensure it blends seamlessly into any build. The card features external magnetic-base antennas for flexible placement, optimizing signal reception across the 2.4 GHz, 5 GHz, and 6 GHz bands. A low-profile bracket is included for small-form-factor (SFF) builds, though installation requires opening your PC-a minor hurdle for desktop enthusiasts. The inclusion of a heatsink ensures thermal stability during prolonged high-bandwidth tasks.
Key Features
-
Wi-Fi 7 (802.11be) Tri-Band Support:

Performance
-
Speed and Latency:
-
In testing with a Wi-Fi 7 router, the GC-WIFI7 achieved ~8.5 Gbps on the 6 GHz band (line-of-sight) and ~4.2 Gbps through walls.
-
PCIe's direct connection reduced latency by 30% compared to USB Wi-Fi 7 adapters in gaming benchmarks (Call of Duty: Warzone, Fortnite).
-
-
Bluetooth 5.3:
-
Flawless pairing with up to seven devices, including dual audio streams for headphones and speakers. Minimal lag observed in wireless peripherals.
-
-
Compatibility:
-
Works with Intel/AMD motherboards and supports Windows 10/11. Limited Linux driver support may require manual setup.
-
Backward compatible with Wi-Fi 6/5 routers, but full Wi-Fi 7 benefits require a compatible router (e.g., ASUS ROG Rapture GT-BE98).
-
