BRIX barebone with Ryzen 7 4800U

The GIGABYTE BRIX GB-BRR7H-4800-BWUS is a barebone mini PC built around an AMD RYZEN R7-4800U processor with 8 cores and 16 threads running at 2.0 GHz base and 4.1 GHz boost. Integrated AMD Radeon graphics operate at 1750 MHz within a 15 W envelope. It targets system builders who want a compact foundation for home, office or digital-signage deployments.

Two SO-DIMM slots and dual M.2 bays

The board provides two 260-pin SO-DIMM slots supporting DDR4 3200 up to 64 GB total, one M.2 2280 slot for storage and one M.2 2230 A-E key slot pre-occupied by an Intel WiFi6 AX200 card delivering WiFi6 and BT 5.2. A 2.5-inch SATA bay accepts 7.0 mm or 9.5 mm drives. No memory or storage is included.

Straightforward assembly

Installing SO-DIMM modules and a 2.5-inch drive requires removing the chassis base; the M.2 2280 slot is accessible in the same step. The WiFi6 AX200 module already occupies the 2230 slot, so builders cannot swap it for a different wireless card without desoldering. Front I/O includes one USB 3.2 Type-C with DP alt mode, three USB 3.2 Type-A ports, a headset jack and the power button.

Questions about this item

Will I need to buy DDR4 SO-DIMM modules separately, and what is the maximum capacity the two slots support?

The barebone ships without memory; you must add two 260-pin DDR4 3200 SO-DIMMs for a total of 64 GB.

What thermal ceiling stops the AMD R7-4800U from holding its 4.1 GHz turbo during long workloads?

The processor is rated at 15 W, so sustained turbo clocks are limited by the cooling solution’s ability to dissipate that power envelope.

How loud does the fan get and how much heat does the 15 W chip produce when the unit runs all day?

The 15 W AMD R7-4800U with Radeon graphics at 1750 MHz generates modest heat; the compact chassis uses a single fan that stays relatively quiet under continuous load.
