The ASRock barebone mini PC is a compact desktop built around an AMD Ryzen 5 processor, rather than a fully configured, ready-to-use computer. Its processor has 6 cores and 12 threads, providing multiple processing threads for applications running at the same time. The specified base frequency is 3.5 GHz; a maximum boost frequency of 4.9 GHz gives the processor a higher clock ceiling than its base rating. This barebone format is intended for buyers who will complete the system with compatible components before putting it into service.
The small-form-factor chassis suits deployments where a conventional desktop would occupy too much space. Intended uses include everyday office work and home computing, as well as digital signage. Support for up to 96 GB of memory sets the upper limit for RAM capacity, rather than indicating an installed amount. Compatible memory and storage must be installed before the computer can be used.
Key Features:- AMD Radeon 760M integrated graphics provide the system's graphics capability.
- Two HDMI outputs provide connections for displays.
- Two RJ-45 Ethernet ports provide wired network connections.
- Two USB 2.0 ports provide connections for compatible peripherals.
- Black chassis provides a neutral exterior finish.
