The AMD E-450 dual-core APU comes clocked at 1.65 GHz (which combines two Bobcat architecture x86-64 cores) with a Radeon HD 6320. The Radeon HD 6320 has a base clock of 508 MHz but goes to 600 MHz in Turbo mode and is DirectX 11 compliant. It is capable of a max resolution of 1920 x 1080 @ 60 Hz (HDMI / DVI) and 2560 x 1600 @ 60 Hz (RGB). The board measures 9.6" by 7.2".
The board features two DDR3-1333 MHz integrated memory slots in single-channel mode, which is capable of DDR3 1600 (OC). The board is powered by a standard 24-pin and 4-pin 12V ATX power to host one PCIe 2.0 x16 (operates at x4 mode), one PCIe 2.0 x1, and two PCI slots. A large heatsink keeps the APU and Hudson M1 chips cool during use, within an optional CPU fan. Storage needs are managed through five SATA 6 Gb/s internal ports and one eSATA 6 Gb/s.
In addition, E45M1-M PRO features Realtek ALC887 8-Channel HD audio, two USB 3.0 ports (back panel), gigabit Ethernet, Firewire, and twelve USB 2.0 ports (4 on back panel and 4 internal headers supporting two USB 2.0). The board is driven by UEFI BIOS, including Asus' EZ-Mode GUI setup program.
