Combo Purpose

This bundle pairs a Radeon RX 9070 XT graphics card with an AMD X870E flagship motherboard. Both components share the PhantomLink rear-plug power system for cleaner cable routing. The set targets builders who want a matched high-end GPU and platform foundation for AMD AM5 processors.

Sustained Load Behaviour

The graphics card runs at a game clock up to 2520 MHz and a boost clock up to 3060 MHz across 4096 stream processors. Memory operates at 20000 MHz on a 256-bit GDDR6 interface. The motherboard delivers power through a 16+2+1 phase design rated at 90A per phase and supports DDR5 memory overclocking beyond 8400 MT/s.

Build and Connectors

The GPU includes two HDMI and two DisplayPort 2.1a outputs driving up to 7680 x 4320 resolution across four monitors. The motherboard provides dual rear USB4 40G ports, a front USB-C 20G header, four M.2 slots with two PCIe 5.0 links, Wi-Fi 7, Bluetooth 5, and 5G wired networking. Quick-release cooling armor and onboard control buttons simplify maintenance.
