About ASRock Radeon RX 7900 XT Phantom Gaming OC 20 GB GDDR6
Introducing the ASRock Radeon RX7900 XT Phantom Gaming OC 20 GB. It is based on AMD’s RDNA 3 Navi 31 GPU and has a powerful 320-bit GDDR6 interface with 20 Gbps bandwidth, 84 compute units (5,376 stream processors), and an 80 MB Infinity Cache. A normal game clock is around 2075 MHz, while its factory OC pushes boost clocks to 2450 MHz.
The Phantom Gaming 3X cooling system, which consists of three striped-ring axial fans, a reinforced heatsink, heatpipes, and a reinforced metal backplate, controls thermals. In idle mode, fans stay off at 0 dB. Fitting into a ~2.8-slot, 330 × 140 × 57.6 mm chassis, it uses about 315 W TBP and is powered by two 8‑pin connectors. Included are 3× DisplayPort 2.1 and 1× HDMI 2.1 outputs, as well as integrated Polychrome SYNC lighting with switchable
