Challenger D 8G for 1080p gaming

The ASRock Radeon RX 6600 Challenger D is a PCI Express 4.0 graphics card built on the RDNA 2 architecture. It carries 1792 stream processors, 8GB of GDDR6 memory on a 128-bit bus and runs at a game clock of 2044 MHz with a boost clock of 2491 MHz. The card suits gamers targeting 1080p resolution with a thermal design power of 132W.

Check PSU and case clearance

Verify that your power supply delivers at least 500W and provides an 8-pin PCIe power connector for the card. The board occupies two expansion slots and measures 269 mm in length, so confirm the available space inside your chassis before ordering. A PCI Express 4.0 slot is required for full interface bandwidth.

Dual-fan cooler and four display outputs

A black dual-fan cooler handles the 132W thermal load in a compact two-slot form factor. The rear bracket offers one HDMI 2.1 port and three DisplayPort 1.4 connectors, enabling up to four simultaneous displays at a maximum resolution of 7680 x 4320. HDCP support is included for protected content playback.
