20GB 320-Bit GDDR6 for 4K Gaming

This PowerColor Radeon RX 7900 XT delivers 20GB of GDDR6 memory across a 320-bit bus. The GPU runs at a 2000 MHz game clock and can boost to 2400 MHz with 5376 stream processors. A triple-fan cooler keeps the 300W board stable in an ATX build. It targets enthusiasts who need high frame rates at 4K resolution.

Upgrade from 12GB cards

Moving to 20GB adds headroom for texture-heavy titles and multi-monitor workloads. The PCI Express 4.0 interface and modern display outputs (1 x HDMI 2.1, 2 x DisplayPort 2.1, 1 x USB Type-C) replace older I/O clusters. A 750W power supply with two 8-pin connectors is required. The jump is worth it when 12GB buffers become a bottleneck at 4K or in content creation.

20GB capacity and 320-bit bandwidth

The 20GB frame buffer comfortably handles 4K gaming, high-resolution texture packs and four simultaneous displays up to 7680 x 4320. The 320-bit GDDR6 interface sustains throughput for compute tasks and video editing. Limits appear when workloads exceed 20GB VRAM or demand more than 300W thermal headroom in a 2.5-slot, 276 mm form factor.

Questions about this item

Will the 276 mm length and 2.5-slot width fit my ATX case?

The card measures 276 mm long and occupies 2.5 slots, so verify your case has at least that much clearance and that adjacent brackets are free.

Which power connectors must be plugged in for the 300 W TDP?

Two 8-pin PCIe connectors are required; the common mistake is leaving one unseated or using a single daisy-chained cable instead of separate runs from the PSU.

When should the triple-fan cooler be cleaned or thermal paste renewed?

Dust the three fans every few months with compressed air; plan on replacing thermal paste after a couple of years if temperatures climb under load.
