PowerColor RX7800XT 16G-E/OC/LIMITED graphics card

PowerColor RED DEVIL 16GB Radeon RX 7800 XT

This refurbished graphics card targets gamers and creators who need 16GB GDDR6 on a 256-bit bus for 1440p and entry 4K workloads. The AMD RDNA 3 GPU delivers 3840 stream processors with a 2169 MHz core clock and 2565 MHz boost clock. It fits ATX builds with a 345 mm length and 2.5-slot width.

Upgrade from 12GB cards

Moving from a 12GB model adds 4GB VRAM and the 256-bit interface, which helps with high-resolution textures and multi-monitor setups. The PCI Express 4.0 x16 link and 263W TDP require an 800W power supply. The jump makes sense when current VRAM limits frame rates or forces texture quality reductions.

PCI Express 4.0 x16 bandwidth limits

The card runs on a PCIe 4.0 x16 slot, so systems limited to PCIe 3.0 will halve theoretical throughput. DisplayPort 2.1 and HDMI 2.1 outputs support 7680 x 4320 resolution across four displays. The 256-bit memory bus and GDDR6 memory cap peak bandwidth, which can become a bottleneck in memory-heavy 4K scenarios.
