Performance and Compute
Driven by 3,840 shader cores and a boost clock of 2,430 MHz, the card delivers 37.3 TFLOPS of FP32 compute capability. This high compute output ensures smooth frame rates in graphic-heavy tasks and quick processing for rendering applications.
Supporting this performance is a base clock of 1,295 MHz and a last-level cache of 64 MB, helping maintain steady speeds during intensive operations.
Memory and Bandwidth
The RX 7800 XT comes with 16 GB of GDDR6 video memory operating across a 256-bit memory bus width. This configuration delivers a memory bandwidth of 624 GB/s at a memory speed of 19.5 Gbps.
Such generous memory specifications allow users to handle high-resolution textures and complex asset loads without bottlenecks.
Power and System Requirements
Operating at a board power of 263 W, the card requires a single 8-pin power connector for energy delivery. Buyers must pair it with a recommended PSU of 700 W to ensure stable system performance.
It connects via a PCIe 4.0 interface utilizing 16 lanes, fitting modern motherboard slots effortlessly.
Display Connectivity
For monitor connections, the RX 7800 XT provides one HDMI port and three DisplayPort outputs, supporting up to 4 displays simultaneously. The HDMI version is 2.1a according to the press release, while the DisplayPort version is 2.1, with DP 2.1 support depending on AIB designs.
The hardware video engine handles H.264, HEVC, and AV1 encoding for modern streaming and recording needs.
