Notes on 4 values — test conditions and caveats
  1. 1NVIDIA GeForce RTX 4080 Super, Recommended PSU: NVIDIA's 750 W minimum assumes a PC with a Ryzen 9 5900X; needs vary by configuration.
  2. 2NVIDIA GeForce RTX 4080 Super, Power connectors: Card takes a 16-pin 12V-2x6 connector; a 3x PCIe 8-pin adapter ships in the box for PSUs without a PCIe Gen 5 cable.
  3. 3AMD Radeon RX 7800 XT, HDMI version: AMD's spec page lists HDMI 2.1; its own press release and Notebookcheck state HDMI 2.1a.
  4. 4AMD Radeon RX 7800 XT, DisplayPort version: Notebookcheck lists the DisplayPort 2.1 link rate as UHBR13.5; AMD notes DP 2.1 support depends on AIB designs.

Price and Value

The AMD Radeon RX 7800 XT undercuts the competition significantly with a launch price of $499. By comparison, the NVIDIA GeForce RTX 4080 Super costs 999 USD.

Buyers on a tighter budget will find the AMD card much easier to justify, while the NVIDIA option targets enthusiasts willing to pay double for higher-tier components.

Performance and Power

The NVIDIA GeForce RTX 4080 Super leads with 10,240 shader cores and 52 TFLOPS of FP32 compute. This raw horsepower translates to faster rendering speeds in demanding applications.

To feed that performance, the NVIDIA card requires a 320 W board power and a 750 W recommended PSU using a 12V-2x6 connector. The AMD Radeon RX 7800 XT draws less power at 263 W and needs a 700 W power supply with an 8-pin connector.
