Notes on 5 values — test conditions and caveats
  1. 1NVIDIA GeForce RTX 5090, Recommended PSU: NVIDIA's minimum for a PC with a Ryzen 9 9950X; it recommends a PCIe CEM 5.1 compliant PSU.
  2. 2AMD Radeon RX 7800 XT, HDMI version: AMD's spec page lists HDMI 2.1; its own press release and Notebookcheck state HDMI 2.1a.
  3. 3NVIDIA GeForce RTX 5090, DisplayPort version: DisplayPort 2.1b at UHBR20 on all three DP outputs.
  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.
  5. 5NVIDIA GeForce RTX 5090, Slot width: The card is 2-slot, but NVIDIA's install guide asks for 3-slot (61 mm) case clearance.
