Notes on 10 values — test conditions and caveats
  1. 1AMD Radeon RX 7700 XT, Base clock: AMD publishes only Game (2171 MHz) and Boost clocks; no base clock appears on AMD's page.
  2. 2AMD Radeon RX 7700 XT, Memory bandwidth: AMD also lists 1995 GB/s 'effective' bandwidth including Infinity Cache; 432 GB/s is the raw VRAM figure.
  3. 3AMD Radeon RX 7700 XT, Recommended PSU: AMD bases this rating on a Ryzen 9 7950X system; your needs may differ.
  4. 4AMD Radeon RX 7700 XT, Power connectors: Reference card uses two 8-pin PCIe power connectors.
  5. 5AMD Radeon RX 7800 XT, HDMI version: AMD's spec page lists HDMI 2.1; its own press release and Notebookcheck state HDMI 2.1a.
  6. 6Intel Arc B580, DisplayPort version: Intel rates the DisplayPort outputs at DP 2.1 up to UHBR 13.5 (second output listed at UHBR 10).
  7. 7AMD Radeon RX 7700 XT, DisplayPort version: Notebookcheck specifies the DP 2.1 output at UHBR13.5 link rate.
  8. 8AMD 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.
  9. 9Intel Arc B580, Hardware encode: Intel's spec table also lists H.264 and H.265 (HEVC) hardware encode as Yes.
  10. 10Intel Arc B580, Card height: Intel publishes this dimension as the card's 'Width' (115 mm) alongside the 272 mm length.
