  3. 3AMD Radeon RX 7900 XTX, Boost clock: Boost is a burst maximum; typical gaming runs near the 2300 MHz game clock.
  4. 4AMD Radeon RX 7900 XTX, Memory bandwidth: AMD also quotes 3500 GB/s 'effective' bandwidth with Infinity Cache; 960 GB/s is the raw VRAM figure.
  5. 5AMD Radeon RX 7900 XTX, Recommended PSU: AMD's 800W minimum assumes a Ryzen 9 5900X-class system; other builds may need more headroom.
  6. 6AMD Radeon RX 7900 XTX, Power connectors: The reference card uses two 8-pin connectors.
  7. 7Intel Arc B580, DisplayPort version: Intel rates the DisplayPort outputs at DP 2.1 up to UHBR 13.5 (second output listed at UHBR 10).
  8. 8AMD Radeon RX 7900 XTX, DisplayPort version: DisplayPort 2.1 runs UHBR 13.5, up to 54Gbps of display link bandwidth per AMD.
  9. 9Intel Arc B580, Hardware encode: Intel's spec table also lists H.264 and H.265 (HEVC) hardware encode as Yes.
  10. 10AMD Radeon RX 7900 XTX, Hardware encode: AMD's spec table marks 4K H264 Encode, H265/HEVC Encode and AV1 Encode all as Yes.
  11. 11AMD Radeon RX 7900 XTX, Video encoders: AMD describes a Dual Media Engine, i.e. two encode/decode engines, capable of simultaneous 8K60 HEVC streams.
  12. 12Intel Arc B580, Card height: Intel publishes this dimension as the card's 'Width' (115 mm) alongside the 272 mm length.
