Notes on 14 values — test conditions and caveats
  1. 1AMD Radeon RX 7900 XTX, Release date: First retail sale December 13, 2022; announced November 3, 2022.
  2. 2AMD Radeon RX 7900 XTX, Launch price: AMD's launch figure is the SEP (suggested e-commerce price); partner cards often sold higher.
  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. 5NVIDIA GeForce RTX 5080, Recommended PSU: NVIDIA's minimum for a PC with a Ryzen 9 9950X; it recommends a PCIe CEM 5.1 compliant PSU.
  6. 6NVIDIA GeForce RTX 4080 Super, Recommended PSU: NVIDIA's 750 W minimum assumes a PC with a Ryzen 9 5900X; needs vary by configuration.
  7. 7AMD Radeon RX 7900 XTX, Recommended PSU: AMD's 800W minimum assumes a Ryzen 9 5900X-class system; other builds may need more headroom.
  8. 8NVIDIA 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.
  9. 9AMD Radeon RX 7900 XTX, Power connectors: The reference card uses two 8-pin connectors.
  10. 10NVIDIA GeForce RTX 5080, DisplayPort version: DisplayPort 2.1b at UHBR20 on all three DP outputs.
  11. 11AMD Radeon RX 7900 XTX, DisplayPort version: DisplayPort 2.1 runs UHBR 13.5, up to 54Gbps of display link bandwidth per AMD.
  12. 12AMD Radeon RX 7900 XTX, Hardware encode: AMD's spec table marks 4K H264 Encode, H265/HEVC Encode and AV1 Encode all as Yes.
  13. 13AMD Radeon RX 7900 XTX, Video encoders: AMD describes a Dual Media Engine, i.e. two encode/decode engines, capable of simultaneous 8K60 HEVC streams.
  14. 14NVIDIA GeForce RTX 5080, Slot width: The card is 2-slot (40 mm thick), but NVIDIA's install guide asks for 3-slot (61 mm) case clearance.
