Sapphire’s reference Radeon RX 7900 XTX & RX 7900 XT graphics cards listed at Amazon

Sapphire has become AMD’s first AIB partner to list its Radeon RX 7900 series graphics cards, which include the 7900 XTX and the 7900 XT. Both graphics cards are reference models, so the details for both are already known regarding their cooling designs and specs, but the AIB is also working on some really high-end custom designs, such as the Nitro+ and Vapor-X series that have been teased.

The following are the product links at Amazon, but note that both graphics cards are currently listed as unavailable as the launch is in 10 days:

AMD Radeon RX 7900 XTX 24 GB graphics card “official” specs

The AMD Radeon RX 7900 XTX graphics card uses the full Navi 31 XTX GPU with a total of 48 WGPs, 96 CUs and 6144 cores. The core clock for the graphics card is maintained at 2.3 GHz base clock and 2.5 GHz boost clock, providing up to 61 TFLOPs of compute performance at a 355 W TBP.

  • AMD Navi 31XTX: 6144 cores, 384-bit bus, 192 MB infinite cache, 308 mm2 GPU Die @5nm
  • AMD Navi 21XTX: 5120 cores, 384-bit bus, 128 MB infinite cache, 520 mm2 GPU Die @7nm

The AMD Radeon RX 7900 XTX graphics card will also feature 6 MCDs with 16MB of Infinity Cache per chip and 96MB in total over a 384-bit wide bus interface. The card has a VRAM capacity of 20 GB and has 20 Gbps chips that provide up to 960 GB/s bandwidth (3.5 TB/s with Infinity Cache).

AMD Radeon RX 7900 XT 20 GB graphics card “official” specs

There will also be a slimmed-down variant with the Navi 31 XT GPU core. This chip will contain 42 WGPs (84 Compute Units) or 5376 cores and will be used on the Radeon RX 7900 XT graphics card. That is 12.5% ​​fewer cores than the full-fat variant. The GPU also runs at slightly lower clock speeds with a game clock of just 2.0 GHz, which is 300 MHz slower than the XTX variant, and a 100 MHz lower boost clock of 2.4 GHz at a TBP of 300W.

  • AMD Navi 31 XT: 5376 cores, 320-bit bus, 160 MB infinite cache, 308 mm2 GPU Die @5nm
  • AMD Navi 21 XT: 4608 cores, 256-bit bus, 128 MB infinite cache, 520 mm2 GPU Die @7nm

The Radeon RX 7900 XT graphics card will also feature 20 GB of GDDR6 memory via a 320-bit wide bus interface. Since only 5 MCDs are enabled, the card gains 80 MB Infinity Cache, which is 16 MB lower than the top variant and a decrease of 16.6%. The card offers 800 GB/s of bandwidth (3.5 TB/s with Infinity Cache).

Availability AMD Radeon RX 7900 “RDNA 3” graphics cards

The AMD Radeon RX 7900 XTX 24 GB and Radeon RX 7900 XT 20 GB graphics cards will be available December 13 for prices of $999 US and $899 US, respectively.
