AMD has introduced two highly anticipated graphics cards: RX 7800 XT and RX 7700 XT, filling a crucial gap in AMD’s RDNA3 lineup of desktops.
For this release, AMD introduced a new GPU called the Navi 32. Although previously shown, this marks its first implementation in a gaming series. The Navi 32 GPU features up to 60 compute units and a 256-bit memory bus, accompanied by 64MB of Infinity Cache.
The RX 7800 XT uses the full configuration of this GPU, with 60 CUs, 128 AI accelerators, and 16GB of 19.5Gbps GDDR6 memory on a 256-bit bus. Therefore, the card will offer fewer cores than the last generation RX 6800 XT (72 CU). The GPU clock speed reaches up to 2430 MHz and consumes 263 W of power.
Interestingly, the specifications of the RX 7700 XT exceed expectations. It employs 54 CUs and 108 AI accelerators, a marked improvement over the previous generation RX 6700 XT with its 40 CUs. This model also uses 12 GB of GDDR6 memory on a 192-bit bus, although its memory clock is slightly lower at 18 Gbps. In particular, the RX 7700 XT shows a higher TBP compared to the RX 6700 XT, increasing from 15 W to 245 W.
When it comes to performance, AMD claims that the RX 7800 XT will, on average, outperform the GeForce RTX 4070 by 3.5% in 1440p gaming at max settings. Some titles even demonstrate a 5-23% advantage, though certain games that use ray tracing favor the RTX 4070. In the same selection of titles and graphics settings, the RX 7700 XT is reportedly 12% faster in average compared to GeForce RTX 4060. 16GB Ti card.
AMD confirms that there will be no reference model for the RX 7700 XT, although a render is available for marketing purposes. Only the RX 7800 XT will launch with the new dual-fan cooler, while the RX 7700 XT will be available exclusively through AIB partners. Additionally, AMD confirms that both the RX 7800 XT and RX 7700 XT will support DisplayPort 2.1.
AMD RX 7800 XT will launch at $499 in the US. The RX 7700 XT will cost $449. Both cards will be available on September 6.
