As rumored earlier, both the Radeon RX 7800 XT and the Radeon RX 7700 XT are based on the RDNA3 architecture Navi 32 GPU.
The Radeon RX 7800 XT targets the Nvidia Geforce RTX 4070 12GB graphics card, promising 60+ average FPS at native 1440p and maximum settings. The Radeon RX 7800 XT maxes out the Navi 32 GPU, packing 60 compute units (CUs), for a total of 3,840 Stream processors, 120 AI accelerators, 60 Ray accelerators, and 64MB of Infinity Cache.
It comes with 16GB of 19.5Gbps GDDR6 memory on a 256-bit memory interface, resulting in 624GB/s of memory bandwidth. The TDP is set at 263W and it needs two 8-pin PCIe power connectors. The GPU works at 2124MHz Game and 2430MHz Boost clocks, but we expect some custom cards to push those clocks a bit higher.
The Radeon RX 7700 XT uses the same Navi 32 GPU but cut down to 54 CUs, leaving it with 3,456 Stream processors, 108 AI accelerators, 54 Ray accelerators, and 48MB of Infinity Cache. It also comes with 12GB of slightly slower 18Gbps GDDR6 memory on a 192-bit memory interface, pulling the maximum memory bandwidth down to 432GB/s. The GPU works at 2171MHz Game and 2544MHz Boost clocks and the TDP is set at 245W, which means it still needs two 8-pin PCIe power connectors.
The Radeon RX 7700 XT targets the Nvidia Geforce RTX 4060 Ti 16GB graphics card, and, according to AMD, should still be enough for 60+ average FPS at native 1440p resolution and max settings.
AMD has launched decent performance-segment/mid-range graphics cards, at least on paper, but let us wait for some reviews to hit the net before we draw any conclusions.
At $499 and $449, these are decent graphics cards. With a promise of FSR 3 Fluid Motion, which will be available on previous Radeon RX series graphics cards, HYPR-RX, that should integrate all of AMD's important technologies in a simple one-button solution, and pretty good bundles, new AMD graphics cards could be quite popular.
