AMD has announced its much anticipated mid-range offerings in the Radeon RX 7000 series of graphics cards. The RX 7800 XT and RX 7700 XT were unveiled today at Gamescom 2023 and will be available starting September 6.
The 7800 XT and 7700 XT are based on the same RDNA3 architecture as other RX 7000 series graphics card. Both cards are based on a new Navi 32 GPU, which uses a chiplet design similar to the Navi 31 on the RX 7900 XT and 7900 XTX but different to the monolithic design of the Navi 33 on the RX 7600.
Radeon RX 7800 XT
The 7800 XT features 60 compute units and ray accelerators, which is a 29% reduction compared to the 7900 XT. The ROPs (render output units) see a much more significant 50% drop to 96. Game clock has seen an increase from 2000MHz to 2124MHz.
Memory also sees some reductions, with the 20GB 20Gbps GDDR6 on the 7900 XT reduced to 16GB 19.5Gbps on the 7800 XT. Memory bus sees a reduction from 320-bit to 256-bit, with bandwidth dropping from 800GB/s to 624GB/s. The Infinity Cache capacity also drops from 80MB to 64MB.
The 7800 XT has a typical board power of 263W. The card will feature HDMI 2.1 48Gbps and DisplayPort 2.1 54Gbps connectors with support for AV1 decoding and encoding.
The 7800 XT is priced at $499 and will compete against the $599 Nvidia GeForce RTX 4070. AMD claims the 7800 XT is on average 4% faster at 1440p. The 7800 XT also has 33% more memory than the 4070 with a wider memory bus but the 4070 is also a 186W graphics card, making it significantly more efficient than the 7800 XT.
Radeon RX 7700 XT
The 7700 XT is a surprisingly small step down from the 7800 XT, at least as far as the GPU is concerned. It packs 54 compute units and ray accelerators and the same 96 ROPs. Game clock is a slightly higher 2171MHz.
The 7700 XT has 12GB of GDDR6 memory with 18Gbps memory speed, 192-bit bus, and 432GB/s bandwidth. Infinity cache is 48MB. Considering the specs, the 245W board power is also not too far off the 7800 XT’s.
The 7700 XT is only $50 cheaper at $449 and will only be available from board partners. It will compete against the RTX 4060 Ti 16GB, which is priced at $499. AMD claims a far more substantial 12% performance advantage over the Nvidia card for the 7700 XT but since it’s only $50 cheaper you may as well get the 7800 XT.
AMD FidelityFX Super Resolution 3
AMD also revealed additional details of its upcoming FSR3 technology, which is AMD’s version of Nvidia’s DLSS3. FSR3 includes frame generation technology, which AMD calls Fluid Motion Frames and can nearly double your frame rate. This, combined with super resolution upscaling, can provide near tripling of frame rates in titles such as Forspoken. AMD will also be introducing Anti-Lag+, which is a driver based feature to reduce latency.
FSR3 will be compatible with Radeon 5000, 6000, and 7000 series graphics cards, although AMD recommends using on 6000 and 7000 series cards for the best results. The technology will also work with Nvidia cards, with AMD claiming support for 20-series, 30-series, and 40-series cards although the last two will provide best results. No word on compatibility with older cards or cards from Intel.
There is still no word from AMD on when this feature will actually be available to users. The company has stated that Immortals of Aveum and Forspoken will be the first two titles to support the feature with confirmed support for ten additional titles, including Cyberpunk 2077, Avatar: Frontiers of Pandora, and Black Myth: Wukong. Oddly enough, Starfield is not one of the supported titles.
