AMD has officially unveiled its RX 7800 XT and RX 7700 XT graphics cards, finally completing the RDNA 3 lineup after announcing its first GPUs in November last year. Both cards aim to target 1440p screens and run games at maximum settings, including ray tracing, above 60fps. It will also support AMD’s exciting new frame generation technologies, which we wrote as a separate article after our hands-on FSR 3 and Fluid Motion Frames at Gamescom.
Both graphics cards use the new Navi 32 GPU. The 7800 XT gets a fully enabled 60CU version with a 256-bit memory bus, 64MB of Infinity Cache and 16GB of GDDR6 running at 19.5Gbps, while the 7700 XT is cut short – but not by much at all. It uses a 54CU design with a 192-bit bus and 48MB of Infinity Cache, supported by 12GB of GDDR6 running at 18Gbps. TDP numbers are very similar as well, at 245 watts versus 263 watts, with the 7700 XT scoring higher to make up for the lower CU complement.
AMD’s performance data looks impressive here, with the RX 7800 XT handling the RTX 4070 and the RX 7700 XT more convincingly with the RTX 4060 Ti. Both cards also run at over 60fps at maximum settings on a handful of recent AAA releases, including The Last of Us Part 1, Star Wars Jedi: Survivor, Hogwarts Legacy, and Call of Duty: Modern Warfare 2.
AMD reports that the 7800 XT outperforms the RTX 4070 by up to 23 percent in Modern Warfare 2, Cyberpunk 2077, and Hogwarts Legacy, while trailing by up to 18 percent in RT titles like Dying Light 2, Marvel’s Spider-Man: Miles Morales, F1 23, and Doom Eternal. . The 7700 XT is relatively more competitive, with a 31 percent lead in MW2 and a loss to the 4060 Ti of just nine percent in Doom Eternal with RT.
The RX 7800 XT is available in AMD’s dual-fan, dual-slot design, as well as third-party designs from partners like ASRock, Asus, Gigabyte, PowerColor, Sapphire, and XFX. The reference model has three DisplayPort 2.1 ports and one HDMI 2.1 port, and takes two eight-pin power inputs. Meanwhile, 7700 XT is only for third party, without reference model.
Both cards offer significantly more VRAM than their direct competitors, with 12GB on the 7700 XT and 16GB on the 7800 XT, which should put them up against some of the unjustifiably VRAM-heavy titles we’ve seen in recent months – especially from high-profile ports. PC from PS5. Based on the current situation of gaming with the latest titles, the 12GB of memory in the 7700 XT should prove particularly effective against the 8GB of the 4060 Ti.

Interestingly, both new GPUs use the microchip (‘MCM’) design seen in the 7900 XT and 7900 XTX, versus the homologous RX 7600, with a 200 mm² (5 nm) graphics compute die (GCD) and a 150 mm² (6 nm) memory cache. (MCD). . The number of transistors is 26.5B for the 7700 XT and 28.1B for the 7800 XT. For context, the 7600 monolithic die contains 13.3 billion transistors, while the 7900 XT and XTX’s Navi 31 MCM have 57.7 billion transistors.
For creators, AV1 encoding/decoding, AMD Noise Cancellation and 2X the performance in Stable Diffusion were mentioned against the 6950 XT in AMD’s offering.

The RX 7800 XT and 7700 XT are scheduled to arrive on September 6th, when they’ll be available from the usual AMD GPU makers. This date is also the release date of Starfield, and given the links that exist between AMD and Bethesda, it’s no surprise that these GPUs also come with a version of Starfield’s Premium Edition.
Of course, we’ll have to test these new graphics cards to see if they fully live up to AMD’s claims. Stay tuned.
