AMD has formally unveiled its RX 7800 XT and RX 7700 XT graphics playing cards, lastly finishing its RDNA 3 lineup after asserting its first GPUs in November final 12 months. Each playing cards are meant to focus on 1440p shows and run video games at max settings, together with ray tracing, above 60fps. They will additionally assist AMD’s thrilling new body era applied sciences, which we have written up as a separate article after going hands-on with FSR 3 and Fluid Movement Frames at Gamescom.
Each graphics playing cards use the brand new Navi 32 GPU. The 7800 XT will get the fully-enabled 60CU model with a 256-bit reminiscence bus, 64MB of Infinity Cache and 16GB of GDDR6 reminiscence operating at 19.5Gbps, whereas the 7700 XT is cut-down – however not by a lot in any respect. It makes use of a 54CU design with a 192-bit bus and 48MB of Infinity Cache, backed with 12GB of GDDR6 operating at 18Gbps. TDP figures are additionally very comparable, at 245W vs 263W, with the 7700 XT clocked increased to make up for its decrease CU complement.
AMD’s efficiency knowledge appears spectacular right here, with the RX 7800 XT buying and selling blows with the RTX 4070 and the RX 7700 XT extra convincingly coping with the RTX 4060 Ti. Each playing cards are additionally proven exceeding 60fps at max settings in a bunch of current AAA releases, together with The Final of Us Half 1, Star Wars Jedi: Survivor, Hogwarts Legacy and Name of Obligation: Trendy Warfare 2.
AMD factors to leads for the 7800 XT towards the RTX 4070 by as much as 23 p.c in Trendy Warfare 2, Cyberpunk 2077 and Hogwarts Legacy, whereas being as much as 18 p.c behind in RT titles equivalent to Dying Mild 2, Marvel’s Spider Man: Miles Morales, F1 23 and Doom Everlasting. The 7700 XT is comparatively extra aggressive, with as much as a 31 p.c lead in MW2 and solely shedding to the 4060 Ti by 9 p.c in Doom Everlasting with RT.
The RX 7800 XT is offered in an AMD reference dual-fan, dual-slot design, along with third-party designs from companions equivalent to ASRock, Asus, Gigabyte, PowerColor, Sapphire and XFX. The reference mannequin has three DisplayPort 2.1 ports and one HDMI 2.1 port, and takes two eight-pin energy inputs. In the meantime, the 7700 XT is third-party solely, with no reference mannequin.
Each playing cards supply noticeably extra VRAM than their direct rivals, with 12GB on the 7700 XT and 16GB on the 7800 XT, which ought to inure them towards a number of the unjustifiably VRAM-heavy titles we have seen in current months – significantly from high-profile PC ports from PS5. Primarily based on the present state of play with the newest titles, the 12GB of reminiscence within the 7700 XT ought to show significantly efficient up towards the 8GB 4060 Ti.

Apparently, each of the brand new GPUs use the chiplet (‘MCM’) design seen within the 7900 XT and 7900 XTX, versus the monolithic RX 7600, with a 200mm² 5nm graphics compute die (GCD) and 150mm² 6nm reminiscence cache die (MCD). Transistor counts are 26.5B for 7700 XT and 28.1B for 7800 XT. For context, the 7600’s monolithic die has 13.3B transistors, whereas the 7900 XT and XTX’s Navi 31 MCM die has 57.7B transistors.
For creators, AV1 encoding/decoding, AMD noise supression and doubled efficiency in Steady Diffusion vs the 6950 XT had been all talked about in AMD’s presentation.

The RX 7800 XT and 7700 XT are set to reach on September sixth, the place they will be out there from the standard AMD GPU makers. That date can also be the Starfield launch date, and given the prevailing hyperlinks between AMD and Bethesda it is unsurprising that these GPUs additionally include a duplicate of Starfield’s Premium Version.
In fact, we’ll have to check these new graphics playing cards to see whether or not they absolutely reside as much as AMD’s claims. Keep tuned.
