At Gamescom 2023, AMD has officially announced the forthcoming arrival of the RX 7700 XT and RX 7800 XT. As a reminder, AMD already has four models in its range featuring the new RDNA3 architecture. We recently reviewed the RX 7600 and previously the RX 7900 XT and RX 7900 XTX. These two new AMD models are here to compete with NVIDIA’s RTX 4070 and RTX 4060 Ti.
Two cards for 1440p definition:
AMD is clear on this point, confirming that gamers have chosen 1440p definition as their new playground. The RX 7700 XT and RX 7800 XT are the latest additions to this graphics card segment. The RX 7600 is aimed at 1080p, and the two RX 7900 XT and RX 7900 XTX at 2160p.
The idea is to offer two cards capable of delivering at least 60 FPS in 1440p definition. As we said, on the slides provided by AMD, the RX 7700 XT is compared to the NVIDIA RTX 4060 Ti 16 GB and the RX 7800 XT to the RTX 4070.
In terms of performance, AMD claims that the RX 7800 XT will outperform the RTX 4070 by an average of 3.5% in 1440p games at maximum settings. Some titles even show an advantage of 5% to 23%. In the same selection of titles and graphics settings, the RX 7700 XT would be 12% faster on average than the RTX 4060 Ti 16GB. We’ll be assessing the differences between the various models in our test, not forgetting to evaluate raytracing and the contribution of DLSS and FSR.
Technical specifications :
The RX 7800 XT uses the entire GPU chip named Navi 32 XT, with 60 CU, 128 AI Accelerators, 16 GB GDDR6 memory clocked at 19.5 Gbps on a 256-bit bus. The card will therefore offer fewer cores than the last-generation RX 6800 XT (72 CU). The GPU ‘s clock speed will reach 2430 MHz, and power consumption is announced at 263 watts.
On the RX 7700 XT side, the specifications are also very interesting and higher than we expected. The Navi 32 XL chip is slightly neutered and uses 54 CU and 108 AI Accelerators. This is a significant evolution on the previous generation, the RX 6700 XT with its 40 CU. This model also uses 12 GB of GDDR6 memory on a 192-bit bus, although the memory clock is slightly lower, at 18 Gbps. The RX 7700 XT has a higher power consumption than the RX 6700 XT, with an increase of 15 W to 245 W.
Although we know that the cards will be available in September 2023, no price has yet been announced. The RX 7800 XT should be available as a reference version, as shown in the photos on the slides, while the RX 7700 XT will only be offered as a custom model by AMD’s partners.
AMD FSR 3 and AMD HYPR-RX:
While no date has yet been set, we should be seeing the arrival of FSR 3 (FidelityFX Super Resolution) and HYPR-RX technology very soon. We hope that AMD will announce the arrival of these two technologies at the same time as the launch of the two new cards, although nothing has yet been confirmed at the time of writing. As a reminder, FidelityFX Super Resolution is an upscaling technology that increases FPS.
The slides are very interesting, however, since as with NVIDIA’s DLSS 3, the gains in terms of FPS are very interesting. AMD has also announced the compatibility of Forspoken with DLSS 3. We’ll be adding this game to our comparative tests from now on. The list of games compatible with the FSR 3 will of course grow in the future.
As far as AMD HYPR-RX is concerned, we should have an equivalent to the NVIDIA Reflex. Although once again AMD has provided screenshots in its slides, no information concerning the arrival of this technology has been mentioned. In any case, we can’t wait to review these two models and judge the contribution of these upcoming technologies!
