A few weeks ago, AMD revealed the details of the Ryzen series processors 5000, based on the Zen 3 architecture. Even during the first show, we were offered a short teaser of the capabilities of the top Radeon graphics card based on the NAVI core 21 and using the RDNA 2 architecture. In recent weeks there have been various reports regarding the possible specifications and performance of Radeon graphics cards RX 6000 in Radeon RX characters 6800 , Radeon RX 6800 XT and Radeon RX 6900 XT. Finally, the day of the public presentation of the new RDNA 2 architecture, which was to completely break with the old GCN, was finally here. We were supposed to get a big leap in efficiency with a noticeably higher energy efficiency. How are the new cards from AMD actually looking and will they compete with the NVIDIA Ampere chips?

During the official conference, AMD revealed the details of Radeon RX graphics cards 6800, Radeon RX 6800 XT and Radeon RX 6900 XT, based on the NAVI core 21 and RDNA Architecture 2.

The new graphics cards will be based on a significantly redesigned RDNA 2 architecture. One of the most important novelties is the Infinity Cache, whose task is to noticeably increase bandwidth compared to typical, 384 – bit memory bus. Another feature is AMD Smart Access Memory which, in conjunction with Rade Mode (overclocking with one button in a dedicated application) and AMD Ryzen series processor 5000 gives you an additional performance boost. The first graphics card presented is the Radeon RX 6800 XT, whose performance in 4K and Quad HD is to be comparable or higher compared to GeForce RTX 3080

Titles such as Borderlands 3, Forza Horizon 4, The Division 2, Battlefield V, Call of Duty: Modern Warfare, DOOM Eternal and Shadow of the Tomb Raider were selected for comparison. Radeon RX card 6800 XT comes with 72 Compute Units of the next generation, 128 MB Infinity Cache and 16 GB of GDDR6 VRAM. The total TBP of the entire card is 300 W, so about 20 Less compared to GeForce RTX 3080. Of course, the card uses the 7nm TSMC process, which, thanks to further improvements, managed to obtain 30% faster core clock compared to the previous generation Radeon RX 3090. AMD Radeon RX 6800 XT will be available from 18 November Included 649 dollars .

The second presented card is Radeon RX 6800 with 60 CU blocks. The new GPU will also come with 16 GB of GDDR6 VRAM and 128 MB of Infinity Cache. Total Radeon RX TGP 6000 equals 250 W. During the presentation, AMD compared the card to the NVIDIA GeForce RTX 2080 Ti, that is de facto RTX 2250. The card is supposed to offer higher performance in the same games as presented above. Radeon RX 6800 will available from 18 November for a price of 579 dollars . At the very end, there is an absolute top in the form of the Radeon RX 6800 XT, based on full NAVI core 21 with 80 Compute Units.

AMD compares top RDNA 2 card to NVIDIA GeForce RTX 3090. The GPU has also been equipped with 16 GB of GDDR6 VRAM on the bus 256 – bitwise in combination with 128 MB Infinity Cache, which is supposed to have a noticeable impact on bandwidth also at higher resolutions. Interestingly, the total TBP (Total Board Power) is 300 W, the same as in the Radeon RX 6800 XT. The card also has a high core clock soaring to 2015 MHz in Game mode and 2250 MHz in Turbo mode. According to AMD, in games such as Battlefield V, Borderlands 3, Forza Horizon 4 and Gears of War 5, the Radeon RX card 6900 XT will perform better than GeForce RTX 3090. It is important, however, that the discussed results are related to the active techniques of Rage Mode and Smart Access Memory. Radeon RX Premiere 6900 XT will be held on December 8 for the price 999 dollars. Interestingly, during the presentation, AMD did not really focus on the topic of Ray Tracing. We know RDNA 2 architecture offers hardware support, but no details have been shared about the DXR acceleration units.
