During CES2022, AMD announced a new graphics card for the mobile version of the RX 6000 series using the RDNA 2 architecture, but did not mention the desktop product. According to the news of the @Greymon55, AMD will announce the 50XT enhanced version of the RX 6000 series in June/July this year, that is, the RX 6X50XT product that uses the enhanced version of the RDNA 2 architecture (RDNA 2 Refreshed).
However, recently, according to the news of another channel, AMD may launch the Radeon RX 6X50XT series graphics card in advance, and the Radeon RX 6950XT will meet with us as soon as mid-April. This is at least 2 months ahead of the release time in greymon55 messages.
Also, earlier news suggested that the Radeon RX 6950XT, Radeon RX 6850XT, and Radeon RX 6750XT would be released at the same time, but now it seems that not all Navi 21 SKUs will be updated, and the Radeon RX 6950XT is likely to be the only Navi 21 graphics card to be upgraded.
The Navi 21 is the core used by the Radeon RX 6900 XT, RX 6800 XT, and RX 6800, while the Navi 22 is the core used by the desktop version of the RX 6700 XT. In addition to the process upgrade to TSMC N6, the Radeon RX 6X50XT series will also use faster GDDR6 memory, which will increase the memory speed from 16Gbps to 18Gbps, which will provide higher bandwidth and increase performance by 2-5%.
In addition, the news also said that AMD is developing a new graphics card in the Radeon RX 6000 series, based on the 6nm Navi 24 GPU core, will be named Radeon RX 6500 (non-XT), can only be regarded as a DIY version of the Radeon RX 6400.
Judging from various news, AMD itself is not ready to fully promote the enhanced version of RDNA 2 to radeon RX 6000 series desktop graphics cards, and the RX 6X50XT series is obviously a transitional product before the launch of RX 7000, I believe more users are concerned about when radeon RX 7000 using RDNA 3 will be launched.
