Days after rumors suggested that AMD would update the Radeon RX 6000 family with faster memories, a forum post chipell reinforced the possibility of the debut of the new plates. Apparently, only three models in the line should receive improvements, thus adopting the nomenclature ending in “50 XT”, similar to what the company did in the notebook variants.
AMD may release new RX 6950 XT and RX 6850 XT
The information was reposted by the leaker Greymon55, responsible for previous rumors, and suggest that AMD would update cards based on the Navi 21 and Navi 22 chips, present in the RX 6900 XT, RX 6800 XT and RX 6800, in addition to the RX 6700 XT. With that, we would see the arrival of three models, which would adopt the new naming convention used by the company in the updated notebook versions: the RX 6950 XT, the RX 6850 XT and the RX 6750 XT.
According to Chipell’s leakers, both Navi21 and Navi22 will be updated.

It is not yet known what changes would be applied in the releases, but it is already speculated that the addition of faster memories would be the main one. With the exception of the liquid-cooled RX 6900 XT and the controversial RX 6500 XT, the current desktop RX 6000 family is based entirely on GDDR6 RAM running at 16 Gbps. The “50 XT” models would thus employ 18 Gbps chips, increasing bandwidth and performance without major changes to the board’s structure.
Another expected change, also based on the recently announced mobile variants, is a modest increase in clocks and, consequently, in consumption. Replying to a user, Greymon55 reveals that he believes that the launch of the updated models is a response to the variants that Nvidia has announced, especially the 12 GB RTX 3080 and the RTX 3090 Ti, something that would make sense, at least from a marketing point of view.
RX 6850M XT could be an indication of gains
One of AMD’s launches during CES 2022, the Radeon RX 6850M XT is the new performance champion of the brand for notebooks, and the main indication that the company really should update the desktop cards. The news arrived as a revision of the RX 6800M with modest improvements, and could also serve as an indication of the performance gain we can expect from the supposed “50 XT” series.
The model is equipped with the same Navi 22 chip as the 6800M, bringing 40 Compute Units (CUs) and 2,560 cores, accompanied by 12 GB of GDDR6 VRAM and 96 MB of Infinity Cache, but it increases the clock by up to 160 MHz, thus reaching the 2463 MHz, and implements 18 Gbps memories, allowing bandwidth to jump from 384 GB/s to 432 GB/s on the same 192-bit interface.
The changes took the GPU’s computational power from 11.7 TFLOPs to 12.6 TFLOPs, a 7% gain, the same increase expected for the card in practice. The “50 XT” family for desktops is believed to be official in Q2 2022, and should remain relevant for a few months if rumors that AMD’s next-generation GPUs will be announced later in the year are confirmed.
