AMD and NVIDIA often release new models or refreshes of their graphics cards at the end of summer or early fall. They have already released new models throughout 2020 and 2021, so refreshes or new variants are expected. Notable leaker GreyMoon55 has been sharing interesting details for both manufacturers. Seventeen new AMD PCI IDs were spotted in a Linux driver that include a number of unknown GPUs.
There are 32 PCI IDs, but 17 of them seem to be new GPU variants. They include: Sienna Cichlid (Navi 21) – 5 new, Navy Flounder (Navi 22) – 5 new, and Dimgrey Cavefish (Navi 23) – 7 new. It is unknown whether any of these will be refreshes, but it is highly probable that some will be. There is also a possibility that at least one of these mystery GPUs could be the unreleased Navi 24.
It was believed that AMD might be refreshing its Navi 22, 23, and 24 GPUs. The latter still has not been released and at this point, it is unclear when should we expect it to launch. Just recently AMD added its Navi 23 GPU to the existing family of products. It is now available for both Radeon consumer and Radeon workstation SKU and their mobile variants.
The patch features not only the Navi 22 and 23 but also Sienna Cichlid which is Navi 21. This GPU was not expected to be refreshed because it is rumored to feature just as many cores as Navi 33 (5120 SPs). This would be an unfortunate decision from a marketing and product segmentation perspective.
