Upcoming AMD CPU with RDNA1 Graphics May Go For Sale Found In Linux Code

Rumor mill: AMD appears to be preparing another APU (accelerated processor) in line with the driver code found in Linux 5.15 release, although it appears to be using an integrated GPU based on RDNA1 rather than the second generation coming with new products.

Graphics driver fixes reported Phoronix Friday appears to be referring to a graphics processor codenamed Cyan Sailfish. The APU can target consumer or embedded applications, although the first generation RDNA architecture is perhaps the most surprising aspect of this. The last few generations of these integrated graphics processors (up to the Ryzen 5000 APUs on both mobile and desktop) have continued to use the AMD Vega architecture since 2017, albeit with various updates over the years.

However, according to leaks compiled in the frequently cited roadmap below, the next major APUs from AMD are moving to RDNA2 rather than first-generation Navi graphics. On the other hand, it is also likely that the architecture will be tweaked and improved over earlier implementations such as the RX 5700 XT, as AMD’s current Vega integrated offerings are very different from their arrival in the Ryzen 2000G.

No CPUs with either of the two RDNA architectures have been officially released or announced yet other than the current generation consoles, so we can only speculate about the final APU. However, it may very well be just an entry-level product for embedded applications like the current Ryzen V-series chip line, as the smaller RDNA1 die should lower manufacturing costs and the device types using them won’t need high performance.

Cyan Skillfish could also find its way into laptops or other mobile products, but that’s unlikely as Valve’s upcoming Steam Deck already proves that high-performance graphics in a portable form factor very an attractive offer for many.
