AMD releases ACP “Audio Driver” code for Ryzen 7000 “Raphael” processors

AMD has released new open-source Linux driver code to enable the Audio Coprocessor (ACP) on the upcoming Ryzen 7000 “Raphael” desktop processors.

AMD releases new ACP driver code for Raphael “Ryzen 7000” processors

Although this new code enabling the audio coprocessor of the Raphael platform which will soon be released is excellent for preparations for the next Linux kernel, it happens to be released quite late. As we move closer to the full launch of the new AMD Ryzen 7000 series desktop processors, using the Zen4 architecture, this new ACP audio driver was crucial for the integration of upcoming chips.

New AMD Ryzen 7000 processors are expected to deliver significant generational performance per watt and frequency boost, up to 10% instructions per clock boost, 15% single-thread performance gain and 125% bandwidth memory bandwidth per core. The new processors will offer the ISA extension for artificial intelligence and AVX-512.

AMD Ryzen 7000 processors will launch on September 15. 3D V-Cache chips could arrive later in November or December, while Intel’s Raptor Lake is expected around October 2022.

While AMD doesn’t offer a huge IPC boost over Zen 4, the higher clocks and the addition of V-Cache may put AMD in the higher sections of gaming performance compared to the Raptor Lake d series. ‘Intel. AMD’s 3D V-Cache technology can outperform Intel and its increased internal cache that will be available in Intel’s Raptor Lake processors.

Fixes for the SoC ACP Linux driver and several new header files were added to the five patches today for Raphael Open Source Support (RPL). The Linux 5.20 merge window will appear in over a week. It is therefore unclear whether AMD could have added this crucial integration later due to the immediacy of the release. However, the next chance AMD had to add support to Linux would not have happened until the next generation of the Linux kernel, version 6.0.

Michael Larabel of Phoronix points out that late release in kernel may result in no ACP audio support at launch. More integrations will be available for the new AMD Zen 4 desktop processor support, which will monitor temperatures and a few other last-minute additions.
