AMD’s mysterious “Van Gogh” APU is expected to provide a number of major improvements over its predecessors, among which the graphics core based on RDNA 2 and DDR5/LPDDR5 may be the most important advances. It now appears that the new APU will also have a new audio processing block.
AMD has Post 12 patches for the Advanced Linux Sound Architecture (ALSA) driver to support the upcoming Van Gogh APU, report FronixThe patch shows that Van Gogh will use AMD’s new audio co-processor-ACP 5.x-with two I2S interfaces/controllers. Since there is no mention of AMD’s ACP 5.x blocks that we can find before, it seems that Van Gogh APU will be the company’s first platform to support new audio technologies (at least on Linux).
There is very little information about AMD’s ACP on the Internet. As of press time, the only thing we found is that AMD’s 2017 Raven Ridge APU relies on ACP3x, so maybe AMD’s contemporary APU has ACP4x. It is not clear what kind of innovation ACP 5.x brings (for example, hardware decoding of Dolby Atmos or DTS:X streams?), but we know that it is newer than its predecessors.
AMD’s Van Gogh is indeed one of the most mysterious APUs in the company’s history.The processor is rumor Features Zen 2 core, RDNA 2 based graphics processor and memory controller Support DDR5 and/or LPDDR5 memory. In addition, the chip is expected to be produced using a 7nm process technology from TSMC, which also explains why AMD chose to combine the relatively compact Zen 2 core and high-performance RDNA 2 GPU.
In architecture, Van Gogh will be similar to the custom SoC in Microsoft’s Xbox Series X|S and Sony’s PlayStation 5 console, but without knowing the exact configuration of Van Gogh, we can’t say that this is specifically for gamers APU.
AMD does not comment on unreleased products, so basically everything we know about Van Gogh comes from Linux patches and rumors. So consume everything with a grain of salt.
