AMD’s Yellow Carp GPUs float in Linux Driver Driver


AMD has begun enabling driver support for its possibly new GPU, which is based on the RDNA series architecture and features the company’s next generation DCN 3.1 display controller. Whether the new “Yellow Carp” GPUs are high-end, midrange or low-end graphics solutions is currently unclear, but we have some ideas.

AMD’s post about its Yellow Carp GPU (first noticed by Phoronix) states that the GPU is actually an ASIC (i.e., a standalone GPU). Meanwhile, another AMD entry in a Linux repository shows that Yellow Carp is actually a family of GPUs that includes Yellow Carp and Green Sardine, an integrated GPU set to be used for upcoming Accelerated Processing Units (APUs).

The current speculations about the water cooler assume that Yellow Carp will come onto the market in the Rembrandt APUs. The main features of the GPUs from Yellow Carp and Green Sardine (which continue AMD’s “fishy traditions”) are said to be an RDNA series graphics architecture and AMD’s next generation Display Core Next 3.1 (DCN 3.1) engine. AMD’s RDNA2-based standalone Radeon RX 6000 series has the DCN 3.0 engine, but the difference between version 3.0 and 3.1 is unknown.

AMD has been using its Polaris / Vega-based GPUs (originally introduced in 2016) in its APUs for years. These APUs offer pretty decent gaming performance and capabilities, but their media decode / encode capabilities are half a decade old for its upcoming Van Gogh and Rembrandt Accelerated Processing Unit (APU). Yellow Carp could be just what the doctor ordered for these integrated graphics processors.

As with all unreleased products, AMD has not commented on the emergence of Yellow Carp, but with the GPUs already flowing into Linux drivers, we can expect more details to come out soon.
