    AMD RDNA 3 Navi 31 ‘GFX1100’, Navi 32 ‘GFX1102’, Navi 33 ‘GFX1101’ Discrete GPUs To Feature Display Core Next 3.2, APUs Get DCN 3.1.4

    AMD’s RDNA 3 GPUs including Navi 31, Navi 32, Navi 33, and an integrated APU part have been listed within the latest Linux patch.

    So far, a total of four AMD RDNA 3 GPUs have been listed in various Linux patches and the LLVN open-source repository. These include the Navi 31 ‘GFX1100’, Navi 32 ‘GFX1102’, Navi 33 ‘GFX1101’, and the GFX1103 which shows up as an APU so probably the version used within the upcoming Phoenix Point APU lineup. The details were gathered coelacanth-dream and it looks like we have new information regarding the DCN or Display Core Next versions that each chip will support on launch.

    For the discrete RDNA 3 GPU lineup which includes the AMD Navi 31, Navi 32, and Navi 33 GPUs, the red team will be upgrading from the existing DCN 3.0 engine to the new DCN 3.2.1 engine. The APU, on the other hand, doesn’t utilize the same version as the discrete RDNA 3 GPU family. It has the same series which is currently used by the existing RDNA 2 ‘GFX1030’ APU series labeled as the DCN 3.1.4 series. The AMD Sabrina APU uses the DCN 3.1.6 engine.

    In terms of features, it looks like both DCN 3.2 and DCN 3.1 series come with support for just four display outputs. This has been the standard for RDNA 2 GPUs and will be retained for the RDNA 3 lineup too. Additional information shows that there’s now MALL (Memory Access at Last Level) or Infinity Cache support for the RDNA 3 / GFX11 GPU so don’t expect to see Infinity Cache designs on Phoenix Point APUs.

    The AMD Phoenix Point APUs are expected to carry up to 24 Compute Units or double to amount of cores compared to the existing Rembrandt APUs so that’s going to be a huge jump in graphics performance for an integrated chip which will be competing against Intel’s Meteor Lake chips that pack up to 192 EUs in a tiled-GPU design. Meanwhile, the AMD RDNA 3 GPU lineup is shaping up to be a worthy competitor against NVIDIA’s next-gen Ada Lovelace products which are expected to be unveiled later this year.
