AMD RDNA 3 Navi 31 'GFX1100', Navi 32 'GFX1102', Navi 33 'GFX1101' Split Screen Core Next 3.2 GPUs, APUs Get DCN 3.1.4

AMD RDNA 3 Navi 31 ‘GFX1100’, Navi 32 ‘GFX1102’, Navi 33 ‘GFX1101’ Split Screen Core Next 3.2 GPUs, APUs Get DCN 3.1.4

3 AMD RDNA GPUs including Navi 31, Navi 32 and Navi 33 and an integrated APU part are listed under the latest Linux patch.

AMD RDNA 3 Navi 31, Navi 32, Navi 33 for DCN 3.2, RDNA 3 APU Gets DCN 3.1.4 Support

So far, a total of four AMD RDNA 3 GPUs have been included in the range Linux patches and the open source LLVN repository† Among them are Navi 31 ‘GFX1100’, Navi 32 ‘GFX1102’, Navi 33 ‘GFX1101’ and GFX1103 appearing as APUs, so the version used is likely to be in the range of the upcoming Phoenix Point APU. Details have been collected dream koalakanth And it looks like we have new information about which versions of DCN or Display Core Next each chip will support at launch.

For the discrete RDNA 3 GPU set that includes the AMD Navi 31, Navi 32 and Navi 33 GPU, the red team will upgrade from the current DCN 3.0 engine to the new DCN 3.2.1 engine. On the other hand, the APU does not use the same version as the discrete RDNA 3 GPU family. It has the same chain as the current RDNA 2 ‘GFX1030’ APU series called DCN 3.1.4 series. AMD Sabrina APU uses DCN 3.1.6 engine.

In terms of features, both the DCN 3.2 and DCN 3.1 series seem to come with support for four display-only outputs. This was the standard for RDNA 2 GPUs and will be maintained in the RDNA 3 series as well. Additional information states that there is now support for MALL (Last Level Memory Access) or Infinity Cache for RDNA 3/GFX11 GPUs, so don’t expect Infinity cache to be created on Phoenix Point APUs.

AMD Phoenix Point APUs It’s expected to carry up to 24 compute units or twice as many cores as current Rembrandt APUs, so it’s going to be a huge leap in graphics performance for an integrated chip that it’ll compete with. Intel Meteor Lake chips This holds up to 192 EU’s in a tiled GPU design. Meanwhile, the AMD RDNA 3 GPU Assortment It will be a worthy contender for NVIDIA’s next-generation Ada Lovelace products, which are expected to be unveiled later this year.
