AMD Introduces ROCm 6.4 with Radeon PRO W7800 Support and Improved Compatibility
AMD has officially released ROCm 6.4, a new version of its open source software stack for computing on GPU and accelerators. An important innovation was the official support of the video card Radeon PRO W7800 48GB, however, support for graphics processors RDNA4 (Radeon RX 9000, GFX12 architecture) remains unofficial for now, despite community confirmations of its functionality. AMD has not made any official comments regarding plans to fully support these GPU, including Strix Halo chips.
Key improvements in ROCm 6.4 include expanded compatibility between ROCm userland software and AMDKFD kernel-level drivers. This now provides greater stability and the ability to run multiple Linux kernel versions. AMD has also expanded internal testing to support more userland and kernel software combinations.
Additionally, ROCm 6.4 now includes support for new versions of PyTorch — 2.5 and 2.6, as well as improvements within the Megatron-LM with new unified cores: Fused Attention (QKV), Fused Layer Norm and Fused ROPE. Support for format decoding has also been added. VP9 in rocDecode and rocPyDecode, including reading a bitstream.
The update brings official compatibility with Oracle Linux 9, a derivative of RHEL9, and includes new modules for the ROCm Data Center Tool. AMD plans to discuss ROCm developments and its AI strategy in more detail at the Advancing AI event in June.
