 ## AMD ROCm (Preview)[[rocm]]
 
 * Support for AMD GPUs is currently in a preview state.
-* All features are supported for consumer RDNA devices.
-* The Data Center products currently lack support for the default 4bit blocksize of 64, and as such default to 128.
+* All features are supported for both consumer RDNA devices and Data Center CDNA products.
 * A compatible PyTorch version with AMD ROCm support is required. It is recommended to use the latest stable release. See [PyTorch on ROCm](https://rocm.docs.amd.com/projects/install-on-linux/en/latest/install/3rd-party/pytorch-install.html) for guidance.
