  • Testing seems to confirm AMD RX 5700 compatibility.

A report today suggests that Apple has added support for AMD's Radeon RX 5700 to macOS Catalina with the release of 10.15.1 beta 2. According to AppleInsider:

Apple issued the second macOS Catalina 10.15.1 developer beta on Thursday, with the release notes advising of changes to its graphics card support. According to the notes, support has been added for the AMD Navi RDNA architecture, used in the company's newest graphics cards.

Posts made to the egpu.io enthusiast forums reveal the support includes recognition for the RX 5700 XT, via an external graphics card enclosure. In one user's case, the card was recognized in Bootcamp in Windows 10, but had to install the Windows driver for the card as it wasn't available as part of the Windows installation.

This has since been confirmed by AppleInsider testing, with a Sapphire AMD RX5700 card working in a Mantiz MZ-02 eGPU, the Sonnet eGFX Breakaway Box 650, and a Razer Core X enclosure.

The news seems to indicate that users will be able to use the RX 5700 via an external graphics card enclosure. Due to the way compatibility works with eGPUs in macOS, there's no 'plug-and-play' option, with users being limited only to cards supported by macOS.

As AppleInsider notes, this news is a good indication that other RDNA cards may get support going forward.

The latest support for the RX 5700 XT is a good sign other cards using RDNA will be supported in the operating system soon. RDNA cards are 7-nanometer-based GPUs with a refined graphics pipeline that utilizes a multi-level cache to minimize bottlenecks, support GDDR6 memory, and PCIe 4.0.

RDNA-based cards feature in Apple's new Mac Pro, with options to include the Radeon Pro Vega II and Vega II Duo available to users. This latest compatibility update should give Apple some hands on experience with the combination prior to the launch of the Mac Pro.
