The dual GPUs are connected to each other onboard using Infinity Fabric Link. The most interesting top-end card, AMD's Radeon Pro W6800X Duo MPX Module, is a multi-GPU solution with up to 30.2 teraflops of FP32 compute and 60.4 teraflops of FP16 performance. Apple's entry level MPX module is the AMD Radeon Pro 580X (Polaris) and currently described as 'perfect for non-GPU-intensive applications'.Ībove, you can see the tech specs of the new trio of graphics card options available to Apple Mac Pro users / buyers. Previously, Mac Pro 'MPX Module' upgrades plateaued at the Radeon Pro W5700X (a version of the RX 5700 XT). The new AMD Radeon Pro W6000X series graphics cards are all based upon Navi 21 silicon – as used by the consumer-facing Radeon RX 6800, RX 6800 XT and RX 6900 XT.
Specifically, Apple is offering a trio of RDNA2 architecture GPU graphics card configuration options – with the top option being a dual-GPU card with at total of 120CUs and 64GB of GDDR6 memory. The extra graphical grunt comes to these workstation machines, usually dedicated to graphics- and compute-intensive apps, courtesy of the new AMD Radeon PRO W6000X Series GPUs. Apple is updating (PDF link) its Intel CPU-based Mac Pro line of computers with new high-end GPU upgrade options.
