The new Radeon Pro Vega II and Radeon Pro Vega II Duo graphics cards are not for gamers in any shape, way or form -- they are pure workhorses that are perfect for professionals that need crazy amounts of GPU horsepower. Tasks like video editing native 8K resolution content, rendering, and other compute-intensive tasks the Vega 20 GPU on 7nm with 32GB of HBM2 per GPU is up to the task.

Each of the Radeon VII Pro Vega II graphics cards are quad-slot cards, because they're passively cooled with a unique cooling system deployed by Apple into the new Mac Pro. The new Radeon Pro Vega II has 14.2 TFLOPs of FP32 performance and 28.4 TFLOPs of FP16 performance while the Radeon Pro Vega II Duo dual-GPU card has 28.4 TFLOPs and 56.8 TFLOPs, respectively. The single card solution has 32GB of HBM2 while the dual-GPU solution rocks 64GB.

In the new Mac Pro they can be used in 4-way GPU setups so there's a total of 4 x Vega 20 GPUs on 7nm with 128GB of total HBM2 memory at your disposal all at 1TB/sec across its 4096-bit memory bus. The GPUs are connected through AMD's own Infinity Fabric, with 84GB/sec of bandwidth through the Infinity Fabric link.

This does require Apple's own proprietary Mac Pro Expansion Module (MPX Module) which will allow for the dual Radeon Pro Vega II or dual Radeon Pro Vega II Duo graphics cards. This is when you'll get your up to 128GB HBM2 and 4-way GPU craziness with Infinity Fabric handling inter-GPU communications.

We also have an all-new PCIe connector being used on the Apple Mac Pro, providing up to a huge 475W of power per card.
