However, if you're a graphics card nerd, this is exciting stuff because the new Mac Pro modules utilize AMD's Radeon Pro W6000 series workstation GPUs, which were just released in June. Specifically, Apple customers can now order Mac Pro graphics modules packing new Radeon Pro W6800X or Radeon Pro W6900X cards, each with 32 GB of DDR6 RAM. There's also a third option, the Radeon Pro W6800X Duo, which pairs two Pro W6800X GPUs in the same module (bridged by AMD's Infinity Fabric Link tech) for extra power. If you really want to go all out, you can order a pair of the W6800X Duo modules (a $9,600 upgrade) and all four AMD cards will work together (via Infinity Fabric Link) to churn out high-res assets or support multiple 4K displays.
