These new graphics cards are based on the world’s first chiplet GPU, and offer some impressive specifications including 24 GB of 384-bit GDDR6 (not GDDR6X) on the flagship XTX model – with 20 GB of 320-bit GDDR6 on the XT model (one fewer memory chiplet enabled).
The flagship XTX part has 96 CUs, a 2.3 GHz Game Clock, 24 GB 384-bit GDDR6, and a rated 355W TBP (total board power). The XT part has 84 CUs, a 2.0 GHz Game Clock, 20 GB 320-bit GDDR6, and a lower 300W TBP. AMD is also, as previously stated by Scott Herkelman, using standard 8-pin PCIe connectors for these cards. Oh, and speaking of PCIe, these are PCI Express 4.0 devices.
