The Chips and Cheese teardown details eight Accelerator Complex Dies on TSMC N2 plus two I/O dies and two fabric-and-cache dies on N3, twelve HBM4 stacks on 2048-bit buses, 192 channels, 256 Work Group Processors at 2.4GHz for up to 40.26 PFLOPS of OCP MXFP4. The Helios rack pairs four MI455X with one 96-core EPYC 9006 SP7 per compute tray. Here's the number builders can act on: 432GB per GPU means a 1.4TB MXFP4 model fits in four GPUs instead of a rack.
