AMD will debut TSMC's ambitious System-on-Integrated-Chips (SoIC) technology with its upcoming HPC chips, according to a DigiTimes report. A step toward rivaling Intel's Foveros 3-D chip stacking technology, SoIC will enable AMD to stack logic, memory, and I/O as separate chips within a single package. The article references a next-generation "HPC" chip, although it didn't delve into what this could be. Logically, AMD would want to integrate its EPYC and MI accelerator lines into a single package that can be used in HPCs. Such a product would combine its Zen-series x86-64 serial processing, with CDNA-series scalar processing, expertise in memory, leveraging large on-die victim-caches, and high-bandwidth memory (HBM); along with next-gen I/O.
 
Combining everything into one stream-lined package looks very promising.
