We first learned about such a CPU five years ago
In the summer of 2015, about two years before the first AMD processors on the Zen architecture entered the market, information appeared on the web that the company was developing the Exascale Heterogeneous Processor (EHP) server hybrid processor. There were few details about it, but it was said about 32 cores, a large GPU and HBM2 memory.
AMD has not abandoned the idea of creating a monstrous hybrid processor Exascale Heterogeneous Processor
As we understand, AMD has not released anything like this. The first-generation Epyc server processors really had 32 cores, but now the flagships already contain 64 cores. However, EHP looks impressive even now, because Epyc CPUs have neither a GPU nor their own HBM2 memory.
As it turned out, work on EHP, apparently, is still underway. This is indicated by multiple recent AMD patents. They concern various technological solutions and not the product as a whole, but everything indicates that AMD did not abandon the idea of creating an Exascale Heterogeneous Processor. In addition, the company has partially implemented some of the ideas originally attributed to EHP. For example, it released not only 32-core but also 64-core processors.
In addition, AMD recently talked about X3D technology, which includes the use of a three-dimensional layout when creating new chips. More specifically, X3D implies the simultaneous use of a three-dimensional layout, as well as the layout that AMD calls 2.5D. It was this arrangement that was originally described for the Exascale Heterogeneous Processor. Thus, it is possible that AMD will introduce something similar during the year.
