Intel's new Xeon "Sapphire Rapids" CPU has 4 stacks of 16GB HBM2e memory, for a total of 64GB HBM2e through Xeon Scalable. The new Sapphire Rapids CPUs are built on Intel's new Eagle Stream platform, unlocking up to 56 cores and 112 threads with up to 350W TDPs.

On the GPU side of things Intel is using its new Ponte Vecchio HPC GPU, offering 4MB of L1 cache and 144MB of L2 cache per GPU tile. In total, there is 408MB of L2 cache while the GPU is going to use multiple fabrication notes: Intel 7 for the base tile, TSMC N7 for Xe-Link, and TSMC N5 for the computing tile.

In the detailing of its next-gen Xeon "Sapphire Rapids" CPUs, Intel rolled out a roadmap for its data center products. Intel will be launching a successor to each of the new products debuting in 2022, in 2023 -- but they didn't offer much more detail than "yeah, something next-gen is coming in 2023, obviously".
