During ISC 2021, Intel has confirmed that Sapphire Rapids will eventually support with high-bandwidth memory (HBM). However, these Sapphire Rapids variants with HBM will not be launching alongside the non-HBM variants.

The Sapphire Rapids variants coming equipped with HBM are codenamed SPR-HBM and will not be vendor-specific. Earlier, I mentioned that the HBM variants will not be launching alongside the non-HBM variants. In the lastest findings from AnandTech, the CPUs supporting HBM will come out in late 2022 which is after the launch of Sapphire Rapids.
