Haha 😂
AMD: "Check out our new 768MB L3 cache on our server CPUs"
Intel: "Hold my beer..."

?? What does hbm have to do with l3 cache?

I should clarify, my post was more about the timing of Intel's announcement. Not the tech.

Intel also unveiled the 408MB L2 cache for Ponte Vecchio. No big announcement like AMD's V2 cache, but delivering it in the same timeframe.

Technically like the article said the HBM can operate in "cache mode", functioning like a cache of the system. Assuming all 48GB of HBM it can function like an extension of L3 or even L4 cache

AMD claims 10% access time penalty compared to on chip L3 cache. I think HBM access times would be signficantly greater so it could be L4 like cache. Nonetheless, it will be interesting to see how much this can speed up certain applications - blockchain mining anyone? 😣
