As for the benchmarks, AMD pitted a 2P (dual-socket) EPYC system against a 2P Intel Xeon Platinum 8280 system, the former with 128 total cores and 256 threads, and the latter with 56 total cores ...

The Xeon Platinum 8280 is a 28-core Cascade Lake CPU (Cascade Lake). It isn't particularly surprising that AMD's 128 core configuration turns in more than 2x the performance of the Intel system.

The Xeon Platinum 8280 is 28C/56T, 2.7GHz base, 4GHz boost, and a 205W TDP, ... In HEVC, the performance figures change. Here, Intel and AMD are at parity overall, ...

New benchmarks for AMD’s upcoming 64-core Threadripper 3990X CPU apparently show it outperforming Intel’s much more expensive Xeon Platinum 8280 processors. We certainly have high hopes for ...

But here's the thing, each Xeon Platinum 8280 CPU costs around $10,000. In other words, the Threadripper 3990X is outperforming $20,000 worth of Xeon silicon in this particular benchmark.

There are effectively no publicly accessible benchmarks available for newer Xeons like the 8380HL—and they aren't any faster than the Xeon Platinum 8280 anyway, even using Intel's own numbers ...

Comparing the performance of the 40C80T Xeon Platinum 8380 to the last-gen 28C56T Xeon Platinum 8280, one would expect a healthy lead for the newer platform by virtue of more cores and higher IPC.
