Intel L3 does not equal AMD L3 cache regarding latencies. Depending on the application this can matter a lot. https://pics.computerbase.de/7/9/1/0/2/13-1080.348

  You'd need that latency to be significant enough that AMD's >2x core count doesn't still result in it winning by a landslide anyway, and you need L3 usage low enough that it still fits in Intel's relatively tiny L3 size. There's been very few cloud benchmarks where 1P Epyc Rome hasn't beaten any offering from Intel, including 2P configurations. The L3 cache latency hasn't been a significant enough difference to make up the raw CPU count difference, and where L3 does matter the massive amount of it in Rome tends to still be more significant. Which is kinda why Intel is just desperately pointing at a latency measurement slide instead of an application benchmark.
