This is going to be bad news for Intel in datacenter business. The new Epyc chips based on Zen 4 seem to be so good that the 9374F that has 32 cores, priced at $4850 easily beats Intel's 40 core Xeon 8380 that cost almost double. At the same time, the new chips are lot more efficient. With Intel facing architecural issues with Sapphire Rapids, this looks to be the best time for AMD to pull massive datacenter market share from Intel.
  • 14% IPC uplift.
  • 40% less area in datacenter for same performance, compared to competition.
  • 48% more power efficient.
  • 96 cores, 12 CCDs.
  • 4MB L2 cache per core.
  • 2.4GHz base and 3.7GHz boost clock for top end 9654/P.
  • Up to 400W TDP.
  • 12 channel DDR5 ECC up to 4800MHz and up to 256GB per DIMM.
  • PCIe Gen 5 with up to 160 lanes in 2P configuration.

  • AVX-512 support.
  • 5nm fab for CCDs and 6nm for I/O die.
The end result:

AMD was already pulling away last generation, this just sets the new benchmark now. Intel has been making bad xeons for a while now. Meanwhile amd epyc and even threadripper have been really good.
