AMD EPYC Bergamo CPU Die Detailed: 16 Zen 4C “Vindhya” Cores Per CCD & 35% Smaller Core Area

wccftech.com:

More details of AMD's upcoming EPYC Bergamo CPUs which will be powered by the new Zen 4C Dense cores have been revealed by Semianalysis.

The AMD EPYC Bergamo CPU lineup is expected to launch next week at the “AMD Data Center and AI Technology Premiere" where the company is going to talk about its server, cloud, and AI product families. AMD will go into detail for multiple products which include the first products based on the Zen 4C or any Zen-Dense design, Bergamo. Being part of the same EPYC 9004 family, the Bergamo chips might look similar but inside their heart, they are a very different kind of beast that target a very specific set of applications.

The main competition of AMD's EPYC Bergamo is the various Arm & compute-density optimized chips coming from Intel such as Sierra Forest which is going to feature up to 144 E-Cores. Intel's solution won't be out till the first half of 2024 and that is if everything goes according to plan for Intel 4 (process node). This will also be targeted as the competitor to NVIDIA's Grace which relies purely on Arm cores and among a dozen of other Arm-based chips that are becoming a common household in major tech data centers.

So what we already know about AMD's EPYC Bergamo CPUs is that they will feature up to 128 cores based on the Zen 4C cores which are fabricated on TSMC's 4nm process node which can be seen as a slight improvement over the 5nm process node which powers the Zen 4 cores at the moment. It's going to offer up to 256 threads so multi-threading is there whereas that's not the case with Intel's E-Cores, it supports 12-channel DDR5 memory, PCIe Gen 5.0 functionality, & is drop-in compatible with the existing SP5 socket with no software port required since the same Zen 4 ISA
