Alleged AMD EPYC Milan “Zen 3” CPU Engineering Sample CPU-z Spotted, Single-Core Performance Reportedly On Par With Top Xeon CPUs
Alleged AMD EPYC Milan “Zen 3” CPU Engineering Sample CPU-z Spotted, Single-Core Performance Reportedly On Par With Top Xeon CPUs-April 2024
Apr 1, 2026 10:30 AM

Alleged pictures and information regarding AMD's next-generation EPYC Milan CPUs have been published YuuKi_AnS (ViaHarukaze5719). The leaker who has previously posted leaked a range of tech products has now started talking about AMD's Zen 3 processors and based on what he has stated, he's talking about the EPYC Milan lineup which starts shipping this year.

Alleged AMD EPYC Milan CPU Sample Spotted, Expected To Feature Single-Core Performance On Par With Top Intel Xeon CPUs

The CPU-z screenshot isn't very detailed and only shows a partial section of the number of cores. It looks like the chip features more than 8 cores. The actual core amount is unknown but it looks like the chip could feature more than 32 cores based on how long the scroll bar is. This could be one of the first engineering samples of the Zen 3 based EPYC Milan CPU that we are looking at. The leaker also reports on some specific performance numbers of the chip.

According to Yuuki, the next-generation AMD EPYC Milan CPUs will feature single-core performance on par with Intel's top of the line Xeon CPUs. The leaker reports a benchmark score of at least 500 points. Again, no specific details are provided as to which benchmark suite was used to obtain the numbers but if the leaker is referring to the CPU-z benchmark, then we are looking at a 23% jump in performance over the 2nd Generation Rome based EPYC 7742 CPU.

For Cinebench R20, this will represent a performance jump of 25-30% in single-threaded workloads which is a significant boost. This falls in line with recent rumors which stated that EPYC Milan CPUs can feature around a 20% performance improvement over its predecessors.

The performance metrics being compared to Xeon also makes it very likely that this is an EPYC Milan based chip that has been pictured in the CPU-z screenshot and not a mainstream consumer chip. It is also stated that this chip was running on a dual-socket (2P) platform which is expected of a top-tier EPYC chip. If the performance metrics are true, then AMD will not only be taking its multi-threaded lead to new heights but with its single-core performance, AMD will also displace Intel as the new 1T performance and efficiency king in the server market.
