AMD Says Zen 3 7nm+ EPYC Milan CPUs To Offer Better Performance Than Intel Xeon 10nm Chips
Taking to the stage of HPE Cast 2019, AMD has unveiled fresh new insight into its upcoming workstation and server-specific 7nm+ Zen 3 EPYC processors.
Known internally as ‘Milan,’ these third-generation CPUs are primed to oust the Intel equivalent Xeon processors based on 10nm and 14nm++ tech, both of the Ice Lake-SP and Cooper Lake variety. The salient point being an improved performance per watt rating than Intel’s chips.
Many of the aspects of the recently announced Zen 2 EPYC processors, dubbed ‘Rome,’ are set to feature in the Milan chips, most notably a significant boost to the core and thread count.
AMD did say it is looking to up the performance per watt features of the Milan by introducing 20% more transistors than the Rome CPU and 10% improved efficiency thanks to 7nm+ technology.
What We Know
From what we understand, the first iteration of the Milan CPU will be used in the Perlmutter Exascale supercomputer with specifications tentatively revolving around a 64 core and 128 thread setup with 8-channel DDR support with a hefty 256 GB per node and AVX2 SIMD.
The Milan looks set to rival Intel’s well-publicized Ice Lake-SP and the purported headline-grabbing IPC boost of 18% that did the rounds this summer. As always, AMD will offer this upped performance at a lower price point than Intel, further entrenching AMD’s position as a viable alternative to Intel in the server CPU landscape.
AMD has plans to launch the EPYC Milan in 2020, although it didn’t provide a more precise release window than that. Moving forward AMD is working on a Zen 4 chip, codenamed Genoa, which should see the light of day before 2022 going by AMD’s recently updated 2019-2022 roadmap.
