AMD EPYC 7003 Series Processors (Milan)

The AMD EPYC 7003 series (Milan) server processor line has been designed for large-scale projects, database servers, large number of virtual machines, server clusters and institutions with high traffic and increased computing load. In this series, there are 19 processor models, 8-64/16-128 cores/threads. The line is made based on the innovative Zen-3, and a modern technological process in 7 nanometers.

Performance boost

With the new architecture, the performance gain has also increased:

1. Increase in CPU energy efficiency 24%;
2. 24% performance increase (when compared to the 7002 line);
3. Improving the efficiency of work in multithreaded mode;
4. The number of instructions executed has increased by as much as 19%;
5. Bus clock increased to 2 GHz;
6. The indicator of maximum write and read speed has noticeably increased;
7. Latency between cache memory and cores has been reduced.

The manufacturer stated that all parameters have improved performance to a level not available to third-party manufacturers. Server processors from AMD EPYC Zen-3, 280% higher than other manufacturers.

EPYC Milan processor specifications:

• All Zen-3 models are capable of 8-channel operation with ECC-enabled DDR4 modules, and 3200MHz sticks.
• Requirements for the cooling system (TDP) from a minimum of 155 watts. In the top model EPYC 7763, the heat dissipation of the processor is 280 W.
• All Milan models use up to PCI Express 4.0
• Several units use 256 MB L3 cache.
