AMD EPYC 7003 Series Processors (Milan)
28 December 2022

    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.
    Milan CPUs use innovative security technologies:
    The previously known AMD Infinity Guard is supplemented with Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP) technology - isolating the running environment, and strengthening the protection of memory and its integrity, preventing attacks.

    • 7313 – budget.  The highly demanded CPU received 16 cores and 32 threads, respectively, with a base and maximum frequency of 3/3.7 GHz. Equipped with 128 MB L3 cache and very low-heat dissipation of 155W.

    AMD Epyc Processor

    The processor market turned upside down with the release of the first generation of AMD EPYC, at that time AMD became the industry leader, but the company did not stop there and continued to improve the development.
    The best server processors are becoming even more powerful and quickly occupying the corporate segment.
    The Milan series is another breakthrough in the server industry, high speed and computing power make them true leaders in sales.
