Structure of the processors
The latest generation AMD EPYC™ 7002 uses AMD Infinity Architecture, a multi-die concept that delivers high performance. AMD Infinity processors consist of two main parts – 8 dies, each with eight processor cores (CCDs, produced by 7nm technology) and one I/O die (IOD) that provides security and communication beyond the processor.
First-to-market PCIe Gen 4 readiness
AMD EPYCs are currently the only x86 server processors that support PCI-E 4.0, delivering twice the performance of PCI-E 3.0. As a result, they offer up to 128 I/O lines and are thus able to double the bandwidth to connect to an HPC cluster. For other application needs and in virtualized environments, you can connect at higher speeds to GPU accelerators, NVMe drives, and even use integrated disk controllers to access disks without a typical PCIe RAID controller.
Comparison of AMD EPYC 7002 an 7003 series with its previous generation
As indicated above, these are the first server processors with x86 architecture that are built on 7nm technology. Thus, the EPYC 7002 and 7003 series CPUs use 7nm for the CPU cores themselves and 14nm for I/O (memory access and CPU security functions). At the same time, this new generation delivers up to 2.2x higher performance and up to 4x in theoretical FLOPS, compared to the previous generation of CPUs. Other advantages of the new AMD processors include improved security architecture – Secure Root-of-Trust Technology, Secure Memory Encryption (SME) or Secure Encrypted Virtualization (SEV).

What does the next generation of processors bring?
Changes from the 7002 generation of the third generation AMD EPYC Milan include a higher performance jump of up to 25% for the most common 16-core processor and up to 15% for multi-core CPUs (48, 64 cores).
The new generation of AMD EPYC 7003 also brings changes in the L3 cache, the biggest advantages include:
2 × L3 cache directly accessible to the core
Up to 32MB of memory per core, which can be allocated to one active core
Improved performance in applications, where more cache memory is required
Reduction of memory latency
Better performance for virtual servers
As further changes, the AMD EPYC 7003 brings:
Zen 3 architecture, which brings increased performance to the core
Enhanced security features
Support for 4 configurations, newly 6 and 8 memory channels
Infinity FabricTN and Memory Clock Synchronized technologies that provide improved memory performance
We have prepared a detailed comparison of current processor architectures – Intel Xeon, AMD EPYC, IBM POWER, or ARM. In the article you will find tables with the parameters of each processor and also the advantages of their deployment for a specific type of applications.
Processors with AMD 3D V-Cache™
The new AMD EPYC™ 7003 processors with AMD 3D V-Cache™ are built on groundbreaking AMD 3D Chiplet architecture, which uses 7nm technology. These processors then use stacking (silicon-on-silicon) and thus boast up to 200× higher throughput than existing 2D CPUs and more than 15× higher throughput than other CPUs using 3D technology.
