AMD EPYC 7003: Zen 3 server CPU

AMD EPYC 7003

AMD announced the new EPYC 7003 server processors based on the 7-nanometer Zen 3 architecture. The series consists of 19 models with up to 64 cores. The Californian company has again chosen the name of an Italian city (Milan) to indicate the third generation EPYC CPUs, after Naples (EPYC 7001) and Rome (EPYC 7002).

AMD EPYC 7003 : specifications and prices

The EPYC 7003 series shares many features with the Ryzen 5000 processors, being based on the same architecture, but there are important differences due to the usage target. EPYC 7003 CPUs support dual socket configurations, Infinity Fabric technology and new security features.

The top of the range is EPYC 7763 with 64 cores / 128 threads, base frequency of 2.45 GHz and maximum of 3 , 5 GHz, 256 MB L3 cache and 280 Watt TDP. The other models are listed in the following table:



Common features are support for 128 PCI Express 4.0 lanes, eight channels of DDR4-3200 memory (up to 4TB) and SP3 socket . The main architectural novelty compared to the previous generation is represented by the layout of the cores. The eight cores of each chiplet are connected and can access 32 MB of L3 cache. In the EPYC 7002 there is a 32 MB block for each four cores.



The four F models (the letter can be read in the name) offer a higher frequency per single core and are therefore optimized for software that does not support a large number of cores.

In addition to the security features found in the EPYC 7002, AMD has added the new SEV-SNP (Secure Encrypted Virtualization-Secure Nested Paging) which protects the integrity of the memory, blocking hyervisor-based attacks.

Microsoft, AMD partner on confidential computing features powered by AMD Epyc 7003 processors

Microsoft has been providing confidential computing capabilities for Azure for several years. The main benefit: To encrypt data while it's in use, which is especially important to customers in the finance, government, health care and communications verticals. To date, most, if not all of Microsoft's confidential computing work has centered around Intel hardware. But that's about to change.


On March 15, Microsoft announced it would be extending its confidential computing options in partnership with AMD -- the same day AMD took the wraps off its newest Epyc chip.


Microsoft announced today it would become the first major cloud maker to offer confidential virtual machines on the newly announced AMD Epyc 7003 series processors. Key to that work is the security feature called Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP), which enables protection of VMs by creating a trusted execution environment and which will be 'substantially enhanced' in the third-generation AMD Epyc processor, Microsoft's blog post says.


In other AMD Epyc news today, Microsoft also announced availability plans for AMD Epyc 7003-powered Azure virtual machines, which will be optimized for high-performance-computing (HPC) workloads.
