AMD EPYC Rome 7nm Processors Set a New Standard for CPU Performance

The long awaited ‘AMD EPYC Rome’ has finally arrived. Announced August 7th, 2019, AMD’s New 7002 Series server processors have taken the compute world by storm. The 7002s feature up to 64 ‘Zen 2’ cores per SoC, and deliver marked improvements on per-core server workloads over several Benchmarks. This includes: Floating Point Performance, JAVA Performance, Integer Performance, and HPC Workloads.

AMD 7002 Series is First-to-market PCIe 4.0 readiness

The new 7002 series is also the first and only current x86-architecture server processor that supports PCIe 4.06. With this, PCIe 4.0 delivers double the I/O performance over PCIe 3.0. Effectively, you’re allowed 128 lanes of I/O to double the network bandwidth that is the glue of modern HPC clusters.  For application needs and in virtualized environments, this allows the ability to connect with higher speed to GPU accelerators, NVMe drives, and integrated disk controllers.

Best in Class Security, a Key Feature of AMD EPYC Rome Processors

Starting with the 1st Gen AMD EPYC Processors which pioneered a an architecture designed to help defend against side-channel attacks, encryption for main memory and virtual machine memory, and cryptographically help secure the boot process  AMD’s 2nd Gen AMD EPYC Processors bring increased depth and optimization to these features with growing support in the software ecosystem.

2nd Gen EPYC processors helps safeguard privacy and integrity by encrypting each virtual machine with one of up to 509 unique encryption keys known only to the processor. This Secure Encrypted Virtualization (SEV) protects confidentiality of your data even if a malicious virtual machine finds a way into a vm’s memory. In addition to this, it also protects against a compromised hypervisor reaches into a guest vm.

AMD Features Infinity Architecture

AMD also highlighted the ‘Infinity Architecture’, a hybrid multi-die architecture that is central to the new EPYC 7002 Series processors. The Architecture now decouples two streams: 8 dies for the processor cores, and 1 I/O die that supports security and communication outside the processor.

7 Nanometer Silicon Process Takes Center Stage

Additionally, AMD is first to market a x86 processor based on 7 nanometer technology. With double the core density and optimizations that improve instructions per cycle, the result is 4x the Floating-Point performance of previous generation AMD EPYC.

The 7 nanometer process technology also touts it’s energy efficiency. The 2nd Gen AMD EPYC can provide the same performance at half the power consumption.
