ThinkSystem SR665 Sets 2 World Records with New SPECompG Benchmark ResultPerformance Benchmark Result
The Lenovo ThinkSystem SR665 server has set two new 2-socket performance world records with the SPECompG_base2012 and SPECompG_peak2012 metrics of the SPEC OMP2012 Benchmark. The SPEComp Benchmark suite is the industry standard to evaluate performance using applications based on the OpenMP 3.1 standard for shared-memory parallel processing.
This document summarizes the the SPECompG benchmark result for the ThinkSystem SR665 that was published on March 15, 2021. The document lists the result, summarizes the major components of the configuration under test, and provides the link to the relevant benchmark organization’s web site for details about the result.
The Lenovo ThinkSystem SR665 server has set two new 2-socket performance world records with the SPECompG_base2012 and SPECompG_peak2012 metrics of the SPEC OMP2012 Benchmark.
The SPEC OMP2012 Benchmark suite is the industry standard to evaluate performance using applications based on the OpenMP 3.1 standard for shared-memory parallel processing and includes 14 scientific and engineering application codes, covering everything from computational fluid dynamics (CFD) to molecular modeling to image manipulation.
The ThinkSystem SR665 has achieved the following scores:
- SPECompG_base2012 = 44.7
- SPECompG_peak2012 = 45.2
This result is the best 2-socket performance in the industry.
The SR665 was configured as follows for the benchmark audit:
- 2x AMD EPYC 7763 processors (64 cores, 2.45GHz)
- 1TB memory (32x 32GB RDIMMs, 3200MHz)
- ThinkSystem 1 TB SATA HDD
- Red Hat Enterprise Linux 8.3, Kernel 4.18.0-240.el8.x86_64t
Results referenced are current as of March 15, 2021.

About the ThinkSystem SR665
The Lenovo ThinkSystem SR665 server, now with AMD EPYC 7003 Series processors, delivers outstanding TCO for transactional database, ERP, virtualization, big data & analytics and software-defined deployments. The combination of two AMD EPYC 7003 CPUs with class-leading memory speed, storage, and GPU density, rapidly outpaces the power of prior generation two-socket servers. Lenovo’s lauded system reliability, management capabilities, and security infrastructure layer on to the exceptional value that the ThinkSystem SR665 brings to the data center. With the enterprise-class AMD EPYC 7003 Series or 7002 Series processor, the world’s first 7nm data center CPU, the ThinkSystem SR665 features two processors with up to an unprecedented 128 total cores with 128 PCIe Gen4 lanes to reduce bottlenecks and increase server utilization.
Compared to the previous processor generations, ThinkSystem SR665 delivers up to 2X performance and 4X floating point capability, providing faster data transfer and analytics without sacrificing memory capacity or I/O with PCIe Gen4 support and faster memory speeds up to 3200 MHz.
- 128 cores across two processors to handle heavy-lift ERP, CRM, and virtualization workloads; provides cutting edge application efficiency in health care applications such as medical imaging, EMR, and PACS, or electronic trading platforms for financial services applications.
- Multi-GPU optimized rack server, providing support for up to 8 single-wide GPUs that offer 200% more workload acceleration in AI Inference, and virtualized desktop infrastructure (VDI).
- Support for up to 32 NVMe solid-state drives; when paired with high speed networking, make the system an excellent choice for workloads that need large amounts of low-latency high-bandwidth storage, including virtualized clustered SAN solutions, software-defined storage (SDS), and applications leveraging NVMe over Fabrics.
About SPEC OMP2012
The SPEC OMP benchmark is designed for measuring performance using applications based on the OpenMP 3.1 standard for shared-memory parallel processing. The benchmark also includes an optional metric which includes power measurement.
The benchmark includes 14 scientific and engineering application codes, covering everything from computational fluid dynamics (CFD) to molecular modeling to image manipulation. The optional energy consumption measurements are based on the SPEC Power and Performance Benchmark Methodology, which provides details on how to integrate a power metric into standardized benchmarks.
SPEC OMP focuses on compute intensive performance, which means an emphasis of the performance of the following hardware and software:
- Memory architecture
