ThinkSystem SR655 Sets World Record with New 1-Socket SPECompG ResultPerformance Benchmark Result
The Lenovo ThinkSystem SR655 server has set a new 1-node 1-socket performance world record with the SPECompG_base2012 metric 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 SR655 that was published on August 7, 2019. 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 SR655 server has set a new 1-node 1-socket performance world record with the SPECompG_base2012 metric of the SPEC OMP2012 Benchmark.
This new benchmark result, published in a new SPEC report on August 7, 2019, demonstrate that the ThinkSystem SR655 continues Lenovo’s leadership with outstanding performance for the server industry.
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 SR655 has achieved the following score (1):
- SPECompG_base2012 = 21.6
This result is the best one-node 1-socket performance in the industry, 71% faster than Huawei’s 2288H V5 result (2).
|Lenovo (1)||ThinkSystem SR655 (AMD EPYC 7742, DDR4, 3200 MHz)||21.6||64||1||256 GB|
|Huawei (2)||Huawei 2288H V5 (Intel Xeon Platinum 8280, DDR4, 2933 MHz)||12.6||28||1||192 GB|
The SR655 was configured as follows for the benchmark audit:
- Lenovo ThinkSystem SR655
- 1x AMD EPYC 7742 Processor (64 cores, 2.25 GHz)
- 256 GB memory (8 x 32GB RDIMMs at 3200 MHz)
- 1x 1TB SATA HDD
- Red Hat Enterprise Linux Server release 7.6, Kernel 3.10.0-957.el7.x86_64
Results referenced are current as of August 7, 2019.

About the ThinkSystem SR655
The Lenovo ThinkSystem SR655 with the next generation AMD EPYC architecture delivers outstanding TCO for virtualization, big data, analytics, and scale up software defined deployments. It offers two-socket performance in a 2U, single-socket design, featuring higher core, and storage density; increased I/O throughput with less latency; along with built-in system security.
With the enterprise class AMD EPYC 7002 Generation processor, the world’s first 7nm data center CPU, the SR655 features up to an unprecedented 64 cores with 128 PCIe Gen4 lanes in a single socket to reduce bottlenecks and increase server utilization.
Compared to the previous processor generations, ThinkSystem servers with AMD architecture deliver 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.
Key features of the SR655 include:
- Multi-GPU optimized rack server, providing support for up to 6 single-wide GPUs that offer more workload acceleration in AI Inference and virtualized desktop infrastructure (VDI).
- 64 cores to handle heavy-lift virtualization workloads; provides cutting edge application efficiency in health care applications such as EMR, PACS, and medical imaging or electronic trading platforms for financial services applications.
- 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
- Parallel support libraries
