ThinkSystem SR645 Sets 9 World Records with New SPECcpu Benchmark Results

The Lenovo ThinkSystem SR645 server delivers world-record two-socket performance for compute-intensive applications with new results of the SPEC CPU2017 benchmark.

These new benchmark results, published in new SPEC reports on March 16, 2021, demonstrate that the ThinkSystem SR645 continues Lenovo’s leadership with outstanding performance for the server industry.

The ThinkSystem SR645 has achieved the following scores:

• SPECspeed2017_int_energy_base: 78.5
• SPECspeed2017_int_energy_peak: 78.6
• SPECspeed2017_fp_base: 255
• SPECspeed2017_fp_energy_base: 593
• SPECspeed2017_fp_energy_base: 601
• SPECrate2017_int_energy_base: 1610
• SPECrate2017_int_energy_peak: 1700
• SPECrate2017_fp_energy_base: 1320
• SPECrate2017_fp_energy_peak: 1400

SPECspeed2017 scores are ideal for measuring single-threaded compute-intensive applications, such as High Frequency Trading (HFT) and other financial industry workloads.

SPECrate2017 scores are ideal for measuring multi-threaded compute-intensive applications, such as High Performance Computing (HPC) workloads.

The Lenovo ThinkSystem SR645 server was configured as follows:

• Processors
  • 2 x AMD EPYC 7763 processor - 64 cores, 2.45 GHz, 256 MB L3 cache per processor
  • 2 x AMD EPYC 7713 processor - 64 cores, 2.00 GHz, 256 MB L3 cache per processor
  • 2 x AMD EPYC 72F3 processor - 8 cores, 3.70 GHz, 256 MB L3 cache per processor
• Memory
  • 512 GB system memory
  • 2 TB system memory
• SUSE Linux Enterprise Server 15 SP2

The results are current as of March 16, 2021.

The Lenovo ThinkSystem SR645 server, now with AMD EPYC 7003 Series processors, delivers outstanding TCO for transactional database, ERP, virtualization and software-defined deployments. The combination of two AMD EPYC 7003 CPUs with class-leading memory speed and core density in a 1U chassis is a step forward compared to prior generation two-socket servers. Lenovo’s lauded system reliability, management capabilities, and security infrastructure layer on to the exceptional value that the ThinkSystem SR645 brings to the data center. The ThinkSystem SR645 features two processors with up to an unprecedented 128 total cores with 128 PCIe Gen4 lanes to bring better efficiency to customers looking for the ultimate in core density and high speed direct attached storage in their data centers.

Compared to previous processor generations, the ThinkSystem SR645 delivers up to 2X performance and 4X floating point capability, providing faster data transfer and transaction capabilities without sacrificing memory capacity or I/O with PCIe Gen4 support and faster memory speeds up to 3200 MHz.

Key features:

• 128 cores across two processors to handle heavy-lift ERP, CRM, and virtualization workloads; provides cutting edge application efficiency in database applications, or electronic trading platforms for financial services applications.
• Compact 1U server with dense NVMe storage is an ideal platform for software defined storage or a hyperconverged solution
• Class-leading core density in the 1U form factor coupled with high speed 3200 MHz memory and PCIe Gen4 IO makes an ideal platform for advanced analytics

SPEC CPU 2017 is SPEC's next-generation, industry-standardized, CPU intensive suite of benchmarks for measuring and comparing compute intensive performance, stressing a system's processor, memory subsystem and compiler. This benchmarks provides a comparative measure of compute-intensive performance using workloads developed from real user applications.

The SPEC CPU 2017 benchmark suite measures server performance in the following ways:

• SPECspeed 2017 is to compare time for a computer to complete single tasks
• SPECrate 2017 is to measure the throughput or work per unit of time.

This benchmark is targeted for use by hardware vendors, IT industry, computer manufacturers, and government.
