ThinkSystem SR635 Sets World Record with New 1U 1-Socket SPECpower Result

The Lenovo ThinkSystem SR635 has set a new one-processor performance world record with a 1U rack server for the SPECpower_ssj 2008 benchmark.

The SPECpower_ssj 2008 benchmark is the first industry-standard benchmark that evaluates the power and performance characteristics of single server and multi-node servers.

The ThinkSystem SR635 server delivered the following SPECpower_ssj 2008 1-socket world record performance result for a 1U rack server:

• SPECpower_ssj2008 = 18,555 overall ssj_ops/watt

The SR635 was configured as follows:

• 1x AMD EPYC 7742 processor (64 cores, 2.25 GHz core frequency, 256 MB L3 cache)
• 128 GB of Lenovo TruDDR4 memory
• 1x 128GB M.2 SSD
• SUSE Linux Enterprise Server 12 SP4
• Oracle Java HotSpot 64-bit Server VM, version 11.0.3 (JVM)

Results referenced are current as of August 7, 2019.

The Lenovo ThinkSystem SR635 with the next generation AMD EPYC architecture is ideal for I/O intensive workloads, from databases and analytics, to virtualized environments (VDI) and hybrid cloud solutions. This 1U, single socket rack server is right-sized to offer the balanced processor power, performance, memory and I/O of a 2-socket server at the value and total cost of ownership of a 1-socket server.

With the enterprise class AMD EPYC 7002 Generation processor, the world’s first 7nm data center CPU, the SR635 features up to an unprecedented 64 cores with 128 PCIe 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 with PCIe Gen4 support and faster memory speeds up to 3200 MHz, providing faster data transfer and analytics without sacrificing memory capacity or I/O.

Key features of the SR635 include:

• High capacity storage, with support for up to 16x2.5” drives. When the server is outfitted with 16 low-latency NVMe drives, the server is an ideal platform for OLTP, Analytics, software-defined and HPC storage.
• Up to three single-wide GPUs to provide workload acceleration for AI inference and VDI applications.
• Full support PCIe Gen4 to achieve up to 16 GT/s for accelerated data transfer speeds. This new technology enables the next-generation of technology for grid-computing and high-frequency trading analytics in the financial services sector, and capacity planning and supply chain optimization in both the telco and manufacturing industries.

The SPEC Power benchmark suite measures the power and performance characteristics of server-class computer equipment. It is used to compare power and performance among different servers and serves as a toolset for use in improving server efficiency. This benchmark is targeted for use by hardware vendors, IT industry, computer manufacturers, and governments.
