Summary

As power and cooling costs continue to occupy a substantial portion of IT budgets, IT departments are placing a strong emphasis on power efficiency to minimize the Total Cost of Ownership (TCO) when selecting server hardware. This paper assesses the power efficiency of the new Dell PowerEdge C6615 server, a model designed in the multi-node, 2U form factor. Due to its adept balance between density and expandability, this form factor is widely used across various edge and telecom use cases.

Test configuration

AMD STREAM

STREAM benchmark is used to calculate the memory bandwidth of a system. The Dell PowerEdge C6615, featuring the AMD EPYC 8534P 64-Core processor, shows a remarkable up to 142% enhancement in performance per watt per dollar. It also boasts an impressive up to 73% increase in performance per CPU dollar when compared to the Dell PowerEdge 1S server equipped with the AMD EPYC 9534P 64-Core processor[1] (Figure 1).

High-Performance Linpack (HPL)

High-Performance Linpack (HPL) is a benchmark used to measure the floating-point computing performance of a computer system. It is specifically designed to assess a system’s ability to solve a dense system of linear equations. HPL is widely used in the high-performance computing (HPC) industry and is considered a standard benchmark for evaluating supercomputers and clusters.

The results have shown outstanding cost-efficiency, revealing a remarkable up to 335% enhancement in performance per watt per dollar, and a substantial 210% increase in performance per CPU dollar when compared to PowerEdge 1S server equipped with the AMD EPYC 9534P 64-Core processor[3] (Figure 3).

When compared to a PowerEdge 1S server equipped with the AMD EPYC 9334 32-Core processor, the results highlight exceptional cost-efficiency. It also features an impressive up to 209% improvement in performance per watt per dollar and a substantial 132% increase in performance per CPU dollar[4] (Figure 4).

SPEC CPU 2017

The SPEC CPU® 2017 benchmark from the Standard Performance Evaluation Corporation (SPEC®) provides a comparative measure of compute-intensive performance using workloads developed from real user applications. SPEC CPU 2017 is the industry-standardized CPU intensive suite of benchmarks for measuring and comparing compute intensive performance, stressing a system's processor, memory subsystem and compiler. This benchmark is used by hardware vendors, IT industry, computer manufacturers, and government.

The results demonstrate remarkable cost-efficiency, with an impressive up to 281% improvement in performance per watt per dollar, and a substantial 172% increase in performance per CPU dollar when compared to a PowerEdge 1S server equipped with the AMD EPYC 9534P 64-Core processor[5] (Figure 5).
