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.

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).

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).
