Intel, a renowned technology company, has once again found itself in the midst of controversy as accusations regarding benchmark optimizations come to light. The company has been accused of inflating benchmark scores by the Standard Performance Evaluation Corporation (SPEC), a prominent benchmarking organization.
SPEC recently discovered that Intel had integrated specific optimizations into its oneAPI DPC++ compiler, which impacted the benchmarks “523.xalancbmk_r” and “623.xalancbmk_s.” These benchmarks evaluate the performance of Xalan and the XSLT (eXtensible Stylesheet Language Transformations) output. Upon investigation, SPEC determined that the compiler utilized prior knowledge of the SPEC code and dataset, narrowly improving the performance of these specific benchmarks.
Consequently, in accordance with rule number 14 of the SPEC 2017 Run and Reporting Rules, SPEC decided to cancel this optimization, resulting in the removal of over 2600+ benchmark results. The organization aims to prioritize optimizations that have wider applicability rather than targeting specific benchmarks.
Benchmark results play a crucial role in the competition between technology companies like Intel and AMD. These results, often cited to highlight the instructions per clock cycle (IPC) of processors, influence customers’ decisions. Intel’s alleged benchmark optimizations may have been an attempt to demonstrate the superiority of its Xeon CPUs over AMD’s EPYC counterparts. However, with AMD’s increasing presence in data centers, it appears that Intel’s previous attempts to discredit AMD through derogatory remarks and benchmark manipulations have fallen short.
This is not the first time Intel has faced allegations of questionable practices in benchmarking. In previous instances, benchmarking software like Cinebench version 11.5 and PCMark 2005 were found to contain code that favored Intel processors and deliberately hindered performance on AMD CPUs. Additionally, an issue arose with BAPCo’s SYSMark benchmark, where AMD and Nvidia accused the organization of showing bias towards Intel. These incidents have raised concerns regarding the fairness and reliability of benchmarking within the industry.
As the technology landscape continues to evolve, it is crucial for companies to prioritize transparency and ethical practices. Such controversies underscore the significance of independent and unbiased benchmarking processes to ensure fair competition and informed consumer choices.
