AMD uploaded a YouTube clip in which it publicly slaps SYSmark, claiming the benchmark is not objective and biased towards Intel. The firm points out that the U.S. Federal Trade Commission (FTC) has required Intel to post a disclaimer when using data from SYSmark, stating the benchmark may only be optimized for Intel platforms, and illustrates that there's a much bigger performance discrepancy between Intel and AMD CPUs in SYSmark than in other benchmarks like PCMark:
In AMD's testing SYSmark AMD has found that SYSmark provides data that is not comparable to the difference in real world performance when it compared AMD and Intel CPUs, giving a performance delta of 50% for a comparable system when other benchmarks like PCMARK only give a delta of 7%.
SYSmark is often used in advertising material and this isn't the first time AMD has slammed the benchmark. In 2011, AMD left the BAPCo consortium and issued a press release warning consumers not to trust SYSmark 2012. Similarly, NVIDIA and VIA also left the consortium in 2011 because they felt that SYSmark did not accurately represent real-world PC usage scenarios and workloads.
