Nvidia calls out Intel for cheating in Xeon Phi vs. GPU benchmarks

reader comments 3 Share this story Nvidia has called out Intel for juicing its chip performance in specific benchmarks—specifically, that Intel published some incorrect “facts” about the performance of its long-overdue Knights Landing Xeon Phi cards.Nvidia’s primary beef is with the following Intel slide, which was presented at a high performance computing conference (ISC 2016). Nvidia disputes Intel’s claims that Xeon Phi provides “2.3x faster training” for neural networks, and that it has “38 percent better scaling” across nodes. At this juncture I should point out that juicing benchmarks is, rather sadly, par for the course. Whenever a chip maker provides its own performance figures, they are almost always tailored to the strength of a specific chip—or alternatively, structured in such a way as to exacerbate the weakness of a competitor’s…
