Nvidia calls out Intel for cheating in Xeon Phi benchmarks

 

Nvidia has called out Intel for cheating in their recently released Xeon Phi benchmarks stating that Intel was using old benchmarks and using last generation Nvidia hardware for their comparisons. 

Intel's Xeon Phi is a PCI mounted CPU that can have up to 72 Atom CPU cores on a single chip, making this CPU well suited to parallel computing tasks. 

Where Intel have claimed a 2.3x advantage over Nvidia they used a benchmark called Cafe AlexNet to measure relative performance. Nvidia states that had Intel used the most up-to-date version of the benchmark Nvidia would have had a 30% advantage, saying that this would increase to a 90% advantage had Intel used a new Pascal-based system rather than an older Maxwell based GPU.

In Intel;s scaling testing Intel claims that their Xeon Phi processors have 38% better scalability, though again this is using old data that was taken from a 4-year-old Kepler K20 based servers. Nvidia states that with their new interconnect, likely NVlink, that their modern GPUs can scale "almost linearly up to 128 GPUs", giving Nvidia superior scalability. 

As always, benchmarks that come from manufacturers should always be taken with a grain of salt, as these benchmarks have been carefully selected to showcase their products in the best light. Intel has since released the following statement regarding Nvidia's cheating claims. 

 

It is completely understandable that Nvidia is concerned about Intel in this space.

Intel routinely publishes performance claims based on publicly available solutions at the time, and we stand by our data.
