NVIDIA Calls Intel's Bluff on Xeon Phi vs. GPU Benchmarks

NVIDIA accused Intel of cheating in its ISC 2016 presentation, particularly in a performance-related slide, in which it claimed that its "Knights Landing" Xeon Phi HPC processor provides faster training of neural nets than NVIDIA "Maxwell" GPUs. In a slide, Intel claimed that a Xeon Phi HPC processor card is 2.3 times faster at training deep-learning neural nets, and 38 percent better scaling across nodes, than NVIDIA "Maxwell" GPUs, which triggered a swift response from the GPU maker, which made significant investments in deep-learning technologies over the past three years.

NVIDIA argued that Intel is using the classic technique of running outdated benchmarks to test its neural net training speeds. The company says that if Intel used the latest version of the same benchmark (Caffe AlexNet), the "Maxwell" GPU will be found to be 30 percent faster than the Xeon Phi at training neural nets. NVIDIA also notes that "Maxwell" is only its previous-generation part, and a "Pascal" based HPC processor would easily be 90 percent faster than the Xeon Phi. More importantly, NVIDIA notes that Intel compared 32 of its new Xeon Phi servers against four-year-old Nvidia Kepler K20 servers being used in ORNL's Titan supercomputer. The latest "Pascal" GPUs leverate NVLink to scale up to 128 GPUs, providing the fastest deep-learning solutions money can buy.

"Leverate"?
Is that meant to be leverage?

It can't be even considered a lie - nV is whining about Intel using an older version of some benchmark and comparing it's products to a previous generetion of GPUs... What a shame...

Nvidia is marketing their solutions and that is all. 'Look, we have the longest/biggest/saddest PR'

As always, we'll see the real benches later.

pffft.....Nvidia doesn't lie. They just have a breakdown in communication between their Engineering Dept and their Marketing Dept. ;)

Intel has always been full of shit. They're criminals and pathological liars.

I bet they fund Hillary handsomely lulz

Stop being a bitch nVidia and put out some of your own. If I was upgrading my datacenter I'd be looking for information, not your shade.

Correct still a good benchmark on the performance of them however.

Not really. They tend to favor certain APIs due to how the kernels are written. If you believed bitcoin you'd think NVIDIA was losing the performance battle, for example.

In pure floating point the fury x can deliver 8.6tflops and the 980ti can only deliver 5.6tflops. There is a reason why amd cards are better at specific things.
