Nvidia calls out Intel for cheating in Xeon Phi vs. GPU benchmarks. Nvidia claims Intel used four-year-old data to make its new chips sound better.

That old chestnut again? Intel compares their current gen hardware against older NVIDIA kit.

In this case, it looks like Intel opted for the classic using-an-old-version-of-some-benchmarking-software manoeuvre. Intel claimed that a Xeon Phi system is 2.3 times faster at training a neural network than a comparable Maxwell GPU system; Nvidia says that if Intel used an up-to-date version of the benchmark (Caffe AlexNet), the Maxwell system is actually 30 percent faster. And of course, Maxwell is Nvidia's last-gen part; the company says a comparable Pascal-based system would be 90 percent faster.

On the 38-percent-better-scaling point, Nvidia says 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. Nvidia states that modern GPUs, paired with a newer interconnect, scale "almost linearly up to 128 GPUs."


Intel has always been a proud and honorable corporation with uplifting leadership. I don't think the word cheat is in their vocabulary. :hurting:
 
What else can they do? They can't really win on price/perf since AFAIK that sector isn't burdened as much by budget, but more power efficiency and absolute performance.

If you can't win, cheat. If you get caught, pull a PR stunt. That usually works.
 
People buying these HPC processors know exactly how it performs. So this is nothing but PR for the uninformed.

However GPUs got a huge issue in terms of memory limits. With Xeon Phi for example, besides omnipath, you got 6 channel DDR4 you can fill up. And we all know what happens when a GPU runs out of memory.

There is a reason why Xeon Phi shipments have exploded with 8x growth.
 
Nvidia has been cheating for years they really have no right to call anyone a cheater. They have modified 3D mark scores since the GeForce 4
