One of Intel's key developments is its 72-core Knights Landing (KNL) platform, which it claims offers 5x the performance and 8x the power efficiency of the competing GPU solutions.
You shouldn't just repeat these specious claims without qualification. As these measurements were against Kepler-generation GPUs, they weren't really "competing GPU solutions".
KNL is also bootable, which is a key value proposition.
I think the bigger value proposition is that they can integrate with legacy codebases, without the sort of rewrite necessary to exploit CUDA. You can program them in any language, and run basically any existing software on them.
But for people who prize FLOPS/$ or FLOPS/W above all else, GPUs (and FPGAs) are still where it's at. ...unless you can afford to make your own ASIC, like Google.
