Tianhe-2 supercomputer claims the lead in Top 500 list, thanks its 3.1 million processor cores

As predicted, Chinese supercomputer Tianhe-2 has now been crowned the most powerful supercomputer in the world. Arriving years ahead of schedule, and packing 32,000 Xeon processors alongside 48,000 Xeon Phi accelerator processors, the supercomputer can manage a quadrillion mathematical calculations per second (33.85 petaflops), double that of last year's king (and closest rival), the Titan. In this year's results, 80 percent of the Top 500 used Intel processors, while 67 percent had processors with eight or more cores -- as clock speeds stall, supercomputer development has now focused on processors running in parallel. Top 500 editor Jack Dongarra adds that "most of the features of the [Tianhe-2] system were developed in China, and they are only using Intel for the main compute part," meaning that you can expect to see more Chinese entrants (and possibly champions) over the next few years. For now, however, the US still claims the majority of the Top 500, with 253 top-ranking supercomputers.

After giving very deeep discounts on the Phis. So deep Nvidia would not touch it with a ten feet pole. So deep Intel could not make a peeenyyy out of that deal. Google it - comments about that when they first announced the win - way before the computer was completed.
Intel has lost some credibility after the episode of cheaping on Antutu benchmarks. I did some checking and found that the steady decline of INTC (despite repeated announcements of Baytrail's arrival and performance superiority), seems to coincide with the expose event. The world doesn't need another company like slimy Sammy.
The news you are missing is that the son of Larrabee, Xeon Phi aka 22nm Knights Corner, is the accelerator card for parallel workloads. It's also going to get worse for competitors when the 14nm Knights Landing successor tips up, it can be used as a standalone chip too as well as a PCI-E accelerator giving HPC users more Intel options e.g, Xeons, Xeons and Xeon Phi or just Xeon Phi.
