Intel's Knights-branded Xeon Phi chips remain the most familiar "many-core" accelerators or coprocessors. However, another name has emerged recently: PEZY, whose 1,024-core chips were used in the top 3 most efficient supercomputers. Tom's Hardware reports that PEZY's next generation of chips will boost the core count to 4,096 and integrate Imagination's 64-bit MIPS Warrior CPU onto a system-on-a-chip:

PEZY Computing, a Japanese firm that makes the top three most efficient supercomputers in the world, according to the Green500 list, announced that it will integrate Imagination's highly efficient 64-bit I6400 CPUs into its many-core architecture.

The PEZY SC-2 will be PEZY's next-generation system, which will increase the 1024 core count of the first generation PEZY SC to 4096 cores, or four times more. PEZY's many-core accelerator has been combined with Intel CPUs from top supercomputers to significantly increase their efficiency for computing tasks. For instance, the Shoubo supercomputer, which uses Haswell XEON CPUs and PEZY SC many-core accelerators, was able to break the world record with 7 GFLOPS/W performance.

In the November edition of Green500, the top 23 supercomputers used a heterogeneous architecture with many-core accelerators. In the updated June edition of this year, that number increased by 40 percent, and now the top 32 supercomputers are using many-core accelerators. These supercomputers all use accelerators from AMD, Intel, Nvidia and PEZY. The current top 3 supercomputers are manufactured by PEZY Computing and Exascaler Inc, and include Haswell or Ivy Bridge Xeons as well as PEZY many-core accelerators.

Presumably the integration of the MIPS CPU could allow relatively power-hungry Intel Xeons to be ditched entirely.
