quote: The 12-core, 4Ghz Power8 chip can execute 96 threads simultaneously, and is expected to be 2x to 3x more powerful than IBM's Power7 chip, which was used in the Watson supercomputer that competed on the game show. The Power8's capability to move data has been dramatically improved over previous designs, including the interim Power7+ chip that IBM shipped in 2012. According to the Hot Chips presentation on Monday by Jeff Stuecheli, the chief nest architect for Power8, the new processor features 230 GB per second of sustained memory bandwidth between the L4 caches and the processors, and total peak I/O of 48 GB per second along the new on-die integrated PCI-Express 3.0 controllers, making it a very speedy chip. One of the cool things IBM has done with those integrated PCI-Express 3.0 controllers is to design a new transport layer called the Coherence Attach Processor Interface (CAPI) that will enable co-processors, including GPUs or field programmable gate arrays (FPGAs) to be connected directly to the Power8 chip and to share data stored in its memory.
