Power 7 vs. SoC
With the plug pulled on the 10 petaflop Power7-based Blue Waters for NCSA, IBM is working with two Department of Energy labs for a 10 petaflop ‘Mira’ system at Argonne National Lab and a 20 petaflop “Sequoia” at Lawrence Livermore. The current top supercomputer in the world, the Japanese K, can sustain 8.162 petaflops.
The Power-7 chip was set to perform at 256 gigaflops per 8 cores and consume 200 watts, where the Blue Gene/Q SoC will pull 204 gigaflops per processor, with an 18 core count, and consumes 55 watts at peak. With a significant increase in performance the Blue Gene/Q chip delivers 15 times as many peak FLOPS its Blue Gene/P counterpart and 36 times as many as the original Blue Gene/L SoC....
