What a difference a year can make! Last year Fujitsu was focused on its K-Computer. With 88,128 traditional Sparc CPUs–each with eight cores for 705,028 total, K-Computer was declared the world’s fastest supercomputer in the 2011 Top500 Supercomputer list. In 2012, however, the K-Computer lost out to IBM’s Sequoia, which boasted more than twice as many PowerPC cores –1.5 million. Despite its high speed, the K-Computer consumed almost twice as much power per floating-point operation (825 GFlop/kWatt) compared to supercomputers based on the Xeon Phi, which are rated almost three times higher (2499 GFlop/kWatt) by the Green500 List. In addition, the ability to add 60-cores at a time with a single PCIe card drastically cuts the cost of HPCs.
