Intel chips are now used in almost 80 percent of world's fastest supercomputers, while HP and IBM are used in 60 percent according to the 33rd Edition of TOP500 Supercomputer released on Tuesday.

The new Intel Xeon Processor 5500 series extends the world-record performance and energy efficiency of the TOP500 supercomputers demand, and we are delighted to see once again that more supercomputers than ever before are embracing the Intel Xeon processor,” the company said.

It has a total of 399 systems running on Intel processors, up from 75.8 percent or 379 systems in a year earlier, according to the TOP500 list.

“As a result, we will continue to push the boundaries of the world's highest end supercomputers ever than before, as we emerges as one of the fastest growing segments of Intel's server business, said Kirk Skaugen, VP and general manager of Intel's Server Platforms Group.

Holding onto the No. 1 spot with 1.105 petaflop/s (quadrillions of floating point operations per second) is the Roadrunner system at DOE’s Los Alamos National Laboratory (LANL) which was built by IBM and in June 2008 became the first system ever to break the petaflop/s Linpack barrier.
