IBM announced information about its 5.2GHz processor at the Hot Chips conference, its a new CISC chip designed for mainframes that run bulky, large programs that require lots of memory.
At the Hot Chips 2010 conference in Palo Alto, IBM executives described the z196, which will power its Z-series of mainframes, which can cost hundreds of thousands of dollars, if not over a million. IBM will ship the chip in September, said Brian Curran, an IBM distinguished engineer. The mainframe itself was announced in July.
IBM also previously claimed the title of fastest microprocessor with the POWER6 chip, which ran at speeds of up to 4.6 to 4.7 GHz, and its own z10, a 2008 chip which ran at speeds of up to 4.4 GHz.
