writes "So what's the world's fastest microprocessor? Intel's latest X86? No, maybe later. AMD? No. Itanium? Heck no, never. SPARC? Goodness no, are they still around? IBM's POWER7? Closest... but not at the moment. Today it's IBM's zEnterprise 196, i.e. the newest mainframe model. A mainframe holding the honor of world's fastest microprocessor? Yes, and it's time to get used to it. IBM's engineers have just rocked the server world by taking the world's fastest microprocessor, clocked at a constant and unsurpassed 5.2 GHz (!) with new out-of-order instruction execution (while keeping mainframe instruction result verification and on-the-fly fault recovery and core fail-over), putting 96 cores of them into a single machine, surrounding them with 4 (!) levels of cache memory (each far larger than anything else), providing 3 TB (usable) of the world's first and only RAIM-protected fast memory (that's RAID for RAM), giving them scores of dedicated assist processors, accelerating the already famous mainframe I/O... and, to top it all off, adding in mainframe-managed closely attached blade servers to mop up the data center floor. IBM says more than 100,000 virtual servers can run on a single zEnterprise System with zEnterprise BladeCenter Expansion feature. And of course it's built to keep your important applications running continuously, no excuses, with no interruptions for either hardware or software changes.
