X-Bit Labs pits Intel’s two superstars against each other, the mighty but slightly elderly i7-990X Extreme Edition  and the brand new i7-2600K.  They both have roughly the same 3.4GHz speed but achieve it in different ways, with the 990X running 133MHz with a 26x multiplier and the 2600K adds a 34x multiplier to the 100MHz base and both vary their speed depending on tasks.  Turbo mode is also mostly the same, with the 2600K reaching a slight higher speed with it’s 4/8 cores.  Can the extra cores and enthusiast level motherboard on the 990X push the performance past the new technology in SandyBridge?  Find out here.
