You are correct chew* .Don't forget that IPC(or CPC) is only one part of performance equation.There is working frequencies too . BD is supposed to be able to clock very high,so 2module/4 core Zambezi should not only be faster than Deneb QC at the same clock ,but should be able to work at much higher clocks from the start(think 4Ghz stock with Turbo on top of that). There are rumors of 3.5-3.8Ghz range for 95W 8 core parts .
