On to more pertinent details, and the leaked slides say that top-end CPU will have a TDP of 77W, down from the 95W of the current Sandy Bridge range. We were told that the 22nm, 3D transistor technology being deployed for Ivy Bridge would produce either a 50 per cent power saving for the same frequency, or 37 more frequency for the same power draw.Intel's Ivy Bridge lineup is expected around March/April 2012.
A bit of rough maths shows the drop from 95W to 77W to be 19 per cent, meaning that we expect frequency to increase by roughly 23 per cent. That could mean that the Core i7-3600K could have a nominal frequency of around 4.2GHz and the Core i5-3500K to be clocked at around 4GHz.
