Intel Ivy Bridge to have 77W TDP?

Posted on Tuesday, October 18 2011 @ 21:48:13 CEST by

Newly leaked details about Intel's Ivy Bridge confirm the company will continue to use its Core i3, i5 and i7 branding with a 3 prefix rather than the 2 of the current Sandy Bridge lineup. Interestingly, the information also indicates the high-end chips may have a TDP of 77W, compared to 95W of the current high-end Sandy Bridge chips. Another rumor is that Intel's Q67, Q65 and B65 chipsets will not support Ivy Bridge due to a lack of firmware space, while Z68, P67, H67 and H61 chipsets are all compatible, in theory.
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.

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.
Intel's Ivy Bridge lineup is expected around March/April 2012.
