I saw this on another board. The chart on the right shows per generation and cumulative IPC improvements from Dothan to Broadwell:
Note that IPC improvements have been fairly linear, contradicting the claims that Intel is artificially holding back performance on new uarchs. I do agree that Intel could be cranking the clock speeds up a bit if it chose to target that in design, but that's a different issue.
