Measuring IPC / Performance Generation over Generation

So a question that I had earlier today.

With all of the sidechannel flaws that intel has in its processors. The fixes for which are being mitigated via microcode / bios / software.

When Intel eventually releases its next generation chips that do not have these flaws (or less of them); Are they going to compare the percentage improvement in IPC or overall performance to pre sidechannel fixes earlier generations, or post sidechannel fixes variants of earlier generations?


I smell some marketing BS coming.....

Almost certainly post-fix. It will put the newer parts in a more positive light performance wise (good for marketing), and generally be more representative of most relevant real-world scenarios as well. Most OSes are integrating microcode updates and major OEMs have been pushing out updated firmware.
