I'm not sure what you mean. Why would ideas that increase single thread performance "perish"? Let's say hypothetically Intel does some analysis and determines that if they make certain changes to the branch predictor they can get an extra 4% single thread performance.

If AMD was on their throat like back in the Opteron days they make those changes immediately because every little bit they can gain is important. But since AMD is not only not on Intel's throat, but are tripping over their own feet, maybe Intel leaves that idea on the shelf, because they don't really benefit from an extra 4% gain today.

Having a couple gains available on the shelf with little effort required would come in handy if AMD pulled a rabbit out of their hat, or Intel found itself in a situation where all their investigations into further performance increases ended up failures, so rather than roll a new architecture that has no performance increase (and listen to the pundits say Intel is done) they pull a few things off the shelf they'd been saving and continue to report the ~5-10% gains they have been.

The net effect would be like the earnings smoothing that some companies do, playing accounting games that reduce their earnings in quarters where they exceed expectations, so that they can report those earnings in quarters where they otherwise would have fallen short.
