What DirectX is, and why you will not see it in a non-Microsoft machine.

No, they simply stopped scaling through Clock speeds is simply because it provides no added benefits. In order to make use of a 4+ghz clock, you need a larger pipeline otherwise many of the cycles are just sitting there doing nothing and creating more pipeline stages are pretty capped out because you will eventually get stalled anyways while waiting for things like memory write to complete.

Heat and Power consumption create different issues where the clock timming gets messed up and create errors but it can be remedied to with additional cooling which again adds to the increased power consumption (Yeah, you need to use energy to remove energy).

SImply, they stopped creating high clock speed is due to poor efficiency, not technical debt.

That's an Architectural limitation that you're describing, not a technical one, when a Pipeline stalls it has to start from scratch, the longer the pipeline the more clock cycles that are wasted.
Intel and AMD have "ways" of getting around pipeline stalls.
Hyper threading is one such way, just schedule another thread.
The other is through a more advanced branch tree predictor, scheduler and pre-fetch unit; this is something Intel has been very Aggressive with since the Core 2 Duo with great effect.
With fast low-latency caches and lots of bandwidth, you can hide the hit from a pipeline stall as restarting from scratch isn't nearly as punishing, but it's best to avoid such a circumstance in the first place.

Also, there is benefit to exceeding 4ghz. Otherwise overclockers (Such as myself) would see zero performance increases.
Just right now the TDP has been a limiting factor, especially with AMD chips.
My processor at 4.8ghz consumes almost 220w of power. (I've added more voltages of course.) But the performance improvement has been in the realm of 25% in some games even with the Hyper Transport and the NB clock at stock speeds.

You can also see improvements in speed with Turbo Core from both AMD and Intel even if the Turbo clocks exceed 4ghz.

But to say there is no benefit after 4ghz is simply false.
