That makes sense. I had the same doubt as Marcan.
I don't get Intel Turbo Boost. If my laptop's CPU operates at a sustained 3.3GHz with all threads pegged, why didn't they just rate it that?

So do that then? Or just offer multiple ratings (at this power you can achieve this clock). Knowing the real peak TDP is useful.

The real TDP makes the chips much less efficient

That's the real answer: marketing wank which makes no technical sense.

Scalar loads use much less power than vector loads. You're not measuring a sustained full workload if you're just doing compiles, etc.
-
Try mprime's stress test, etc. although Intel CPUs generally have a hard-wired AVX offset so it won't even try to reach the peak frequency.

I think you and I are abby-normal end users. Most people are after single thread peak performance 95% of the time.

... which is even higher since it won't bump up against TDP or power limits. Yet they artificially rate the CPU lower.

it's all marketing.

As long as the processor have some slack to the max TDP there is no limit to the amount of oc that Turbo Boost can apply.
