The L3 cache is shared and has a mindblowing size, let's not forget that.
Plus you get way more thermal room.
Plus you can disable SMT.
And there is always more than 1 process running if you take into account kernel threads.
So I would say way quite a lot more than 2%. More like 10%.

And if is really in the low double digits, you're back to single digits when you go to 80 cores. On the positive side, I don't think multi-user systems would be where they are today if we hadn't been staring at a future full of hardware that can only be fully utilized by embarrassingly parallel tasks.
