What I'm trying to say is that the algorithms it uses to do its calculations in the most efficient manner possible have been tweaked slightly.
Algorithms are on the coding side. The CPU can only run whatever instruction it is fed. Namely... addition, subtraction, multiplication, division, read things here, write things there, move things from this to that... CPUs don't have "algorithms" built-in unless you consider basic mathematical operations "algorithms".
Haswell is just faster at doing those basic operations than Ivy Bridge.
I'm not really sure how Intel calculate their TDP values any more. My quad 2.2GHz i7 is at this very moment using 43.5 W, (less than its TDP of 45W) yet has all 8 virtual cores (loaded with 8x yes>/dev/null) running at 2.5 GHz, far above its default clock.
TDP is Thermal Design Power. On one hand, it's just how much thermal the CPU is expected to push out, so power consumption is actually higher than that, still. You're looking at roughly 50W. It's the absolute worst case scenario with the processor completely bogged down.
I'd guess your Core i7 quad at 2.2GHz is a 2720QM (2011 MBP model). That one can actually Turbo Boost to 3.0GHz, so you're just a bit shy of maximum load.
In any case, the story is that Haswell doesn't improve on power consumption.w
Do you have that sentence above backwards? I believe revolutions are considered dramatic and evolutions are considered gradual. Are you saying that Haswell is not a big change for Laptops? But that Broadwell is going to be where things really change?
Unless you're saying human evolution (from "monkeys", according to popular theories), doesn't mean as much as human revolution (winning a conflict of political interests), I think it's fair to say "evolution" is the dramatic change.
And yeah, I am saying that Haswell isn't a big change for laptops. It's a big change for those who are reliant on the integrated graphics solution that are looking for more performance in that area, but it's not a huge change anywhere else.
The manufacturing process is still the same 22nm that's used with Ivy Bridge, for one thing.
Broadwell moves to a new manufacturing process (14nm). Typically, when that happens, things improve dramatically. That's why Ivy Bridge (22nm) is dramatically faster and more efficient than Sandy Bridge (32nm).
