The top turbo bin is 4.4Ghz. It's likely that they sell faster parts off roadmap.

Thanks for the nice data. AFAIK Intel uses a GeoMean for their IPC summaries. GeoMean is commonly used for growth rates. Might be more comparable if you would too.
I believe the Intel numbers are based on a large number of workloads which are together supposed to be representative of overall workloads. So even though the workload mix is likely not identical and changes over time we assume that if there are enough samples there is a reversal to the mean and...
I used the numbers published by Intel (but as SAAA pointed out I got the Merom number wrong)
It's in many places, but here is one upto Skylake.

Yes it was relative to Sunny Cove...
Not saying anything about low hanging fruit . Point was it's pointless to use incremental percentages relative to the previous part to compare something as far apart as Merom and Golden Cove which have completely different baselines. It's not just pointless, it's actively misleading.
There's...
Good point. So Merom is still better than Golden Cove.
That's only true for Apple, the other ARMs are still behind the big cores. The highend ones are comparable to Atom.
The arguing about percentages is always interesting.
Let's say we start with Prescott=1 .00+40% Merom 1.4 + 12% Nehalem= 1.56 + 10% SandyBridge= 1.73 + 4% IvyBridge=1.79 +10% Haswell=1.97 +4% Broadwell=2.05 +10% Skylake = 2.26 +17% Sunny Cove = 2.64 +19% Golden Cove = 3.14
