On top of that the 5400K has only 1MB L2 cache the 3670K has 4MB L2 cache.
Well first of it's not a single core and I don't think like it is one. It's not one core.
It's two cores that share the front end.
The Fetch is only single to the module front end, the retire/execute is dual.
The sharing front end isn't as bad a the original FX was I've have an FX 8120 which showed it's shared front end problem, when two cores in use. Where slowed down by 32% at most. Trinity cores don't show this big a difference anymore.
Cache wise, less would probably end being better for the Design of the new architecture, Cache misses go back to main memory for congruency. Having to go threw a large L2 cache and L3 cache would only make the latency rise, and makes the misses even worse.
