The prevalence of multithreaded code is server and workstation environments make the frequency difference extremely important, especially when it comes to the types of workloads that have frequent memory delays and accesses.
If it happens in a core as part of the logic or caches, that core can be fused off and the die can sold as a lower core part.

If that is not enough cores, then you can pick up an eight-socket motherboard and load it up with multiple of these.
While Ivy Bridge-EX was available with up to 15 physical cores per processor, double that with HyperThreading, Haswell-EX is increasing that to 18, or 36 simultaneous threads with HyperThreading.

This chart shows how an aggressor VM can start to degrade performance until cache monitoring detects this, partitions the cache, and restores packet performance.
The core will slow during the execution of the AVX instruction in order to maintain TDP limits, which may cause the frequency to drop.

For a workstation or server builder, in the 2S market, Haswell-EP offers an unmatched combination of performance and features.
Obviously the efficiency improvements that you get with AVX code will more than make up for the clock speed differences.
