New Workstation Spec: Cores Vs Processor Speed

First, most of the work in 3D modeling os done on the Graphics processor, which can be compared to the old school "array transform processor".

For almost every other problem, faster CPU clock wins the battle. Taking a single-threaded problem and turning it automatically into a multi-threaded solution is a classic unsolved problem in Computer science. To get a really strong boost requires manually breaking into multiple tasks and hand-tuning to the number of cores available.

In general "More than a handful (of processors) is wasted". In general only special-purpose Apps like Compressor, (when properly tuned to the number of compute cores available) can strongly benefit from more cores.

The reason we are offered more cores is that CPU development has hit a wall. The only way to make it go faster is to go wider, as in more processor cores. This is not a solution anyone has asked for, it is simply the only known way forward.
