OK, let's point out some of the biggest deficiencies in Matt's nonsense...

The POWER8 has the same register design as Apollo Core, i.e. integer registers and wide SIMD registers are the same. The POWER8 runs at 5 GHz and is at the time of writing the fastest processor in the world. So you are wrong with your claim "slows down a critical path". Reality proves you wrong which is something that even non-tech savvy people should understand.

Did I mention already that Gunnar took part in designing the POWER8? Matt, remind us, which real-world CPU did you help design?
