Aha, so your using personal bias against an architecture?
And your mixing different system hardware components and want to enforce the same naming convention.
Btw I would be careful using the term "cores" and instead talk about SIMD units and FPUs.
Global node bandwidth is cute, but a majority of applications benefit from a high localized bandwidth. 51.2 is a small fraction of 250+ .
