But as you said yourself in an earlier thread a lot of compilation
isn't massively parallel so massive amount of cores for building isn't
necessarily as much a win as pure GHz. On that front the current A15
gen which is arriving now easily does the 2.5 - 3 ghz that the intel
platforms do (yes, I know they go to 3.6 but they're not regularly
used primarily due to heat) and most of the recent wins on Intel
architecture has been for media related things through various SSE
versions and other offload functions for things like crypto all of
which aren't massively used in standard compilation and all of which
have similar functionality on ARM platforms.
Speed is not GHz alone, but:
clock frequency (GHz)
/ cycles per instruction (a)
/ instructions needed to do the job (b)
ARM being a RISC architecture, it does great on (a), but not so great on
(b), and without knowing the exact factors, comparing GHz to GHz is
comparing apples to oranges.
