Is it just me, or does terminology like
"55% faster" seem ambiguous or at least just plain funny?
We all know what it means, but it just sounds bad.
I'd rather just see people (Apple) say it runs as 1.55 times the speed.
This sounds to me like it could be interpreted as:
NEWSPEED = BASESPEED * 1.55 <<- what it must mean, I assume
(NEWSPEED - BASESPEED)/BASESPEED = .55
=> NEW = .55 BASE + BASE = 1.55 * BASE
(hey! consistent!)
(NEWSPEED - BASESPEED)/NEWSPEED = .55
=> NEW = .55 NEW + BASE => NEW = 2.22 BASE
<<- I wish, dream on
BASESPEED/NEWSPEED = 0.55 => NEWSPEED = 1.18 * BASESPEED
or even, 55% of the machine is (somewhat) faster, the rast is the
same, hence the total speedup is
(UTILIZATION OF THIS 45 % ) * 1.0 +
(UTULIZATION OF THIS 55 % ) * UNKNOWN_SPEEDUP_FACTOR
