Yeah, right. The Mac *IS* the sum of its parts. I haven't seen any
halo over my PowerBook lately.
Getting back to the topic, somebody asked about a speed bump. Take a
look at the hardware releases in the PowerBook line since Apple
clocked the bus up to 167 Mhz. All they've basically done, besides
different drive and graphics options et al, is increase processor
clock - bump the voltage on the core which increases power
consumption with very marginal increases in performance. You clock a
cpu at 1 Ghz then increase its clock to 2 Ghz you don't double the
machine's performance. The real speed bumps happen in system
architecture. The 32-bit PowerPC processor has been developed
*waaaay* beyond what's in the PowerBook G4. Dual core, in fact, with
a built in memory and network controller - truly cutting edge stuff.
Stuff that Intel says they *might* have in 2007 when they released
their joke of a processor roadmap a couple days ago.
Nobody here wonders why that stuff never made it into the PowerBook?
Minimum cost spent on engineering and development, milking an
existing logicboard design for all it's worth, and cheapening up the
processor in order to clock it faster. That's what a modern
PowerBook consists of. The *real* technology and performance is in
the dual core 32-bit processor manufactured by Freescale. This
processor integrates two e600 PowerPC cores, dual 64b DDR2, >533MHz
ECC memory controllers, dual ethernet controllers, a RapidIO™ fabric
interface, dual PCI Express, x1/x2/x4/x8, 2.0Gb/s per lane, 90nm SOI
process, operates at a core voltage of 1.1VDC, full AltiVec support,
and a high performance MPX 128-bit bus that scales to 667 MHz. It
outperforms the single core PowerPC970 (G5) running at 2.7 GHz hands
down and only pulls 15 watts per core at 1.5 GHz clock. I have one
laying on my desk in front of me. Those processors fit right into
the PowerBook, although they'd require a different logicboard
design. Will the PowerBook ever get them? Don't hold your breath.
Freescale will charge Apple double for those cpu's what they're going
for in the communications market after Apple went to IBM a couple
years ago, and now to Intel.
Freescale has gone to the linux operating system (http://
www.freescale.com/webapp/community.show_collateral.framework?
nodeId=0C0928905459414858&communityNodeId=0C0928) as a market for
these new processors, which is like 20+ times the size of Apple's
market. Apple don't have many bargaining chips left (pardon the
pun). They got to the bottom of the barrel, had no where to go, and
made too many enemies along the way. And *that's* the real reason
ya'll are running PowerBooks with 5-6 year old technology inside 'em.
