That's why Apple went to the RISC PowerPC in the not too distant past as
it could crank out more work than its Intel brethern. Unfortunatly it
eventually lost its lead and Apple had to make another migration to the
Intel platform. In some ways, that made things easier with virtual
machines and shared architectures under the hood. It's funny now to read
about how the PowerMac G4 was banned from export because it was
considered a supercomputer.

First, the number in front of the CPU is basically meaningless. The gigahertz
number is just the frequency of the master clock. There used to be a time
where this had some meaning. Chips were similar and one with a faster clock
rate should in theory compute faster but that isn’t really the case any more.
Different instruction sets, cache sizes, pipelines, number of cores,
word length, and on and on really are the factors. A much better measurement
is flops or floating point operations per second. There are other bench mark
standards as well but the basic idea is it’s more meaningful to actually
measure the amount of data computed rather than the rate of the oscillator.
The way that multiprocessing used to be done is that say two processors
would be set up in parallel and each would trigger by either the positive or
negative of the wave form. When the sine wave went negative it might trip
processor A and when it went 180 degrees out of phase to the positive it would
trip the other. The Fairlight CMI II was a good example of a computer that
works this way.
Now there’s all sorts of things happening with multiple processors per
dye, possibly multiple processor chips per computer each with it’s own set of
cores. A Dec Alpha chip in the old days at 400 MHZ smoked the hell out of a
Pentium at 900 MHZ because of the differences in the instruction set. If you
want to see a discussion on benchmarking and FLOPS I’d highly suggest a trip
over to top500.org. It’s a fascinating look at the top 500 largest super
computers in the unclassified space, their architecture and how each is
measured in performance.
Hope that clears it up a little.

Yes, not sure how much the CPU speed number really means these days. It seems
that with the airs being in the 1.5 ghz range, are they really faster than
something, say, like an old 2008 Mac Book that had around a 2.3 or 2.4 gig
chip? I know we have more cores and hyperthreading now, but if we didn't care
that much about having the thinnest thing around, would we be better off
getting the regular Mac Book?

A TB SSD would probably be a bit thick althoughI suppose you can wire the chips
in any physical configuration you want. It’s not like the old IBM 990K where
you had to have non 90 degree turns in the wiring so the electrons wouldn’t
over heat at the turns and cause to much thermal noise.
Biggest problem with your proposed config would probably be battery drain but
give it a few years. We’ll have way more than that in the form factor you want.

Yeahscott,
My perfect machine would be an 11inch mac book air with I7 quad core processor
and at least 32 gig ram with a 1tb ssd harddrive.
I like the size of the machine, the work time is great and the size is easy to
fit in a bag if I'm mobile.
But I can't run the things I really want to run at one time.
Ok so that type of processor and amount of ram would probably melt the keyboard
but surely they could put better heat disapation into the design.

This is one area I have issues with apple. Especially in the pro line I wish
they would support more than 16GB. As someone who likes to spin up a lot of
VSRX instances, it would be nice to have lots of extra memory.
Sure, I could get a Mac Pro and slap in a pile of cores and ram but I suspect
I’m not throwing that in my work bag.:)

The 13 inch mac book air with 8 gig ram and 512 gig ssd is a great
machine, No mac pros now have the optical drive unless you get the older model
which there is only one model of.
The standard is a retina screan so higher resolution and the
harddrives in the pros now are ssd So although the air can do what the
pro does, the air only currently goes to 8gig ram, and 512 gb ssd, the 13 inch
retina can give you up to 16 GIG ram and 1TB SSD But if your not doing anything
like major multimedia productions or editing then you shouldbe able to get away
with the air up speced.
Hope that helps.

my brother just got an iPad pro and is really impressed with the processing
speed and quality of the sound. I don't need a larger screen obviously. but
sometimes I need to display images or video so someone can help me sort them
for use on my website. that is why I'm settled on a 13 inch screen or there
abouts. thinking of a mac book pro and just dropping the cd rom to lose a
little of the weight. another thing i'm sure of is this time I'm maxing out the
ram and going with a SSD or compact flash hard drive. thanks, max On Jul 9,

sorry just assumed the air came in a 13 or close to that. what is the max hard

their cloud drive? thanks, max On Jul 8, 2016, at 8:59 PM, Christopher-Mark

I've never heard of an Air let alone any IPad model that is a 13 inch. Did I
miss something obvious?

Was decided on a mac book air 13 inch until talking with my brother.
He was going on and on abut the new iPad pro 13 inch. He said that
with the blue tooth keyboard it comes with it can do just about
everything you need. Have any of you had your hands on the new iPad
pro? If you could only pick one would you go with a mac book pro,
mac book air, or iPad pro? Thanks, Max
