Scott, how do you see 64 bit chips benefiting audio? From
having worked in CPU architecture many years ago all I see
is a potential for requiring a higher data and instruction
bandwidth to accomplish the same work.

If and when there is a nonvolatile ram technology of
sufficient capacity I can see a gain but I feel it can only
benefit us now by forcing device scaling which may improve
the performance of the 32 bit subset of the architecture by
default and then only if that subset can operate without the
overhead penalty of supporting 64.

I can see 64 bit coefficients being a handy thing for some kinds of processing.
Then again, if you don't care about running realtime, there is no reason you
can't do 64 bit arithmetic with an 8-bit machine.

The other thing I see is that some of the machine with a 64 bit architecture
might have faster 32 bit floating point operations if stuff is put into the
ALUs to do simultaneous halfword operations. The SPARC 3 did this and it was
a slight win.

ONCE in over 2 years I've been using it, day to day.

thats great! my dell inspiron crashes daily...blue screen. this has happened

but damn would i love to get my $'s back from hell dell.

The fact that being able to move data in 64 bit chunks is an enormous win
if you are doing 64 bit arithmetic, and that can be a big deal for some
stuff. Code that ran in double precision mode now runs in single, with
a considerable speed improvement.

But the 32-64 jump isn't going to be anywhere near as big as the 16-32
jump was, just because there is less of a need to do that for typical
applications.

The wider data word also allows a big improvement in the speed of block
operations, where you're moving arrays from place to place in memory,
since you can now do it in 64 bit chunks.

And if you are really good, or your compiler is really good, you can do
things like store adjacent 32 bit values into a single 64 bit word and
then use 64 bit operations to load and store them both at the same time.
This is less of a win than it might seem at first.

But address space is the least of your worries.

For audio it offers almost no perceivable benefit. For
calculation we just don't need it and wider busses for the
more rapid movement of blocks of data don't require 64 bit
integer architectures. Busses wider than 32 bits have been
around for a very long time for the purposes of higher
memory bandwidth.

Not on your respective machines apparently. That's OK. My Win2k system
doesn't crash either, but then again neither did my Win98 system, nor my
Win95 system, nor even my old Windows 3.11 system. Properly configured
machines really shouldn't crash.

But I'll be totally honest. I simply don't remember any crashes on Win 3.11
or 95. Could be that they did, but it apparently didn't register so they
weren't catastrophic and I was even doing beta testing on both of them.
However, Win2k has been on this system for a few years now and it runs day
in and day out unless we have local thunderstorms.

Don't feel bad. For years my older son couldn't touch a computer without

Personally I don't know what all the "fear" is in a Mac user contemplating a
PC or vice versa. It's just a tool, and like any tool the use is mostly
dependant upon the application. Obviously anyone looking to buy a new
computer today should look at the application they wish to run and buy the
appropriate platform, and buy the best damned one they can afford. I'd
rather opt for stability and reliability over a period of 18+ months (almost
getting to be an unrealistic requirement anymore) than upgradability.

This system is on it's last 6 months at the Athlon 1600+ level and already
there are now 3200+ CPUs. But with multiple SCSI cards (2940 and a
fibrechannel), 180 gigs, dual head, etc., I won't necessarily be upgrading
until I really find it necessary.

At least the new G5 looks to be a solid machine. Were I inclined to move to
Pro Tools it wouldn't concern me the least in making the move to a Mac.

It doesn't get lost. It's just one of several factors.

What OS someone prefers is up to them. Some might choose Apple... some MS.
The performance and price relationships are still important to those not
absolutely determined to use one OS or the other (as in... Nuendo or
CubaseSX users, where OS has little impact on how the app functions).

The obvious speed advantage comes from addressable memory. Unless a quatum
leap in hd speeds hits inexpensively, the current bottleneck of hard disk
access is going to play an even more significant part. And I don't mean
faster bussing, although that plays a part. I mean pure raw writing and
reading speed. So by virtue of having huge improvement in addressable
space, memory becomes the arena whereby any reasonable improvements in
system speed will be seen initially. With something like Samplitude, and
it's ability to do full multitrack recordings in memory, I could easily see
having 10s of gigs of memory and a system with the responsiveness the likes
of which have yet to be seen.

The new Opteron that Scott Reams keeps talking about has up to 19.2 GB/s of
bus speed, which means a lot of memory would be an ideal condition to use
for recording. Couple it with a VERY IMPORTANT UPS and one could have a
tremendous system, not unlike AT&T's ridiculously expensive DISC system.

Now if IBM could just get that holographic memory down pat and put out an
inexpensive blue laser setup, we could afford the terabytes of memory we are
all going to need to have! g

Well, there would be speed advantages by offering huge amounts of
addressable memory space. Instant track bouncing, no pre-loaded caching,
instantiations of plugins that simply sit there waiting without crapping out
a cpu. Little things like that! g

Isn't it ridiculous that what was perceived as a major advantage just a
couple of years ago is now a time waster! g

Your memory is volatile. :-)

In my first post on the subject I said:

If and when there is a nonvolatile ram technology of
sufficient capacity I can see a gain but I feel it can only
benefit us now by forcing device scaling which may improve
the performance of the 32 bit subset of the architecture by
default and then only if that subset can operate without the
overhead penalty of supporting 64.

So I concur on the benefit that will occur _when_ abundant
ram is available to capitalize on the large address space.
I add the qualification that it be non-volatile, and I guess
some would take issue with that, but I just wouldn't count
on its presence when it can so easily be lost.

Hank, you can talk (but no video obviously) with a dial up connection,
which ain't bad.

One thing to note about the new Apple camera, the iChat software it
uses take the video and audio and auto enhances it. Which is damn cool.


Jobs a/b 'ed it with the best current Mac videocam, the iBot which btw
doesn't cost $39, its $99 and it comes with no mic, and the Apple
product killed it. Which, unfortunately for developers of cheap
videocams, is really bad news.

Remember, Jobs bought Pixar 15 years ago and has been very successful
running it. Think he knows a little about using video and computers?

The Apple product may have been better... but lets look at who's doing the
a/b-ing.



A guy who is also CEO of Pixar. Think he knows anything about using
computers for video? Naa. He's from Apple. Apple = Bad.

One of the reasons it looks better is the Apple software autocorrects
the camera for the best picture. Really smart. And simple.

Jobs is head and shoulders above the entire computer industry today
when it comes to new stuff. The recent string of products and those to
arrive this year practically embarrass the rest of the industry. Is
anyone else putting out the cool stuff that is coming out of Apple
these days? Michael Dell? Carly Fiorina? Ted Waitt? Craig Barrett?

Heck, Bill Gates is spending a good bit of his energy creating a
special watch to stay connected. Just what I want to do, look at a tiny
thing like a watch for a user interface. You know anyone besides Gates
clamoring for a Dick Tracy watch to stay in touch with their messages
or the internet?

Despite the Bill's many billions, his zipcode is still Nerdland. And he
still has that billg hairdo. Think he'll ever notice his head has hair?

I'm sure Jobs is quite capable of assessing the quality of a video camera.
That isn't the point.

It has nothing to do with "Apple=bad", and everything to do with the fact
that you never, ever trust comparisons made by the company selling the
product. Period. I never consider benchmark results posted at Intel, AMD,
