Leopard Under The Hood And Requirements Analysis

Leopard (Last PPC OS)

I bet this is the last version to support PPC. Universal apps will eventually disappear and one of the new secret 300 features for 10.6 is that the binaries are smaller and uses less memory.

I completely agree! I don't see how a 32 bit intel can out pace a 64 bit loaded G5 tower!? :eek:

I hope this little chart isn't the whole truth.

Well, to start with the Core Duo, Core 2 Duo and Xeon processors are all 64-Bit. Then you toss in the fact they they are more advanced and has the SSE, SSE2,SSE3 & SSE4 instructions for dealing with A/V processing....

So no Photobooth backdrops for G4s or G5s? I somehow have a hard time believing that my G5 Quad can't handle a backdrop.

I believe :apple: is covering there arse incase someone with a G5 says the backdrop feature does not run, and then get slapped with a class-action lawsuit. ;)

It might work, you have nothing to lose. :)

I asked this before but no one answered. Apple says the 800MHz machines are too slow, so why are the 867's okay? What kind of difference does 67MHz make?
Click to expand...

Apparently 67MHz does make a big difference to :apple:. :D

9 gigs!???
Click to expand...

9 gigs sounds more of a deafault/easy install, I am sure once you custom the install it will be around 5-6 gigs. Its mainly all those extra languages. :)

What were the 'secret' features Jobs mentioned last year? I've lost track!
Click to expand...

Pick any of the 300+ features that were not mentioned in the Keynote and those my friend are the top secret features. :D

But why is it 9 gigs? What in the world did they do to the OS?:eek:
Click to expand...

Well, it supports 4 different processors.

G4 (PPC 32Bit)
G5 (PPC 64Bit)
Intel 32Bit
Intel 64Bit

Though I'm not sure why they need the Intel 32Bit support as all of the Intel CPU's support 64Bit processing. Note from the moderator: This comment generated a number of replies correcting the statement (see below). Please don't post the same correction yet again.

So, that accounts for 2~4 gigs... (at least that was xslimmer comes up with)

Then you add in all the extra languages and the amount of new hardware it supports..

Maybe :apple: included a 32 bit PPC/x86 , 64 bit PPC/x86 version along with language localization. :)

exactly what I just said... just more concise.

9 Gigs... Why is this alot?

There are hard drives now that are 1TB large. Why is 9GB such a concern?
Click to expand...

Yeh but fast laptop HDDs stop at 200 gb, and if you use a laptop for your main machine like me, then you're already pretty pushed for space...

Unless Apple changed things Front Row will run.It's now an app in the applications folder.

Command-Escape

Or you can use your iPhone if you have one! I hacked frontrow on my 1G G5 and use my iPhone to control it. :D

If I stand corrected, I believe the Core Duo were 32 bit processors. I remember people were complaining if it was wise to go with the Core 2 Duo or buy an older Core Duo due to the 32/64 bit situation. :)

People have been using the WiiMotes as well. I am sure 3rd Party BlueTooth remotes will work as well. :)

Why do you say this? Do you know anything technical about the processors?

Intel Processors use SSE, SSE2, and SSE3. Advanced instructions for multi-media. How do you know that these backdrops arent coded heavly with SSE? Thus, Making the G4/G5 unable to execute these tasks.
Click to expand...

I'll admit I'm not a code junky, maybe you are. But if it is true that Apple could only have made the whole backdrops work with SSE then I think that they need to go back to the drawing board. This is the company that has long been able to simplify things and make it work, I can't see them making this so dependent on one processors abilities, although I can see the economic reasons for this.

I'm not whining that it won't work, I can for sure use the function on my laptop, but I would think that a fairly new G5 would handle this using some other codes.

Surely non-IR macs can instead use the keyboard shortcuts for frontrow (apple-escape etc.) - little point without IR of course.
Click to expand...

IR was a terrible choice to begin with, it should have come with a BlueTooth remote, that way an IR sensor would not have been required thus cutting cost. :apple: is a mystery at times. :)

I always thought the original intels - plain old duos - weren't 64bit - the idea being that multi-cores were the way of the future. I thought that was why the core2duos were such a 'big' deal when they arrived. Anyway actually know for sure?!

I believe the major reason is $$$, if you want the feature :apple: is forcing you unintentionally to upgrade your hardware to run it. I personally have a 2GHz G5 and a 2.4GHz SR and could care less for the feature. Its amusing, fun and exciting at first however like PhotoBooth visual effects it gets old pretty fast. :)

They had to draw the line somewhere and I'm sure the 867MHz would be just as bad as the 800MHz.

Core Duo processors and Core Solo processors are both 32 bit. Only Core 2 and Xeon are 64 bit.

Well Intel makes it alot easier to code new progams with software they offer for developers. Multimedia programs are now heavly coded with SSE etc making it much much simpler to code for. Many of the SSE instructions combine 2 or more instructions into one SSE instruction. Im sure the G5 is "Fast Enough" however it may not process the right code. Many of these new programs are fairly complex. What this sounds like to me is that this "Backdrop" thing is so complicated, once it was coded for with an Intel System, They would have to recode the entire program just to run on the PPC architecture. Im sure it could have been done, but im also sure that it would have taken alot more time.

If apple could, im sure they would drop PPC support all together, and just build Intel only (x86) code from now on. They wouldn't look too good, but it would be easier and save alot of R&D $ to code for both architectures.
 
If I'm reading the chart correctly, Leopard will run on my PB G4 1.33 GHz, but DVD player won't work? Or is the earlier poster correct when they say that only the advanced interleaving won't work? I'm a bit confused on that one!

You've heard of laptops? The basic Macbook has an 80g drive. 9g for the OS, 15% for system swap files (which I always leave empty) and that's only 59g left.

This is bloatware. I sincerely hope that I will have the choice to leave a lot of this stuff out on install.

Apple has developed the Accelerate Framework, where one of its specific advantages is that it can run on both Altivec (for PPC) and SSE* (for Intel) without architecture-specific commands.
