Great article, one of those occasions when I read, sit back, slap my head and say out loud “Ah, yes, now it all makes sense!”

Posting here for the same reason as retnuh. D’ya think maybe you could work out an e-authentication mechanism where AppleInsider trusts any user logged into RoughlyDrafted? Oh well, that said…

I have a 3.2 GHz Mac Pro with 32 GB of RAM and 4 hard drives totaling over 3 TB of disk space. When I tell people this, I universally get appalled looks and asked “What could you POSSIBLY use that much memory for????”

The answer, of course, is video. I’m the video librarian for my state-level martial arts association, and I have to tell you, nothing eats up computer capacity like video.

Despite all of my hardware, it took over an hour and 45 minutes to compress a one hour video to 4.7 GB DVDs using iDVD 7.0.1. That’s part of the iLife ‘08 suite. I have FCP Studio, but I thought I’d just do a “quick-and-dirty” DVD using iDVD. It was anything but quick.

So my comments about the AppleInsider article are these:

(1) You didn’t even mention video as a reason to expand 64 bit support. Compared to video, Photoshop doesn’t even exist.

(2) Where we’re REALLY going to benefit will be more easily using multiple cores, provided that apps don’t run into stability problems due to concurrency. I assume you’re going to cover those Snow Leopard improvements in a later article, right?

(3) Finally, and this is for Apple, not for you, it would be REALLY helpful if Get Info on an app told me what kind of an app it is in terms of memory usage. iDVD and DVD Studio Pro both just say “Application”. If one is 32 bit and the other 64 bit, I would obviously use the one that’s 64 bit, but not if I can’t tell. The OS knows. The OS should tell me.

Good article, Prince.

Since I’m tired and so I’m not going to create a appleinsider login for this comment.

One glaring problem is the focus on the x86’s 8 GPRs. Register renaming took care of that in the Pentium Pro and its only gotten better since, mainly Core 2 Duo handling better/more cases to rename.

A modern x86 cpu has a lot more internal GPRs than what the ISA exposes to the outside and while your point was valid for older processors its just not really an issue on the newer x86-64 which is why they only went to 16 GPRs. Register renaming is a huge reason that big fancy instruction decoding stage that finds interdependent instructions exists.

Now you can argue that OoOE designs use more power than inorder, but they generally get more work done and overall its a design win.
