    I'm waiting for a Hardware & Software upgrade as well, i want an iMac, just don't need one desperately right now. But i didn't get one thing: Does the iMac get Santa Rosa first and later this year the Penryn chips? Or is Penryn desktop/laptop only and the iMac sticks with Santa Rosa for a while?

    imac. 20" or 24". not urgent so i'll wait until june at least although it would be nice the sooner the better.



    might be interested in a widescreen ipod although i think it would have to have something else going from it since my 60gig video is fine and dandy still

    I have been a PC user since I started using a computer. I now hate Microsoft and am going to buy myself a octo-core Mac Pro. Cant wait. Hope they feature some new graphic cards at NAB though, been waiting for ages like the rest of you.

    I'm envious. Have fun with your new computer.

    I was...until I scored a 20" Core Duo iMac for $950 CAD locally

    Your sig says that you have a 20" 2Ghz Intel iMac... that's not possible, they start at 2.16 Ghz.

    Holding out for a second gen 8 core mac pro, blue ray would be nice, and i'm not sure how long i can sit on my money for that 30" monitor i've ben having at least one eye on for years. having seen it drop from 5 to 2 grand should be long enough, but who knows about that resolution and led backlit rumour...



    also hoping for an ultraprotable macbook or pro to replace my newton... ;-)

    If it's true that Leopard will come out with a major new OpenGL version (2.0 I suppose), and if it's further true that Leopard will be released around WWDC in June, I'd say any new high-end graphics card would probably wait for that too.



    They're not going to sell even nearly the numbers as for PC hence I doubt that whoever develops the drivers will develop one for OS X 10.4 (OpenGL 1.4) AND one for OS X 10.5 (OpenGL 2.0). They'd probably settle for one version only. And that would likely be the new one.

    Forgive my igornace but would the addition of Penryn make such a large difference to something like the MacPro over the current 8 core setup. As I said, I have waited till the octo came out. It is here no much has changed. I intend to buy but am not fussed over a few months. Sorry for the noob question. Thanks in advance.

    Newer, OpenGL 2.1

    Well, heres hoping.



    Need a laptop bad for the end of May when I will be travelling. In a perfect world, both the Macbook would be updated, and Leopard would be released by then.



    <crossing fingers>



    If just the Macbook is updated I'll still buy and bite the bullet on Leopard.



    Or if Leopard is released but the macbook isn't updated, I'll buy and bite the bullet on the book.



    We shall see. :-)

    OPenGL 2.1, and Leopard's LLVM info (Low Level Virtual Machine.)

    For those who are interested, Apple announced that they are using the LLVM

    optimizer and JIT within their Mac OS 10.5 'Leopard' OpenGL stack (which

    was distributed in beta form to WWDC attendees).



    LLVM is used in two different ways, at runtime:



    1. Runtime code specialization within the fixed-function vertex-processing

    pipeline. Basically, the OpenGL pipeline has many parameters (is fog

    enabled? do vertices have texture info? etc) which rarely change:

    executing the fully branchy code swamps the branch predictors and

    performs poorly. To solve this, the code is precompiled to LLVM .bc

    form, from which specializations of the code are made, optimized,

    and JIT compiled as they are needed at runtime.



    2. OpenGL vertex shaders are small programs written using a family of

    programming langauges with highly domain-specific features (e.g. dot

    product, texture lookup, etc). At runtime, the OpenGL stack translates

    vertex programs into LLVM form, runs LLVM optimizer passes and then JIT

    compiles the code.



    Both of these approaches make heavy use of manually vectorized code using

    SSE/Altivec intrinsics, and they use the LLVM x86-32/x86-64/ppc/ppc64

    targets. LLVM replaces existing special purpose JIT compilers built by

    the OpenGL team.



    LLVM is currently used when hardware support is disabled or when the

    current hardware does not support a feature requested by the user app.

    This happens most often on low-end graphics chips (e.g. integrated

    graphics), but can happen even with the high-end graphics when advanced

    capabilities are used.



    Like any good compiler, the only impact that LLVM has on the OpenGL stack

    is better performance (there are no user-visible knobs). However, if you

    sample a program using shark, you will occasionally see LLVM methods in

    the stack traces.



    Getting Anxious over here.

    The way I interpreted what onlooker just quoted is...



    The LLVM will govern what graphics effects get used and displayed by only switching on the effects the graphics card can handle, other effects get switched off, so that they aren't running and slowing the applications down for no reason.



    Kind of optimising the graphics output to the capability of the machine, right?? :s

    Onlooker,



    Please expand your post "Getting Anxious over here."

    Thanks,



    That is the expansion. I'm merely posting some documentation I found on items that are occurring in the current discussion.

    I'm Anxious to see leopard and even more Anxious to see OpenGL compete in areas that Direct X has been dominating. I didn't realize it was that difficult to understand. Sorry.

    I've been eyeballing the new Mac Pro and am holding off until NAB just incase there are new graphics cards, or new monitors revealed. If they don't give us any new GPU's I'll have to drop the cash for a Quadro FX 4500. I'd rather see newer offerings than what Apple offers.



    Just a few more days...

    I also found this review of the Octo-Mac Pro:

    REVIEW

    It causes me concern if they are talking about bottle necks. I'd like to hear what you all think about the review.

    If you're dealing with an app that requires a lot of memory swapping a la photoshop then the Octo isn't a huge update. If you're doing a lot of encoding or rendering then the Octo shows a marked improvement in speed.



    The problem right now is two fold.



    1. Apple doesn't have enough intelligence in their threading so that we have core affinity in Tiger. Threads will move to different procs when they should be be locked to a single proc/cache. Leopard will improve this



    2. Bensley, the chipset of current Mac Pro, has a snoop filter that only tracks two procs and the shared cache. When you move to a Quad Core system Bensely if inefficient in determining what goes where" beyond two procs. Stoakley/Seaburg and Penryn will fix this because Seaburg the controller will know "what goes where" for 4 procs with an improved snoop filter.



    If I needed power right now and I wasn't running heavy CPU bound stuff I'd qo Quad and skip the Penryn/SS architecture and wait for Nehalem to hit in late 2008 early 2009 before upgrading.
