Hey! Octo-Core Mac Pros are on Apple Store! + Analysis

Apple - Mac Pro - Performance
Quickie as I gotta get out the door:
These are pretty much exactly the same as the existing Mac Pros, but with up to a pair of 3.0 GHz Quad Core processors.
Same graphics card options, same hard drive options, same EVERYTHING from my quick skim so far, just swapped out processors.
PERFORMANCE
Speed improvements for FCP don't look stunning...YET. UPDATE: Well, that's what I get for blogging in 3 minutes heading out the door for a meeting. The Quad Core 3.0 GHz Macs are 1.4x faster for FCP rendering than my Quad G5....but that is Quad Core TOTAL, not Quad core PER PROCESSOR - so I misread the stats - these stats appear to be for the OLDER machines (that have been shipping), they haven't released stats for the newer machines it would appear - but their phrasing is ambiguous and confusing.
BUT....that said, they DO have stats up for Maya 8.5 (the chart at top of article), and it is 2.6 times faster than my Quad Core G5. THAT is the kind of improvement that makes it worth upgrading a system for!
Photoshop CS2 stats are actually SLOWER than Quad G5 for many tests, since Photoshop CS3 (first Intel native version) stats haven't been released yet. CS3 stats will be very interesting to see, along with After Effects & Premiere Pro and H.264/MPEG-2 Adobe encoding options when the time comes.
PRICE
Dual 2.66 (with dual core processors, same as has been available) starts at $2500, dropping to 2.0 GHz shaves $300, bumping up to 3.0 GHz dual core adds $800, and the new option, the Quad Core 3.0 GHz is $4K.
AVAILABILITY
A BTO Octo-Mac the Apple Store claims will ship by April 9-11, a stock Octo-Mac 3.0 GHz config claims it'll ship by the same date - it would appear 8 cores is a BTO no matter what, and doesn't affect shipping dates if you customize from there. But shipping promptly - that's just 5-7 days from now for orders placed today.
Built the way I'd want it, an Octo-Mac would be over $5K before I put more goodies in it.
If I were building a new station, it'd cost about $7700 plus more RAM, RAID & AJA or BMD gear. Toys do add up quickly...
TAKEAWAY
Hmmph, not entirely impressed (YET):
-expensive for Quad Core processor option ($1500 more over Dual Core 2.66 processor option)
-not demonstrably cost justifying (YET) at this price point for what I want to use it for - I'll need to see the next Final Cut Studio running on it to say for sure...and we don't know yet when that'll ship. Maya stat shows promise though.
-no Blu-ray nor HD-DVD reader let alone burner
-no new graphics
-no new chassis
-no new nuthin' but the processors
The box IS fast for 8-core optimized apps, of which there are few as yet, Maya 8.5 being an excellent example. But I'd been hoping for Blu-ray and/or HD-DVD burners, better graphics card options, etc. Since Apple released this product now, 10 days before the pre-NAB press event, implies that they won't be changing the hardware for NAB - otherwise they would have just waited. By pre-announcing it, they get over the hump of "Hooray! Wait....that isn't so great...", and can just roll with the new software features as the Big Deal.
I'm going to wait for NAB to see what new software (that I'd use) can do on these. I'd been waiting for 2nd gen Mac Pros, this doesn't quite count in my book.
Color me not quite sufficiently impressed as yet - while the Maya stat is compelling, for me THE apps are going to be Adobe's CS3 suite (the video stuff and Photoshop), and Final Cut XXX, whatever they call the next version. Beyond that, everything else is gravy for my needs. Oh! And throw Redcine (Red's footage processing app) on that list as well of things I'm VERY interested to know how 4 vs 8 processors do.
My attitude may well change when I see Adobe CS3 and Final Cut Studio 6 run on this box, and we see stats for all 8 cores on some software. Oh! And for software that I care about and use, not some app not used for video tasks. One CANNOT linearly extrapolate "Well Maya 8.5 now runs 2.6 times faster on Octo-Macs than on a Quad G5, so Final Cut Studio wil RULE on these!" - it is NOT guaranteed to work that way. Some types of tasks break down for faster rendering than others, some do not. Even given that, it is up to the developers to take maximum advantage of the hardware available to them - for instance, my Quad 2.5 GHz G5 when running Compressor tops out around 220% CPU utilization, while my Dual 2.5 GHz G5 tops out around 175%. That means the Quad is running about 25% faster with twice as many processor cores available - not a hugely compelling gain. I'm HOPING that Apple will have done substantial processor optimization for the Intel chipsets with the new version, but we'll have to wait and see.
This also makes me think it'll be late summer or fall before we see a truly new, 2nd gen Mac Pro enclosure/motherboard at the SOONEST. Apple has been shipping the current enclosure, with minor modifications, for several years now. My Dual 2.0 GHz G5 looks pretty much the same at a casual glance as compared to one of these new Mac Pros, even though there are substantial internal differences.
I expect/hope to be able to revise my estimation WAY up as of two Sundays from now after the Apple press event at NAB (yes I'll be there). But for now, I'm not putting my own money down until I know what's up.

PS - my earlier "not so impressed" comments were based on a misreading of Apple's stats - I saw "Quad Core" in the Final Cut section and thought they meant Quad Core per processor, not per machine total. My bad.
UPDATE - just posted some Analysis & Tea Leaf reading on what this all means
Comments:
most of the benchmarks including FCP don't reflect the 8 processor mac pro just the quad. The ones that are updated show the octo in yellow. The quad 3 is what is 1.4x faster.
Exactly. The Maya software (tested in March '07) is the best indication right now of what to expect on FCP and other software-- 2 to 3 times faster. Not too shabby.
Mike, Mike...
The older tests that you saw, dated July 2006, didn't include the 8-core. The new tests in the 3D section are dated March 2007, and include the 8 core system.
AND IT FLIES!
Apple should update all the tests. They also don't have the new Intel native Adobe software in their tests. The older Adobe software runs in emulation mode and is even slower on the 2.66 Intel than on the Quad G5.

I think these will turn out good value for money. We have got to be expecting a multi-core optimised FCS and QT come NAB.
I'd like to be able to do a MAYA render in the background using 4 cores and be knocking something up in Motion with the other 4 cores...
I hope motion gets a tracker and some 3d and I'll be well happy. But I shall be waiting for Leopard before shelling out on a 8 core Mac Pro.

I wouldn't say no apps out there can take advantadge of that processing power. I regualary peg all 4 of my procs on my intel using shake 390%. It greatly depends on what you're using but so many of the new vfx techs are already really scaled for multiple processors. Its the software that we're al wating on to catch up.
Nice ..glad to see that the Octo Mac Pros are out in the wild so that Apple can focus on the Pro apps on the 15th. All these benches are going to improve once Leopard comes out. In fact I'd love to see Apple demo the nextgen Pro apps on a build of Leopard. They've done a bit of work on Leopard so that managing the prioritation of some functions is easier than ever. Plus with a threaded OpenGL 2.1 we should see large speed gains there as well. I look for the 8-core stuff to pull away from the 4-core stuff a bit easier then.
And it always depends how one uses the software as well. For example, it could be possible to run multiple instances at the same time for different parts of a project, a la:
Core 1: Do the frames 0-50
Core 2: Do the frames 51-100
... and so on.
In fact, there are events where you are better off not to use multithreading, for instance with Maya and mental ray. Some operations may not be threaded, thus launching 8 instances that are single threaded can be a better alternative.

The fastest Quadcore Xeon CPU that Intel sells is the X5355, with a 1333 MHz bus, and it runs at 2.66 GHz.
So what CPU's are apple using in their 3G Hz 8 core system?
They must be getting unreleased CPU's from Intel!
