Is having more cores more energy efficient than having one big fat ass 24Ghz processor? Maybe thats a factor in the increasing core count.
But as some already pointed out, many applications can't use multiple cores, therefore you won't get any performance improvements with multi cores.

congrats..but why would anyone pay 425$ for a 3GS/32 when most can get the iPhone discount for a 4G for 74$ more?..I have 3GS/32 black and Im going to keep mine for a back-up phone/iPod/maybe sell it later/ and I'm getting the $499 discount since I'm not eligible for an upgrade til 3/11...glta
You got great price, me too sold my 3GS 32G less then one year old in mint condition got only $400

My main interest is in FCP the FCP results.
On a fixed budget, does anyone know the advantage/disadvantage of going for the 2.0Ghz with 1900XT over 2.6Ghz with the std video card?
I think movie editing depends a lot on the speed of the disk subsystem. After all Mini DV is 12GB per hour. That's a of data. When yo "scrub" a shot all that data has to move off the disk and onto the video card. Even with 16MB of RAM not much of the video data can be help in RAM. So the G5 and Intel machine have disks that are about the same speed. Speed of a disk is measured by how fast the bit fly under the read/write head not the interface speed. So I am not surprized the Intel Mac Pro is not hugly faster for video.

Speaking as someone whose iMac G5 has been out of commission and in the nearby Apple Store for thirty days (!), I'm not the happiest Apple user, either. Thing is, I've only ever had good experiences, prior to this. For example, I had one of the early Apple Studio Displays (the ones that looked like oversized bondi blue iMacs), and when it started wonking out, Apple sent me a box, shipping label pre-printed, and repaired it for free, even after it was out of warranty (there was a known defect.)
This latest episode has been pretty aggravating, though (although the only saving grace is that I'll likely be able to score an Intel iMac out of the deal, which I'm somewhat excited about.)
Heh, maybe I should have the Apple Store twiddle their thumbs for a few more weeks, and I might be able to grab a Core 2 Duo version. :P

You obviously missed the point that they do not track anything. It's just a log file on your iphone, it stays with your iphone. I GOT even more news!! I FOUND a file on the iphone that stores text messages. YES PEOPLE text messages. I can read your text messages from this file if I have your phone!! Oh ya, I know you can launch the SMS app, but WHY WOULD APPLE NEED TO STORE TEXT MESSAGES ON MY DEVICE?!?! I'm suing!!
Just like web caching, storing text messages is part of the function of the messaging app. It serves a purpose of giving YOU a history.
And guess what... you can clear it. ;)

I'm not a birther. But I would love to know why the certificate looks new when the president is nearly 50. Now I'm about five months older than he, my original birth certificate has faded. The certificate he produced clearly isn't the original. Or if it is the original, it's astoundingly well-preserved.
He hasn't been carrying this around for 50 years. Did you actually read the article?
The White House also released a letter from the president on April 22 requesting two certified copies of his original certificate of live birth. Also released was a letter from Loretta Fuddy, Hawaii's director of health, approving the request.
The president's personal counsel, Judith Corley, traveled to Hawaii to pick up the documents and carried them back to Washington on a plane. The documents arrived at the White House around 5 p.m. Tuesday.

[QUOTE=jicon]Lots of stuff on Anandtech about the poor memory performance on the Intel chipset./QUOTE]
FB Dimms are not designed to give maximum bandwidth to one chip, they are designed to give maximum bandwidth to _four_ cores. Instead of having _one_ program running to test memory bandwidth, they should have started four copies of it and see what happens. That is what you have doubled front side bus, buffered memory and two separate memory units for. The biggest criticism in the past against Intel multi-CPU systems was that the memory bandwidth didn't scale; in the Mac Pro, it does.

I don't like Adobe anymore. :mad:
I dunno, I mean, I guess they could use core image, but really. CS3 will probably have PS, Illustrator, ID, FW, Flash, DW, CF, Contribute, Bridge and Acrobat. That's 10 apps. Would you want to develop 20 apps, just so that Mac users could have Core Image? Until competitors come along with Core Image support, don't expect Adobe to have it.

What I'm asking is, does it justify the action that we're taking?
That, I'm not sold on.
I'm willing to accept the current level of US involvment, provided it is short-term and really is part of a broader coalition with UN backing. Whether it turns out to be justified depends on subsequent events.

Do you think a Conroe iMac will beat a Mac Pro due to lower memory latency alone? Do you have real experience or data regarding how horrendous a problem this is? Extra dual-core processor aside, the Mac Pro has a higher speed FSB, higher memory bus bandwidth, higher RAM capacity, and ability to set up internal RAID amongst other advantages over a Conroe iMac.
Obviously, inherently the iMac design is inferior to the Mac Pro/Powermac. But I think there's a bigger reason why Apple chose to go all quad with the Mac Pro: Apple chose all quad because a duo option would have had the same performance in professional apps (again, excluding handbrake and toast which are the only two examples touted about). A single processor Woodcrest or Conroe option will have the same obtainable CPU power for 90-95% of the professional market for another 6-12 months at the very least.
Here's some data regarding the Mac Pro's FSB:
the Mac Pro (...) actually takes longer to access main memory than the Core Duo processor in the MacBook Pro. This is much worse than it sounds once you take into account the fact that the MacBook Pro features a 667MHz FSB compared to the 1333MHz FSB (per chip) used in the Mac Pro.
What can we take from this? Because of the use of FB-DIMMs, the Mac Pro's effective FSB is that of ~640MHz DDR2 system.
And how does it fare in memory latency?
It's not Apple's fault, but FB-DIMMs absolutely kill memory latency; even running in quad channel mode, the FB-DIMM equipped Mac Pro takes 45% more time to access memory than our DDR2 equipped test bed at the same memory frequency.
As for bandwidth, although the Mac Pro has a load of theoretical bandwidth, the efficiency is an abysmal 20%. In real use a DDR2 system has 72% more usable bandwidth. (source here (http://www.anandtech.com/mac/showdoc.aspx?i=2816&p=11))
I don't know bout you, but if I were a heavy user of memory intensive apps such as Photoshop, I'd be worried. Worried in the sense that a Conroe would be noticeably faster.
Memory issues aside, Woodcrests are faster than Conroes, 2.4% on average (source here (http://www.anandtech.com/showdoc.aspx?i=2795&p=6))

I don't know how many times we have to go round and round with this here. I've been on MacRumors since '01 and it's always the same-old, same-old. It's not legitimate. It's "I-wantism." You have no basis to believe that a Rev B would be more "stabled and refined." That's a hope, backed by nothing -- and nothing Apple ever comments on, either. The bottom line is that you can hope if you want, and you can wait if you want, but to bash Apple for being slow on the trigger, and to make the argument that Meroms are amazing and Yonahs are crap is, frankly, horse manure. Like I said, 64 bit is pretty irrelevant for most users, and the speed and battery differences are quite negligible. And the argument that Apple is losing tons of sales to PC manufactuers is, frankly, laughable too.
Then please let those in here, myself included, make our own mistakes by buying the lastest iteration of the macbook pro. 'kay, thanks.
This isn't a "why are you waiting for rev-X." This is a thread about notebook refreshes and when they're going to happen.
That being said, I'm now waiting for Photokina. :)

Windows manages to run legacy apps still. Even if you do have to resort to using the virtual machine they've called 'XP Mode.'
Because Windows is bloatware. I don't want my Mac OS to be able to run **** 10 years old. This only hampers innovation by having to spend time making sure all the old stuff doesn't break. Move on my friend. I can probably use XP to print to a 15 year old dot matrix printer.

Some of the comments on this board are inane.
1) Launchpad is the selling point...Really? You think Versions, Resume, Mission Control, OS wide Full Screen App support are not selling points?
2) $129 is too much. This one cracks me up. Apple is bundling a $500 product into the OS (and other OS based servers are far more expensive) and people think $129 is too much?
3) When has Apple released an OS, and not shown new features on the final release keynote?
You thing the additional GUI enabled features in the Server version is worth $500? Others are more expensive because they are actual server class. Not a cheap bolt on.
All the "NEW" features are things that should have been preset since 10.2 at least.
Your clearly Apples ideal customer.

This was one of the advantages of the G5 but IBM stalled and Intel has essentially blown past everybody. AMD will answer no doubt, but it appears that Intel has about a 6 month jump on them.
AMD has it's hands full with an ATi take over which gives Intel the chance to get a bit a head on the Processor game. Either way it's good Intel has some real competition it means faster cheaper chips.:cool:

California, it's replies like this that pisses switchers off, even seasones mac users get upset with these replies. What the hell is Rev A?. What idiot argument is this?. That's it ok for apple to make a ****ed-up product cause it's the first version?. What?.. apple just started making computers that they don't know how to make quality products until they already made the first version?. Apple should be horrified at your suggestion. Imagine if no one bought Rev A (whatever the **** that means) machines from Apple. APPLE WOULD GO BROKE!!. There's always Rev A machines when it comes to computers dude. The next mac pro upgrade will use a new processor, faster, new video, more ram, newer harddrive and becomes rev A cause THEY ARE THE FIRST APPLE PRODUCTS TO USE THE NEW UPGRADED PROCESSOR, NEW HARDDIVE, ETC. Really, stop with this nonsense. You are like the 10th idiotic apple fan I have read using this dumb argument.
Let's make it clear. The first revision of any highly integrated system is produced with an acceptable failure rate. With results coming in, failures recorded and internal testing continuous between the life of the first and second revision you will see a drop in failures in the next revision.
Every item that is in the next revision will have been tested, more flaws removed, etc. No piece of hardware is released with zero defects. [human interference aside such as dropping the product, overheating it, intentionally forcing failure]
If for every 1000 systems shipped approximately 20 fail, after a minimum predicted total hours, this 2% attrition rate is highly desirable. If you can't accept it you can stop using technology, now.
For every ten people bitching on this board about failures there is over 1,000 that don't.

Oh - and one more thing: Apple better not send me a refund if they lower the price before the package hits my doorstep. :mad:
