Do you have any links that describe Merom's SpeedStep compared to Yonah's? I thought Yonah's was quite good, allowing you to reduce both clock speed and voltage simultaneously. It is always a problem with Intel, they say "improved SpeedStep", but they never tell you "improved compared to what".
I was able to find this about Conroe's implementation, which sounds fairly impressive:
http://www.sharkyextreme.com/hardware/cpu/article.php/3620036
The Conroe core includes support for Intel SpeedStep technology, and in an attempt to lower power and heat requirements, it emulates a mobile processor by lowering the multiplier when idle or in low usage. In the case of the Core 2 Extreme and Duo processors we reviewed, that amounted to a 1.6 GHz clock speed at idle. The Conroe can immediately fire up at full speed and match the system load. Core voltages can also be lowered through similar techniques, such as Intelligent Power Capability, which can turn computing functions on and off when needed, in order to fully maximize power efficiency.

Well the Quad is still the fastest when it comes to CS2. But man, once those are intel native that thing is going to fly at lightspeed.

I stopped by the Apple store tonight to play with a Macpro. I'm getting ready to buy and thought I'd get some hands on experience to see how it performed with Finalcut Pro. I was especially interested in how it handles playback of uncompressed footage.
The store had a 2.6 hooked up to a 30"ACD. Everything on the machine was stock. I launched FCP and it appeared with a project already loaded (about 5 seconds). The project was a simple 20-30 second 720x480 NTSC clip of hockey game footage. I selected the clip and copied it to a new layer and threw a blend mode on it AND changed the speed to 85%. Next I copied and made another layer and changed the speed and offset it and changed the transparency to 80%. 3 layers total with the top two manipulated. I hit the render and it finished in about 30 seconds. :)
I know, not very scientific, but I just wanted to get a feel for how fast the Macpro would render manipulated footage. Anyhow, next I changed the output in project settings to "uncompressed" and hit render again. Again, it took less than a minute to render and the CPU usage in console was maxing out at only 42% per core.
Once the render completed, I hit the play button to see how the stock Macpro would handle playback of the uncompressed footage. It played for about 4 seconds then threw an error saying that frames were being dropped during playback. Not good. I was hoping that the Macpro would be able to play uncompressed footage from the timeline without 3rd party acceleration or setting up a raid. The error message suggested turning off RT effects (of which I did, but still had dropped frames) or get a faster drive. There was a couple other things the error suggested, but I can't remember at the moment. I wonder if having the ATI card would have made a difference? Not sure if FCP uses the GPU for playback, but I would think that should make a difference. Ram would probably help too. Anyone know what might be going on? Am I expecting too much out of this machine?
Sorry for sort of getting off topic. I thought this might be an appropriate area to post this; I wasn't feeling up to starting a new thread.That's great info. Would you please tell us:
1. How fast that is compared to what Mac model-speed you are currently using?
2. IE Were you impressed or not so impressed with how fast-slow it rendered?
3. What kind of speed were you expecting?
I'm no expert, but my guess is that the lack of RAM may have been the culprit. Need more independent tests like this from other FCP users. Thanks a lot. :)

Where's the extremism?
obamacare in its smallest form is extreme
stimulus bill is extreme (and extrememly $$)
The extreme people he hires, etc.
Don't lose faith in his craziness just because he's postponed driving our country into the ground.
And it's a good thing he showed his birth certificate. How embarrassing would it be for us to look back, and the man who did all the damage wasn't even born here?
If you want america to be like europe. Go to europe and pretend you're in america. Don't jack up America for those of us who love it for what it was founded on.

On the server side.
The server/desktop division with Windows - as with OS X - is one of marketing, not software. Windows "Workstation" and Windows "Server" use the same codebase.
Couldn't be farther from the truth. I have no problem with Microsoft or Windows, evident by the fact that I've ran their operating systems for the last 10 years. I have a problem with all the crap they're putting in Vista, but otherwise - Win2k and XP Pro have left me primarily trouble-free.
Well, if you can't find evidence of Windows running on well on machine with >2 processors, or of the significant low-level changes Microsoft have made to ensure it does, you aren't looking very hard.
Similarly, if you're one of the "Vista is just XP with a fancy skin" crowd, you've obviously not done much research. The changes in Vista are on par with the scale of changes Apple made to NeXT to get OS X.

Apps already capable of saturating 4 cores need more cores to run simultaneously without compromising speed.That is what has already happened. You were unaware of that fact. So yes, it is a whole different ballgame already. :eek:
http://images.anandtech.com/graphs/mac%20pro_081406100848/12798.png
I think this speaks for itself.
When I'm working on one project, that's all my attention to it. When I'd like to encode it, I'd like my however many cores to be at full blast. Sadly, that's not happening at the moment and will remain so until they rewrite h264 encoding.
Like I said, unless people are doing what you do (sending multiple files to be encoded at the same time all the time) they won't benefit from 4, 8, 100 cores.
Now if anyone can show benchmarks that show FCP being 40-50% faster on a quad than on a dual when working on a project, I'll shut up :)

hey, i got it.
lets say you have a folder on the dock, and you open it, it opens in the dok itself. and you can scroll left and right to pass through like iphoto speed. and you can have more then one dock and they would like stack on top/side of each other to have several "folder" open, and you do a shortcut and your dock goes normal. i know my idea sounds like a mess but i'm sure apple can polish it up
Cause you can only have so many folder icons in a folder window so i'm sure that it would be about the same.
As for the new features, I love them and can't wait to use it, but it is easy to see where Apple gets its inspiration from
Time Machine- Just an easy and fancy backup program
iChat Share Screen- Its like a VNC connection. I do it all the time between my linux desktop and ibook all the time. If you can have both screens at the same time and drag files in between to download would be awesome
Tabbed Chat Windows- Open source has been all over this for a while
Spaces- Virtual Desktops. Probably inspired by linux, and perfected
I mean its great updates and improvements, but I'm still waiting for innovation. Like expose. I want a feature to improve the use of my computer, not just awesome features

I had a strange experience at Best Buy. About two days before the iPad 2 came out I went to my local Best Buy to ask about availability on release day. The employee I spoke to told me essentially that I should wait. He told me the iPad 3 was coming this fall and I should either skip the iPad 2 or purchase something like the Zoom. I pressed him how could he possible know that, I said I read all the rumor mills and such and time and time again no one actually ever knows that information. He said "they all did" (best Buy employees) it was posted on there "E-Learnings" site which is basically an internal Best Buy training/notification/product information system.
So here is an employee telling me not to purchase an iPad 2 because he thought the Zoom was better AND I should just wait because iPad 3 was coming out this fall.
WTF?
Fandroid.

Isn't this hypocritical since Apple has been known to do this in their retail stores too?
Apple has been holding their stock to the next day and opening early if they have any. I think thats a pretty good way to do it rather than having people check in every half hour with a "You get any yet?" This way its simple.
Perhaps BB did something completely different? Kept them for days or weeks. Who knows?!
Believe me Apple WANTS Best Buy to sell iPads. The more places the better. So they must have done something pretty stupid to have pissed off Apple enough to pull their stock.
I say good job Apple!! Beisdes I freakin hate BB.

Well, yeah, it will probably make more people happy, but it will be fun to see all the people bitching and moaning around here.
If I think the new FCP sucks I'll be b*tching and moaning too. ;)
Okay, okay, so they have done NAB (they've never done AES, though, that I'm certain). But still: They pulled out of everything in the last couple years. Why come back to NAB? Why not just do a small-scale announcement outside of NAB's timeframe so as to maximize press?
Apple was at the SuperMeet last year but it was totally forgettable. Adobe and Avid blew them out of the water. Why not do it at NAB when the entire industry is focused on what's happening there? All the industry press is at NAB and a ton of your target demo, especially the people that can best 'evangelize' your product, is there as well.
Was the supermeet focused on something else at one point? Because otherwise that sounds a little hard to believe that a usergroup would exist for a product that wasn't out yet...
Not to mention it's the 10th anniversary of the Supermeet and FCP debuted in '99.

Went down to Radio Shack today. They are doing a trade in but you're never gonna get the max price they offer unless it's out of the box new. My 3gs has normal wear over the year so they will only give 230 for it.
And I have a feeling trading in prices will drop when the iPhone 4 drops.

It is time for this silly issue to be done with. If you don't like his policies then fine... argue against those, but attempting to try and keep this birth certificate issue going on and on even after it has been released is not going to get you anywhere.
It was released... what else do you want?

No it doesn't, not when people brag about how much they sleep aroundThat is their problem, not yours.
Your link supports the idea that Greek society supported pederasty. If they have such a failing what is to say they don't have other failingsYou could say the same about the Catholic church. My link was specifically in reply to being asked for evidence - actually proof - that Plato was a homosexual. As for supporting bad stuff, the US Constitution was once quite content to support slavery and the subordination of women, and so were many of the founding fathers, both of the early church and the USA.
rape and paedophilia both involve lack of consent. Although paedophilia has to do with that the mind is attracted to pre-pubescent children in the same way that homosexuality causes attraction to the same sex. Both cases are untreatable.What absolute bollocks! Homosexuality does not need treatment, since it is not a disease.

Yes, absolutely:
Enhanced 64-bit Support
Leopard delivers 64-bit power in one, universal OS. Now Cocoa and Carbon application frameworks, as well as graphics, scripting, and the rest of the system are all 64-bit. Leopard delivers 64-bit power to both Intel- and PowerPC-based Macs, so you don�t have to install separate applications for different machines. There�s only one version of Mac OS X, so you don�t need to maintain separate operating systems for different uses.
Bridge the Generation Gap
Now that the entire operating system is 64-bit, you can take full advantage of the Xeon chip in Mac Pro and Xserve. You get more processing power at up to 3.0GHz, without limiting your programs to command-line applications, servers, and computation engines. From G3 to Xeon, from MacBook to Xserve, there is just one Leopard.
Wait. Does this mean that the Leopard doesn't support current MBP or MB? the ones that use 32 bit Yonah based Core Duo CPU.
