Do you have a reference showing that this translates to better performance in real-world application tests in a head to head competition?
Not handy, since a lot of this happened on mailing lists.
The short version is that the memory performance scales in a very sub-linear fashion as a function of the number of cores being used, whereas Opteron scalability is almost linear up to a large number of cores. The good news is that for single dual-core processors the memory performance is on par with dual-core Opterons and their in-cache performance can be better. The bad news is that this performance does not hold as you scale cores in a system. So for some applications (e.g. those that live mostly in cache) the Woodcrest processors will be mildly faster than Opterons, but for most the performance is about even in real app benchmarks.
I've seen fairly comprehensive benchmarks for both databases and scientific computing applications, both of which thoroughly exercise the memory subsystem. Even though a single Intel core theoretically has more bandwidth, the high latency means that the real bandwidth is about the same as the slower Opterons (which have real bandwidth that approaches theoretical) and the cross-sectional bandwidth of Opterons when you get up to 4 cores and higher is much higher since the scaling is almost linear with the number of cores. For Intel, I think it was the case that a bigger cache was a cheaper design choice than a truly scalable memory subsystem. As a result, they will have different competencies. Some types of floating point codes should run very well on Intel.

BestBuy are some of the most notorious criminals in this country and Apple should pull out completely from their worthless trash retail stores.
How are they criminals?
Are they as notorious as Al Capone yet?

I think that these tests are poor regardless of the results. Testing is all based on evidence and I see none, just what they say are the results.
When you run a test you normally document the process for the test conditions. You don't just say Photoshop CS2 - MP aware actions, but which ones - why didn't they use the Photoshop test.
"For FCP 5, we rendered a 20 second HD clip we had imported and dropped into a sequence."
Does this mean they imported a 20 second clip into a sequence and had to render the clip before it would play with the rest of the sequence.
They basically used the render tools in the sequence menu. Why measure something like that.

Apple support for me has been nothing but great. This year my household has bought an intel iMac and a macbook. Being revision A I was expecting some sort of problems with them at some point and the problems did come. First I had some serious video problems on the iMac. So, I made an appt using Concierge and it was right on time. So, the genius looked at the problem and in ten mintues told me I needed to have the logic board replaced. So, I left it at the store and picked it up 2 days later. I wasn't glad that I had problems with the mac but their support was great.
Now the macbook was having the dreaded problem of turning off at random times. This one was a bit more tricky. I made my appt just as I did for the iMac and saw the genius. She had to replicate the problem of it turning off at random before she could put it into their system in order to be fixed. Thankfully it turned off within a couple of minutes so she put in the request to have the logic board replaced. However, it took 4 days this time to get it fixed. While I would have loved to have had it fixed in the same time it took to fix the iMac I realized that just wasn't in the cards. It has been fine ever since. Although, a few weeks later the battery started to buldge but they replaced it right away and we were only at the genius bar for around 15 minutes to get a new battery.
After hearing the horror story of my best friend trying to get his Dell fixed I was certainly happy about my experience with Apple. (as far as the dell story goes he still doesn't have it replaced because Dell lost his notebook after he sent it back to them and they are trying to tell him that it was somehow his fault) The people at the genius bar were excellent with good customer service skills. While I realize that some have had experiences that weren't quite as good I thought I would point out that some of our experiences with Apple support have been excellent.

This is RIDICULOUS! if you switch off location services your location is still being tracked by the mobile phone companies everytime your phone makes a connection with one of their masts, which happens everytime you move cell. Oh and this happens with every phone, otherwise they wouldn't work.

well, if you are going to tell people their posts make them look stupid, perhaps you should consider your own, and read a dictionary before throwing around three syllable words. Your use of the word "eloquent" is incorrect. "eloquent" is not a word that applies to a software operating system.
Eloquent: The quality of artistry and persuasiveness in speech or writing; the practice or art of using language with fluency and aptness; fluent, forcible, elegant or persuasive speaking in public.
As in; "your post was not eloquent".

It makes total sense to hold back the units for the following reason:
Day 1: Someone calls up BestBuy to find out if they have the iPad2. They reply, "yes we have a very small amount in stock". Customer arrives at the store and they are all sold out but they are told that there will be a few more on sale tomorrow. Customer picks up some random crap like a DVD, mouse or whatever.
Day 2: Customer arrives at the store and they are all sold out but they are told that there will be a few more on sale tomorrow. Customer maybe picks up some other random crap and leaves.
Day 3: [Same as Day 2]
Day 4: [Same as Day 3] etc...
If you just release a few each day, customers will keep coming back in hope of finding one and possibly buy some other small items while in the store. If you sell them all out and have nothing for weeks, you will have no customers coming to the store. BB knows that the iPad2 is in short supply and that they will have no trouble shifting the stock if they need to so they are happy to sit on it and keep a steady flow of customers coming through the store.

Just think of it like this, how hard would it be to fraud this? NObama's administration could whip one up in an hour the most.
While I personally don't doubt NObama is born in Hawaii, I doubt this will matter for one bit.
Who is NOBama? I looked up that name on Wikipedia but haven't found anything.

This is good news for me.. it will make it easy to resist buying one this year. No 3ghz xeon, no bluray, no new case design.I agree as I am waiting for the 8 core model with Leopard while I continue to limp along on the Quad G5. ;) I run an external Optical on top of my Quad G5 so this would be a nice addition. But I also run an ATA/133 HD inside on top of my optical on it's spare bus port, so it's really not much of an improvement from an internal HD perspective.
What's great is the idea of Apple holding the prices the same in the middle and top while lowering the bottom model's price. Lowers the barrier to entry in this class of machine. But I do think this series is a good transitional setup for those who can't wait for Leopard and have been waiting for Intel longer than those of us with the last of the G5s - especially those coming from G4 Power Macs that are way long in the tooth.

I bet you that you'll never see a iPad with screen resolution like 2048x1536, it's a ****ing nightmare to iOS developers. You don't understand that it's ****ing crazy, iOS interface like MacOS X interface is not scalable. Apple have to change the whole GUI before making this step forward.
what did Apple do with the iP4? Oh wait...
As far as Devs are concerned, they 2x the res for their ease. Sorry, its not that "****ing crazy". Oh, and before someone says "well theres not going to be a mobile GPU that could handle that res"; not true, even now theres some great emerging technologies that have handled concurrent instances of 1080p (like 10 displays)...much less whats going to be available in 2012(if we survive the world ending:) Furthermore, native apps like iBooks/iTunes/etc dont require heavy processing to display hi res. Sorry man, youre wrong.

Not everywhere is the apple support poor. Here in the netherlands I can't complain about the service and support!
I think it is also because of the knowlegde of apple. They have worked years with the "old" powermacs, and they know how to repair or support every problem and/or hardware, just because there expirience..
Now apple is switching to Intel, They don't have that expirience that they had with the "old" powermacs...

For a programmer dealing with Terminal, Xcode, Netbeans, Eclipse, etc (not graphic intensive softwares), would this macbook air be a better deal than the 13/15" Macbook pro?
Anyone?
Sure if they allow you to bump up the memory to 4GB it should be more than usable especially with the SSD. May be you will need to hook up an external disk for storage needs but apart from that it'll all be good with the i5/7 lineup.

You're wrong. Apple is losing marketshare for over 2 years now. Just because they are selling MORE iPhones doesn't mean they are gaining marketshare. The market grows much faster than the iPhone sales. Have a look at Nokia: In Q4/10 Nokia sold almost 7 million more smartphones but they lost about 10% marketshare. In Q1/11 Apple lost about 2% marketshare despite the fact that they sold about 2.5 million more iPhones.

When they revamped Logic Pro they cut the price from $999 to $499.....fingers crossed for FCP.
I think you mean Final Cut Studio. Back when I first started editing it was $999 for Final Cut Pro, alone.

Thank you for your constructive reply but ....
to be fair, devs care about that... users won't until they see new things that they can use. then they/we can complain about backward compatibility!

"Is it your position that Libya represents a larger danger to American assets/security than Iraq? If not, is it your suggestion that America should be involved in every humanitarian crisis with brutal dictators worldwide, or at least those comparable to Libya? If so, why aren't we in North Korea? Why aren't we in any number of African nations?
I think this is a fair point, and it really doesn't matter if it's the United States making the calls, or the United Nations. We are essentially playing "God" with the other nations of the world. My complaint on the first page revolved around the lack of a quantifiable threshold for intervention. We inadvertently play favorites, and the world has every right to wonder about the motivation any time the USA takes action against a sovereign state. We should either stay out of ALL interference, or else put on the damn star-spangled cape and superhero tights and get to business already. Wherever evil is, we must go and fight it! :rolleyes:
Why you keep on referring to Iraq when the scale of action in scope of resources and time isn't remotely on the size of the Iraq invasion, is a complete mystery. If you're attempting to make this Obama's 'Iraq' folly, then you will fail. This will be off the front pages of US papers in terms of US engagement within a week or two.
Quite right. So far the whole Libya affair has a lot more in common with Desert Fox (http://en.wikipedia.org/wiki/Bombing_of_Iraq_(December_1998)) than Iraq...

Thanks ksz. I checked it out and the multi burning capability is great. But Dragon Burn will not let you write Images which I find incredibly lame. I use Toast 7 a lot and I use it most of the time to write images not to physically burn discs. I would love to be able to write multiple Images with something. But, alas, Dragon Burn is not it. :(http://www.creativemac.com/2001/04_apr/news/toast53.htm
Still, from what I've read you need multiple instances of Toast open. I'll try Disk Utility for burning two images at once when I get a new image that I need to burn.
