No I think you are confused. :) I meant "Is having more cores, lets say 8, more efficient than one big core equal in processing power to the 8 cores?"
First of all, you assume that it is possible to make "one big core equal in processing power to the 8 cores". I don't think it is possible to do this (at least not with the x86 architecture using today's technology.)
But assuming such a chip exists, the answer depends on what kind of efficiency you're thinking of.
If you mean computational efficiency (meaning the most useful processing per clock-tick), then a single big core will do better. This is because single-threaded apps will be able to use the full power (whereas multiple threads are needed to take advantagte of multiple cores.) Also, the operating system can get rid of the overhead that is needed to keep software running on the multiple cores from stepping on each other.
If you mean energy efficiency (amount of processing per watt of electricity consumed), then it could go either way, depending on how the chips are made. But given today's manufacturing processes and the non-linear power curve that we see as clock speeds are increased, the multiple-core solution will almost definitely use less power.

The Meh was strong in that keynote. I was looking for something explosive and found a snap bang that someone threw to the ground. Short of those top secret features :rolleyes: being something earth shattering Leopard looks to be another micro update to OS X. While any forward momentum in the OS is a good thing what we've seen of Leopard does not suggest that gulf that will be closed with Vista (After SP1 & 2 that is.) is going to be widened again with Leopard.
The things dumped into the OS are simply more addon crap. That isn't to say adding new features aren't welcome but the time is right for a serious revamp to the UI of OS X.
I'm not happy about this development. It seems as if real forward momentum in OS X has all but stalled. Like most of Apple now a days they aren't taking chances anymore with their wares be it software or hardware. They seem to focus on finding previously used ideas, slap a new coat of paint on it, buff it up to a nice shine, then give it some "fun" name and call it innovation.
Apple may have been in decline in the 90's but at least that Apple took chances. Took risks on new and innovative hardware. I want the old Apple back. . . to a point. More then anything I want to get excited in a product that is revolutionary not evolutionary. :(
Call me a cynic, but I'd say Apple either hasn't implemented them yet or hasn't thought of them yet.
Or they are so buggy at this point they aren't ready to demo them. That is my guess. This crap about not wanting MS to copy. Sorry but Windows is feature locked at this point. There is simply NO way for Microsoft to roll out anything new unless its such a minor thing that it would be easy to do. I really wish Apple wouldn't spit in my face and call it rain.

While there are some racists who tried to jump on the birther bandwagon, I did see plenty of non-racists have some concern about where Obama was born, or if in Hawaii, being born there before it was a state and then being a coverup to put his age right after statehood.If those people really were non-racists, they would have ignored such questions entirely, confident in the knowledge that if anything untoward was going on, the World's Greatest Intelligence Agency� would have found it out before he even got his name on the ballot.

I already have those stats, I want to see them drop in a high-end Conroe (~3GHz) so I would know that I could feasibly upgrade my 2GHz Core Duo in the future. It's possible, isn't it? I mean, the G5's were really hot, and the iMac enclosure could handle that, wouldn't the new Intel ones be able to handle the Conroe Extremes?I think you might be able to put a Merom 2.33GHz in there without much trouble. But I dont' think Conroe is pin compatable with your iMac. :)

Hmm we have a Blu Ray burner in our duplication bay in 3 years and approx 1500 hrs of Broadcast HD TV it has only been used so editors can take home personal projects to screen them.
Really do not see the need for Blu Ray at all there are so many other better suited formats.
It all depends on what you do for a living I suppose. I can see wedding video makers would want to deliver blu-ray.
I don�t do weddings, but I would at least like to have the option to easily make a Blu-Ray longer than 20min . Now every time we give people a HD format of what we have done, we usually end up with an Apple TV HD file and that�s a very compressed HD file IMHO.

The principle of any and every cell phone is that if can connect to a cellular network signal, it knows where you are. Based upon every unique cellular ID, the networks know how to route incoming calls and texts to you, If it didn't how that. how the h#!! do you think you'd get any calls? Right now, sitting at my desk, Verizon knows exactly where I am (based upon triangulation of the nearest cell towers. They have my unique cell ID and my account information. My dumb phone even has a gps 911 locator on it. I dial 911, they know where I am.
Side story: the credit card companies know exactly where I am better then the cell companies. Every time I swipe my credit or debit card, they know where I am. When I travel for vacation, I am very likely to get a call from my credit card company (on my cell) asking where, when and how long I will be traveling. They know every store and every purchase I've ever made on a credit card.

Many Best Buys with Apple Shoppes have Apple representatives who work right at the store, I doubt they would let this happen at their store. I wonder how many Best Buys have done this
The Best Buy I bought my MBP at was in an Apple Shop and had a great representitive in it. Dan was great and could not have been more helpful. I hope the first time I visit a Apple store I have a similar experience.

hi,
i've just sold my dual g5 because
i plan to buy a new macpro in august.
But seems that it will be already obsolate after 3 months.
Please can you tell me if the socket of woodcrest
will make the macpro upgradable one day,
or these new type of processors need differet socket?
Thanks.

I have just ordered a mbp :( It wasn't supposed to ship until Monday but it shipped early :( If the rumors are true will I be able to send it back and get the new one? Has anyone had any experience in returning unwanted stuff to apple as time is not on my side (leave for uni on the 16th Sept)
The only change is likely to be the cpu. The rest of the MBP will probably be kept the same and if you look at the yonah vs merom benchmarks at places like AnandTech, it probably isn't worth sending it back.

Also, 1GB of RAM, who are they kidding? More like Mac Amateur
Many prefer to buy their own RAM because it's usually cheaper. There would be more people crying if Apple bundled 2GB of expensive RAM. They could offer a RAM downgrade of course, but then why not just give the price of the downgraded version, which leaves us at square one again.

It has been rumored that there might some minor changes to the computer such as easilly removable HD, differnt latch, as said above. But more importantly, I hope they bump the clock speeds and include 1GB RAM as standard on lowest MBP model for the same price.

Why would Apple show their Clovertown workstations after HP and not simultaneusly with HP?
Because HP is a much bigger company with much bigger sales volume and probably gets all the new processors before Apple does.

bibbz,
Phew!
You are doing all of us a great service here with this information.
The salesman just called me from the store I was in today.
He is telling me that there is no guarantee of the iPhone even
if you get the pin -- but he admitted he was not certain. All he
knew was that there was something like 9500 pins nationwide.
Told him that I had just read your message and that you were
saying if I got a PIN I have a guarantee of a phone.
He warned me that Radio Shack does not want the word
"guarantee" used.
I am putting a lot of faith in what you are saying here.
I will be at my Radio Shack store early tomorrow.

As a consumer, why should I be subjected to this risk which doesn't benefit me in the slightest? And why should this data be "backed up," secretly, to my computer?
The Wall Street Journal has found, however, that this newly-publicized database is constructed even when location services are turned off entirely.
From the front page of macrumors, for all those who've said to turn off location services.
This IS the type of thing that should be ruled on before a real problem develops.

Sure, but did Samsung patent it?
It's not about 'who copied who?', but 'who copied after who patented?'
All the corporations mentioned in this thread are dinosaurs and know what type of business they are in. If they fail to patent their (good) ideas than it's a given that someone else eventually will. Doesn't matter whether we or anyone thinks that's right or wrong. It's normal business practice. Any corporation thet develops products in a hot contested market like this and doesn't play this game will lose business or cash.
Samsung didn't stole it from Apple since they were first with the design, end of story.
Samsung can claim Apple stole their design and patent it. That's fraud right since it's not their own idea?

As an example; lets say the local BB store got a 100 iPad 2 64GB 3G's in this morning. That is about $830K in sales. And lets say they average sales without the iPad 2 for the same day LY was $500K. Next year that manager would be looking at needing a $1.3M+ to make his goal.
Good example, bad math. 100 iPad 2 64GB 3G = $830 x 100 = $83,000, not $830K. If Best Buy stores were pulling in $1M+ per day or even $500k+ per day then their stock would go through the roof.
I concur with you on the whole bean counter thing. I work for a large company and its amazing to me how much money bean counters waste in their attempts to save a few pennies. We once spent over $10,000 in time (when computing hourly wage by salary) to purchase a $100 piece of software because the bean counters tried to make us jump through hoops to prove we really really could not do without it. It was sad.

Sure, different people have different experiences. That's partly why some people feel same-sex attractions and why others feel opposite-sex attractions. Macaroony doesn't see any point in opposite-sex attractions. I don't see any point in same-sex attractions.
And yet I doubt Macaroony sees opposite-sex attractions as immoral or placing oneself in grave danger. I know what your religious beliefs tell you, and it is your right to follow those as explicitly as you are legally able. But why does that have to impact the rest of the world when you know many of them share different beliefs and have different experiences?
Personally, I think people who believe in gods are weak-minded fools. But I would never support a law that mandated atheism or banned religious gatherings. Because these religious things, while they are not in line with my worldview, do not impact my way of life directly, and allow people to live how they think they need to, not how I think they need to.
Invalid because it endorses something that could cause the collapse of society
I'm gonna go out on a limb here and venture a guess that you don't have a non-biased fact source for a retarded statement like that. :rolleyes:

NOT TRUE....The Quad core G5 people are in an uproar because Logic Pro only uses 2 cores on the G5....they updated Logic Pro so it uses 4 cores, but the G5 Quad still only uses 2 cores....there are also photoshop actions that are NOT multi core aware so will only run on one core.....Hopefully 10.5 will make all this irrelevant.
You totally missed my point. Even if an application uses only one thread at all times, that application is still a separate process from all of the other processes you have running. At any given time you'll have at least 30 something processes, even when no user-land applications are running. OS X will spread out those processes to try to utilize all the cores as much as possible.
In reality, there are probably not too many non-Apple applications which routinely use 8 threads or more. In the near future I expect all applications to use at least 2-3 threads, even the most simple ones.

So since these new mobile chips are pin-compatible with the Yonah chips (like the one in my MBP), will it be easy/possible to simply buy one and upgrade myself?
With things like this, my rule is: If you have to ask, then you can't do it :-(
At the very least, you have to open your MacBook, get access to the processor, remove it, put in a new ones. But laptops are not built to be opened, and the processor is most definitely not intented to be swapped, so you might have to take an awful lot of things apart. Now taking it apart is the easy part, putting all the things back together again with everything fitting and nothing left over, that is the more difficult part.
It is one thing to try these things with a cheap MacMini, especially if your goal is not to have a faster MacMini, but an impressive webpage. Risking a $2000 MacBook Pro is quite another thing. Better to sell your MacBook/MacBook Pro on eBay and buy a new one.

The problem with a lot of reviews is that they wanted to publish theirs before everyone else instead of actually playing the game first and knowing what they are talking about.
As far as damage goes, you'd be broke at the end of the first series if they made you pay for repairs right away. This is why they dsq you for hitting opponents or running off track in the license tests and spec events.
