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.

Another person who can never be satisfied.:rolleyes:
Are you telling me somebody who spent thousands of dollars on "premium" hardware doesn't have a right to be pissed when both systems he bought were DOA? That is stupid! Apple should have kissed his ass and gave him a new computer after the second major repair. He was nicer than I would have ever been. I would have gone to the Apple store and caused a HUGE scene in the middle of a busy Saturday about it.
Apple computers are expensive. They are worth it when they work (and they usually do) but when Apple makes a mistake they should correct it better than anybody.

Yeah, now all we have to do is be able to afford it. Wonder what the price point on tigerton or clovertown is going to be.
Yeah thats what i want to know. Because right now i have a dual-core powermac. I'm interested in this mac pro now, if i have huge upgradability options in the future, and also depending on price. I can wait til january, but if all that will happen by then is that there will be a 1K bto clovertown/kentsfield bto, I probably couldn't afford that anyway, and don't want to wait, but if they are going to upgrade everything, to the octo-core chip and prices are around the same, even if they increase, i would wait.

That's nothin'. I remember shortly after the new MacBook Air was released at BB I was playin' around with the demos and was listening to an older man with his teenage daughter talking to the salesman about getting one. Then I noticed they ONLY had the more expensive versions (bigger SSDs) on the price cards. The old guy was oblivious about the different versions and the daughter was spoiled so he agreed to buy her one. When the sales-twerp went into the back to find one I pulled up the inventory right there on the demo model and showed the guy the cheaper model. When the sales-kid came back out the old guy asked him if they had the cheaper model in stock. The kid played dumb and pretended he didn't even know there was such a thing. I helpfully pointed out the one on the inventory screen and its "In Stock" status.
Long story short: kid acts surprised and confused, goes gets one and old guy buys his daughter a $1350 (instead of $1650) computer to update her facebook status with and thanks me for not minding my own business ;)

feel free to point out how difficult it is to see any similarities...
I think 3M should sue apple because the Notes icon looks like a 3M notepad.

This preview of Leopard seemed really like a glaze over of some "fun" little advancements, it did not look polished at all...to all those dissapointed in what leopard has to offer, not to be punny, but steve has barely let the cat out of the bag

My bets are that it will be either with Nokia or with HTC.
Nokia make the best phone interfaces in the world, which is a very Apple-like thing to do. They're also very experienced at phone hardware desigh and integrating it smoothly with the interface.
HTC are a taiwan company that design and make the best phone hardware in the world, and then sell them to companies like O2, T-Mobile etc to put their brand on. Most HTC-built phones run Windows Mobile, which Apple may be interested in replaceing with OSX Mobile...
I can quite easily see Apple commisisoning HTC to make a Apple phone, these people are simply the best at hardware phone design and manufacture.
Someone suggested Blackberry, but Blackberry is more geared to corporate use - not a very Apple-like sector - and also are quite heavily dependent on having access to a Windows server to get the most out of your phone.
Overall, I feel it will be HTC and OSX Mobile...
I'll second the HTC vote. The Cingular 8125 (an HTC PDA phone) is an awesome design and a well-built phone. I'd love it if it wasn't Windows Mobile.

I don't know, I thought Spaces and Time Machine looked very polished, personally. Spaces in particular is one of those things that I actually think will be genuinely useful (like Expose before it), and I like that it seems to be an even more useful implementation of the virtual desktops concept than what I've seen in Linux.
I hope that Spaces will integrate nicely with the Mighty Mouse...somehow...

The difference between me and you is that I'd want an explanation in either account. ;)
Get Dr. Gilbert "Gil" Grissom, (Ph.D.), on the case.
I'm sure he could match the keystrokes to a late 50's/early 60's typewriter.

I can't wait for Monday. I'll be working that day, so I am going to try to watch the keynote before reading any updates. I even have the Quicktime Events page bookmarked. :D I figured I would be more surprised by taking this route.
This is the first WWDC I'm really looking forward to, mainly because of what we're going to see... Leopard in action! :D
Edit: Peace, that's not entirely true. None of us know whether Apple will release Cinema Displays with iSights built-in. I'd say it is unlikely, but you never know until it actually happens.

All of the reviews of the Core 2 Duo say that it crushes AMD in the desktop arena. This is good news, now we just need new iMacs, MacBook Pros, and Mac Pros.
Can't wait to hear Steve Jobs' spin on the Core 2 Duos at WWDC. He makes everything sound so good, and with the C2Ds really good, it should be fantastic! :)

IMHO i would love to see an 11.6 MBA with an i3. So that there could still be enough power for backlit.
And please, do make the screen better for the 11.6
There isn't an i3 in any low voltage or ultra low voltage spec for Sandy Bridge.

Well, it seems like you are the one having hard feelings...so chill out, since we all try to be polite in this forum...otherwise, just go visit some other place where you can vent your anger on people.
As I said above, I am talking about facts and statistics...I am sure there a few cases where guys are just unlucky and receive one lemon after another...but this does NOT represent a trend nor a relevant percentage. You must have this impression because you go to an Apple Support forum and see 100 posts complaining the hell out of it...you just fail, and fail badly, to realize that there are some 1,000,000 users out there with no problems at all.
Anyway, before you start babbling again, check the link below...these are FACTS, not whines.

So please, before you spit out some fire, bring me some real facts, like percentage of failures and so on...the report I've read above shows Apple as having the LOWEST repair rate and HIGHEST trust of all makers. This, for me, is relevant; not random screams in Mac forums.
Really no hard feelings. You are right, and the professionals who do test and write reports
are making their reports up... Statisics, as we all know can be made to look one way or the other. The fact, that APPLE is acknowledging quality issues just proves that they themselves are not happpy with what's going on since the intro of the new MB and MBPs.

Google's "openness" reminds me of the days when people got all excited about being able to use different fonts and font sizes... sure it is exciting to see the possibilities and to be able to "customize" your documents, etc., but in the end, you only end up using a hand full of them (despite thousands of them being available), and most of what is being used is STILL what was the default choices back then.
Just like a kid that thinks they're going to be greater and better than those older than them because they know better; well, surprise, surprise... Google has turned out to be worse than IBM or Microsoft or Apple ever was. The deal with them will just keep getting worse and worse until people come up with genuine alternatives to their constant lying and deceptiveness (oh, yes, picking up 10M wi-fi SSIDs was purely accidental...).
I don't blame them for having to switch gears on this... I blame them for not being able to see 5 mins in front of their face on this issue (like so many other things) and insisting that "they're" correct every time it is obvious to everyone outside their company that they're not...

So what apps will saturate all four cores or at least get close to it, on either a quad G5 or quad xeon? Are there any?
Are there any apps that really take advantage of four cores on their own?Toast 7.1 UB can use more than two cores. In my test at the Apple stopre last Saturday I saw Toast 7.1 UB use more than 3 - between 2.3 and 3.1 cores all the time on the Mac Pro. It also uses more than two on the Quad G5 - just barely. Handbrake is not yet optimized for Mac Pro and uses a little less than two on both. That use of two is negatively impacted as soon as you start doiong something else especially both Toast and Handbrake at once.
But in future it will use all four. The problem with that "test" you so highly value, is that the testers didn't have a Quad to compare to, so they didn't even search out applications that are already "Quad Core Ready" - that would make a nice bullet on a software package wouldn't it?
Better yet: "MultiCore Ready".
If you don't think you are going to ever use more than one thing at a time, then you are right. But I think most of us here have 10-15 things open at once and do all sorts of things at once. That's the reason for "Spaces" in Loepard.

I hope there's been a significant overhaul in Spotlight, beyond what Steve hinted at already. There was no video demo on the website, so hopefully that's the case. It was a really underdeveloped feature in Tiger.
