Is having more cores more energy efficient than having one big fat ass 24Ghz processor? Maybe thats a factor in the increasing core count.
Actually, this is well documented.
There are serious electrical and physical problems with jacking up clock speeds much further than they are now. Intel managed to push their chips to 3.4GHz, but the power consumed was tremendous.
When you can't ramp up the clock speed, your next best alternative is to go for as much parallelism as you can - increase the number of instructions you can execute in a single clock.
Chip makers achieve this in a wide variety of ways, including multiple CPU packages on a motherboard, multiple cores per CPU package, multiple threads per core, and multiple functional units per thread.
And yes, a single CPU at 3GHz can easily consume more power than two CPUs (or two cores) at 1.5GHz.
As for your theoretical 24GHz processor, such a thing is simply not possible with today's technology. (Well, there were some university experiments that hit insanely fast speeds, but don't expect commercial products any time soon.) Given the heat/power curves of today's chips, I wouldn't want to think about the cooling requirements of a 24GHz chip if you could somehow manage to build one.
Of course, breakthroughs do happen, and higher clock speeds might become practical in the future. But multi-core tech isn't going away - we'll simply end up with multiple cores at higher clock speeds.

Okay.. well I guess I wont be taking my chances at RadioShack. If they let me preorder, would I be good to go on launch day? Or could i still encounter problemsLooks like it will be no problem to lock in an iP4 for launch morning as long as we pre-order next Tuesday morning. It's sort of like 2 launch days - pre order next Tuesday the 15th for a $50 advance (in the form of a gift card) and receive the 24th. The Shack is much handier than any other launch store for me. :)

I'm pretty sure you are aware that Apple would use LV CPU in 13", not ULV. That bumps us to 2.3GHz plus Turbo. You have said this yourself too and I already covered the reason in my other post.
This is just a MR article and surprisingly, they don't have much idea about the TDPs. Hopefully they will correct their article so people won't live in confusion.
That isn't what this story reads, and I don't think anyone but you and I have even read the actual facts supposed here.
I actually find this one of the least accurate stories ever posted on MacRumors.com for several reasons... the OP is assuming ULV in the 13" MBA. The OP is assuming that if SB IGP is good enough for MBP it's fine for MBA. There is no rumor or timeframe listing these chips especially not in the 13" MBA. It seems like it's a blatant attempt to stir up activity without any real facts, rumors, or even common knowledge about the chips used in the MBAs.
Certainly the people haven't read the story or they're somehow focusing on the 11" MBA. Sure, this would be fine for the 11" MBA in terms of CPU clock speed but even then it's a gigantic loss in the graphics capabilities. That leads to a problem with the author saying good enough for 13" MBP than good enough for MBA. However, the IGP clock speed used in this ULV chip will be nearly a 50% drop in graphics performance. That for me doesn't equate to if this then that...
I am disappointed with MR for even writing such a poor piece of garbage. Forget that I cannot stand the SB IGP... the assumptions made here are absurd! It
definitely doesn't warrant this sort of reply from the fans of the MBA. You and I
could assume things all day, but that isn't the story written.

Alright, I was originally going to take Apple's side on this, since I could clearly see it looks a lot like iOS, but having looked at Samsung's F700, I don' think Apple has any right to sue..
Although the Samsung F700 has very simple icons, Apple clearly has the same placement of icons, even looking at the bottom you find the four dock like icons..
http://img263.imageshack.us/img263/9559/samsungf700cellular.jpg
I'd say that Apple copied Samsung :P.. Honestly I'm not one to take sides just because I like Apple Products, I just think its wrong to sue since Samsung clearly had this type of UI first.. Apple has no right to sue..
Which launched 6 months after the original iPhone...and was displayed in February of 2007 with an entirely different interface.

It's because of the Buy One Get One option. Nothing more. People choose that option because it makes financial sense and if they don't really care about the OS or the phone, they will choose the one that fits their check books. If Apple was to OK ATT and VZ to do a Buy One Get One on the iPhone, there would be no comparison. It would be game over for Android.

I ordered my 15" MBP yesterday and they are telling me it will ship next Tuesday. I sure hope that when the package arrives the MBP will have no stinking Merom, no more than 512 MB RAM, no better than an 80 Gb/5400 rpm HDD, and -- please God -- no magnetic latch! Oh - and one more thing: Apple better not send me a refund if they lower the price before the package hits my doorstep. :mad:
I don't think you've got anything to worry about there...

They already get 79 cents out of every 99-cent song sold, and they don't have to pay a penny to produce or distribute the music, as they would with CDs. Apple has given them a more efficient way to distribute music, and they come begging for a share of iPod profits. Ridiculous.

As bad as it sounds for Apple to "boot out the others", Apple doesn't have the authority to do that. FCUG organizers chose to do it at Apple's request because they require the space and time. FCUG could have said no to Apple, but why would they? It's not a Canon Group, it's a FCU Group...

I have to say that I think a lot of people have missed the point around various software not using all the cores. There is a simple reason. Developing multi threaded apps is hard. And until recently (~1 yr since G5 Quad) developing for more than 2 simultaneous threads (cores or processors) was pretty pointless on a Mac and completely pointless on a PC. Why would a developer bother to develop for more than two thread unless they expect threads to get blocked easily or there to be more than two cores? That's why browsers are one of the few genuine multithreaded apps, rather than 2-4 threads, the threads block easily, so having multiple makes sense. In a lot of cases where there was the opportunity for parallelism using a vector processing unit often makes more sense than multiple threads. Why spend development and testing effort on a solution with no hardware to even test it on, let alone deliver and make use of?
The whole industry is taking a 90 degree turn and the tools for developing multithreaded applications are not up to scratch. Look at some of the commentary about XBox 360 and PS3 development.
The dev tools will come, the software will catch up with the hardware, in the meantime just be glad that you can play your stolen MP3's and browse your pr0n without interfering with each other and stop whinging.

Personally, I highly doubt we'll see ANY iPod/iTunes updates here... WWDC is historically a developer/pro event and not a consumer event.
Well, if the rumors of the "full-screen, touch-screen iPod" are true, maybe Apple will open it to developers and introduce a "make your own apps and games for the iPod" dev. kit, which would make sense at a WWDC.

...the GSM providers' coverage area is inadequate. I need a phone that works most everywhere (in the US), not just along expressways and in major cities. Bad as it is, CDMA is the only practical option for those of us who travel.

This is Trump's MO. And it's working! Even if you don't like Obama's politics, you have to admit that Obama has much more class than Trump.

It's always a little alarming when a post starts "sorry if I missed it but..."
The 2.7 G5 will be the highest clocked chip in a mac for a while, but probably not the fastest. In a number of benchmarks, Yonah has already beaten dual G5's, the conroes and woodrests will likely widen the gap even more.
true.... didnt the Macbook outrun a G5 in final cut studio or something?

Sheesh...just when I'm already high up enough on Apple for innovating, they throw even more leaps and bounds in there to put themselves even further ahead. I can't wait 'til my broke @$$ can finally get the money to buy a Mac and chuck all my Windows machines out the door.
How is this Apple "innovating"? Anandtech just put pre-release quad-core Intel-processor in to an Apple-computer. Apple itself had nothing to do with it. They could have used quad-core Dell-machine just as well.

alot of itunes people don't. we are the people actually paying for it. so screw that.

Not quite, W7 is still based on Win NT technology, dating back to 1993.
OS X is still based on UNIX, dating back to '69.
ZING!
Thank you....
The only time I would be excited, literally, about a MAJOR release is if they went to an OS which was slated to be described by Canines.
"Canine" would mean that it smells bad (especially when wet), and is without pride, and is basically dumb but can learn tricks for kibbles.
Yes, bring on OSX "Poodle".

Apple is now getting their parts from the same bin that PC makers use. Intel = cheap parts. Cheap parts = low quality.
Same thing with the batteries....
OS X can run on PPC and X86. Apple should target X86 to consumers and PPC for pro's.
That $100 million that Apple just wasted on Creative could have meant new supercooled mobile G5's if it would have been pumped into IBM (Power.org). Instead we have these halfbaked Wintel parts to deal with MUCH fewer problems with PowerPC based Mac's.

http://www.appledefects.com/wiki/index.php?title=MacBook_Pro
If Apple could not get IBM to provide cooler and more powerful chips back then with the full set of customers behind them......... what makes you think that the pro comunity will be able to do so?
I have no idea what the pro vs the rest of us is but I am sure it is less than 100% of all users, as such it is less likely.
IBM has no incentive to produce a cool and fast chip, our pro comunity also wants performance to create all those videos and edit all those photos.
There are a few snags, but they will iron them out. I am glad they did the switch to Intel. Do notice from my signature I do not yet own one, I am waiting for Leopard to take full advantage of the Intel chips. So this time next year I will be looking to get my 1 or 2 additional systems based on SantaRosa and Leopard.

eh, I don't see how it's significant for anything other than aesthetic purposes. If you're working in the dark the display itself is going to provide enough illumination as it is. Just seems like a waste.
Well, I work on my MacBook Pro now in bed and it's a pleasure to type on the back light keyboard. You reduce brightness of the display when you work in the dark conditions, I do. So, it's not enough to see the keys, but I don't much care about it, because I could type without looking on the keys, but most of the Apple customers who buys Air's can't type blind.

While Apple may yet issue several such candidates before reaching the final version to be released to consumers, the candidate designation would suggest that Apple has essentially completed development on the new operating system version and will simply be fixing bugs that crop up at the last minute during the testing process.
so, it's beta #1? Feature complete but still has bugs to iron out.
Golden master is usually when they are confident of no bugs isn't it?
