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.

does anyone see a potential for a security breach with the ichat feature that lets you take over someone's desktop? (the purpose is of course to collaborate or to help them fix a problem)
I think it's an invitation .. like "Come share my screen with me" not "Let me use your screen"
So basically you have to allow your screen to be shared with someone you don't trust ... which is generally a bad idea anyways.
If there's a problem, you can always unplug the computer.

I really hope that they keep the option for a matte screen open when the upgraded MacBook Pros finally arrive.
I have been waiting a while now to upgrade to a MacBook Pro but have held off primarily as i would like to see if the enclosure gets a few nips and tucks a la Macbook!
The switchable HD bay would be awesome, and the magnetic latch and updated keyboard also would be nice but PLEASE DO NOT make glossy screen a standard on Pro notebooks!
I have a few friends who own PC laptops with glossy screens and all of them have keyboards imprinted on their screens! I cannot say from experience if this happens with the MacBooks but i'd rather not risk it....

MacBegginer and MacBookBeginner: Enough of this "Pro" stuff, the MacBeginner will be an old beige Performas with a Duo core shoved in there, to help the recycling effort. The MacBookBeginner will be an old 1400c, as they had a few dozen still laying about.
MacCon: A cardboard box with both an Apple and "Intel Inside" logo on the front, a blank CD stuck in the side, and a hole in the top (simulated iSight for your friends). Will still be superior to anything Dell has.
iPod Newton: Radical case design redesign for the iPod where it will now survive a fall from an apple tree.
XBox Server: Microsoft and Apple join forces again. X-box controls included with every XServer, but because it's Microsoft, it locks up more frequently. Server reliability plummets, but the help desk techs have a LOT of fun.

I got a prize car for getting all golds in Beginner and Amateur categories. I dont remember what it was, but i recall that when i got my last gold in each bracket they gave me a car for completing the whole thing.
I've started rally a bit today while i save up for a car with a bit more balls. Rally is completely sublime. I am loving every second of it. I had no problem with the dirt and snow tracks, but the tarmac rally is giving me some trouble. I use an 06 Focus ST that is around 215hp, so i can bump up the HP and still compete in the series. I might just have to do that.

From now on, whatever processor Apple has, Windows has, and the differences will come down mostly on the OS.
I agree with your post and I'm also a PC-TO-MAC CONVERT. :)
The difference is going to come down to OS, as well as, the overall design of a machine and how well it's engineered. Apple seem to engineer machines of high quality, from the mere fact that their machines stand the test of time e.g. the other day I was working on a G4, on FCP 5.1, editing and rendering HDV footage in its native format, HDV1080i50 (Australian Sony camera). Although it wasn't the quickest performance, it held its own.
Also, I'm an I.T. guy transitioning to film (pre-prod, shoot, and post-prod) and the whole Mac experience is different from a PC, from a creative workflow point-of-view. I bought MY FIRST MAC this week - Mac Pro, 3 Ghz, 2 Gig RAM, 250 Gig HD, standard video card, and previously owned 2 x 300 Gig Ext Maxtor 7200 RPM. I also bought AE 7, Adobe Web Bundle and FCP Studio 5.1. I shoot with the Sony Z1P and will soon have some sample work on the web.
Lastly, OS X will always be superior to Windows based on the fact that it's built on a UNIX foundation. If I'm not mistaken, Windows code has just built on top of existing code year-after-year. :mad: I think the OS X was a fresh build.

Just to let y'all know, unless someone else knows otherwise, Best Buy makes zero off Apple product sales (that haven't been marked up).
I read this thread and I noted that someone pointed out that BB apparently marks up some items -Airports, Time Machines, etc. I found this odd since Apple controls all the pricing, but eh, not going to question that since those are the facts I'm assuming (can't be bothered to go on a comparing spree).
Anyway, the iPad 2s aren't marked up, thus they make zero.
Each department should be meeting their budget daily. How do they do that? By selling products they make notional margin and that allows that department to meet their budget. On a slow, sh-tty day, a department may only be 70% to budget; on a fast, awesome day, a department may be 110% to budget.
But when you make zero off iPad sales, keeping them away from customers does not help notional margin. Doesn't bring them any closer to hitting budget. The only way they'd make money on that iPad sale would be selling accessories or the Black Tie protection. But that's entirely something else.
Best Buy makes zero notional margin on iPad sales, so they're not withholding stock to meet daily budgets.
I can't explain why they're doing this, but given my knowledge, I can invalidate the claim that managers are hoarding iPads so that they can meet budget every day.
Cheers! :D
This is not entirely true. The apple tv2 best buy sells for $99 and best buys cost is around $90. Also, best buy honors student discounts on apple products. Apple does not reimburse bby for that. You really think bby is going to pay customers to buy apple products?
Anyway, I hate bby. I used to work there. Few of the employees give a **** about the customer.

Just for entertainment, go to a Worst Buy and sidle up to a sales guy giving his pitch to an unsuspecting victim. I only ever go there to see a model in person before ordering online or elsewhere. I do purchase items at local stores who respect the customer and don't tell blatant lies about the products.

I'd like to see your "Mac" model bumped up past the iMac. I think a lot of people, myself included, would pay a premium for the ability to upgrade. In fact, I wouldn't care if they didn't offer a completely new model as long as they offer some "affordable" manifestations of the Mac Pro. So how's this (and go easy on me here because I rarely delve into the technical aspect of things):
Eventually (i.e. by November), Core 2 Duo/Woodcrest across he board:
1) Mac mini: 2 models both with the 1.86 GHz Core 2 Duo
2) iMac: 2 models with 1.86 GHz and 2.13 GHz Core 2 Duo
3) Mac Pro: 4 models; 2 Core 2 Duo-based systems (2.40 GHz and 2.66 GHz) and 2 Xeon-based systems (2.80 GHz and 3.0 GHz). The higher-end Xeon systems would sport the same enclosure as the Core 2 Duo systems (similar to the PM G5) but would come in an anodized charcoal black enclosure.
Any takers?

Well, most of that looks good except that there is no 2.8GHz Woodcrest.

I remember hearing about how it is possible to make multiple cores act like one (Idon't remember where I heard this). Anyways, whether 8 cores acting separately or together like 1 big processor has an advantage depends on the program you use. If the program is multi-threaded, then the cores acting separately might have the advantage while single threaded apps will have an advantage if the cores are acting like one. However, many apps today won't see that much improvement either way (like a simple calculator, or solitare and word processing).
yes, its known as reverse hyper threading. AMD are working on it

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..
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.

I got the Lotus Top Gear race done today. Took me a whole hour. About 40 minutes in i got pissed and turned ABS all the way up and ASM on. It helped so much, but the AI made it difficult to finsh. They'd ram into me and i'd get a dsq. Pissed me off.
If anyone is having trouble, try turning off TCS completely, ABS all the way up, ASM on, and the front brake bias to 10. It makes up for the awful tires they put on it.
I accepted littleman and psychofetus as friends, so if either of you want to trade cars let me know what you are looking for.

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?

What I always wonder is what diplomatic efforts were used to pressure Qaddafi? There were no (as far as I know) threats of economic embargoes, freezing of assets, or other less violent methods to coerce Qaddafi.
As I recall, there was some freezing of the assets (http://www.guardian.co.uk/world/2011/feb/27/gaddafi-family-assets-frozen-queen), though the figures they show make it look like little more than window dressing.
Really, the reason the west wants him outta there is because no one can agree on how to transliterate his name :confused:

But if that happens, they already know everything there is to know about you anyway and have no need to check your Wi-Fi database. They've got your Address Book info, your bank site links and cookies, your email, your personal letters, etc.
The point is that I save on my computer what I consider the computer to be safe enough for, which includes, eg, my e-mails. I simply would like to be given the choice to decide whether I want to save certain things on my computer or not. With that database, Apple did not give me the choice because it did not inform me about this database (if it had told me, I might have run a cron job to delete it, excluded it from my TM backups, encrypted my iPhone backups, etc.).

MS will announce that they are dropping Mac development :eek: :eek: :eek: :mad:
DON'T YOU GET IT ...
... this is the plan Bill G., the NICE GUY, leaves MS with his CLOD BULLDOG in charge AND YOU GET WHAT YOU GET, Balmer cuts the Mac devision and probably a TON of other jobs too and then they announce their MP3 player and all sorts of services !!!
This way their player looks more credible then Apple, for a while anyway !!
