Hyperthreading is the latest name for an Intel technology that effectively allows a single physical core to run as two virtual cores. So in the current iMac range the i5 processors have 4 physical cores and can run 4 threads in parallel. The i7 processores have 4 physical cores but can run 8 threads in parallel thanks to hyperthreading.
So Hyperthreading only really offers an advantage with applications that are designed to run on multiple cores. Unfortunately things aren't entirely that simple as there's also the slightly faster clock speed of the i7 and Turbo Boost to consider.
Turbo Boost effectively lets a processor speed up when it's not using all of its cores by 'shutting off' the cores that aren't in use. Off the top of my head the i5 3.1Ghz can Turbo Boost to 3.4Ghz while the i7 3.4Ghz can run to 3.8Ghz. The real world difference is relatively small but can be worth a couple of frames a second in a game or a few seconds off a benchmark.
Hope that helps a bit, if there's anything there that's not clear just ask.

And that's still correctly connected in Interface Builder? If you check the value of abc in awakeFromNib inside LoginRegisterViewController is it nil?

Hey everyone,
I read most threads in this forum about overheating, but it turned out that's not at all a concern in a daily basis. What is a concern, however, is the instant fan noise whenever the laptop gets under load.
It is constant when running games (always at 6000 rpm). I've tried Call of Duty IV, and Starcraft II. Also Crysis II via Boot Camp.
It may happen under Facetime.
It may happen if you leave a flash animation running in a tab.
it may happen with AirVideo Server (serving to an iPod).
Turns out there's really no middle ground for this fan. It is either audible, or isn't. With 2000 rpm you know it's there, but frankly that's barely a concern. Sometimes it turns on suddenly and goes to maximum speed in seconds, stays there for a minute or two, then drops down.
So I guess that ANY heavy load will come with fan noise. Here's what I need to ask then.
- Is this a given for Sandy Bridge?
- Do you have this kind of noise in your C2D MacBooks (Air included)?
- Is it better when you have more fans involved (larger MBP's, iMacs..)?
Like I said, it hasn't been that much a concern for most uses, because they stay under the radar. The MBP gets hot but that's not even a problem. What I get is there is a clear threshold between what you can do (silently) and what produces noise. I stopped playing games because I really cannot do with that much noise. Turns out the GPU can roll with a lot of games, but I thought the noise wasn't included. Plus I'm afraid I'll damage the laptop if the fan is on for so long.
I'm thinking I'd rather have lower processing power and silent operation. I can take a longer iPhoto import if I don't hear this fan. Help?

Running 10.7 DP2. iTunes runs fine, until I plug in my iPhone, at which point iTunes beach balls uncontrollably.
Didn't have this problem before, this randomly started ... help?
I'm not having any issues with my iPhone4 and iTunes. I suggest you file a bug report with the system log attached.

Hi thanks for looking at this, I tried what you said but Im still not able to receive the email, could there be a server setting or email setting that I need to enable?
thanks
Worked for me, sent to my gmail email address. I didn't use the form, just hard coded the variables on the email script.

it has nothing to do with products, this is to do with brand strength.

I am planning to Switch (upgrade) from PC to Mac but I still need to run some PC programs.
The only thing I hear about Virtual PC is that it�s terrible slow.
I am planning to put 2 Gigas of ram on my new Imac 20".
1 giga dedicated to the Virtual PC.
Does anybody has an experience if by doing this I should see a lot of performace Gain on Virtual PC?
I�am not planning to run games just normal applications (some design an graphics) but I need to run them on PC envieroment to ensure compatibility.
Thanks in advance for advice.

Does anyone really use Illustrator CS to it's abilities to create vector artwork on the scale of photographic portraits?
My Illustrator class instructor does and one of our assignments was to do something of that depth. I'll try to dig up the website, if you're interested.

A big problem with the big megapixels is the amount of storage they take on your phone. You cannot adjust the megapixel size down with a phone camera like you can with a point & shoot camera.
I think you can adjust the resolution on Windows Phone 7.

Pretty much every phone I've had has has adjustable resolution settings.

This will NOT work for "any iPhone/iPod touch." This needs to be made clear for anybody who thinks this is a one-size-fits-all solution for everybody.
Apple cryptographically "signs" firmware releases these days. This happens during the restore process, and unless Apple signs off on the restore, you'll get an error message. Even if you could bypass the error message, without the signatures specific to your device for that iOS version, your device would never boot up.
Apple prevents downgrades by refusing to sign anything but the latest version of software. This is where Saurik's SHSH collector and TSS server come into play, for those that take advantage of his services.
The reason it worked for YOU is because you have a second-generation iPod touch and you were downgrading to something less than 4.0. Apple didn't start using device-specific (ECID-based) SHSHs until 3.x on iPhone 3GS and iPod Touch 3rd-gen, and 4.x on all other devices that support 4.x (including iPhone 3G and iPod Touch 2nd-gen). So, unless you are collecting your SHSHs for each Apple software release, if you are on 4.2.1 on your iPod touch, you would be able to downgrade to 2.1.1 like you did, but you would not be able to downgrade to 4.1 or 4.0.
Also, you didn't technically need iREB for this. All you used iREB for was to get the iPod into DFU mode. You can do that yourself, manually, using the power and home buttons...instructions for doing so are in abundance on-line.
If you have an iPhone 3GS, iPhone 4, iPod touch 3rd-gen, or iPod touch 4th-gen, you can't downgrade to any release without the corresponding SHSH for your device. Period.

If youre just looking for Pokemon Id say get a DS Lite on ebay for cheap rather than a DSi. Then you can hold out until the 3DS comes down in price and more games are released if you still need to get your mobile gaming fix.
I am playing Black on my DS Lite right now. I can tell it wasnt designed for the screen on the Lite though, as in battle the lettering in the pokemon names is really cramped.
The benefit of the Lite is that if you have any leftover Gameboy Advanced games you can still play them on it. I play Super Mario Bros 1 and 3 on my Lite which was the main reason I havent upgraded and probably wont upgrade for a while.

Sell online using PayPal? Check out their supported hosts.
I am a Yahoo store developer and am partial to that platform for small business. That is probably out of your price range.

There shouldn't be any qualitative difference btwn DV files imported on older / newer machines and the import from tape is in real-time, so an old machine will crank away just as well as anything. The new machine will make a big difference when actually transcoding, editing, and exporting.
Seconded. No need to wait.

don't really know which to get as i really like the big capacity of the classic , but on the other hand the small formfactor , fm radio , camera 40bucks lower price .. dunno .. which one would you get
