Are the new i5 and i7 processors Dual or Quad Core?

[thiagos]

I am a bit puzzled about my new MacBook Pro. I got the i5 but I have read online that these are actually dual core processors. What is the difference between the Core 2 Duo and the new i5s then?
Also I have a 27" iMac with i7 Processor, those are quad-core, any difference in processing power besides the clock speed?

The mobile i5 and i7 CPUs are Dual Core, but can have up to four concurrent threads.

The desktop i5 and i7 CPUs in the iMac have four cores and the i7 can have up to eight concurrent threads.

So what is the advantage of the Intel i5 over the C2D?

The i5 offer roughly a 20-25% performance boost over the C2D.

While Apple uses only dual core versions of i7 in MBPs, Intel also has quad core i7 mobile processors. Many PC manufacturers offer those in their laptops. More info is available on Intel web site here.

It isn't about the clock speed; as you know, i5 and i7 processors are at a slower clock than the latest C2D chips, but they are far more efficient. Also, the number of cores available doesn't provide a noticeable improvement in speed for most processes. Multiple cores is like RAM; the more you have, the better suited the computer is for running multiple applications simultaneously.

Basically the i5s are cheaper. They're no faster (in fact slower by some benchmarks) than the 2.8 and 3.06 C2Ds.

I do run some quite heavy applications such as Adobe CS4, Aperture and Final Cut usually simultaneously so the quad core would have been extremely suitable to my needs.

If the i5s are cheaper, why the price increase? Apple needs to make up their mind, they lower the prices and then they raise it right back up. On top of that they use Pro for everything now, marketing at its best.

Here's Lenovo's

It's only $3500

Holy crap this is so wrong. The difference between Arrandale and Penryn (Core 2 Duo) is 2 years of advancements in processor technology. The i5 will be more efficient and thus do more work per clock cycle vs a Core 2 Duo even clocked at the same speed in GHz. See:

Yeah. But this is a special monster machine with dual screen It's a real PRO machine (a mobile workstation). DELL and HP offer those too.

the i5's are cheaper but since the USD is weaker it probably costs more to produce them in china and to transport them...i know that all of the Australian prices fell by $100-$400 because of the strong Australian dollar. The UK prices rose by a lot because of the weak British pound.

exactly right, there is no way that the Penryn c2d chips are superior to the Arrandale chips. Arrandale is superior in every way

Did you even bother to look at what you were linking other than the price?
