Why is a laptop i3 clocked higher than a laptop i5?

[Tron]

Most laptops I see with i5 are clocked at only 1.7Ghz, turbo is 2.6 but i3 I see at 2.4Ghz.

I'm thinking of getting this makeshift laptop: [url=http://www.onlinecomputer.com.au/product_info.php?products_id=10779]http://www.onlinecomputer.com.au/product_info.php?products_id=10779[/url=http://www.onlinecomputer.com.au/product_info.php?products_id=10779]

Because they are less cores. Some of the i3s if not all of them hyper thread so you have 2 cores, but it acts like 4. Most of the i5s are 4 physical cores, on the laptops there are some weird ones, but in general that is what it is, that is also the way it is on desktop models. The more cores the better, as long as the program you are running can use more cores. Games such and battlefield 3 and crysis 3, along with many productivity applications can use more than 4 cores. Older games are normally limited to one or two cores, so the faster they are the better, because it doesn't care about the other two. Hopefully this cleared it up some for you.

Also with four physical cores you will get higher tempretures at higher clocks. It isn't really about the clocks because as you can see in Linus and Slick's benchmark the FX-8350 is clocked higher than the I5 3570K and yet the I5 3570K can get similar or even better frame rates!

Core i3 and Core i5 in laptops are the same chip, Core i5 has turbo boost enabled and something else I can't remember (I think AES instruction set or something) but they are basically the same dual core die.

I'm unaware of any quad core i5 laptop's

Food for thought that clock doesn't matter as much as it used to. Still matters but not as much.

you can't compare between different architectures.

Then compare a 2500k and a 3570k, both perform similar, with a slight improvement in the 3570k.

I was just saying that it is not always about clock speeds!

It's actually because the specific i5 processor you linked is a low-power one with a TDP of 17w, which is aimed for ultrabooks and tablets. The i3 on the other hand is a notebook-oriented CPU, so there's more thermal headroom. Same reason why desktop i3's are typically in the 3ghz range. That i5 does have turbo though, as mentioned above.

On a side-note, core count is actually the same, all mobile i3's and i5's are hyperthreaded dual cores. Architecture is identical, I wouldn't be surprised if both units are based off the same die too. It's just that the i5 is binned higher, so it can run at lower voltages to meet the thermal specifications at those speeds.

Just for future reference, cpuboss is one of the most inaccurate methods of comparing CPU's. All they do is compare passmark benchmarks which in itself says next to nothing about performance, everything else seems to be an automated comparison of specifications.

The i5-3230m has hyper-threading. (http://ark.intel.com/products/72056)

All of the mobile Core i5's have hyperthreading, it's only the desktop variants that don't.

I do not know much about mobile CPUs, just that my i7 has 4 cores and hyperthreads to 8.

I concur with that thought, remember when AMDiddles said that clock didn't matter back when it did?
