Why do so many say the i5 does not have hyperthreading?

Hello,
So many have posted here that the i5 does not have hyperthreading and even turboboost
it does
I have a Late Q4 11 i5 2430m and it has both
on my Win 7 it has 2 cores with 4 threads running
I have a desktop CPU monitor that shows 4 cores ( I know its 2 cores with 4 threads)

Example ( I read many articles and posts like this )

Quote :

All Sandy Bridge Core i5 processors have hyper-threading disabled, and all Sandy Bridge Core i7 processors have hyper-threading enabled. This is a major feature difference of Core i5 vs Core i7 processors, and it will give the Core i7 products an advantage over Core i5 processors in some heavily multi-threaded applications.

Wrong! http://ark.intel.com/products/5345 [...] _40-GHz%29

So are we going to update the discussion?

Desktop core i5's are quad core no hyperthreading.
MOBILE i5's are dual cores hyperthreaded to 4 threads. You also have a laptop, please do some research before posting

We are if not everyone is referring to the DESKTOP core i5 cpu's, NOT MOBILE!!! >_<
MOBILE ONES: http://ark.intel.com/products/series/53247All hyperthreaded
DESKTOP: http://ark.intel.com/products/series/53248 Not hyperthreaded.

LOL why don't you do research

1st off most people in 2012 own Laptops, How would I drag a desktop to work and else where?

second the articles I read were from early to later in 2011 ( its only January 2012)

Third I hate people who post "do your research" on a forum where you are supposed to discuss and learn.

If you know so much why not share and teach instead of being SNOOTY?

Most people in this specific forum who are talking about overclocking or switching to the i5-2500k etc. Please understand that you are talking about the mobile core i5, not the desktop core i5.

ummm so what?

you have a 2 core chip with hyperthreading thats worse than the desktop i3. happy?

I think we just need to chillax here.

98% of posts about a i5 refer to the desktop processors. Unless the OP specifically refers to notebooks/laptops etc then it is de facto regarded as desktop.

Hyperthreading is only available on the mobile versions. Not desktops, regardless there is no comparison between both of them.

OK I get it, only Gamers who are 12 to 17 here and a Laptop processor is not a "CPU" to be discussed so posting a discussion about them is pointless. Should of not joined since I'm over the Drinking age eh? Sorry and ignore me then,
Bye

You can start a discussion about the mobile versions, its just no one really does it.

This is so herp derp, freaking out over nothing.

You accused others of not knowing by your OP, if you have a query it is prudent to let others know of you platform ie: desktop or laptop so as to avoid the silliness we have all become.

For laptops and notebook section of the forum, click here: http://www.tomshardware.co.uk/forum/forum-20.html

As previously said, anything on the hardware section of the forum is generally considered to be talking about desktops unless otherwise stated. Not to mention the processors actually have different names..

In The SandyBridge (most recent) range of CPU's there's:

Laptop i5's:
Core i5-2xxxM
Core i5-2xx7m

Desktop i5's:
Core i5-2xxx
Core i5-2xxxK
Core i5-2xxxS
Core i5-2xxxT

Then the older range consists of the Nehalem CPU's. But I wont bother to list these, you can use WIKIPEDIA for more info. I'll even provide a link

Lets be fair, amuffin is a member which I frequently see in these forums and tends to give good advise on almost every post he goes to.

People make presumptions, so it is down to you as a user to specify any details such as which platform you are refering to/using.

Throwing pointless comments such as "most people in 2012 own laptops" is just a waste of time and has no place or purpose; regardless of if this is true or not, looking around on the site a little you should have noticed that the majority of all discussions here are to do with desktops, and as such people will pressume you are on about them too.

Also, when amuffin said "do some research" it was put in there to try and avoid pointless posts on the site, such as this.... if you would have actually spent a decent amount of time looking into this you would have found your answer, rather than what appears to be lazyness.

Can I just say, there is a Mobile section to this forum.

As far as this section is concerned, all i5's are without Hyperthreading.

People post laptop questions in the laptop section. Unless they choose not to, and it gets moved to the laptop section.

So, your argument

Most people in 2012 use laptops

is invalid.

Kthxbye

To be fair, the OP has indicated an i5 processor that is hyper-threaded. So he's right, inasmuch as the definition goes.

However, it's not info we're particularly interested in...I think in general when we say on this forum 'the i5 doesn't have hyper-threading' we're setting it apart from the i7, which does. Of course, by this we mean the i5-2500K and the i7-2600K / 2700K...and the distinction is important for a gamer or a someone using multi-threaded applications.

HTPC: G620 / P8H61-M LE / 2x2GB Ripjaws X / Be Quiet! 480W / Corsair Nova / HD 6450 Passive / GD06B

Really? Someone started a thread just to basically say a mobile i5 is "similar" to a desktop i3 (2 cores/4 threads) and rub it into ppl faces?

This thread is bad and should feel bad. It should be bulldozerized

Also DRFP having read your first post, you came across very agressively pointing out that everyone was wrong, actually everyone was talking about a different topic. The very fact that 'everyone' was talking about non HT i5's indicates that most are talking about the desktop version.

Had your original question been far less excitable in its wording then the responses would have been different i'm sure.

By the way most enthusiasts are not 13-17yr old gamers... try not to tar everyone with the same brush.

This is similar to the M GPU's the mobile i5 should really be an i4 in my opinion to avoid this kind of confusion.

1st generation desktop i5s (6xx series) are all dual core with HT except the 750 & 760.

21.......not that age really makes any difference other than potentially more years working with computers. But since technology is constantly changing anyway, no one is really that far behind

I might be wrong, but isn't the i5-6xx series discontinued now? No longer able to purchase from retailers? (Codename "CLARKDALE" )
