i7 2630 QM or i7 2720QM?

i checked their specs on the intel website, not many differences except for 2GHz/2.2GHz respectively and some minor differences in the "Advances technologies" section... for more info check:

Intel® Core? i7-2720QM Processor (6M Cache, 2.20 GHz))

and

Intel® Core? i7-2630QM Processor (6M Cache, 2.00 GHz)

i know i'm asking for a lot of help lately (sorry for being a nuisance) but i really want to be sure about my purchase thanks a lot guys you've been really helpful with my other thread!

 

If you don't understand the differences under the Advanced Technologies tab, you won't need those. Those specs are for the "advanced" users.

Buy the cheaper.

I went for the 2720QM because of the way better quad turbo (3.0Ghz vs 2.6Ghz on the 2630QM). A 2630QM is more than powerful enough for gaming.

The 2720QM also supports 1600Mhz ram, whereas the 2630QM only supports 1333Mhz. From most accounts the difference is indistinguishable outside of benchmarks.

It really depends what you're doing with it. If you're gaming i'd say stick with a 2630QM, but if you need the extra power or your like me and convinced you might regret it later... get the 2720QM.

EDIT: The 2760QM is replacing the 2720QM, is the same price and is much more powerful, might want to add that to your list.

 

There is no tangible difference between the 2 processors other than one or two additional features 2720qm has, which are probably useless to 99.9% of the users. Bottom line is if you don't know about it, you will never need it. And if you are not doing CPU-intensive works like Video-encoding/decoding, 3D rendering, you probably won't notice a difference.

If you are short on money, get 2630qm and spend on something that could bring you some REAL benefit like a SSD.

 

can't afford an SSD right now is it possible to buy an SSD later on and install that instead of the HDD? when it's a bit cheaper of course

 

The 2720QM I think is getting replaced by the slightly faster 2760QM:
Intel Intros New Sandy Bridge Processors
But it's still not practically faster than the 2630QM, so stick with that.

Yes you can definitely upgrade the hard drive to an SSD yourself, that is easy to do and does not void the warranty. The storage medium is designed to be user-replaceable. Same goes for the RAM sticks.

What laptop are you looking at?

 

i'm looking at the Dell Xps 15 L502x, naturally getting it with the 1080p display

 

by the way, the 2620QM processor has 2.7 GHz... is it more worth it to get that one?

 

Get the cheapest one...

Hi
I have purchased i7 2820QM ES for £170

 

that's not correct. I have 2630QM currently and am running 1866MHz
That's the thing intel doesn't update their pages
before when first time these QM and XM i7s released there was up to 1333 or 1600

 

Relatively useless information since you don't know where he lives let alone his options for purchasing that CPU. Also, ES models are generally not recommended since they lack a few important things such as thermistors to measure temperature and are usually tested to its limits several times, degrading their long term quality. Also, memory speed is useless in any real life situation if you do not benchmark for a living or game on integrated graphics.

 

@sgogeta4
1.I really do not miss any thermistors because this is not XM (extreme) so I won't be overclocking at all I will leave it as it is original.
2.If you talking about long term because they been tested if they are tested they will automatically turn off IN THAT temperature limit
3.And people usualy have laptop 3-4 years and then changing so I do not see problem

4. sgogeta4 you might be unpretending person but you know plenty people on earth have different needs and feelings
and they do not think like it's ok slower buy cheapest , yoou do not need that and that
But again people have different likes and they do what make them happy hm?

 

heard that you can upgrade the processor if you get an ivy bridge once it comes out though... is this true? cause if it is, i'll just settle for the 2630 QM and upgrade it later on

 

No, it is not true. Laptops will not be able to use Ivy Bridge CPU's. It is partially true for desktops, but BIOS has to support it. Don't have a link at the moment, but this was clarified by Intel many months ago.

 

it might not be supported by your bios /motherboard

 

Yes it's for desktops for now
Benchmarks appear of early Ivy Bridge engineering sample by VR-Zone.com
Ivy Bridge, the codename for a processor microarchitecture that is being developed by Intel as the 22 nm die shrink of Sandy Bridge


I have heard about Sandy Bridge-E

 

think i will settle for 2630QM nonetheless. i will use this laptop for gaming, blu-ray movies and the like, so i guess 2630 will serve me well enough. as iEthos correctly pointed out, i want this laptop to last for 3 years... i'm willing to pay that extra bit for a 2720QM but many people told me the difference isn't too noticeable. of course that may change in 2 years time, or even less, because technology is advancing too quickly... and really it's not worth it to play the waiting game cause it never ends

 

@Radi324
I went for 2820 and I will sell 2630
What I can suggest you buy one of these look

 

Only reason its clocked higher is because its a dual core and not quad core like the i7 2630QM.
Also its i7 2620M and not QM.
Q is for quads only.

 

could you please tell me where the 2630QM is ranked on that list?

 

@Radi324.
Oh sorry I just displayed best ones
the medium range is here :
