Which one is better for watching movies and gaming a lot. Also I can't find very many laptops with the 620m cause I guess not very many have come out.
Core i7-620M vs Core i7-720QM

IIRC, the 620m is a dual core with HT so it has 4 threads. The 720m is a quad with HT, so that has 8 threads. The 620m is clocked much higher, but at multitasking the 720m wins hands down.

I would go with the 720m. I have it and its a freakin beast. Also you don't have to worry about the low clock speed, turbo boost can kick it up to like 2.0-2.6 when the speed is needed.

For gaming, these would be your best bet.

The difference between em is that one comes with a smaller hdd and some accessories.
I chose those because they have the 720's and a mobility 5870.

I have the new i7 620m in an alienware laptop and it is amazing! It's so fast is ruined my old laptop for me. I just sit and yell at it for how slow it is. It turbos out at 3.33GHz so I feel that it makes up for not supporting 1333 ram. I've used the 720 and after some short clicks it seemed the same to me. The same being fast as ****. Ive seen on other forums people saying the 620m would get slightly better battery life being that it has less cores. I think it might be better for gaming and entertainment because of that fact and the fact that you don't really need 8 cores for entertainment. 8 cores would be mainly for people doing more professional work...and from what I've seen they are the same price.

Just to correct a little bit of information -the 720QM is not "8 cores"

. It is a "Quad-Core with Hyper-Threading".
In my opinion, for gaming and entertainment purposes, you can't really go wrong with either case. For these purposes, I'd be looking more at the graphics card than the CPU. And you wouldn't really be gaming on battery on these systems anyways

And if "battery life" is important, you wouldn't be looking for a "gaming system" to start with

I have the i7 720qm, and it is a pretty solid mobile processor, with turbo boost up to 2.8 it has plenty of power for gaming, i bought a lenovo y560 with the intention of using it for school, and well, it replaced my desktop for gaming. it may only have a 5730 gpu, but it works. i hook it up to an external monitor and run BF:BC2 t 1920by1080 and run verything on med. if you want to use the standard display on the laptop you can run it at high. it is a solid platform once you get rid of the extra bloatwear http://www.newegg.com/Product/Produc...-777-_-Product

Wow, bump from the dead.
It's the GPU that's going to make the biggest difference in gaming not to mention that the 620m will outpower the 720qm in the majority of tasks. The number of cores and threads will have a minimum impact on gaming and movie watching. That all changes if we were to talk about encoding or other heavily threaded tasks. Raw GHz and most powerful GPU is what is going to win here...

Huh?
Turbo boost on the 720 is 1 core to 2.7 and subsequently lower clocks per core after the first...
The Dualcore is i7 1 core is boosted...
You cant add up the speed of the cores and say its so and so ghz
it doesnt work that way...
yah.
But the 620m is fast.
but the 720m is future proof.
In reality the 620m is faster
(and is used for business)
