which is better the nVidia GT 650M or the GTX 660 and by roughly how much? i'm pricing up an MSI GE70/60 and the only difference before customising anything is the graphics card with just a $50 difference

you meant GT 650M vs GTX 660M, right?

(Jun 10 '12 at 11:51) junky junky's gravatar image

GTX 660 has more GPU speed but 512MB less RAM and 500 less MHz on the memory clock.

660M is better but over clock to 1000MHz and it will be better :)

less RAM? the one i'm looking at has 2048mb DDR5 same as the 660M?

the title when you look true google is "GTX 660 vs GTX 660M" something like that.

By rule of thumb, I would get the more expensive one if you can afford it, they're more expensive for a reason.

there's like a $50 difference between the one with the GT660M and the one with the GTX660M, they both have 2048mb of DDR5 RAM so i don't really get it? I'm leaning in your direction though by going for the GTX660M, correct me if i'm wrong but isn't it the newer card?

They are both the same age pretty much, the GTX Usually indicated better performance, I would go with that if I were you.

By a rule of thumb, I'll suspect the more expensive one. Here is an explaination of the difference between the GT 650M (GDDR5) and GTX 660M: GTX 660M vs GT 650M GDDR5

In short: The GT 650M GDDR5 model is almost the same as the GTX 660M. It has the same memory speed and bandwidth, but less 100MHZ in core speed. It's highly overclockable and can reach 660M's clocks and beyond. The TDP might be higher in this case, as - maybe - it's not meant to be in these clocks - but it's only 100MHZ so I doubt it has significant impact on TDP

given that it's so marginal i could go for the GT650M and use the saving to get a better wireless card sounds like a plan i'd say

that's what I'd do. Don't get me wrong - there is a good 10-15% difference in performance as it's the MHZ difference, but you can OC the GPU. Moreover, there is that thing that is called Turbo Mode which automatically OCing your GPU by up to 15% depending on the surrounding heat and power consumption, but it also depends on the maker of the laptop to enable it in the bios

Anyway, I suggest that you consider the HP dv6t-7000 too and the Sager NP 6165. The HP has 33% off now and you get GT 650M GDDR5, 1TB HDD (although 5400RPM), 8GB DDR3 and I7-3610QM + FullHD screen for 905$. You can upgrade the HDD and more staff: http://www.gaminglaptopsjunky.com/back-hp-pavilion-dv6t-7000-15-6-gaming-laptop-intel-ivy-bridge-i7-3610qm-nvidia-gt-650m-1gb-gddr5-gpu-8gb-ddr3-memory-1tb-hdd-804-fullhd-display-upgrade-900-33-coupon-code-nbg5247/ The dv7t-7000 has two HDD slots so you can add your own SSD which is great: http://www.gaminglaptopsjunky.com/back-hp-pavilion-dv7t-7000-17-3-gaming-laptop-intel-ivy-bridge-i7-3610qm-nvidia-gt-650m-2gb-gddr5-gpu-8gb-ddr3-memory-1tb-hdd-fullhd-display-upgrade-1005-33-coupon-code-nbg5247/

The Sager has also two HDD slots and is designed to be customized so it should be easy - find it on XoticPc site (that's the best price I've found)

i really don't have any confidence in HP any more after living with my current laptop for four years also my brother has the model that came just after and he's not satisfied either. More over my sister picked up a HP at a clearance price against my advice and she's having issues with it for gaming despite it being above spec for what she plays i.e Minecraft. I won't put money into a HP even if it's at a good price as from my experience i will have issues with it down the line and considering my budget i don't have to compromise.

we're talking on the same thing over two different threads? I don't HP is a compromise in that case, but see the reply in the other thread
