P37X Haswell vs Broadwell

Hi, quick question: I'm deciding between these two models of the P37X:
1. http://www.amazon.com/Gigabyte-Lapt...3?ie=UTF8&qid=1435526384&sr=8-3&keywords=p37x
2. http://www.amazon.com/Gigabyte-P37X...6?ie=UTF8&qid=1435526384&sr=8-6&keywords=p37x

It seems to me as though the only difference between the two is the CPU. Number 1 is equipped with the i7-4720HQ Haswell where as Number 2 is equipped with i7-5700HQ Broadwell. How big of a difference is there between the two? Which one is better and why? Would I save a significant amount of battery and reduce the CPU temperature significantly by going with the Broadwell model?

Now, I know some of you might be saying, "might as well buy the latest version," but I already ordered the Haswell model and it was too late to cancel, so it's shipping. I'm wondering if it's worth shipping back to get the Broadwell model. Thanks!

 

Not worth cancelling and reordering over.

Here's an intel spec comparison over the 2 CPUs, notable differences: the 5700 is 100mhz faster base frequency but 100mhz slower turbo frequency. - also the 5700 is a 14nm chip, which 'usually' translates to slightly lower power useage and slightly lower temperatures.

however in the real world, I don't think you'll notice a difference between the two at all.

however, the 5700 model does come with 16GB of ram, so there is that... not that can't shove 16GB of ram into the 4720 model of course!

so if it's going to eat away at your conscience, send it back. however don't worry about getting a raw deal or anything, because you're not, the 4720 is just as awesome as the 5700.

 

Awesome, thank you! I just want the components to last as long as possible, so I'm thinking even a couple of degrees Celsius decrease in temperature should help with that?

Another question that I have, and I don't know if you can answer this, is why choose the P37X over the P35X? Aren't they pretty much identical except P35X is lighter and smaller and comes with a 2k option? Does the P37X offer better temperatures thanks to its larger volume? Is it better with noise emission? What about battery life? What justifies the fact that the P37X is 1 pound heavier?

 

P37 being a 17" does give more room for heat to go and will benefit for a few degrees less in heat. Noise I'm sure is a wash.

Since I went P37W w/ Broadwell with mine, I was not able to get a higher-res screen. That being said, I don't care as you'd have to step games down a res anyways. Absolutely in love with this machine.

 

Broadwell isn't much more than a die shrink coming from Haswell. Very minor differences. You may as well stay with your Haswell order, unless you want to return it for when Skylake is released, which stands to be a more significant step up.
