How does mobile i7 fare vs desktop i5

Hi!

Excuse the title, didn't know what to name it exactly. My question is how does a f e i7 2630 or i7 2720 carry its weight vs a i5 2500 desktop cpu?

Reason I'm asking is because I have a i5 2500k going at 4.8ghz paired with a gtx 570. I will have to ditch my desktop soon and will use my 570 as a eGPU and was simple wondering if a i7 2630 or 2720 will carry it's weight in games. Aka not "bottleneck" the gpu, although I doubt it will.

I understand that the gpu won't be able to work at x16 but I just want to make sure that the gpu halts the performance before the cpu does.

 

The 2760QM is on par with a stock 2500K, so remove your OC and see if there's any bottlenecking there

 

A 2760QM isn't an option on the models i've been checking out atm but might be later. At the moment the i5 2500k at 3.3 stock doesn't bottleneck anything in my computer so anything comparable to it in stock will do more than well for me.

 

My 2920XM compares to a stock 990x check sig

 

No, the processor's not going to bottleneck your game experience. Those processors probably wouldn't bottleneck a full-speed desktop GTX 570, and when it's running as an eGPU you've got nothing to worry about.

 

since its the same generation of chips, you can actually compare them clock-for-clock . Remember that a laptop chip is just a desktop chip that is VERY good at running at low-voltage* while still maintaining respectable clocks speeds.

TECHNICALLY, the laptop model would be more likely to throttle...but that is technicalities.

*not entirely sure if they actually run at lower voltages....

 

Bear in mind that you have overclocking headroom with the 2500k. They can easily hit 4.5GHz if you have a semi respectable cooler.

 

While the benchmark scores indicate that the mobile i7 2760QM is in the same performance level as the desktop i5 2500K, I highly doubt it - even if your mobile cpu was running exposed on a desktop with a cooled stream of air blowing right on it.

With a base clock of 2.4GHz vs. 3.3GHz I am more of the opinion that the mobile processor will perform at least 35% below the desktop processor on a continuous basis.

I am almost 100% sure your gpu and gameplay experience will be bottlenecked by the i7 2630QM or the i7 2720QM vs. your highly overclocked desktop i5 2500K running @ 4.8GHz.

 

in games 2760qm is about on par with 2500. under heavystress the 2500 will be better since it doesnt throttle.

 

Both are Sandy Bridge quad cores. You can compare them clock-for-clock.
