Does integrated HD 4000 performance improve w/ better CPU?

[crabapple]

I'm currently undecided between a 3rd generation i5 & i7 laptop.

The i7 is roughly $50-$100 more.

Both CPUs provide Intel HD 4000 graphics.

Would spending the extra money for the i7 INCREASE the integrated graphic's performance because it's a faster CPU? Or are all HD 4000 integrated graphics the same regardless of the speed/quality of the CPU?

all HD4000 are the same, and they are only included with decent enough processors, so you will never notice any difference, if you keep looking you might find something with a 650M (or equivilant 7X0M GPU) in the same price range.

Here is a list of all laptops GPU and their performance for your reference

All HD4000 is the same IIRC, but the CPU will be faster.

If you intend to do any form of gaming, get something with a dedicated GPU.

Also, Haswell should be making it's way out now, with a faster iGPU that is almost worth owning.

Depends specifically on the CPU model some CPU are just a little higher clocked. For example,

In the i5-3230m the Intel HD 4000 base clock is 650MHz and max is 1.1GHz.

i5-3380m : Intel HD 4000 = 650MHz / 1.25GHz

i7-3520m : Intel HD 4000 = 650MHz / 1.25GHz

i7-3840QM : Intel HD 4000 = 650MHz / 1.3GHz

The i5-3230m is a pretty common mobile Ivy Bridge CPU where the Intel HD 4000 runs at max 1.1GHz. It's not the slowest speed, but certainly not the fastest. Only the more expensive quad core CPUs has the Intel HD 4000 running at it's top speed of 1.3GHz. However, those CPUs are pretty expensive.

You may want to consider a laptop with Intel's Haswell CPU which has the Intel HD 4200, HD 4400 and HD 4600 integrated graphics core. The HD 4600 is the most powerful of the three which I believe is about 25% more powerful on average than the HD 4000. There is also the Intel HD 5000 series with "Iris" being the most powerful graphics core which is the Intel HD 5200 + eDRAM and it is roughly equal to a nVidia GT 640m GPU, but they will be on the higher end laptops.

So far, the only laptops with Haswell CPU only have the the quad core i7-4xxxMQ series which has the Intel HD 4600. Since Haswell CPUs has only been recently announced, less expensive dual core i5 mobile CPUs should be coming out shortly.

But some hd 4000 GPUs have 1.3 GHz of max speed and some have only like 1,1 GHz of max speed

Still, that's not much difference. And it's max, so they rarely actually get up that high.

This might be gravedigging just a little, though.
