Can someone clear this up for me please. As I understand the new Intel CPU's have integrated GPU's so that they use that for normal usage instead of a dedicated graphics card as it's more energy efficient.
Is the only difference between a P67 and H67 board is that the H67 has the ability to use the integrated graphics without a dedicated graphics card also installed? Is this right and is this the only difference between the 2 chipsets?
Depends on your needs, the P67 is the overclockers board so allows overclocking of the CPUs the H67 doesn't. Also the H67 allows access of the inbuilt GPU on the CPU the P67 doesn't. If you don't plan on overclocking buy the H67.
Cheers for the info. I still take it the P67 chipset still allows the integrated GPU to be used but also requires a dedicated GPU as well.Quote:

H61 is a cut down H67.
Z68 is the real enthusiast chipset, due in a month or 2.
Yes, in laptops... Like Nvidia Optimus. This hasn't been enabled on desktops, shame.Quote:

The Z68 is due in summer and is basically the H67 but with overclocking unlocked.
the thing you are getting mixed up with, the ability to run on the onboard graphics and have a card take over under load is something from ati and nvidia, nothing to do with intel chipsets.
It was called hybrid crossfire/hybrid sli and has been pretty much quietly dropped by both companies, the main reason being that current graphics cards are running at far lower idle power levels to the point that the saving is tiny now.
It has turned up in a few laptops but that's all.
Cheers for all the answers. Much appreciated.
It's worth reading this article on Anantech about the forthcoming Virtu from Lucid which is implementing software that allows use of both the integrated and discrete GPUs on H67 and Z68 boards:
