[citation][nom]thearm[/nom]"This list of high end x79 boards seems top be missing the rampage iv extreme."I was wondering the same thing. I was about to purchase the rampage iv extreme then I saw this story. I was hoping to see it compaired with these boards. But, maybe it's in a league of its own.[/citation]
It uses the same chipset and Asus doesn't differentiate integrated components on a per board testing basis. It will almost assuredly perform at the same level the other boards do, it just has a brand name unscaled cost and different tweak software.
In general, the entire x79 platform seems poorly executed to me. For having over twice the transistor count of a Sandy Bridge chip, the E line does not have performance to match that much of a die size increase, coupled with the base TDP being as high as it is, I would expect many more cores or much higher clocks out of them, especially considering they don't waste die space on integrated graphics.
That and the motherboards to go with the platform are all extremely overpriced. It is understandable that a new socket type has a lot of manufacturing overhead, and 4 channel RAM is magnitudes more complicated circuitry than dual channel, and having the PCI lanes support almost three times the bandwidth and channels is costly. But it isn't triple the price of a reasonable z68 motherboard costly.
