I was mixing cpu+chipset=arm soc. A 10G port takes the same PCIe lane as a 1G port, particularly if you have PCIe gen4+ or are willing to potentially lose a bit with gen3. Similarly with power, EEE doesn't use the power if its not needed. Which for users on short runs, or with 1G switches the power utilization will be the same as a 1G port. And given that we are talking 200W parts, a watt or two for 10G isn't going to be missed. And probably more of the motherboard manufactures would put 10G nics on board if there weren't a dearth of 10G pci nic chips from manufactures not already selling PCIe nics as high margin products. AKA intel selling its 10G part for more than the rest of the parts on the motherboard is going to keep motherboard manufactures from putting it on every motherboard. Its sort of been a game of chicken, which will explode violently when the patents expire and a company like etron or asmedia starts producing them. (both of which have shown plenty of inhouse capability for producing high speed phy/etc interfaces).
