Mgbanwe evolushọn na nkwukọrịta CPU-PCH
Dị ka akụkụ nke usoro evolushọn, isi ụzọ nkwukọrịta dị n'etiti CPU na àkwà mmiri ndịda, nke bụ ụgbọ ala DMI (Direct Media Interface), nwetara nkwado maka ọnọdụ PCIe x4 Gen3 na arụmọrụ nke 8.0 GT/S. Na mbụ, na Intel C610 PCH, a na-eme nkwurịta okwu n'etiti processor na usoro nhazi na PCIe x4 Gen 2 mode na 5.0 GT/S bandwit.
Ntụle ọrụ mgbagha sistemụ nke Intel C610 na C620
