两代旗舰大比拼：i7-2700K vs i7-3770K

继国内硬件论坛Chiphell的爆料王bigpao007后，国外论坛hwbot上次提供Ivy Bridge完整资料的网友也拿Core i7 3770K与Sandy Bridge的旗舰Core i7-2700K做了一对一的直接对话：

虽然选取的测试项目说服力并不是最强，但也能看出来Sandy Bridge与Ivy Bridge在频率相近时的性能差距。

可以看出在CPU理论性能方面，Ivy Bridge作为Tick（即使是Intel官方宣称的Tick+）和Sandy Bridge差距并不算大，平均优势只有3%。而集成的核芯显卡（IGP）部分，DX9.0c性能提升幅度大概有35%左右。

此外就是功耗了，Core i7-3770K的TDP为75W，而Core i7-2700K的TDP为95W。而由此带来的超频优势据之前bigpao007的爆料也十分可观。
