1066MHz FSB P4EE正式發(fā)布 性能全曝
當(dāng)?shù)貢r(shí)間10月31日，Intel正式發(fā)布了支持1066MHz FSB的Pentium 4 3.46 Extreme Edition處理器，頻率為3.46GHz，稍后還將有3.73GHz發(fā)布。目前3.46EE的千顆批發(fā)價(jià)格為999美元，該處理器配備512KB二級(jí)緩存和2MB三級(jí)緩存。實(shí)物如下：

與P4 3.46EE同時(shí)發(fā)布的還有i925XE芯片組，這實(shí)際上就是支持1066MHz FSB的i925X修正版本。以下是i925XE樣板Intel D925XECV的實(shí)物及規(guī)格說明：

搭配DDR2-533內(nèi)存，新平臺(tái)的總線頻率上升了一個(gè)檔次，那么是否會(huì)帶來預(yù)期般的性能提升呢？還是用測(cè)試來說話吧，以下測(cè)試數(shù)據(jù)來自于Anandtech網(wǎng)站，測(cè)試平臺(tái)說明：
AMD Athlon 64平臺(tái)
處理器：Socket-939 Athlon 64
內(nèi)存：2×512MB OCZ PC3200 EL Dual Channel DIMMs 2-2-2-10
主板：NVIDIA nForce4 Reference Motherboard
顯卡：ATI Radeon X800 XT PCI Express
AMD Athlon XP平臺(tái)
處理器：Athlon XP 3200+
內(nèi)存：2×512MB OCZ PC3200 EL Dual Channel DIMMs 2-2-2-10
主板：ASUS A7N8X Deluxe nForce2 400
顯卡：ATI Radeon X800 XT AGP
Intel Pentium 4平臺(tái)
處理器：LGA-775 Intel Pentium 4 and Extreme Edition CPU
內(nèi)存：2×512MB Crucial DDR-II 533 Dual Channel DIMMs 3-3-3-12
主板：Intel D925XECV2 Motherboard
顯卡：ATI Radeon X800 XT PCI Express
測(cè)試結(jié)果顯示，1066MHz FSB對(duì)于性能表現(xiàn)幾乎沒有任何提升，基本上和前輩P4 3.4GHz/800MHz FSB的表現(xiàn)一致。<
