E5500虽然发布很久了,但是从没投入市场. 至少我没看到过有人卖,更没看到有人买.
我推测的原因是:是5400的马甲，E5500仍然使用45nm Wolfdale核心，只不过主频略微提升到2.8GHz，只比现在的E5400高出100MHz，其他规格均与现有的E5000系列型号保持一致，比如双核心双线程、2MB二级缓存、800MHz前端总线、热设计功耗65W。疑为5400超上去的。
同价格的E6500K更好卖,不锁倍频而且默认主频就2.93GHz了,性价比比E5500更高.所以E5500在市场上销售表现不好,就不怎么出货了.
不推荐！
推荐用i系列的！
GOOD LUCK ！！！

intelE5500这个CPU目前已经淘汰了，现在只能算是最低端的CPU，和现在主流的CPU性能相差几倍，市场上已经没有新产品出售了，下面是intelE5500这个CPU的参数：
CPU主频：2.8GHz。
核心数量：双核心。
线程数：双线程。
二级缓存：2M。
插槽类型：LGA 775。
针脚数目：775pin。
还可以，运行大型3D游戏不在话下，配P43主板，内存DDR3 1333 2G，显卡GTS250 512M显存256位宽系列就可以了，电源额定350W足够，运行游戏流畅。
