hi,


does anybody explain why the price is triple between this 2 cpu ?

xeon E5-1620 and xeon E3-1290



it seems, the features are the same, aren't they ? Even the cheaper seems to very better than the more expensive one !

thanks for advice.
 
Xeon E3 is based on the desktop Sandy Bridge platform with 2 channel DDR3 memory controller. It also has 16 PCI Express 2.0 channels on the CPU in addition to the ones on the companion chip.

Xeon E5 is based on the new Sandy Bridge EP die with 4 channel DDR3 memory controller. E5 chips feature 40 PCI Express 3.0 lanes on the CPU in addition to ones in the companion chip.
 
In addition to what IntelUser stated:

The E3 supports only single socket systems.

The E5 supports dual and possibly quad socket systems (depending on chip).

Unless they swap naming conventions again, I wouldn't expect anything with an e5 designation to be a capable of anything more than dual processor functionality.

The 4+ capable ones are typical 7's (E7, the older 7xxx series, etc)

Thats what I thought as well. But I do see mention of quad socket support for E5s. I hope I can get some conclusive proof on that.
