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 !

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.

Double memory bandwith.

Max RAM E3: 32 GB
Max RAM E5: 375 GB.


Savvy?

they're both phantom chips

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).

Max RAM E5: 375 GB.

Huh?

375 / 8 slots = 46.875GB per slot.

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.

Besides those processors, Intel proudly announced a quad-socket version of the Sandy Bridge-EP, the E5-4600

E5-1600 series - 1 socket
E5-2600 series - 2 socket
E5-4600 series - 4 socket

Yay. Another nomenclature change. Intel is horrible about those.

hi, does anyone know if E5-16xx processors support registered ECC memory?
thx.

yes, I asked Supermicro tech support the same question and they confirmed

375 also implies one or all ram dimms are odd numbers and as the only odd number RAM dimm I am aware of is 1GB maybe there is a special mobo out there with 375 ram slots :D

E5-1600 series - 1 socket
E5-2600 series - 2 socket
E5-4600 series - 4 socket

That's a..strange changes. Where will be E7's place? Will E7 just mean better RAS in the future? I quite don't understand their approach
