What is the difference between a V2 and a non V2 E3 processor?

Hi All,

Anyone know the difference between an Intel E3-1240 and
and Intel E3-1240V2 processor? (I am not having much luck
with Google or Intel).

Many thanks,

Compare them in these two tables.

Hi JJ,

I did not realize that the Non-V2 was Sandy Bridge and the
V2 was Ivy Bridge. Meaning that the V2 is lower power and
has a faster memory bus. (Same price too.) I will go with
the V2.

Thank you!

I can tell from the ark entry, it's LGA1155, so you can't get
yourself in too much trouble. LGA1155 uses DMI instead of QPI,
and is only suited to single-socket motherboards.

That particular processor, has no internal GPU inside the CPU,
so there'd be nothing to drive the FDI bus. If the motherboard
has rear DVI or VGA connectors, I don't think they'd work
with the E3-1240V2. In cases where a processor has no
internal graphics, that means either a motherboard GPU (used
on server boards, usually a pretty weak VESA solution) or
the usage of an add-in graphics card.

In the table here, you can see some E3-1200 series have GPU
and some do not. As they're analogous to the desktop 1155
processors.

The best place to start your search for a processor, is the
motherboard manufacturer CPU support table. That will tell you
whether there is microcode support. As well as, if you read
between the lines, that table can sometimes serve as a warning
as to what processors might not have the bus connections for
a multi-socket server board.

A lot of the details for these things, aren't spelled out in print
very well. I guess you're just supposed to absorb the details
from the diagrams somehow. Here, are a few multi-socket
diagrams, giving some idea how coherent bus count on the
processor, enters into the selection. This is for bigger
systems with Xeons or Opterons and the like.

Hi Paul,

I did check the CPU support table on the motherboard's
web page and both were supported. I just couldn't figure
out the difference between the V2 and the non-v2. (I do
now.)

A tip on the E3-12xx processors. Those ending in "0"
have no GPU. Those ending in "5", do. I prefer to
add my own GPU, unless the user is hermetically cheap.
It annoys me that I have to mask off unused DVI and/or
VGA connectors on certain motherboards. I use a plastic
cap and tape it on.

My favorite GPU for a basic workstation is the EVGA
GeForce 01G-P3-2615-KR, GT 610. Around $50.00 and
works well.

Thank you for the in depth tips!
