I thought Xeon was a company.

xeon is usually used for servers, but Core 2s can also be used for servers.

Xeons are geared more towards server processing, meaning gaming performance is considerably bad compared to similar Core 2s. Xeons also have better reliability, as in working for 24 hours for longer than Core 2s.

Xeon is for servers, they can be pushed for a really long time.

Xeon = Packet Transfers.
Core 2 = Local Rastering. |

uh no. x86 is x86, do you think servers magically run some completely different form of code?
Any modern Xeon is likely the exact same core as a Core2, maybe minor differences at best. They simply are more "rigorously tested".
Gaming performance is going to be exactly the same as ones Core2 counterpart.
Nothing's stopping you from running a Core2 for years straight, if you have sufficient cooling, there will likely be no problems at all. |

| It's not about overheating, Core2 is known to mishandle queues.. |

Seeing as Core 2 Quads cost a good amount less than Xeons, im going to go with Core 2 for my server

While this thread is a bit old, I would like to add a bit more on the what's the difference between Core 2 and Xeons.
There are 2 types of Xeons: Desktop and Server based.
The Desktop base uses the same socket as the Core 2 which is LGA775 (SocketT) and what slovach had mentioned is correct. The desktop based Xeon is nothing more than a rebranded Core 2 that went through a stricter testing than the Core 2 and if they pass their earn their "Xeon" name. The other thing about Xeons according to what other said on the web is they are better overclockers where users can get the same desire overclock speed at a lower voltage setting than a regular Core 2.
The other difference between a desktop Xeon and the Core 2 is the Xeon has 2 additional features: Intel I/O Acceleration Technology (I/OAT) and
Demand Based Switching (DBS). I/OAT is mostly use in the Server environment so we may never see that on the home desktop segment.
According to wikipedia Intel Based Switching is just a remarketing name for Intel SpeedStep, but according to the sSpec for a desktop based Xeon
DBS is a added feature with Intel Speed Step. So I'm not quite sure as to what's the deal here.
Now the server based Xeons which is totally different than the desktop based Xeon is they can support multi-cpu.
Note: Multi-cpu has nothing to do with the number of cores in a physical cpu. e.g. If you have a 32 core processor it's still consider as 1 physical processor.
Most server based xeon runs on the LGA771 (socket J) platform and what they can do while the desktop based can't is you're allow to install up to 2 physical cpus because most of the time server boards provide up to 2 physical sockets, while other may even supply up to 4 physical sockets.
Intel SkullTrial for example uses a pair of Core 2 Extremes QX9775 in a LGA771 configuration. This let buyers setup a 8 core system where you can install up to 2 physical quad core cpus.
AMD did the same with their extreme high-end gaming platform dubbed the 4x4 (now scrapped off), where it has 2 Opteron cpus running on a dual socket motherboard.
And lastly while the rebranded Xeon is just a regular Core 2 that does not mean a motherboard that can support a regular Core 2 will also support a Xeon because the Xeons has a different micro-code.
e.g. Intel Xeon X3350 and Intel Core 2 Quad Q9450 are both the same cpus in terms of speed and specs and some features, but not all motherboard that can support a Q9450 will also support a Xeon X3350
So for those who want a Xeon based cpu make sure you check out forums and see which person has it before you put your money on it
and don't expect to "spend a Xeon cpu with a cheap $50 board".
Crap! Since I'm new here I can't post URLs so for those interested on the differences on the Q9450 and X3350 just visit the Intel processor section page and click on the "processor Spec finder tool" link. |
