5 out of 5 eggsThe last of 1366

Pros: Seems to overclock pretty well in a consumer motherboard. My now ancient Gigabyte X58A-UD3R rev.1 (BIOS F8b) picked this right up from the i7-970 I had before.

After a month or so of tweaking, settled on a stable 4.5Ghz. This is running Rosetta@Home constantly (so 100% load, at all times). And with Hyper-Threading, 24GB memory @ 1600, 24/7 clock speed. I state that not to brag, but because some people will quote a high speed that only runs "under certain conditions."

If I had a week long rendering job, I would trust this machine to complete it.

This is compared to 4.2Ghz for the i7-970 that this chip replaced for reference. This chip just happened to be better. Not trying to promote buying xeons "just because."

My final take away is that this will likely be the chip that will be in this machine until it finally dies, I'm pretty happy with that.

At 4.5Ghz with 12 virtual (but outdated) cores, it still seems to get the job done pretty well =D

Cons: It's unfortunate that 6 core processors on socket 1366 never really became affordable before the socket was EOL. I would say price as a Con, but this is a Xeon, not an i7.

If you aren't an overclocker, or you are legitimately putting this chip into a server for production use this chip won't have a chance to really show it's strength.

Being that this architecture is roughly 2 generations old, and that the x58 chipset (Intel 55x0 I/O Hub in Xeon trim) is limited to native SATA II support and PCIe Gen2, unless the task you run on the server is especially processor dependent w/o being I/O bound, it's hard to justify the upgrade being stuck at the stock 3.2Ghz speed.

Other Thoughts: I must disclose that I "inherited" this processor from a dead server, and did not pay for it from my personal funds. That said, if you have a solid socket 1366 system you are happy with, and you were considering any 6 core (12 HT) chip, be it a xeon or Gulftown i7 as a "final upgrade" I would recommend it.

This is all price dependent, of course. When you can build a 5+Ghz 8virtual core system with better performance, obviously it's time to move on.

You won't be able to match the single core performance (or overclocking) of newer chips, but if your workload scales well over multiple cores - AND you already have an existing 1366 system that can overclock - this makes a nice upgrade.

Of course, if you're starting from scratch... this isn't the place to start.

Fun food for thought: Until Intel finally unlocks the 8th core on consumer socket 2011 chips that can be overclocked (not just the locked down xeons), you can still be competitive in distributed apps with this old tech =)

Ironically, as Sandy Bridge-E is native 8 core (16 virtual) chip, but without competition in the high end space... socket 1366 barely shuffles on.
