Saw this on ebay this morning. Five units $150 each or best offer.

They look like scratched ES chips, but if they work, might be very interesting.

This is definitely interesting. Its now 2, nearly 3, generations old. 60W is great, but i care more about idle power and I think sandy bridge+ idles much lower. It's not the perfect chip for me, but the price makes it tempting.

Well there are a few factors there. This is still a 32nm chip. Unlike an E3 series, you get a ton more addressable memory and more sockets. Performance wise, the E3 series is going to be better in most applications. Price wise, this is going to be hard to beat though.

Got 2x @ $125 each. Figure 32nm idles a bit lower than 45nm and same 60w max TDP as the L5540's.

Yeah, but sandy bridge really slashed idle power compared to previous designs:

The performance is between a E3-1220 V2 and E3-1230 V2. These cost just over $200. They have way lower power usage though (not just the processor, the motherboard too). If i save 40 watts, that is about $50 a year to me, which means ~1.5 years to justify the newer part.

I'm gonna pass myself, but for someone who cares less about idle power these are an awesome deal.

Spartus very true. The two major considerations are that those tests were done on a dual CPU system that had more RAM modules installed dual IOH and etc. You can certainly cut down power from that 2P configuration, especially if you were going single CPU.

dba - Yea not bad at all! Or that dual 40gbps infiniband one... Big question/ hope is that I find a system where they work.

what's the deal with ES - are they unstable or buggy?

You can get E5620's on ebay for $175 - non ES, just look.

Also be VERY VERY careful. Some folks out there are selling fakes. I'm not going into how they microcode patch them but look real close at any chip with CPU-ID and bench it proper.

Last pair of e5620 i got for $175 (two matching) was from OWC of all places. Pulled from am 2010 MAC PRO, well taken care of, and a very ethical reseller.

Engineering samples are borderline on ethics/illegal.

You will get your arse handed to you as a VAR for selling them, or not returning them to Intel. So while probably not illegal, there is some ethical rules being broken here. in this neck of the woods, posession is 9/10th's of the law.

The e5620's are 4 core while these which are 6 core. Probably not good to use ES.
