seems to me like the rare e5-2686 v3 at around $500 might be considered the best one compared to e5-2673 or 2683. it's the most expensive of the 3 but you get both faster clockspeed and a lot more cores for not that much more. it is rare to find one though.

@wildpig1234 I believe it's rare because it's a specific chip for a specific retailer... kind of like the 10 Core @ 2.9Ghz w/out HT I have. (Which, they also have with HT known as the E5-2666 v3, wish I had that one!! 2.9 to 3.3.)

Why do you guys think that 2683 is most cost-effecive?
That's 14 cores @2Ghz, right?
2658 is 12 cores, and sells for twice as less.

So for same money ($300) you can get 14 cores in single chip, or 24 cores in dual-cpu system.

Where do you see 2x 2658 v3 oem/retail for $300-350? Not talking about ES... plez post a link so we can get one for that cheap :)

The core count on the 2686 is surreal. 36 independent threads makes for some serious server oomph. 2.0ghz would probably make it feel a little lazy if you were pushing desktop vms but outside of that I imagine 2 of these would make for a server with very very wide shoulders.

It's the only somewhat affordable 18 core cpu right now. everything else is still over $1k.

Why you're excluding Dual-CPU systems? May be I miss something about it? Or i'm mixing ES and non-ES again?
2 x 2658 = 24 cores/48 Threads
2x 2683 = 28 cores/56 Threads

not excluding dual core. see my original post. Just talking about the price of each cpu. 2x 2686 would be 36 cores 72 threads. seems like that's the best combination of price/cores/clocks even if it's not the cheapest v3 cpu

Probably not. I'm looking at ES/QS mostly, so won't compare ES and non-ES prices. Even looking at specs, how could 18 core @2Ghz cost less then 14 or 12 cores at same clock?
When looking at price/performance ratio, CPU with lowest cost usually wins. Can you find 8 core Xeon for half price of 2686? It will be better price/performance alerady.
2667 for example: you lose 50% of cores, but gain 60% clock. Comparing cores to clock is like apples and oranges, but anyway.

ps. and I'm really wanna hear back what others think of that.

just talking about QS and OEM price, not ES. and we are talking about current market price not intel price.

2667 v3 is fast for clock but too expensive. also looking at ebay, that part is like over $1k. at full multithread the 2686 is about 50% faster than 2667. That is why I think 2686 is probably the best one taken everything into consideration for the v3. and then next best are probably 2683 or 2673.

At $509 it's still expensive somewhat. I've heard the QS was at $399 and lower this summer. Unfortunately with our Canadian dollar even converting that $509 makes this less appealing compared to a E5-2658 V3 or similar processors.

Yes it's possible. The older LGA2011 Xeons already come in at much less than the price of a QS E5-2686 V3. For example the E5-2670, 2680, etc... are all 8 Cores and cost much less.
