Enty level is really nice considering the price per core:

Intel Xeon E5-2630 v4 10/20 2.2 GHz 25 MB 85W $667 US

Intel Xeon E5-2630L v4 10/20 1.8 GHz 25 MB 55W $612 US

Intel Xeon E5-2623 V4 4/8 2.6 GHz 5 MB 85W $444 US

Intel Xeon E5-2620 v4 8/16 2.1 GHz 20 MB 85W $417 US

Intel Xeon E5-2609 V4 8/8 1.7 GHz 20 MB 85W $306 US

Intel Xeon E5-2603 v4 6/6 1.7 GHz 10 MB 85W $213 US

Nice. :)

A better calculation would be per GHz-core. Because a core at 2.2 is not the same thing as a core at 1.7.

In all honesty, cache should be in here too. Getting a daxpy to fit into cache is the most satisfying feeling in the world.

Don't forget the rest of the machine. At these comparatively low CPU price points, buying three machines instead of two might not be a good decision.

(Of course, licensees of per-core-licensed software are screwed again.)

except, open source :-)

Compared to the 5820K i7, these don't seem much better... Is there something I'm missing?

ECC ram and multi-processor support. But yeah I see what you're saying and I agree.

ECC isn't just a gimmick nowadays?

Huh? ECC is necessary for anything but toy applications.

Is it? Or is that the old wives tale? Many very non-toy applications started on consumer hardware (including Google, and they turned out alright).

You'll note that Google grew ECC as soon as they started billing people for real money. This is no coincidence.

The Xeons support much more RAM.

They all seem to be an extremely incremental (to be kind) iteration on what was already out there as far as price goes. I have no idea why there are so many people that seem excited by them. The chips might be good, but the prices negate any of the gains.

There is no way Intel would be charging over $4000.00 for a chip if they had any competition in that space.

Ah yes but we would need to see how much faster is a 8/16 compared to a 8/8 and I bet that'd be workload dependent...
