Could we get #'s w/o overclocking? I mean, I can get reseller/bulk deals on things like 2x L5639, but they won't be overclockable (so 2.13ghz)... so I still can't tell if they're worth paying $50/mo for... since even on a Google search just about everything I see is some value w/ an overclocked machine.
For the record (all on Ubuntu 13.10 unless specified otherwise),
E3-1270v1 @ 3.4ghz, ~350 collisions/m, using 8 threads @ 1GB mem.
E3-1230v1 @ 3.2ghz, ~335 collisions/m, 8 threads @ 512kb and 7 threads @ 1gb have essentially this same value. These servers only have 8GB of RAM, so I can't run 8 threads @ 1GB.
Dual Xeon L5420 @ 2.5 ghz, something horrible, 8 threads @ 1gb, use for some minerd quark algo thing
Dual Xeon L5520 @ 2.27ghz, ~405 collisions/m, 16 threads @ 512kb mem
Dual Xeon L5639 @ 2.13ghz, ~535 collisions/m, 24 threads @ 512kb mem (using numactl)
Dual Xeon X5650 @ 2.67ghz, Windows 2008 R2 Enterprise, 640 collisions/m, 24 threads @ 1GB (havent really attempted to optimize)
Dual Xeon X5650 @ 2.67ghz, ~685 collisions/m, 24 threads @ 1GB (using numactl)
i7-4770 @ 3.4ghz, 407 collisions/m, 4 threads @ 1GB
i7-4770 @ 3.4ghz, ~720 collisions/m, 8 threads @ 1gb (using all 8 *threads slows the integrated GPU down from about 20-25 khash scrypt to 10 or so)
Xeon E3-1240v3 @ 3.4ghz, ~690 collisions/m, 8 threads @ 1gb
