the cpu is a xeon e3-1225 v2. it's got 4 cores and 4 logical pcoessors, which is comparable to my i7 at home in terms of clock rate and cores, but the xeon is more efficient at the multi-threading. I'm able to run 6-8 char's concurrently with 1/2 of the ram and it seems to have more fluid operation. That's completely subjective mind you, so take that with a grain of salt. But at a base level I can definitely run 2 groups on this workstation at the same time without much trouble. I could probably operate a few more, but I'm nearing top end cpu/mem utilization even with eqwire and isboxer for minimal-ish eqclient's on all but 2 toons.
