What version of x86info was this?
I think the first report was from an earlier version, as it literally identified the version as 'VERSION'.
Since then I upgraded the processors. Now it shows: Found 12 identical CPUs Extended Family: 0 Extended Model: 2 Family: 6 Model: 44 Stepping: 2 Type: 0 (Original OEM) CPU Model (x86info's best guess): Core i7 (Westmere-EP) Processor name string (BIOS programmed): Intel(R) Xeon(R) CPU X5680 @ 3.33GHz
It managed to get the get closer on the model -- the Core i7 is the single-cpu version of this chip (Xeon's are a bit slower because they have circuitry to allow for multiple CPU's / motherboard).
It still isn't running any hyperthreads, and it still isn't a tricore! :-) Did intel make any tricores? I think AMD did, but not really sure.
Hope this helps (the version was gotten through SUSE's Tumbleweed branch....
How can an 8 year old processor be so misidentified by this utility?
x86info:
x86info
x86info vVERSION Found 12 identical CPUs Extended Family: 0 Extended Model: 2 Family: 6 Model: 44 Stepping: 2 Type: 0 (Original OEM) CPU Model (x86info's best guess): Unknown model. Processor name string (BIOS programmed): Intel(R) Xeon(R) CPU X5660 @ 2.80GHz
Total processor threads: 12 This system has 2 tri-core processors with hyper-threading (2 threads per core) running at an estimated 2.80GHz
The system has 2 hexacore processors with hyperthreading disabled. With hyperthreads it would have 24 threads.
lscpu shows it as:

The system is a numa machine BTW, something that should be noted to get best performance.
