(IIRC, this is a 2GHz processor)
2.1GHz according to the web.
Perhaps more interesting is that yours has 64KB each of L1 instruction and data cache versus mine's 32KB each. But mine has 4GB of L2 cache versus yours only 512KB L2.
I've found it impossible to reason about the affects of caching, given the different sizes, n-way associations, and multiple levels. Bad enough with two, but now they are throwing (huge) L3 cahces into the mix as well. Not to mention hyperthreading where 1 hyperthread can utilise the core whilst the other hyperthread is waiting for a cache load.
In the end, all you can do is measure on the hardware your using and accept that it might work completely differently on another machine. Or even on the same machine with a different mix of competing processes.
