It's certainly not the latest and greatest, 
CPU: Intel(R) Core(TM)2 Duo CPU     T7250  @ 2.00GHz (1995.04-MHz K8-class CPU)

ada0: Serial Number 1B0607771A0800257271
ada0: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes)

but this laptop has built FreeBSD for several years and each

buildworld is essentially the only thing running on it.
