Difference from Real Hardware
While the processor device is a faithful simulation of the software-visible portion of an
AMD microprocessor, it is not a model of the specific AMD microprocessor hardware.
Because of this, the processor device is not equivalent in certain areas. Any issues related
to timing, such as the time to execute a given instruction, will be different. The TLB
models do not exactly match any particular processor, so any software that depends on
exact TLB walking behaviors may not function correctly.
