HPET (High-Precision Event Timer) basically increases the resolution of event timing. Think of having a log for every event that happens.
Without HPET, you're log might look like this: <Event> @ <Hours>:<Minutes>:<Seconds> With HPET, you're log might look like this: <Event> @ <Hours>:<Minutes>:<Seconds>:<Milliseconds> The big change with HPET is on your kernel's timer. The change on the processor itself is minimal. You need Vista/Server 2K8 or later to use HPET. You need a CPU that supports it. Both AMD and Intel have CPUs that support HPET. AMD's implementation (or that of the AMD motherboards') has been buggy for consumer-level hardware. I do not know if their server hardware is any better, but it probably is. You need a motherboard that supports it. Almost all modern motherboards will if they're compatible with a processor that has it. Of course, all of this is completely unnecessary.
