I just installed a new motherboard with an AMD 2000+ processor. At boot up it registers the 2000+ processor, but in the BIOS and systen check it shows 1667MHz. Why is this?

    AMD is behind Intel's game in terms of raw speed (clock frequency) with their CPUs. This is due to the fact that Intel has more advanced chip die manufacturing capabilties. Intel can produce smaller micronized circuits which translates into higher clock frequencies. However, AMD's CPU design is more efficient in terms of processing information. The amount of information your 1667 MHz AMD CPU can process per clock cycle is greater than the 1667 MHz Pentium 4. The problem is that Intel is still the standard by which PC hardware is judged, and AMD knows this. AMD also knows that the general public pays attention to the megahertz frequency of a processor more than it should. AMD tested their CPU and came up with an equivalency rating against Intel's product. So according to AMD's estimation, your AMD 2000+ (1667 actual) CPU has roughly the same processing capability as a Pentium 4 2000MHz (2.0GHz). AMD feels it needs to do this so as not to get short changed when advertising its product. Any time you see a plus sign next to a processor speed, that means the number you see is an equivalency rating against Intel.
