ok..so ive been using a computer for quite some time now..and im still curious to know this.Why does my processor say its 2.8 GHz,but it reads 2.79 GHz?im looking for serious answers..im around so talk away

lol thanks bottom guy..your result seems to sound good in many ways :P
glad to see such enthused speaking .thanks for the information man.better than a search would give me LOL

First, advertisers estimate the clock speed based on the average of the speeds of the chips in a given manufacturing run. So 2.8 vs. 2.79 could be a simple variation because the 2.8 was an average. OR they could have lied knowing that no jury would convict them for fraud over 0.01 GHz error.
Second, as mentioned in one of the other answers, 2.8 and 2.79 are very close. Close enough that the 2.8 could be just a round-off. Because that IS what 2.79 would become when rounded.
Third, it is actually possible for computer cycle clocks to drift slightly with temperature changes if they are crystal-controlled. On a hot day you might see one speed and on a cool day you might see another.
Fourth, (and this one will probably catch you by surprise), it might be that your local POWER is off-cycle by a little bit. Long-term, local power (like, from your wall socket) is very accurately 60.00 cycles per second, to very high precision. But short-term, it can vary. The 2.79 or 2.8 can be referenced based on the time-of-day clock that depends on the accuracy of the input power line. If THAT happens to be off just a smidge, you would get the results you claimed.
So... why the difference in times between advertised and measured? Damned if I know! But I gave you enough reasons that you could pick one and be happy.

Hi,
That result you're seeing is very close to the expected value. Each processor varies in speed - even ones from the same batch.
With a value so close to the expected it could be just a difference in rounding the number.
I'd say everything is A-OK.

Mean your CPU is really only running at 2.79GHz clock speed. Theres nothing more to it. Fear not though, it's quite common, and really you havent lost anything noticeable at all

Processor speed is 'rounded off'.
