66/133/266???

In all these motherboard reviews and benchmarks I read they all state something this this affect 66/133/266 (not necessarily those numbers) or something to that effect. I know this has something to do with the speed. Can someone please enlighten me in layman's terms? I think I've determined it has something to do with the front side bus, but I don't really know. Also, how does CPU core voltage affect things? Thanks.
 
Oh boy. That's a lot to ask. You're right, those are FSB speeds. 66 = Celeron 133 = P-III & Xeon 266 = Athlon C & AthlonXP. I'm not going to sit and explain the science of this with the resturant analogy, because I just can't push myself to type that much. In a nutshell, the more the better. If you were looking at benchmarks, you should have noticed that. The Vcore voltage is something you probably don't need to know how to adjust. Let me put it this way, it provides the power to the CPU, and more can make it run faster. Oh yeah, that's sound good. At least until you have to replace the CPU.

Well, AkumaBao is generally right in what he said, though the comment about "the more the better" is not exactly true. The Pentium 4 has a FSB of 400mhz, but it is still outpreformed by the 266FSB that the athlon has. The P4 will get faster CPU-Chipset-Ram transfer rates due to the fact that the RDRAM also runs at 400mhz (unless you are using the DDR P4 setup) however, the 266 FSB athlon and DDR will still get higher preformance on most real-world applications.

The 133mhz could also be referring to the actual FSB that the atlon-c and athlonXP run at. They double the FSB to reach the 266 mark somehow (don't ask me, I am still trying to figure that out 🙂 ) Anyway, hope that helped

P.S. I did not mean any offense to AkumaBao, I was just worried that if someone asks what 66/133/266 means, they may not have the strongest grasp on the whole FSB idea and saying more is better may confuse them 😉
 
Thanks for the answers. I was just reading through some things and realized I didn't know what they meant. I knew the answer would probably go over my head; I think I just need to read about many of these things.
