Does a front side bus make that much of a differnece....


Perhaps I have a 900Mhz CPU, and the I see a x.xGHZ with a 800mhz Front Side bus, Regarding the initial processer speed, would the FSB act more like a seperate processer, or just a helper, and if so could an 800 FSB out perform a 900MHZ cpu?

? not sure what you are asking. A faster frontside bus means the processor can communicate with RAM faster. Right now the system bottleneck is the speed of RAM. In the last 5 years cpu speeds have gone from 300mhz to 3ghz, but RAM speed has only bumped from 100mhz to 200mhz. As you can see cpu speed has really out distanced RAM speed. So now these fast cpus are sitting around, waiting for data from the RAM. A faster FSB helps move that data faster.

What I mean is, Could the Front Side bus Alone Outperform a CPU of similar speed......oh lets say a 555MHZ FSb...Could a 500 mhz processer be similar in performance.

The FSB does no processing, it cannot "outperform" the processor, it's simply the amount of information that can go from the processor to something else. It's like a pipeline letting water through. A bigger pipe will let out more water from the pump, but without the pump itself, the pipe will do nothing...

so to answer your question, yes, a faster fsb with a similar processor will be faster. Say you have a 2.5ghz P4, one on a 533fsb, the other on a 800fsb. The 800 will be faster as it won't be waiting as much for the ram

Yah, but his question was if the FSB alone, not coupled with a processor, can outperform a processor. That's what I get when I read it at least.

And thats what Im asking..Is a FSB a processer in it self, because I see MHZ and I think processer.


Just curious because Im getting a new computer soon and wondering if a FSB helps much

Ok, I already explained it.

You're getting these fancy key terms all mixed up. People like to throw around "MHz" because now all the lamens out there know (think) that higher MHz = better, but it's just a measure, a number, actually. A Hz is short for Hertz, which is just one time, or cycle, per second. And the Mega suffix is just a suffix for a million. So a processor at and Giga means billion. So a processor at 2 GHz runs at 2 billion cycles per second.

The MHz attributed to the FSB is just how much per second can be put through.

Nevermind, the answer is no.
