FSB confusion???

Can someone please explain something to me? I did a search in the forum and couldn't find my answer. So here I go...

I have been looking to get a new computer. I've always used AMD. I do lite gaming and big into audio/video, DVD's, recording from external sources.

I am confused over FSB. AMD processors usually have a FSB of 2000.
Pentium are usually 800. To my understanding, this is the speed between the Processor and Memory.

Now would a Pentium of let's say a speed of 2.4 ghz with FSB 800
run slower then an AMD of 2.4 ghz with FSB 2000?

I'm still learning alot. So please bare with me. I want the speed, however with audio/video playback and recording, I want perfection. Any thoughts? (I hope I provided enough info).

Your AMD FSB 2000 is wrong it must be 200 they are no 2000 FSB

THe latest to come from intell is FSB 1333 in that it's in a few months....

 

Really? hmmm, now I'm really confused. When I was checking out computers on Best Buy, this is what was listed...

Processor Brand AMD Athlon 64
Processor Speed 2.2GHz
System Bus 2000MHz

This is listed on most of their AMD systems.

 

You can't just rely on FSB to work out which CPU is faster.

And you need to keep in mind that newer processors are double-pumped or quad-pumped.

For example, the Intel is not 800Mhz, but 200Mhz quad-pumped etc.

Also, AMD processors are not named according to the core speed of the processor.

They are named according to how that particular processor matches against an Intel P4 processor.

For example, an AMD 3200+ only has a 2.2 GHz core speed, yet it performs the same as or better than an Intel 3.2 GHz processor.

 

the amd 64 has no fsb because it has HTT hyper-transport. The bus speed is 200mhz, but the htt is 1000mhz + DDR=2000mhz

DDR= transfers both ways at once

 

Every CPU has a fsb of sorts.

Hypertransport is merely a new bus technology.

Edit: Only dual core cpus have a htt bus that runs at 2000 MT/s.


Single core AMD 64s run at 1600 MT/s.

 

I give up. AMD has conflicting documents. Needless to say, not all AMD 64s are 2000 MT/s.

 

Ok, got it. Socket 754 AMD 64s run at 1600 MT/s, while Socket 939 ones run at 2000 MT/s.

 

Go to the OverClocking Forum and read the top post it will begin to explain it for you.

There is the FSB X Multiplier = CPU Processing speed. AMD and Intel achieve this in different ways. But even if you have a P4 3.0Ghz and AMD @ 2.6GHz may actually be quicker. I will only confuse you so go to the OC forum.

Look at image below to get a vague depiction Multiplier X FSB = Core Speed

 

well my 3700+ sandy has a HTT of 1000 and transfers data both ways =2000
