I'm a newb when it comes to PCs so forgive me if I make any mistakes or have any misconceptions.
From my understanding:
CPU clock speed = real FSB x Multiplier
However, the 'FSB' on an AMD is actually an HTT, which has the same effect but works differently (I'd appreciate a little bit of information regarding how they function, AFAIK, FSB speed is the speed at which CPU can send data to and from the other components, so how does HTT differ? Although this is very welcome its not the main point of my post.)
1. On Athlons the HTT is dual pumped to give an effective speed, however is it quad-pumped on Athlon 64s? The above equation would only work if they were quad-pumped I believe.
2. Is the reason an Athlon 64 is considered superior to the equivalent Pentium IV (esp. for gaming) due to the higher FSB as opposed to the higher multipliers as seen on Pentium chips?
3. Core 2 Duos are still quad-pumped but they are seen as more efficient than Athlon X2's (which have been pumped 5 times to my understanding) and Athlon 64's which are also pumped 4 times. Is this because the FSB is higher than the HTT of Athlon X2's, and they are dual-core and therefore superior to the single-core Athlon 64's?
4. Are the multipliers on C2Ds locked, or does the FSB have to be manually adjusted when OC'ing?
I realise I'm asking a lot, but I'd really appreciate any help I can get on even one of these questions, thanks very much.
