AMD HT VS Intel FSB

post #1 of 12
Thread Starter 
Alright, I use to have this straight, but since C2D came out, I'm not sure anymore.

So, AMD says it's HT is 1000 mhz. Does that mean they use 200 HT 5x?

And Intel C2D says FSB is at 1066. What FSB are they using and with what multiplier?

Just need a bit of straightening out so things can make sense again, thanks!

Also, what RAM speed work's best with Intel right now? For their C2D line to run 1:1.

You got AMD right, Hypertransport is 1000mhz =5*200fsb, or 4*250fsb, or 3* 251+fsb, etc....
Cant confirm Intels as I haven't had one of the newer ones since Northwood/Prescott models.

Dont forget that AMD is double clocked to an effective 2000mhz (so 200 x 5 = 1000mhz x 2 = 2000 mhz effective) due to its unique architecture. You have to lower the multiplyer in many OC rigs because of unstability beyond 2000mhz (hence 250 x 4 = 1000mhz). If you could pull it off a system theoreticlly could surpase this by keeping the multiplyer higher. For instance an OC set @ 300mhz x 5HT = 1500mhz x2 = 3000mhz effective FSB!!!

As stated above, I also do not know how Intel gets their 1066 FSB, nor do I know if its effectivly doubled like AMD's...though my guess is not.

1066 is a quad pumped bus, not sure what the read FSB is or anything

Intel still use the quad pumped fsb so it would be 266x4 to get the 1066 then the cpu multi say at x9 then the actual clock speed would be 266 x9 to give 2300 or whatever it is

frostbites right the fsb is 266 to run 1:1 at stock you need ddr2-533 but to overclock in 1:1 i recommend some ddr2-800 which will take you all the way to a fsb of 400

Sort of. AMD does not use FSB anymore, in a way. It's just an old habit people have of calling it that.
