Hello!!!

Pentium4 550 = 200MHz x 17.0 = 3400MHz
Athlon64 3500 = 200MHz x 11.0 = 2200MHz


Above mentioned lines in CPU101 section but i didnt understand from where these 200, 17 n 11 numbers came, can anyone throw light on this?

Thanks,
Prasad

17 and 11 are the multipliers.

p_shinde

then 200 is it a general number used for pentium 4 processor? but then they also used it for Athlon processor?

[-0MEGA-]

With the Pentium 4, the 200Mhz is the speed that the FSB runs at, and 17 is the multiplier for the 550 model. The multiplier is either raised or lowered depending on the P4 model.

The Athlon 64 is similar, however they dont have an FSB, they use Hyper Transport Link (HT), so for the A64 it's 200Mhz HT x the multiplier, in this case 11.

As an example, the current Core 2 Duo's would be 266Mhz x 8 = 2128Mhz (2.13Ghz, AKA E6400).
