That is it. I have a Xp2000, and it runs at about 1600Mhz.
Gone are the days when the CPU number meant it's speed, A 486Dx66 ran at 66Mhz. These days the number is just that, a number, with no bearing on the actual speed of the CPU. It just means a XP2600 it faster than a XP2000 at doing benchmark tests. by about 2600/2000 or 1.3 times (very roughly) as 2000 times 1.3 is 2600.
Think, the VW golf MK5 was not five times faster that the VW golf MK1.
could I just ask in thread about ram I posted another thread but didnt have any response to it I have 512 ddr 400 in new machine and I also have another 512 which is only 266fsb is it actually possable to run them both together?
No bartons are Superior versions of the thourghbred. Clock speed is not everything and though they run slightly slower they have 512K of cache instead of the 256K. This and the higher fsb, 166, makes the slower barton faster than the 2.13 ghz thourghbred.
