Performance difference: Tbird 1400 (200) vs Tbird (266)????

[julks]

I'm using an A7V (not A7V133) rev 1.02, and it has only 100MHz (200MHz DDR) FSB, so, the most powerful CPU I can use on this mobo, is the Thunderbird 1400 (200MHz FSB).
What I want to know, is the performance difference between Tbird 1400 (200MHz FSB) and Tbird 1400 (266MHz FSB)... Is it a big difference??
I didn't found a review that compares the performance differences between these CPUs, anyone has a link?



Like always, thanks for your attention.

on paper, you'd get a 33% increase with the 266FSB T-Bird...but in real life, don't know how much you'd see.

That's exactly what I want to know!

33% increase in what performance?

FSB doesn't increse your processor performance. It increases memory bandwidth.

OK, and what about the real life performance?

the fsb"IS" part of the real life performance........it makes a big diffrence.........just like when you o/c a 133 system to 150.........you notice a big diffrence

 

[Insidious]

I have to disagree about the "big difference" you notice from 133 to 150 FSB....

I can measure a significant differnce, but that is really the only way I notice it



edit:

let me qualify that........ When I play FPS games, I do seem to become a little better.

but the difference between 150fps and 230 fps is not all that noticable. However, if I was

moving between say 20fps and 100fps....... that would seem huge! It's just that I think

with an Athy 1.4, you are going to be starting in a pretty good place even with no O/C

u can assume the real life performace gain is less than 33%. for most application such as office its practically 0% and the only place where u'd see a difference is in 3d intensive games and im guessing 15-20%

Are you talking about lowering the multiplier and increasing the FSB to achieve same CPU clock?

If not, this is out of quesiton. Ofcourse its going to run faster if the multiplier was kept the same and FSB was increased, because clock speed would go up as well.

1.4 (200) vs 1.4 (266). Noticeable performance increase due to increase bandwith not only to RAM but CPU to RAM.

I do want to play 3D games, but it's not the most important... So, that way, the diference between 1.4 (200) x 1.4 (266) is small, am I right?

By the way 1.4GHz 200MHz FSB Thunderbird is about $20 higher due to less supply. I'd get a 200MHz FSB 1.3GHz and save $30.

You can always put an Athlon XP in it.

yah, if he wants to underclock it

AkumaX:

But if I underclock it, maybe the performance will be on par with an Athlon 1400 (200)...
