How big are the differences between a Celeron and PIII?

[Tipycol]

I was thinking about getting a Celeron 766 (66MHzx11.5) and putting it into my PIII system. I was just wondering if the differences are that great between the two that it might not be worth it. Of course I am hoping that it might actually run at 11.5x112, but I know that is very unlikely. Anyone have any advice?


Thanks

Yeah, I'd say 11.5X112 is nearly impossible. Even 100 FSB is probably asking too much. If I remember right, a P-III 800 benchmarks about the same as a Celeron 1000 (assuming the same FSB), mainly due to the difference in cache.

also the L2 cache is different.... coppermine P-iii's has 256KB of L2 and the PIII-S have 512KB of L@ and the celerons have 128kb of L2 i think all the cellys have that much not sure tho

Coppermine Celerons have 128kb L2 cache, Tualatin Celerons have 256k L2 cache.

But if you're underclocking that PIII to 560, even the non-overclocked Celeron should do about the same. So it might be worth a shot to buy one, you might see a bit of a speed increase.

This would be a nice alternative for you: http://forum.oc-forums.com/vb/showthread.php?s=&threadid=134008

Running at 112 FSB would a walk in the park for these processrs plus you need to keep in mind that they have 256k of L2 cache just like the Coppermine PIII's.

After looking at this: http://www.geocities.com/_lunchbox/cputable.html it appears that your motherboard would have a pretty good shot at working with this mod. Please LMK if you have any interest.

If u want your upgrade to be worthy you may want max Mhz without 4-divider... then you should go for Tualatin celeron 1.4Ghz (100fsb) http://www.powerleap.com or some other or mod. It may be easier to find Tualatin than old celeron.

K thanks for the help guys. I was just wondering how it would perform since they were selling on eBay for like $40. I don't know whether or not to get it still. Guess it'll depend on when the nForce 2 or KT400A boards come out.

If you're looking for an easy tight budget upgrade, why not shop around for a cheap used Celeron 900 (all of which are the good cD0 stepping). Then run it at 112 FSB for 1008 MHz. Celeron 600 can be had for $20 to $25 and will generally do 900 MHz. However, if your mobo is a slot 1 and you want real performance, find a 1.2 Tualatin and slotket, then do the Tualatin mod like Jmsandrsn posted.

Yea I am looking for a cheap upgrade but wanted to know how they'd compare. I do have slot-1 but I don't think I'm gonna spend the money on the powerleap adaptor. I was just looking for the highest multiplier that a PIII board can get, which was that celeron.
