importance of L2 cache
I have a celeron 566 that'll run all day at 133FSB and at normal
voltage. that's 1.13ghz. (Actually it'll do 140FSB 1.189Ghz) So it's just like a PIII or a Tualatin Celeron except for the L2 cache. How much difference does there have to be in cpu Mhz to make a substitution (this chip for a PIII) worth it considering the difference in L2 cache? Does it depend on the application? eric |

In alt.comp.periphs.mainboard.asus, ordered an army of hamsters to type:

Does it depend on the application? eric If you had two cpu's running at exactly the same speed and one had more L" cache than the other then that one will have a performance advantage in more applications than the other. If you are not able to upgrade the whole mobo cpu and ram and can find a P3 for a reasonably cheap price then it might actually be worth the change of cpu. However, it may be a better use of your money saving for more of an upgrade than just a cpu. Particularly with the recent introduction of new Intel chipsets brining down the prices of some of the faster equipment than you have. Of course then you'd have the opportunity to change to AMD aswell then. I recommend thinking about it, do some research on newer chipsets and motherboards (they dont necessarilly have to be the most recent) and see what the prices are like. It is worth considering. love Kokoro |

There very existence of an L2 cache is denial of the use of the word
Celeron. So, what's a Tualatin Celeron? wrote in message ... I have a celeron 566 that'll run all day at 133FSB and at normal voltage. that's 1.13ghz.

That's very impressive, since I used to have a 566 and
it just would not go over 707 no matter what. I'm now running a 1GHz cu Celeron II at 1.12 - Got a BX chipset here on a Abit BH6, using a slotket. I suspect x2 L2 alone is not worth the upgrade, probably no more than %10 or %15 boost. The only PIII worth considering is of the 512k variety, running 1.26 or better, which your motherboard may not support, and it's still relatively expensive and hard to find. I'm not going to bother, since I seriously doubt it's compatibility with my BX chipset. Next stop, a new Celeron D system, which looks very promising at the D0 stepping that started shipping in early July. wrote in message ...

I have 4 of them and 3 of the 4 will do 133FSB at stock voltage. Ionce read about a cD0 1 GHz PIII which would run happily at its nominal clock with just 1.35 V core.) Coppermine Celeron: 128K L2 4-way associative (like Mendocino). Coppermine PIII/Tualatin Celeron: 256K L2 8-way associative, faster. Tualatin PIII: Same as above, but with hardware prefetch added. PIII-S: Same as above, but with 512K L2 and prefetch. In benchmarks, the 850 MHz CuMine Celeron was found to be about equal to a 700 MHz CuMine PIII, so your 1.13 GHz variant would be about as fast as a PIII-933. Of course, the exact relationship would depend on the specific application. Something that strictly scales with core clocks and needs little cache access, like MP3 encoding, would be just as fast as on a 1.13 GHz PIII-S. In Q3A (which loves fast caches and high memory bandwidth) it would apparently be about on par with an 800EB. If you'd like a Celeron that's a whole lot faster when overclocked, try a Tualatin 900A or 1.0A (many, if not most 1.0As will run happily at 1.33 GHz). thanks for the information, Stephen. eric |
