P-III 700 Mhz or Cerlon 900 Mhz

[Mothman]

Which would be faster for a Third computer. Same board and memory. Same everything.....Thanks

[gamefoo21]

oc'd or not?

Stock the Cele 900 would be faster since I believe the p3 is using a 100fsb.

Overclocked... If the p3 is using a 100fsb you can probably push it up to 133 with success the cele 900 hitting 133 is much less likely.

Go with the P3 700mhz. A Celeron is a budget chip and in my opinion do not perform as well as there P3 brothers.

[Mothman]

It wouldn't be overclocked, I'm putting this computer together out of spare parts laying around. I was thinking the P-III has 512kb cache and the Cerlon has 128kb......Still a guess i'am to lazy to put it together and bench mark them......:)

[funnyperson1]

I woudl go with the PIII. Both are 100mhz fsb btw.

[gamefoo21]

Its a Celeron! and the 200mhz core speed makes up for the difference in cache plus some. and the p3 if its a s370 only has 256kb. and if its a slot that 512 is running half speed. remember back in the celeron 1 vs p2 days it was only a 3% perf diff at the same clock!

If seti is big, then get the p3, if its everything else the Cele will do better. Even Sandra says that the Cele will do more number crunching.

I don't have very much experiece with benchmarking the computers you're talking about, but the cache can make a huge difference. I'd eaisly spot the p3 100MHz, but I'm not sure about 200 MHz. Try to find a benchmark that simulates what the computer will be used for and try it both ways.

That's not a really good comparison. The Celeron A was about as fast as the P2 since although it had 128kb cache, it was on-die and ran at full speed versus the P2's half-speed cache. Since then, intel has made more substantial efforts to cripple the celeron.

The ORIGINAL celeron, by the way, the one without any L2 cache at all, performed very, very, very poorly.

[dustybyrd]

there are several references to the l2 cache on the p3 chips...

p3's had either 512kb (half speed unless tualatins) or 256kb (full speed)...

the full speed 256kb cache started on the 550e's and all 600's and faster had full speed 256kb cache...

i believe that celeron 900 has 128kb full speed cache...and NOT 200 fsb anything...

both are 100mhz chips...

i believe the p3 700 is about equilivent to a celeron 950-1000 in most benchies...if it's a slot 1 board...then those p3's are very expensive compared to their socket 370 counterparts...just in case you still have to buy the cpu...

Seemed like the benchmarks I remember from that Coppermine era was that at default speed, a Celeron would have to be somewhere from 150 to 200 MHz faster clock speed to equal a P-III. This is because the Celeron has 1/2 the cache compared to the P-III. So, in the case of P-III 700 vs. Celeron 900, then it's a toss up for performance. Without overclocking, 900 sounds meaner than 700, but the P-III might be worth a tad more for resale value. Six of one and half dozen of the other.

I have had several P3's and Celerons (all FC-PGA's). The P3 never was much faster than the Celeron. In some games you could see a difference, but you won't see a big difference in general.

I'd say use the celeron, and sell the p3 on ebay. you could probably get $50+ for it.

I had both, a Celeron 600 @ 900 (Identical to a Celly 900) and a P3 700E. The P3 constantly beat the Celeron in nearly all real-world applications but synthetic benchmarks slightly favoured the Celeron.

What you have to remember with the Celeron is its cache associativity is only 4-way compared to the P3's 8-way, meaning the gap in performance is huge.

This also applies to current P4 Celeron's compared to the P4. It is this loss of associativity and NOT the less cache which affects things as much as it does. This is why The Northwood was around 5-15% faster than the p4 in games when the cache was doubled, but the Celeron is almost 30-50% slower than the willy at equal clocks.

Theres also the fact that even a mild overclock on the P3 (say 112MHz FSB for 784MHz) would put the P3 ahead in everything without a doubt. The P3 700E I had was cB0 and it did 1050MHz, even the cA2 steppings reached 800-850MHz, whereas most of the cC0s hit 1GHz+. The Celeron 900 is cD0, and should reach around 1200MHz, but will still not perform well.
