<< So do you notice any speed difference? The tualatin celeron is faster right? >>
I haven't had them long enough. I got the P3 to extend the life of my BX chipset system. The specs of the systems are totally different, and thus I cannot make a comparison for performance. However, I _can_ say that the Celeron runs much cooler, making for a very quiet system. Here are the specs:
P3 1000/100@1300
Abit BX133-RAID mobo
256MB CL2
dual 7200RPM drives, RAID-0
etc.
Celeron 1.0A@1333
Abit VH6-T mobo
512MB CL3
single 5400RPM drive
etc.
<< Without overclocking, the Coppermine P3 would be faster. Tom's Hardware...
But if you're not overclocking, the Tom's Hardware review above includes another processor you should think about; the Tualatin P3 1.13Ghz. With Intel's price cuts late January, they're getting a bit more reasonably priced. Pricewatch.com has the retail P3 1.13Ghz at around $160usd >>
Yes, the P3 did better in many benchmarks. I think the big difference is FSB speed. At the same speeds, the Tualatin P3 would be faster than the Coppermine P3, right? Has anyone done such a comparison using identical equipment with a Coppermine 1000/133 and a Tualatin 1000/133? There is an overlap at that speed, as well as 1133. There is also a 512k cache version of the Tualatin, but it seems intentionally priced above faster products such as the Northwood 1.6A and 1.8A chips.
<< The Tually Celeron has data prefetch which will give it the edge over a PIII at the same clockspeed/FSB. >>
I think that is the key. Reading up on the specs of the Tualatin versions of the P3 and Celeron, except for the 512k cache version of the P3, they both have 256k 8-way set associative cache, .13 micron process, data prefetch.... are there any differences whatsoever? Well, FSB is one, plus I've heard somewhere that Intel put a cache latency on the Celeron. However, increase the FSB to 133 on the Celeron and reduce the cache latency (some boards let you do this) and the two chips ARE INDEED IDENTICAL. Since the Tualatin P3 is faster than the Coppermine P3, this would make the overclocked/tweaked Tualatin Celeron faster than a similar speed/FSB Coppermine P3. Of course, you can start with a 133FSB P3 (Coppermine or Tualatin) and overclock to a higher FSB, but you risk potential problems due to non-standard FSB speeds.
BACK TO the original question by drx9175l... my belief is that he should get a Celeron 1.0A and overclock it. I have that CPU on the same mobo he has, and it is an easy OC, even with the retail-box HSF. With a 1.0A@1333, the P3 loses it's FSB advantage. Also, compared to a P3 Coppermine running at default speeds, the Celeron at 1333 runs cooler. Here are other reasons for my recommendation:
-Celeron 1.0A is $77 versus $140-160 for P3 1000 whether Coppermine or Tualatin
-Celeron is pretty much an easy OC to 1333, some have gotten over 1400
-Coppermine P3 gets REALLY REALLY hot overclocked to 1200-1300, and may or may not be stable
-Tualatin P3 probably OCs as easy as Celeron, but you risk various FSB probs
-Socket 370 doesn't have as much of a future as other interfaces, so he probably should waste as much on it
