I have a P4 2.4 Gig and my wife just got a 2.93 Gig Celeron D system with 256 megs of memory, will add another 512 Megs this weekend. For SETI The Celeron comes close to the P4, 2 and a half hours compaired to 1 Hr. and 40 Min for the P4. PREDICTOR: For Predictor it slows down a lot to about 2 to 3 Hr's compaired to 40 to 45 Min. on the P4. CPDN: I have not tried this on it, as I will be reformating the HD and installing Win XP this weekend, has Win 98 now, but I have seen some Celerons keeping up to or doing better than P4's of the same speed. After changeing the OS and adding more memory I would like to run Rosetta on it as long as it dues not take a lot longer. Will probably run 50/50 SETI and Rosetta or CPDN. Would prefer Rosetta over CPDN as there Sulpher model is taking close to 2/3 of the time on the P4. If Rosetta takes to long here I will stop SETI and run Rosetta on the P4 when the Wifes system is ready. Ray Pizza@Home Rays Place Rays place Forums ID: 1331 · Rating: 0 · rate: / Reply Quote

What you want to know about is whether or not the project's science application uses the level 2 cache in the CPU a lot or not. Because that's essentially the only difference between the CPUs: The amount of L2 cache (128KB-256KB for the Celeron against 512KB-1024KB for the P4). ID: 1344 · Rating: 0 · rate: / Reply Quote

And it seems to not need that big of an L2 cache, it is doing better than my P4, but it's clock speed it a bit faster, 2.93 gig compaired to 2.4 gig for the P4. Of course each project is diferant as to what CPU's thay run better on. Now I have to get more memory on the P4, only have 512 Megs now. The new Celeron (wifes computer) has 756 megs.
