thats like measuring a p4 running 2ghz, a G5 2ghz and a athlon running 2gh, you can't measure them p4/celeron you can as long as you measure ones with the same stuff. not all celerons are the same. wow. If you do overal performance wise like a bench mark then that can say whats better. but saying that they have different specs yea they are different.
you forgot to 845 chip sets of p4 2.8 ghz, i have a 845 3.06 now with 800 fsb its the 3.06EE. Find a 2.4 P4 Northwood 533fsb 845 chipset and a celeron 2.4 533 845 chipset. And stick the same componets in. The celeron gets a much lower bench mark. you have to measure the same things. Yes, the 910 i believe is not avaible for p4 processors, only celeron. but for the most part the celeron is the processor that didn't make the grade.
