Dear CPU Scorekeeper

I have a Dell Inspiron 7000 notebook and am thinking about upgrading the processor. My system has the following specs (PII-366, 128 MB RAM, 10 Gig HD, 8 MB video card, 2x DVD, Zip).

I know the motherboard is 66 MHz, therefore I can only go up to a PII-400 or the Celeron 466. The price range between the PII and the Celeron is about $90.

bulletAs illustrated on our CPU Comparator, the mobile Celeron-466MHz is approximately 20% faster than the mobile Pentium-II 400MHz processor.
bulletAlthough the latest mobile Celerons support Intel's latest SSE (Streaming Single-Instruction-Multiple-Data Extensions) multimedia instructions found also in the Pentium-III, the Celeron-466 upgrade option for your 66MHz bus does not.

Both the mobile Celeron-466 and the Pentium-II do support the now-standard MMX multimedia instruction set. As they are both based on the same floating-point core, there will be little essential difference in the graphics/3D capabilities between the two processors.

bulletAgain, as shown on our CPU Comparator, the mobile Celeron-466MHz is approximately 30% faster than your current PII-366. What this means is, on average, a 60-second spreadsheet calculation on your Pentium-II will take only 45-seconds with the Celeron-466.

While this may not seem especially significant, over an 8-hour working day it might mean an hour less time wasted in waiting for your computer to respond or perform basic tasks.
