Intel® Celeron® Question

Posted:
in Genius Bar edited January 2014
if a PC has an Intel® Celeron® D Processor 320 2.40GHz



is the real speed closer to 1.2Ghz..... dont you divide by two?



Like a Intel® Pentium® 4 at the same "speed" would be alot faster...right? All part of the "Ghz game" ?

    Not sure what it compares to on a P4... here's some charts against other Celerons and Athlon XP processors:

    MHz is NOT a measure of speed. It is only a measure of how fast the clock on the processor goes. Different processors process differing amounts of data per clock cycle, and it only gets more complicated after that. The Celeron is basically the same core as a Pentium 4, but with less onboard cache, and I think they removed one of the floating point units... The new P4's now have a couple of more tricks up their sleeves... so even that is not accurate anymore. P4 and Celeron are marketing families... not processor families.



    You have to be very careful when comparing any two processors, because there are so many different factors that can affect the outcome. One processor may perform well on one test, but poorly on another.

    My advice would be to simply not buy a Celeron. They used to have smaller caches than the comparable Pentium 3/4 CPU. They also have a slower bus speed than the P4.

    The rellative speed of Celerons above 2 GHz is very application depenent

    has many tests and in Office applications the Celeron holds up quite well but in anyhing that tax the fpu like quake it gets stomped by the P4 and crushed by the AMDs.



    Back in the sub GHz range the cache less Celeron did not fare too bad compared to the pentium but with clock speed well above 1 GHz the caches really become important

    For the small price difference, it's simply not worth it.
