Hello there. Those 2 processors mentioned in the subject of this thread are of my cousin.
He got them by some exchange for something, not really important now.
I have a question about them. Which one is better ?
When I ask better, I mean for performance.. Working on PC with it ( He is normal user, nothing special or heavy to work, also he is a gamer. )
Will the Pentium D beat Celeron Dual Core because of more catche ? 4 MB vs 1 MB..
Performance is important! By the way, checked rating at System Information at Windows 7.
However, Windows 7 is giving 5.1 CPU rating to Pentium D, meanwhile 5.3 is for Celeron.
Hope to hear your opinions guys! Thanks in advance, TheBlaze.

The pentium will definately beat the Celeron, the speed difference is considerable. Performance wise, this pentium is better. Windows ratings are largly inaccurate many a times, don't consider that.
