Difference between the C2D and the pentuim dual cores?

[MrIceCremeLollipop]

I wasnt into pc building/hardware when the Core 2 series was around, But looking now it seems that many of these processors have Pentium equivalent, That seem to perform identically, Such as the Core 2 duo E4700 and the Pentium e5200. Can someone explain why?

IIRC, the Pentium dual-cores had less cache and...well...that was about it. Some of those E-series Pentiums were monstrous overclockers back in the day. Looking at you, E5300 and E5800.

Were they cheaper? Why even bother releasing the pentuim/Core 2 duo if there practially the same thing?

They were cheaper. The Conroe era is when the Pentium name went from being the best of the best to being regarded as a mid-tier or entry-level CPU.

Market segmentation, Core 2 Quad is the high end, Core 2 Duo is the mainstream, and Pentiums are the budget.

They can call it celeron, but at that time celeron has a bad reputation for being underperformer while Pentium brand name still have values.
