I'm looking at two CPUs, a Pentium D 925 Presler and an Intel Core 2 Duo E43000. The Presler has just gone down in price, while the Core 2 is about $25 more.

The Presler is rated 3.0 G while the Core 2 is 1.8G. They seem very similar so why is the Core 2 more expensive?

The core2 architecture is just better, it isn't all about the ghz. someone on here can explain it better than i can, but i think theres a tutorial on it, so check up top in the tutorial section. The thread is like somethin about what ghz really matters, intel ghz vs AMD ghz.
here's the link The Truth About Processor Performance (a.k.a AMD GHz vs. Intel GHz)

because it processes far more efficiently than the Pentium D and does so at lower power consumption and heat output. the Core 2 Duo's are pretty much all more powerful than the Pentium D series, despite their lower frequencies.

yea, PD is pretty much 2 P4s, which aren't nearly good as a Core 2 duo. I bet a core 2 duo e4300 could outperform the PD EE edtition (it can outperform the x6800, so why not?)

You cannot compare clock speed as each architecture is different with the Core 2 Duo's being much better. The E4300 will destroy a Pentium D...especially after being overclocked to around 3.0ghz.

Pentium D's have trouble keeping up with Athlon X2's which have trouble keeping up with the Core 2 Duos....

Got the Core 2 Duo, it was only $25 more. Just wanted to be sure more expensive was better in this case.

Pros and Cons of Pentium D
Pros:
- higher clock speed
- more cache if ur looking at the e6300, e6400 and e4300 and e4400 (these two factors don't make much of an edge over c2d)
- 65 nm (but this is also in core 2 duo)

Cons:
- runs hot
- if u get a SmithField processor (not 900 series) u get 90 nm
- not as overclockable as Core2 Duo
- Netburst Architecture not favored in games
- Not as efficient as Core 2 Duo
- Power Consuming....
- The EE version is pricier than the Core 2 Duo and is wayyyyyyyy slower
- Not worth it when the higher-end 900 series are more expensive than most Core 2 Duos and not as powerful
- Can't even fight x2 processors let alone the Core 2 Duo....
