Need help on cpu performace

[Guest]

Hey community. I have just upgraded my workstation, it used to have a Intel Core 2 Duo E6600 2.4Ghz cpu and now I have upgraded it to a Intel Core Pentium D 945 3.4Ghz cpu but it says that the Core 2 duo is faster in the windows index. It gets a rating of 5.9 but the Pentium gets a score of 3.4Ghz. Why? is it not as good. They came out in the same year at the same month and I can't really believe this. Should I just not listen to what windows says about this performance but I need help to find out this.

Thanks

The Pentium should be better - http://cpuboss.com/cpus/Intel-Pentium-D-945-vs-Intel-Core2-Duo-E6600

The e6600 gets 5.9, What does the Pentium get?

It gets a 3.4.

That is a P4D 945. It's an old prescott P4. The C2D is much faster. I'd put the C2D back in.

The C2D has a speed of 2.4Ghz vs. Pentium 3.4Ghz. But still why is this NOT right?

You are measuring performance based on frequency? That's like saying a dually truck should go faster then an F1 car because it has six wheels instead of just four. It's called the megahertz myth, and was debunked a long time ago.

Just no.

You downgraded substantially.

The 945 is a Pentium 4 (aka worst CPU architecture on earth) while the Core2 is conroe based.

Even with 1 GHz less clock speed the E6600 easily beats the 945 because the 945 has a long pipeline and takes many more cycles to do the same thing.

That's a lot people on this post, I better put that Core 2 Duo back in quick!
