Dual Core comparison

[Nocturne_sa]

Hi there,

planning on a major upgrade but facing a bit of confusion regarding CPU choice. I wanted to know how different are the core 2 duos from their predecessors core duos (Pentium d) apart from being 64bit. Ive got a tight budget and was hoping to go for 915 Dual Core 2.8GHz rather than the core 2 duo models...my board is the 975xbx so I can always upgrade to core 2 duos or something better in the future...
Ive heard that core 2 duos perform generally well and also run cooler than the core duos ... is that correct? Any advice will be much appreciated... my system components are ;

Intel 975xbx
Corsair XMS2 2gb Pc6400C5
His ICEQ3 X1900XT
Seagate 7200.10
ThermalTake Toughpower 650W

cheers

The new core 2 duos are much faster than the old Pentium D's.

Heres a benchmark of a Pentium D 2.8ghz against a Core 2 duo E6400. The e6400 is nearly double the speed.

cheers for the info.. so basically if i were to choose between e6300 and Pentium D 915 2.8GHz then I should go for e6300 even though the pentium d has 4 mb cache (as opposed to 2 mb on the e6300) and is clocked at 2.8?

Yes. And you can very easily clock that e6300 to 2.8 Ghz anyway

Yes, the E6300 will very easily outperform any dual core P4 available if overclocked (and they all overclock very readily). Even at stock speeds, it will outperform a Pentium D 915. Yes a 1.86 Ghz processor really can be faster than another one at 2.8 Ghz.

Just another point is that the first Core Duo's were not Pentium D's, they are an entirely different line. They were based on Pentium M's. They are mainly found in laptops and Mac's.
