Definitely Core 2 coz it's 64-bit processor... Core Duo is 32-bit only from what I understand.


EDIT: err... think you should change the title.. it's a bit misleading when you later ask which of the two : Pentium D and Core 2 is better.

all the dual core cpus are 64bit amd and intel

all the dual core cpus are 64bit amd and intel

nope, you're wrong.
Core Duo is based on the Yonah core which doesn't support EM64T, whereas Core 2 Duo is based on Merom core which supports EM64T.

thirded fourthed... ( made those last two words up, they are mine now)

I need to upgrade my computers again ready for Windows Vista, I went to my main supplier which I have been using from day one and could not understand why these processors are so dam cheap. not that I am complaining, I am over the moon with the price, but are they more powerful than a P4 with HT Technology. (I just asked to stupid question).

These are the prices of my processor I paid 4 years ago, when I last upgraded. Which of the following processors is better... D 930 3Ghz or which is 800 FSB or the 1.86 with a whopping 1066 MHz FSB.

Processor - 1 x Intel Pentium D 930 3 GHz ( 800 MHz ) Dual-Core - LGA775 Socket - L2 4 MB ( 2 x 2 MB ) link below.

Or this one

Core 2 Duo E6300 1.86GHz LGA775 FSB1066 2Mb link below.

Which one would you get...?

Motherboard I don't have an issue with because there is only one make I will use and that is Gigabyte.

Ehm, they should not be patented. A patent applies to an idea or invention that can be physically described in algorithms.

If I remember correctly, what you want to do is get it copyrighted and trademarked.

Get the Core2Duo. The netburst technology (Basically pentium 4 - pentium D) is all faded out. What happened with the Netburst is that it wasn't efficient, even at like 5ghz, it was still waiting for something somewhere which is why they are so "slow". If you don't know how a CPU works, basically the cpu is just processing instructions in the form of 1's and 0's (transistors only have 2 settings, on and off). So what happens is the Netburst technology (pentium D in this case I think) would process an instruction SUPER FAST, but then it'd have to wait for another one because of an inefficiency in the architecture. So that's basically why the coreduo and core2duo are so much faster, they removed that inefficiency and stopped caring about maximum obtainable speed. Then netburst technology, in theory could reach like 10-20ghz I think it was, but that's beyond the thermal limits of silicon, and as soon as the transistors would flip, they would fry, etc. So with the core2duo, it's not so much about speed in frequency, but speed in efficiency.

The much much better deal is the core2duo, much new architecture, insanely good price, and probably will last you a good 3 years. On top of that is the potential this architecture has, it can OC like crazy if you want.

Hope that helps you out

No problem I understand what you are saying perfectly, electronics has always been my favorite subject. The 3 years warranty I thought was pretty good, so it looks as though it will be core2duo then but do you think 1.86GHz is ok or would you go to 2.86GHz is the next step up. I like the idea of 3GHz you see but the price of the core2duo is not that much difference.
