I'll put this simply so I don't make a fool of myself

I'm kind of confused. I'm thinking of buying a new PC and I'm looking at Intel Core 2 Duo processors, I see ones that go from 1.86GHz to 2.67GHz (and probably higher). Why are they only that amount? Is it because the Duo means they are double that? Because I see other computers at 3.0GHz+ ?

Thanks <3

Nope they go faster, like this,
Linky

or atleast they will be soon

It means your computer will have two processors. They will run at the speeds you buy, but having two is better than one. There is the Core Duo and Core Duo 2. The Core Duo 2 is a more refined release, which uses less power and is more efficient (hence it is more expensive). Intel also produce a quad core as well now .

Duo Processors do make a difference, you can really tell the difference .

Core 2 Duos have two cores in them, so basically you'll get two 2.67GHz processors running in parallel.

e.g
User runs a video conversion on a 3.4GHz processor; it takes 30 minutes, but he can't do anything else whilst running the conversion because his CPU load is at 99%.

User2 runs a video conversion on a 2.6GHz Core 2 Duo; it takes 40 minutes, and he can do everything else he wants to do because Core1 is running at 99% and the other one is free to run whatever he wants.

Thanks guys, helps a lot

About a year ago, I posted a rather lengthy explanation of how two cores affect performance.

I should add that Core 2 Duo in particular, compared to AMD's and earlier Intel CPUs, performs amazingly well.  You can't go wrong with it.

Ignore everything you previously based clock speed on. The only reason you see clock speeds like 4ghz on Pentium 4s is because intel doubled NetBurst's pipeline, meaning they could get much higher clock speeds. However, this also means the possible instructions per tick is halved, meaning you would need a 4ghz Pentium 4 to match the performance of most 2ghz AMD processors; and of course, clocking a processor at 4ghz creates heat and power consumption problems, which is why you never saw Pentium 4s outperforming AMD processors. however, with the Core line, intel fixed this issue and now just about every Core 2 Duo processor would wipe the floor with AMD's entire processor market.

Thanks Adeptus, I read your explaination.

I'll be confident in getting a Core 2 Duo processor now

Intel Duo processors I believe out perform AMD any day. Intel have really hit a brake-through with this technology .

why did i see this coming? a simple thread asking why this was better or how it worked and it turns into all these statistics and figures and comparities against everything else. stop its hurting my head.

but thanks i have leanrt some stuff =p

Well I'm glad it was said because my computer and my dads computer both are AMD's, so from now on I'll make sure the processor is from Intel

Erm, just to point out, that Intel Core 2 Quad processors are out. These aren't really 4 individual cores, they're two dual cores running in tandem. It's hard to explain. Anyway SEE HERE for the current top of the line Intel processor. (I wants me one, but for a full system it's like 6 months pay ).

You may also notice that AMD processors aren't really clocked above 3.0GHz either. It's something to do with not being able to send impulses any faster, or something.

absolutely right.

intels ftw, always.

I would still buy intel even if amd was better... heard some stories from people who do know...

Heh, that's cool. Don't think I need one that fast though, I'm sure a Inten Core 2 Duo will be fine, won't it? I'm not doing any extreme gaming or anything.

When in doubt, listen to Theo.

Thanks for all your suggestions, Jhrono is helping me out on WLM
