Core Duo Vs Core 2 Duo

whats the difference? and is it worth paying extra for it? Core Duo Vs. Core 2 Duo?

 

Core Duo is slightly older than Core 2 DUo, and lacks a few advancements. The main one being 64-bit. The newer Core 2 Duo have 64-bit, and some of the more powerful ones, have twice the L2 cahce (4MB). The claimed speed increase from Core Duo to Core 2 Duo was around 20%, however that only appears to be true for the models clocked above 2.00 GHz. Even then, the performance increase, is around 10%. Performance between slower Core Duo processors is about the same as slower Core 2 Duo processors. The Core 2 Duo will probably be ver slightly faster. The price for these processors should be the same clock for clock, so it makes sense to go with Core 2 Duo. Hope this helps.

 

Zero said it well. I believe the 20% increase is accurate, but only for Core 2 Duo processors with 4 MB cache, and then only on specific applications that can make use of it. Really, a 10-20% increase should be seen on 4 MB cache processors depending on the application, and the 2 MB Core 2 Duo's more like 5-10%.

Since you posted in the HP forum, I'm assuming those are what you are looking at. HP is primarily just offering the lower end Core Duo's now, which are clocked slower than any of the Core 2 Duos so in that case there would be a considerable boost in speed.

And again, 64-bit processor vs. 32-bit. Another potential speed boost but only if you are running 64-bit Windows and a 64-bit application -- which are few at the moment.

If you can afford the difference, I would go with the Core 2 Duo just for the higher clock speeds (again, assuming you're looking at HP configurations). The other aspects are just bonuses.

 

What if I run the 32bit version of vista? will the core 2 duo still make a difference?

 

Hey jadedraverla, in your sig it says you have a Nvidia Geforce GO 7200 with 256 MB shared memory. How is that possible, I thought the DV6000T was the only one with 256 mb, and it says you have a 2000t, is that just a mistake or did they offer an upgrade?

And sorry for the offtopic post.

And to answer the question, the main difference is the cache sizes, and they made some advancements in the architecture, which resilts in a 5-10% boost in some programs. Yes the Core 2 Duo will still make a differnce, because of the advancements in architecture, and design.

 

GeForce GO 7200 should have a 128MB shared memory right?

The amount of shared memory in the Go 7200 isn't hardcoded into the processor. Nvidia's XP driver sets it at 128 MB total. The generic Nvidia Vista driver (when you have 2 GB of system RAM) defaults to 256 MB shared memory. I should really remove that part from my sig or explain it there, but I'm lazy right now.

And to the original poster, yes you'll see a boost in performance on 32-bit Vista... you just won't get the potential added bonus of 64-bit apps on a 64-bit OS.

 

I wouldn't consider buying a CPU that isn't 64-bit capable these days. There's not enough of a price difference to warrant the risk. It's a shame that it took Intel so long to copy the AMD64 instruction set that people still have to think about this question. Well, Intel fans at least.

 

So, do you see a performance increase with the 256 MB of shared memory compared with the 128 MB.

 

There's really no way to compare. Nvidia's Vista drivers are terrible right now, so any speed benefit of the extra video memory is offset by the Vista slowdown.

 

Oh all right cool.

 

Now what if one purchased a Core Duo just before the Core 2 Duo came out? Is it worth either the hassle of a return or an upgrade of the CPU? Looking at a dv2000t with 2gb ram, Intel 950 graphics, 1.86ghz Core Duo, 120gb hard drive. It's not my main PC (my desktop is).

 

Nope. Keep what you have until you need 64-bit and/or something faster (say, a decent GPU).

 

SuperPi to 2 million digits dropped 11 seconds for me going from a core duo 1.73 w/ 2gb to a core 2 duo 1.83 w/ 1gb. (1:22 to 1:11).
