How different are a desktop P4 3.0cGhz cpu vs Core Duo 1.66Ghz

which is supposed to be faster?

 

The Core Duo is the better CPU. It is a much more efficient CPU. Plus it runs much cooler and has better battery life.

 

I'd estimate the performance to be *roughly* equal. It's not exactly the fastest Yonah, so a Northwood P4 might be able to keep up.
But the P4 will generate twice as much heat and drain your battery a lot faster.

 

For multi tasking the p4 would be left behind in the dust of the core duo. In single threaded tasks they are probably the same. The Core Duo is the way to go.

 

I ran super pi to calculate upto 2M on my Pentium4 3.0 Ghz HT and the result was 1min 44 secs. My Core Duo 2 Ghz scored 1min 15 secs on my notebook.

 

Cool. I should do that!

My P4 3.0cGhz is a desktop cpu with Hyper Threading, just like yours.

Any tests to see how they handle multi-tasking?

 

core duo has two cores. It wins in the multi-tasking dept hands down.

 

Face it, P4 has nothing on Core and Core2. Everything the P4 can do Core/2 can do better, everything. I think my Core Duo is rated somewhere to what a 5.2ghz P4 w/HT, according to a chart I saw. But yeah take the core, P4 will still get the job done for everyday use, and it will for a while. But if you do alot of multi-tasking, gaming, and use a notebook, Core/2 is the best.

 

Anyone clocking their Core Duo's yet? Is it as simple as changing a T2300 to a T2400 by incrementing the cycles?

 

Which means nothing at all, except that the CD is better at SuperPI.

 

Alright guys, here are some benchmark comparisons for you.

The first attached image is arithmetic benchmark (ALU and FPU are tested) comparison. On this benchmark P4-C 3.0GHz ALU performance is less than 63% of CD T2300. P4 FPU performance is slightly better (it actually is equal to that of T2400 that is not pictured).

The second attached image is a multimedia benchmark. As you can see, P4 is blown away by Core Duo.

The benchmarks also include T2600 and P4-E 540 3.2GHz for comparison.

Also, as I said earlier, since Core Duo has two cores, it will win in any 'multi-tasking benchmark' hands down.

Hope this settles it

 

Of course that doesn't settle it.
As with SuperPi, all this shows, is which CPU is best at some arbitrary synthetic benchmark. That's not the same as real-world applications with real-world code.
(I'm not saying the P4 is faster though. It's an abomination that should have never been designed, and overall a Core Duo is a much nicer CPU. But synthetic benchmarks still don't show anything useful. The P4 has a whole range of shortcomings that don't really show in ALU benchmarks. for example)

Also, I can't remember what P4-C refers to, but is it Northwood? (Since that was the original question). And how is the rest of the reference system equipped?

 

Haha what ferrari is better F430 or F360? It's never going to be settled I think. But I hope noone will dispute that CD T2300 is a MUCH better processor for a notebook than P4-C 3.0GHz (that's what the original question was - see thread title)

 

They will be about par in performance in most tasks except multithreaded applications where the core duo would beat it to death.
