Core Duo vs Core 2 Duo... a 500MHz difference

Which one is a better performer?

Core Duo T2450 2.0GHz 533FSB or a Core 2 Duo 5250 1.5GHz 667FSB?

Thanks in advance!

 

Hm I'd go with T2450, that's what I (almost) have now on my Dell T2500, works like a charm.

 

The T2450 will give the most raw performance. But if you're looking for a new computer, I would go with the T5250 as it allows 64-bit computing.

 

I'd choose the Core 2.

What kind of tasks will you be performing?

 

Using it for normal college use, and some encoding and burning DVDs

 

I have a T2430 and its fine but if i can find a T7600G I will buy that.

 

Here are my estimates MIPS and MFLOPS using SiSoft
5250 MIPS=13577 MFOPS=9447

T2450 MIPS=13390 MFLOPS=10011

So you can see the Core Duo is slightly faster CPU arithmetic but the Core 2 DUO has a faster FSB and I would suspect in overall real world experience including CPU intensive tasks the C2D should be comparable and matbe even faster in others. So I would get the Core 2 Duo newer technology and all.

 

I'd say it depends on the price. Are they the same price or is one more expensive?

 

Core 2 have a newer architecture, 64bit computing capabilities and performs better. Core 2.

 

The C2D is just $50 cheaper (laptop price). Also, do you guys think the C2D will run cooler? the Core Duo is 31W and the C2D is 35W although it is 500MHz slower. Any thoughts?

 

I would definitely think that C2d will run cooler due to slow frequency, but not by much since pretty much all of Intel dual cores run cool.

 

Unless I wanted the potential for 64-bit operation I would get the T2450 which provides better value and, I believe, the better performance.

Take the test results for the T2250 in my Samsung R20 review and multiply by 2/1.73 (to get the T2450 score) and compare them with the T5600 results in my Samsung Q35 review multiplied by 1.50/1.83 (to get the T5250 score).

The Sandra CPU scores will be very similar but SuperPi and wPrime point to the T2450 coming out comfortably in front.

C2D is $50 cheaper which ever you chose will work fine, T2450 is faster.

John, the Bandwidth on the R20 PC4200, not great my PC4200 is 33% more. Turion X2 3900MB/s. Just wanted to let you know, go AMD!

 

The R20 has the ATI (now AMD) chipset.

According to this benchmark: http://www.notebookcheck.net/Mobile-Processors-Benchmarklist.2436.0.html
the T2450 is faster with 3Dmark05

1568 vs. 1298

quite a margin.

 

I am blaming the Intel's memory controller vs Turions on board memory controller not the chipset. I do not have a wide range of benches but the on board MC does seem to be higher bandwidth.

 

I faced this choice too - except in my case the T5250 was attached to a DV2550 and the T2450 to a DV6426. ~$300 price diff in favor of the older tech - but with a slewth of configuration differneces. But if they were similarly spec'ed and were in the same price range, I would reconsider.
