Core 2 Duo 1.4 GHz T5270 vs Dual Core T2370 1.9 GHz?

Well the core 2 duo was significantly better, but not sure if it's 500 mhz faster, if it's a work laptop then probably the core 2 duo will be more energy efficient and you'll not notice the speed difference much anyway, I have a 1.8 pentium dual core (the new ones not the older ones, yonah core) and it works fine.

Core 2 Duo T5270 - 1.4 GHz, 2 Mb, 800 MHz, P
Pentium Dual Core T2370 - 1.73 GHz, 1 Mb, 533 MHz, P

Even though the T5270 is clocked slower (1.4 vs. 1.73 GHz) I expect that it would be faster for most tasks. That is just my expectation... assumption... I searched but couldn't find a review directly comparing the two.

Honestly i dont think you will feel much diference either way. They are quite similar in performance, and in a laptop they will be throttled to lower speeds most time anyway. On your case i would choose the one with more memory or better VGA. The HDDs should the same speeds i guess. Being a laptop, if the rands are the same, check how has the best customer support.

I have a Core Duo T2350 in my laptop (1.86GHz, I think) and it's handled everything I've thrown at it; that doesn't include recent games as the crappy Intel integrated graphics chip can't handle them anyway. As mentioned, most of the time it's throttled way back to increase battery life, so the performance difference would only matter if you were running on mains power anyway.

The Core 2 Duo will be more energy efficient because of the lower Clock and will also support 64bit Computing. The Older Core Duo will only run a 32Bit OS, so it is limited. Both should offer reasonable speed for any task, but I'd imagine the higher clocked Core duo would have the edge because of the higher speed despite the older tech.

the T2370 is based on the Merom core and DOES run in 64bit.


This is NOT a core duo.

Here's the numbers:

wprime 32M calculation:

Dell Vostro 1500 /w T5270 - 53.827 seconds
Apple iMac /w T2500 - 47.046 seconds
Acer Travelmate 8204 /w T2370 - 50.947 seconds


the t2370 is faster then the t5270, the bus speed cant overtake the 500mhz less in speed

Sorry Didn't realize, the Poster stated the second option was a Core Duo. That's why I stated it would not run 64Bit



It also seems the T2370 runs at 1.73 Ghz and not 1.9Ghz.

Thank you all for your input particularly macer1. This will surely help in deciding.

However I am confused regarding core duo and core 2 duo. My understanding was that all the dual core models of intel processors which were not core 2 duo were core duo? Is that not correct? What would T2370 be called if not core duo?

Ever since Intel moved to the Core series, most of their chips have been called Core 2 Duo. The Core series obviously came before the Core 2 series, and was a notebook-only line (of course, you could always use it in a desktop, but it was intended for notebooks.) Core is more similar to a Pentium M than a Core 2 chip.

As for your question, if a chip isn't branded either Core or Core 2, it could be called Pentium Dual-Core (yes, with the hyphen.)

Certain models are based on Core Duos, while others are based on Core 2 Duos. I'd expect more of these chips to be based on Core 2s now, though, since Core Duo was discontinued a while ago.
