Upgradeability with new dual core processors?

I'm looking at the new Dell e1705 specifically... I'm wondering if you will be able to upgrade the processors on this later on?

To get the highest speed cpu Dell is offering is a helfty price increase.

Just considering all my options.
:decision:

 

If you get a mediocore proc you shouldn't have to upgrade for a while. A P-M 2.0 runs at about what a P-4 3.2 with HT runs at. So the upgradability shouldn't be a huge factor. But if you are looking for way later down the road it might be a little bit of a factor.

 

In virtually any laptop you an upgrade to the top end of the cpu in the same series. So, if you get a low end Core Duo, you can later on add the top of the line Core Duo. But it is never a gurantee.

Also Intel will be releasing the 64bit version(Merom) sometime by the end of this year. Whether you can upgrade to that is unknown although it is possible that Merom will be pin compatible with Yonah(Core Duo) and if there is proper BIOS support, you should be able to switch to the 64bit version.

 

I've read that the Merom will require a different chipset...Upgrading Yonah to Merom will be not be possible without changing the motherboard

 

What kind of comparison would you make for the Duo Core 1.83ghz to a P4? I find it strange to be buying the newest processor and the speed is only 1.83 Ghz compared to P4's at 3 or 4 Ghz. I understand their are other factors involved then just core speed. Is the duo core 1.83 ghz processor faster then a P4 (for single threaded applications).

 

I believe the commonly accepted multiplier to compare Pentium M to Pentium 4 is about 1.8. For example, a 1.86 GHz PM is about as fast as a 3.4 GHz P4. And considering the new Core Duos are generally faster than PMs in most regards, I'd say clock for clock the duos are considerably faster than P4s.

 

So, could I upgrade a Solo to a Duo in the future? I'm thinking Solo now due to the rebate being valid for it but not the Duo.

 

Here is possibly a very stupid question but being an AMD man most of my computing experience, i need help!!!

Does anyone know if i can upgrade the cpu in my sister's laptop she has an Asus Model : W5Ge740SM58PG
Intel Pentium M-740 Processor 1.73GHz 533Mhz

can it be upgraded to either the Yonah or Merom dual core, apparently it is a socket 479... the Yonah appear to be socket 479 too, but i do know that Intel are a pain in the *** with their sockets and upgradability...

just a newb question from an intel newb!!!!! the processor is pretty sweet as it is, but just thinking ahead to the days of Vista when we are all going to need super computers just to run the OS!!!

thanks for any help offered up!!!

 

no, as PM's are not socket compatible and I believe took out a pin on the Yonah processor.

 

The only processors that a Pentium M compatible motherboard can use is a Pentium M or a Centrino. You can not put a Core Duo (code name: Yonah) or a Core 2 Duo (code name: Merom) in one because of the difference in sockets. Bother processors are socket 439, but the pins are arranged differently so that they can not be interchanged.

Core Solo and Core Duo run off of the same motherboard. So if you get a system with a Core Solo, you can upgrade to a Core Duo simply by replacing the processor. Intel has explicitly stated plans to make Core 2 Duo pin-compatible with the current "Core" motherboards, so unless the individual manufacturers don't support them in the BIOS, Core 2 Duo should be a drop-in upgrade for any Core Duo users now.

 

ok thanks for the heads up! the processor is plenty powerful enough for my sister atm, but i was just thinking in the same vein as Tim the Toolman here, getting a little caught up in the dual core hype/reality!
