compare intel core duo and core 2 duo...

i am buying a new laptop for the first time in 4 years. and, because of my job and traveling i have not kept up with the whole processor race. so, i am wondering how the core duo chips, such as a t2500 2 ghz, compares to the power and speed of a core 2 duo, such as a t7400 2.1 ghz?

 

You can make detailed comparisons between the CPUs you have mentioned at Tom's Hardware Mobile CPU charts. If whatever you are using is 4 years old then even the bottom end of the dual core series (T2050, etc.,) will seem very fast. Effectively you have a couple of 1.8 GHz Pentium Ms sharing the workload. Unfortunately, Tom's CPU charts do not include a Pentium M for comparison. Maybe that will come - the charts are subject to ongoing refinement.

10% more performance and 10% more power consumption along with 64-bit support.

 

It depends on the task you wish to do. Core Dup is based of the Yonah core, and Core 2 Duo is based of the Merom core. Merom is a slightly faster architecture, so it will perform about 10% faster in processor dependant tasks, such as video editing or encoding. The averga euser, who uses a cmputer to word process and surf the Internet will not notice any difference between the two processors.

However, Merom is a 64-bit enabled processor, so it will be able to handle 64-it applications, when they release onto the consumer market. If some of applications that you wish to use, will implement 64-bit, then you will see a performance increase.

Battery runtime is about the same with both processors. The architectures are very similar, as are there efficiencies. That means the energy they use will be roughly the same. Other things, like the graphics card will have a bigger impact on battery runtime, if you are comparing the Core Duo processor to the Core 2 Duo.

Enjoy.

 

thanks guys. i appreciate all of the help.

the laptop i'm on now is a toshiba p25 satellite, 2.4 ghz pentium 4, 2 gigs of ddr, an 80gig hdd and a 17 inch widescreen. it's still pretty good, but i have to have an upgrade. i love the fingerprint scanner, the scroll bar on the touch pad, an on/off button on the touch pad, touch slide controls, monster fast processors, monster fast memory, video card with 300 meg's of vram, etc...

while i love the sheer power of the sony's, i really like the layout and look of the hp pavilion dv9260us. however, traditionally hp makes great printers, but not so good pc's. so i don't know if they are any good now? i was never a big fan of sony either, but they seem to be on the top of the hill right now. i want the power of a true gamer machine, and the common sense and reliability of a business pc. any other help is appreciated.

 

Anything you get will be better on the battery and faster than your current rig. Even AMD based machines. I'd take the HP over the Sony though, mostly because Sony hates it's consumers almost as much as Microsoft does

 

HP notebooks are very good. The build quality and appearance of their new notebook range is much better than most other models. The performace if the notebooks is also very good. If you go with a HP, I don't think you will have any main issues, with the actual physical side. They do include a fair bit of bloatware, but most manufacturers do. It is still possible to remove most the bloatware software, however.

 

thanks a lot. it is amazing how much things have changed in the last four or five years. i was just reading in another post that the new dell is an excellent machine. but when i was in the business five years ago, dell was a dirty word!!! i mean, i wouldn't buy a dell for anything back then! are they really good machines now?

 

Dell's are more than acceptable, and they do offer very good value for money. Most of their notebooks apprt from the XPS lines, and the more specifications orientated notebooks are well rpcied, and built to a good standard. In comparision to some other notebook manufacturers, they seem a little less built, but for someone on a budget, wanting a good system, Dell will most likely offer a good deal.
