I am (still) searching for a new laptop...

The specifications are quite confusing. Often what you find here is not there and what is there is not here!

I was wondering if there's some significance difference in performance between Dual Core and Core 2 Duo?

Thanks.

This distinction is confusing in two ways!

Dual Core is a description of any microprocessor which has two processing cores built into a single CPU chip.

Unfortunately, Intel decided to use Core as a marketing name for the type of processor that superseded the Pentium M CPU, and then to continue the theme, but make it even more confusing, by naming the processor following the P4 as Core 2.

Having done this, Intel couldn't very well have a Dual Core Core 2! So if an Intel Core 2 CPU has a single core, it is called a Core 2 Solo, if it has a dual core, it's called a Core 2 Duo.

So Core 2 Duo just means the Intel dual core CPU.

If I got you right, Dual Core & Core 2 Duo, both refer to the same thing?

How about 2 laptops with the following specifications:

a => Processor - Intel Pentium Dual Core T2370 / 1.73 GHz ( Dual-Core )

b => Processor - Intel Core 2 Duo T5670 / 1.8 GHz ( Dual-Core )

What is the difference or why the distinction?

What I consider a good explanation at http://www.cnet.com.au/forum/?mode=viewthr...416&tindex=, see comments by Canberra.

For those inclined to more technical detail on comparison: http://www.devhardware.com/forums/intel-pr...duo-188459.html

Well, yes, Dual Core means any CPU made with 2 cores. Core 2 Duo is one of Intel's designs using 2 cores.

How about 2 laptops with the following specifications:

a => Processor - Intel Pentium Dual Core T2370 / 1.73 GHz ( Dual-Core )

b => Processor - Intel Core 2 Duo T5670 / 1.8 GHz ( Dual-Core )

What is the difference or why the distinction?

In reading Canberra's explanation linked by Hamluis, note that the T2370 processor is a Mobile Pentium:

http://processorfinder.intel.com/details.aspx?sSpec=SLA4J

The T5670 is a bit more complicated, the type isn't listed in general processors by Intel, it appears to be a number used by manufacturers (an OEM release), and seems to have the same specification as the T7100:

http://processorfinder.intel.com/details.aspx?sSpec=SLA4A

The T2370 is a less advanced chip design. Comparing the specs, it has less cache, lower bus speed, slightly lower clock speed and the same power consumption rating. So you get less performance without any compensation like longer battery running time.

Thanks for the links and explanations.

I am thinking of getting this Toshiba laptop with the following specification:

Processor - Intel Pentium Dual Core T2370 / 1.73 GHz ( Dual-Core )
RAM - 2 GB (installed) / 2 GB (max) - DDR II SDRAM - 667 MHz ( 2 x 1 GB )

Hard Drive - 250 GB - Serial ATA-300 - 5400 rpm
Operating System - Microsoft Windows Vista Home Premium
Screen - 17" TFT 1440 x 900 ( WXGA+ ) - TruBrite
Optical Drive - DVD±RW (±R DL) / DVD-RAM
Graphics - Intel GMA X3100
Bluetooth - No
Notebook Camera - Integrated - 1.3 Megapixel

Please the link here for the extended specification: http://www.laptopsdirect.co.uk/Toshiba_Sat...=lddealtime#top.

But there's another laptop with these features:

Processor - Intel Core 2 Duo T5670 / 1.8 GHz ( Dual-Core )
RAM - 3 GB (installed) / 4 GB (max) - DDR II SDRAM - 667 MHz ( 1 x 1 GB + 1 x 2 GB )

Hard Drive - 160 GB - Serial ATA-300 - 5400 rpm
Operating System - Microsoft Windows Vista Business / XP Professional downgrade
Screen - 15.4" TFT 1280 x 800 ( WXGA ) - TruBrite
Optical Drive - DVD±RW (±R DL) / DVD-RAM
Graphics - Intel GMA X3100
Bluetooth - No
Notebook Camera - Integrated - 1.3 Megapixel

I guess the 2nd one is more powerful than the 1st... but how powerful I'm thinking? The 1st one costs £439.97 and has some features that I need, like a large screen (17") and hard drive(250GB). The 2nd one costs £549.97, £110 more than the 1st one but has Intel Core 2 Duo and 3GB RAM. However, less screen size (15.4") and hard drive storage (160GB). It also has Vista Business, which I really don't need- Home Premium is enough for me.

I don't know... just needed advice especially on performance. I feel like going for the 1st as it suits me better and costs less. But in terms of performance, just wondering if it would be better to get a Core 2 Duo...

Thanks.

Well...do you do anything on your system where the alleged performance differential...is worth worrying about?

I mainly use for Internet, e-mail, some chatting, watching videos online and downloading, and some occasional Word... I'm not into gaming.

Thanks.

It looks like I'll be going for it unless I find a better deal...

Well...once you settle on a particular system or device...the Web is a good source for comparative shopping.

Just do a Google for that particular model and you should get a list of different vendors pricing same. The bizrate website is one that I always tend to use for this purpose...but there are others that are just as informative.

I have been doing a fair amount of googling and price comparison. I use pricerunner to compare prices, but I have also tried few others including bizrate. The cheapest I could find is at the site I linked to. I've also been searching for a good product review for this Toshiba model, but failed to find one.

Anyway, I'll browse for another day or two before I order.

Thanks again.

Ordered the laptop and got delivered today, but without any recovery disks or OS CD... I know they don't normally send with the OS CD but was expecting some recovery disks. I sent them an e-mail and got a reply informing me that I need to create the recovery disks myself. What an unnecessary trouble. Couldn't they just send one?!

That's the standard way that (some) boxmakers have been doing it for several years.

They provide users/purchasers guidance and expect them to read it...various things a user might want to know about the system purchased.

The boxmakers/manufacturers usually have a standard policy/procedure on their website which also covers the whole restore/recovery CD procedure.

Best Buy has been notorious (in my mind) for making money by selling systems and then charging purchasers to use the built-in procedure on the system...to create disks which purchasers could have done themselves at home, had they been willing.
