what is the difference between Dual Core and Core 2 Duo processor?
I want to buy a laptop what i will do?
Can some body please explain the difference..

I have a notebook with a 940GML / Celeron 440. Can i upgrade to a CoreDuo FSB533?

Anand,

I would like seek your advice. I want to buy laptop but i confused on the Centrino Duo Core 2 Duo and Intel Core 2 Duo. I looking at the Acer Aspire Laptop Centrino Duo Core 2 Duo and Compaq Presario Intel Core 2 Duo. So i would like to know the difference. Please assist. Both is Core2 Duo but the Acer is with Centrino. Is Acer better or Compaq better?

Hi,

A few questions:

(1) Can we assume that the power draw numbers represent the best possible performance one can expect from Core 2 Duo mobile systems one can purchase today, or, should we assume that they represent typical performance, or, can we say we don't know because we only used one sample of Core 2 Duo?

(2) What about the Core Duo (Yonah)? Theoretically, if Intel supplied all CPUs to the reviewer, I as Intel would supply the best quality (lowest power draw) Core 2 Duo, and the worst quality (highest power draw) Core Duo for my reviewer to perform the review on.

Thanks!

Can a Core 2 Duo processor be fitted into an Apple Mac Mini using their new Intel Core Duo processors?

one of the funny things about performance and battery life is that if you can complete a task quickly enough thus returning your CPU to an idle state faster, battery life will grow even though instantaneous power consumption may be higher.

Actually this is not correct: a CPU that's clocked higher also needs a higer voltage. Therefore, doing the same amount of work faster will require more energy than spreading it out over a longer time (in theory).
For this to be true in practice, you'll off course need to factor other things into account, like I/O-devices (which may have less choice in sleep states: keeping the hard disk spinning for a longer time can destroy the gain you had by slowing down the CPU), etc...

"Eventually" we will have processors based on light particles vs electrons; but that is "eventually"; lets talk about the very near mobile future shall we (1 year).

1. EM64T enabling - Will DEFINATELY boost and widen the performance gap b/w Core D & Core2 D. Especially with the Vista 64bit OS system installed. EVEN when u run 32bit applications on it.

2. Quad-Core 'Santa Rosa' - Another great stride by Intel to boost performance (of course at the expense of battery life (which i might add, shouldnt matter much since most laptop users use the laptop near AC outlets). I am definately going to wait until next year to upgrade to a new laptop. Plus Vista will take advantage of the extra cores.

3. FSB, and Battery Life - Comon, lets not fool ourselves; Intel can full well come out with a 1066 config for mobiles WHENEVER they want. AND mobile MOBO can be fabricated to take advantage of it JUST as fast. BATTERY life is the ONLY culprit. I would be the FIRST to buy such a laptop. Why use a clumsy desktop with so much wattage when you can get slightly less performance with much better gains to offset the balance regardless. Lets get one thing straight ... Desktops are losing ground, Laptops are the future.

4. Shared L2 Memory Cache - The 1st Core D processors were CRUDE at best in this regard. Core 2 D Proc.s will SHARE the FULL L2 cache.

Ehh who knows what will happen in 2008, and 2009 .. IBM and Georgia Tech's 300GHZ (room temperature) processors may be producable by that time ..

Sometimes, I feel as if the corporate giants stagger the new technology into consumer hands in stages so that they may reap the profits.

I've got a Toshiba U205-S5002 which has a 945GM chipset. This article says that the 945GM supports Core 2 Duo. I need to find out now if the processor in my laptop has a PGA Socket-M or BGA CPU. I've checked Toshiba's support pages, but can't find any info. regarding the CPU's interface w/ the mobo.

Anyone have any info. regarding the U205-S5002's CPU interface?
