What is the difference between pentium and core 2 due microprocessor??

Question

one of my friend says that in pentium processor data transmits in 1 throgh 1 channel while in core 2 due technology data transmits through 2 channels....is it right?? or any other metter is there??

Answer 1

Okay. I will just sight an specific specific of two processors.

Intel Processors

The Intel Pentium Dual Core T2330 is a low-end dual core processor for laptops/notebooks. "Pentium Dual Core" processors closely resemble Intel Core Duo processors, except they have only 1 MB of L2 Cache instead of 2 MB. The Intel Core 2 Duo T5450 is also a dual core processor for laptops, but it uses Intel's newer 64-bit "Core 2" architecture.

A dual core processor allows simultaneous, parallel program execution - for example, running a filter in Photoshop while ripping an MP3: each process would be executed on a separate "core". It's like having 2 cpu's on one chip. The Pentium Dual Core T2330 runs at 1.6 GHz, has 1 MB of L2 Cache and a Front Side Bus (FSB) speed of 533 MHz. The Core 2 Duo T5450 runs at 1.66 GHz, has 2 MB of L2 Cache and a FSB speed of 667 MHz. The T5450 could be expected to run 25% faster than the T2330 due to its improved Core 2 Duo architecture, larger L2 Cache, slightly higher clock speed and faster FSB

Answer 2

Core 2 duo has two processor cores, so it can run more than one process at a time (single-core processors must divide their time up between all the threads).  Also, the core processors have a slightly different architecture, allowing them to run at lower clock rates (and thus cooler and consume less power) while still getting the same amound of work done.

As far as I know, Core processors, like Pentiums, have a single front side bus which transmits information between the processor and the northbridge.
