Hello,

I am about to buy a laptop and i'm stuck with the processor decision. the two choices I have are exactly the same specs except for the processor. One has an Intel Core 2 Duo 1.3 GHz SU4100 and the other has an Intel Pentium 1.3 GHz SU4100. The Pentium is $100 cheaper, but I'm not sure whether the difference in price is justified.

Any advice???

The Core 2 should be easily the faster of the two. Can you be a bit more specific regarding the exact models?

You provided code SU4100 for both units. Either thats a typo or those lappys have the same cpu. Modern pentiums are just Core 2's with less cache, so maybe one unit just called it a Core 2.

There is a 1.3 ghz core 2, so assuming the numbers are a typo, you can expect the Pentium to be about 10% slower than the Core 2. Not worth $100 to me, all other things being equal.

pentium dual cores are on the same architecture as the core2duo's. they have slower fsb speeds and smaller cache sizes. All things considered I have a e5300 oc'd to 3.6ghz at work and it does the job. Like play l4d2 and mirrors edge.

Pentium dual core is a cut-down version of core 2 duo with smaller cache memory and slower frequency. How? Let's take Intel's WOLFDALE desktop CPU architecture as an example. At intel's factory, any CPU that comes out with one or more cores not reaching high frequencies or with a defect at the area of cache memory is branded as pentium dual core (E5200, E5300,E5400,...) and sold with a cheaper price. Any CPU that comes out from the factory without any defect (completely normal, in other words: has the full 6 MB cache memory and can reach the wanted frequency) is branded as Core 2 Duo (E8200, E8300, E8400, E8500, E8600) and sold for a higher price.

By this way, CPU manufacturers (Intel and AMD) make use of all the CPUs in the silicon wafers and sell them all, including the defective ones.
