"Pentium dual-core" and "Core Duo" - what's the difference?

What's the difference between laptops labelled "Pentium dual-core inside" and "Core Duo"? I assume there must be some difference, otherwise why use two different lablels? And the "dual-core inside" models seem to be less expensive. I'd appreciate it if anyone could clarify this for me. The salespeople at the store don't seem to know.

 

The Pentium Dual Core is more like a budget current gen processor whereas Core Duo is last generations top performer. Now if it's Core 2 Duo, then that's leg up in current especially if it meets the grade for Centrino Duo which means it's from the Santa Rosa Line up that supports 800 mhz front side bus. Correct me if I'm wrong, though.

 

dual-core is generic term letting you knopw it has 2 cores

Core-Duo is a type of dual-core proc.

EDIT: I think that the Pentium Dual-Core is recent and similar to the Core 2 Duo with 1/2 the L2 cache and Core-Duo is 32 bit vs 64 bit in the Core 2. I am not sure of all the specifics tho. Intel have a good resource telling about all thier proccessors but i don't remember the url.

 

Core-Dual=2 cores
Core Duo-Intel's fancy naming scheme. Like Duy028 said, Core 2 Duo is the most recent version

 

The Pentium Dual Cores have only 1MB of L2 cache and run at 533Mhz FSB. The Core Duo's typically had 2MB L2 cache and either 667 or 533MHz FSB.

Basically as explained above both are based on the same Yonah core. The Core Duo has been replaced by the Core 2 Duo as the mainstream/highend processors. The Pentium Dual cores were then released as a budget offering. There are still Core Duo's being offered and they are typically priced inbetween the Pentium Dual cores and the Core 2 Duo.

 

The Pentium Dual Core is a stripped down version of the Intel Core Duo. The code names of the Pentium Dual Core CPUs are T2060, T2080, and T2130, and they are all stripped down editions T2050 Core Duo CPU. The Pentium Dual Core CPUs have a 1MB L2cache (local storage near CPU) instead of a 2MB cache, and some also have a lower clock speed.

Centrino Duo is not the Santa Rosa , Centrino Pro is the Santa Rosa platform. Centrino Duo is the older Napa platform.

"Dual Core Inside" could be referring to any Dual Core CPU, including the AMD Turion X2 s which are generally cheaper than the Intel CPUs.

 

Yeah they are a striped down/budget Core Duo. They are suited for basic mulitasking, surfing the web, office and other "basic" task that dont require alot of CPU power.

 

Actually, Santa Rosa is both Centrino Duo and Centrino Pro. It'll be branded Pro when it has enhanced securit features and branded Duo when it doesn't.

Also note that on desktops (which techincally doesn't apply here, but can lead to confusion), it's a stripped down Core 2 Duo. But that's only on desktops. O laptops it's a Core duo with half the Cache.

 

This is true. If you look at the sticker of a Santa Rosa Centrino notebook, it has "Centrino" in purple and below it is either "Pro" or "Duo". My ThinkPad says Pro and the Toshiba Satellite I'm testing says Duo.

 

Oh. Interesting. Silly Intel marketing.

 

I got Toshi with T2080 Pentium Duo at 1.73 that is just a tad behind my Core Duo 1.6 in PI calculations. 1:39min vs 1:29min. So I would say it ain't a noticeble diff. for everyday stuff.

 

that's because the higher speed offsets the lower cache in this benchmark. In videoediting the difference SHOULD be more in favour of the Core Duo, but if you're video editing, you'll be getting a better CPU anyways. Still, they're not bad processors, just weaker than a Core Duo with the sam clock. Hey, atleast they're not single cores.

 

Super PI is not programmed to make use of Both processing cores, and therefore, it only uses a small proportion of processing power, and it is a very poor benchmark.

 

Thanks for your help, everybody.
