depends on the core duo, but most core duo's are better than the older dual core
The Core Family
Windows 7 is capable of running on any x86 or x86-64 compatible processor that runs at at least 1 GHz. This includes late-model Pentium IIIs, Pentium 4s, Core, Core 2, Pentium Dual-Core, Core i3, Core i5, Core i7, Xeon, Athlon XP, Athlon 64, Athlon 64 X2, Phenom, Turion, and Opteron processors.
There is no Pentium 5 processor. The mainstream (non-budget) Pentium line ends with the Pentium D, which is essentially a dual-core Pentium 4. The Core Solo, Core Duo, Core 2 Duo, and Core 2 Quad all have a very different architecture from the Pentium 4.
No. A Pentium Dual Core is a cost-reduced version of a Core 2 Duo. Think of it as the new equivalent of a Celeron. The Pentium D is basically a dual-cored version of the Pentium 4, but is far less efficient than a Core 2 Duo (or a Pentium Dual Core).
No. The Pentium M is an older, 32-bit only processor. The Pentium Dual-Core is faster and supports 64-bit operation.
Probably the Pentium Dual-Core, as it is the most recent processor to bear the Pentium name.
Intel centrino-dio is better for the current market.
yes
As with any electronic product be it software or hardware, one can find the latest Pentium-core processor available at the Christmas season. Pentium-core processors are associated with the Dell company.
The Pentium D is basically a dual-cored version of the Pentium 4. It is nowhere near as efficient or powerful as a Core 2 Duo, and it actually generates slightly more heat than a Pentium 4.
An example of a single core Processor is anything from Intel's first processor to the late Pentium 4 era. There are also some single core Pentium Core 2/duo line products but those were very cheap for consumers.
An Intel Pentium Dual Core processor is a CPU (Central Processing Unit) and is effectively the "brain" of most computers. The Pentium processor was most common in the early 21st Century and has subsequently been replaced with faster models.
