Eight.
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.
Pentium Dual-Core was created in 2006.
Both processors are in the Pentium Dual Core family. The Pentium Dual Core E2200 is better than the other.
The Intel Pentium Dual-Core is much faster.
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).
The Intel Pentium D, Core Duos (and Solos), Core 2 Duos (and Quads), Pentium Dual-Cores, and the Core i7.
usually a Pentium core.
Yes, as long as you have a 64-bit capable processor. A Core 2 Duo, Pentium 4 (Cedar Mill Core), or a Pentium Dual-Core would be capable. An Intel Core Duo is 32-bit only.
you need to be more specific (specific dual core pentium model) as various dual core pentium processors have been created over the years that use several different socket types
Any processor that is an Intel Pentium III, Pentium 4, Pentium D, Core Solo, Core Duo, Core 2 Duo, Core 2 Quad, or Core i7, as well as most AMD Athlons, AMD Athlon 64, AMD Athlon 64 X2, and AMD Phenom.
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.
No. The Pentium M is an older, 32-bit only processor. The Pentium Dual-Core is faster and supports 64-bit operation.
