Yes, it's.
They are approximately the same at the same frequency.
They are the exact same technology, so one is not actually "better" than the other. Intel Pentium Dual-Cores use the same architecture as the Intel Core 2 Duo, just with a smaller L2 cache size. This makes the Dual-Core slightly slower in intensive applications than a Core 2 Duo at the same clock speed. A Pentium Dual-Core will still outperform a Core 2 Duo of a lower clock rate. Pentium D's are older Core 2's renamed to promote newer CPU's.
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.
Very little, actually. The Pentium Dual-Core has a smaller L2 cache, making it just slightly slower than a Core 2 Duo at the same clock speed.
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.
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 Dual-Core is much faster.
Core 2 Duo is FASTER. Pentium M is based on OLD technology and run on a SINGLE PROCESSING CORE whereas the CORE 2 DUO has 2 PROCESSING CORES. It has higher CLOCK SPEED, FSB, CACHE. Simple!
The Intel Pentium D, Core Duos (and Solos), Core 2 Duos (and Quads), Pentium Dual-Cores, and the Core i7.
usually a Pentium core.
Pentium 4 vs. Dual CoreThere are MANY differences between these two generations of Intel CPU's. Most notably, Duo Core CPU's possess two processing cores opposed to the Pentium 4's single processing core. While a Duo Core CPU may be operating at a lower overall operating frequency, it is still much more powerful then a Pentium 4 considering it's improved FSB speed, cache size, multiple cores, efficiency, etc.
