A P4 processor is fast, but the Pentium D is much faster. The D stands for Dual Core. This means that they have two on die processor cores instead of just one, as the Pentium 4 does. Two processors also makes it better for "demanding" applications.
The Pentium D is better if you have a motherboard that will utilize the technology. As stated the Pentium D is Duel core. This is Intel's way of creating the closest environment of a true duel processor. The HT is for Hyper-Threading which acts like a zipper and allows several applications to process at the same time. The Pentium D will really make a difference when used with the new 64 bit operating system.
However, HT (Hyper-threading) P4, does have emulated Dual Core processing. In short, the processor makes the computer think its runing a dual core. The Pentium 4 also has a couple different levels, so if you are trying to make a comparison, make sure that you look carefully.
Although neither can match the power of an Athalon or an AMD x2 processor. If you are buying, get something with 64 bit processing. WAY faster and better for games and high graphic systems.
Pentium 4 is a single core processor with a max CPU speed of 3.8Ghz Core2Duo is a dual core 64-Bit processor with a max CPU speed of 3.33Ghz. The Core2Duo would be much faster due to it being a dual core. A Dual core 1.5GHZ processor would be faster than a single core 1.5GHZ because a dual core process is a combination of two independent cores into a single processor. Its almost like having two processors.
p4 meaning Pentium 4? Dual core means it has two processors in it, each running to speed up performance in your computer.
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.
The Pentium D is essentially a rebranded and double-cored version of the Pentium 4. The Core 2 Duo is a much more efficient and powerful processor.
The core 2 duo is faster.
The difference is that Core Duo processors have to "engines" instead of one. With other words, Core Duo means 2 Intel processors in the same time working!
usually a Pentium core.
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.
The Pentium Dual Core has a smaller L2 cache than a Core 2 Duo. It essentially fills the same role as the older Celeron processors; a cost-reduced version of a more powerful chip.
The Core 2 duo is the best
The difference between a Pentium and a Centrino is that the Pentium and Core Duo, etc, are configured with the Centrino containing less capability and being marketed at a lower cost point than the Pentium branded product.
The Intel Pentium line encompasses many processors of many different architectures ranging from the original Pentium Processor of 1994 up to the Core 2 Duo based Pentium simply called the "Pentium". The Intel Pentium used to be Intel's flagship processor. Recently this position has been taken by the Core 2 Duo and Core i7. The Pentium now is reduced to a budget processor that offers lower performance but also lower cost.
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).
A generic "dual core" processor is any processor which has two separate processors on a single chip. This should not be confused with the Pentium Dual-Core, which was a brand of dual core processors which used the Pentium architecture on each core. The Core 2 Duo is also a specific processor from Intel. The Core 2 is a brand of microprocessors based on the Core architecture. The Core 2 Duo specifically refers to a dual core version of the Core 2 brand.
