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 newer processor will not use the same motherboard.
The D is a reference to being "dual-cored," or having more than one processor core. Although it uses the same concept as the Pentium Dual-Core, they should not be confused. The Pentium Dual-Core is much faster, more efficient, and cooler-running than the Pentium D.
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.
No. Pentium 3 and Pentium 4 stand too apart from each other. For upgrading any processor on the same motherboard, they need to be in same socket type and the external interfaces should be compatible. P3 is a very old single core chip and is a lot different from latest dual core processors, so this upgrade is not possible.
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.
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.
This depends on what type of A-Series you are talking about, but the i3 is better than the Pentium Dual Core although they are based on the same microarchitecture.
Pentium D is just the name Intel gave to that particular line of processors. Dual core technology means that the single chip has two processors on it. This makes it capable of executing two commands at the same time. Do not confuse Pentium D dual core with the newer Core 2 Duo. They are vastly different chips. The Core 2 Duo (and the Core 2 Quad) core chips are greatly improved over the Pentium D chips. Pentium D is just the name Intel gave to that particular line of processors.

Two things here: 1. No, a dual-core processor does not "count" as 2x the clock speed. If you disable one of the cores on a dual-core processor, the chips will still run at the same clockspeed, and will perform about the same on single-threaded applications, like most games. 2. Most processors these days are dual-core, and they are more efficient and faster than older single-core chips, even though they have a lower clockspeed. Your probably requires a 3 GHz Pentium 4, and you have a newer and faster processor than that.
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.
They are approximately the same at the same frequency.
It´s not update, it´s downdate! Over all, I think these two processors don´t have the same socket!
