The Intel Pentium 4 3.0 GHz processor is a single core processor, but if you'd like to upgrade to dual core, have a look at the Intel Pentium 4 531 3.0GHz Processor Upgrade RH008AV.
you don ´t answer the question you prick!
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.
A Pentium 3 Processor is found in many different systems and accomplishes many things. A Pentium processor is the name of the Intel company's central processing unit (CPU) hardware.
over 3.1 million
As many cores and threads that the processor has. The new Intel i7 will shows as 8 cores and Vista can use them all.
The Pentium III was a processor found in many computers, both desktop and laptop, in 1999 and early 2000s.
The Centrino Duo processor made by the company Intel has two cores. It is implied in the name "Duo" , which can be translated as "two", "double" or "twice".
There are version of Intel Pentium one through four as well as Intel Pentium Pro, Intel Pentium D, Intel Pentium M, Pentium (2009), and Pentium Duel Core.
The Socket 4 Pentium processor from the early 1990's had 273 pins the socket 5 had 320.
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.
It has 4 ALU units. A Pentium 4 has 2 ALU units. The Pentium D is like 2 P4's....sooo..... 2 cores x 2 ALU's each = 4

The basic diffreence is that in a mobile processor, they build it so that it uses as little power as possible, so that your battery lasts as long as possible. There are many ramifications to this, but that's the motivation.
