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.
There is no "Pentium R" processor. Knowing this, the biggest difference is that the Pentium III exists and the other does not.
Nothing, a Pentium Processor, or any other processor for that matter, is merely a brand name for different microprocessors.
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 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.
pentium 4 more faster
4004 8008 8086 and series go on 80286 80386 80486 Pentium 1 Pentium 2 Pentium 3 Pentium 4 Dual core Core 2 duo Core 2 Quad Upto CoreI7 So basically in a long time period Pentium 4 is an improvement on 8085 and basically today micro code of all these processor is of 8085
On the Pentium II, the L2 cache is integrated into the processor packaging, rather than on the motherboard. This allows the L2 to be accessed much faster, and improving overall performance.
Centrino = better perfomance, less heat and less power consumption. The centrino is based on the newer Intel Conroe architecture.
The Dell Precision 410 workstation was equipped with either a Pentium II or a Pentium III processor, at a speed between 350 and 700 MHz.
If you are actually able to see the processor die, you should be able to read the text written on the top of the processor.
