The Pentium III provided two execution units on one chip. This is sort of like two cores, but with important limitations. The issue is that the two execution units share the same high level bus interface. This means that the two threads considered for simultaneous dispatch must be in the same address space, i.e. in the same process. This is wonderful for programs designed to use multi-threading, but does nothing for two programs running as two different processes. The Dual Core architecture moved the dividing line down further into the bus interface. Now the OS can dispatch both execution units, even if they are running in different address spaces.
Its XEON because of its high front side buss and higher floating point. Also the die is considerable smaller than celeron to give more performance to heat ratio.
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 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.
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.
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.
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.
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.
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.
