The first Pentium Is required a voltage of 5 volts.
There were a few laptops that used Pentium 4s. However, Pentium 4s generated too much heat and drew too much power for them to be practical.
A Pentium 4 processor is more advanced because it is faster and able to do much more complex calculations. It will, however, be superseded by a more advanced processor eventually.
Much faster. I cannot say exactly how much faster is it, but at least 5-6 times.
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.
Possibly. "Celeron" doesn't refer to any particular processor. They are cost-reduced versions of the Intel Pentium II, Pentium III, Pentium 4, Pentium M, and Core 2 Duo. Assuming that your Celeron is based on a processor that is faster than the Pentium III, you shouldn't have any problems. If yours is based on the Pentium III, check the clock speed. A 1.2 GHz Celeron, for instance, is probably fast enough for a game that requires a 1 GHz Pentium III.Other factors, such as the graphics card of your system, may also be important.
It depends, but usually Intel is better. Older AMD processors (compared against the early Pentium 4) were much faster, however.
Processor: Intel Pentium 4 1.3 GHz or AMD Athlon XP 1500
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.
No. The Intel Core 2 Duo is much faster than the older Pentium 4.
It depends on your applications, but a Celeron D won't be all that much slower and will provide excellent value.
The "max operating temperature" of the original Pentium is 85°C. While it could theoretically run hotter than this, if it got much hotter, it would malfunction, and likely destroy both itself and the 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.
