What are the differences between an Intel Core 2 Duo and an Intel Pentium Dual-Core?

Answer 1

Intel Pentium Dual-Cores are identical in architecture to Intel Core 2 Duos. The differences are:

• Intel Core 2 Duos have a larger amount of L2 cache. In certain applications, a larger L2 cache can provide a major boost in performance.
• Intel Pentium Dual-Cores lack some features that the Intel Core 2 Duo includes, such as support for Intel VT-x (used for virtualization) and TXT (Trusted Execution technology).
• As of September, 2009, the fastest FSB supported by the Pentium Dual-Core line is 1066 MT/s. The fastest Intel Core 2 Duos support an FSB of 1333 MT/s.

Answer 2

The Intel Dual Core processor has two distinct processor cores inside one chip. AMD's X2 and Opterons (Denmark, Italy, Egypt, Sta Rosa and Sta Ana cores), Intel's Pentium D, Pentium EE, Core Duo, Core 2 Duo (Conroe, Allendale) and Xeon (Paxville, Tulsa, Conroe, Dempsey and Woodcrest cores) are ALL DUAL CORES.

Core2 Duo is specifically a new technology, high performance processor that does more per clock cycle and at lower wattage. Cheapest version= Pentium E2140 and E2160.

Still cheap but better= E4300, E4400, E4500 (Allendale)

Fast Core2 Duo = E6xxx series

Awesome = Core2 Extreme X6800

Answer 3

The main difference between an Intel Core 2 Duo and an Intel Pentium Dual-Core is that the Core 2 Duo features a 45 nm process and the Intel Pentium Dual-Core a 65 nm process. Both however feature two cores mounted on the same die.

Answer 4

Referring to the Wikipedia article on Intel Conroe edition processors: http://en.wikipedia.org/wiki/Intel_Core_2 "... the only major difference between the regular Core 2 Duo and Core 2 Extreme is the clock speed and unlocked multiplier, usual advantages of the "Extreme Edition." The unlocked upward multiplier is of use to enthusiasts as it allows the user to set the clockspeed higher than shipping frequency without modifying the FSB unlike mainstream Core 2 Duo models which are downward unlocked only." Basically if you are a PC enthusiast who wants to get maximum mileage out of your processor by overclocking it, you should consider getting the Core 2 Extreme which supports those things. Unless you intend to overclock however, it's not worth it because the extreme editions cost typically twice as much as the regular edition Core 2 Quad processors.

Answer 5

a lot! Pentium III probs bout 1.5GHz max, core 2 duo 3.2GHz max. Each core works on a different task or the same one. faster and more core is the key.

Answer 6

core 2 duo is more efficient, more cooler (colder), better architecture, more cache and overall better performance.
