The difference between 2.66 dual core processor, and 64-bit dual core processor, is really two different processor specifications. 2.66 is actually 2.66Ghz, which is the clock speed of the processor. The clock speed tells you how many times the processor can execute instructions per second. A dual core processor is a processor with two cores on one die. This can be thought of as having two processors in one. The bit specification of a processor tells you how many binary instructions a processor can execute per clock cycle. Most processors today are 32-bit (32 binary instructions per clock cycle) or 64-bit (64 binary instructions per clock cycle). More RAM can be used with a 64-bit processor. A 32-bit processor is limited to addressing 4 Gigabytes of RAM, while a 64-bit process can address (theoretically) 16 Exabytes of RAM.

difference between dual core and core i3
Core 2 duo is dual core. And before that was core duo which was dual core too...
quad core has 4 cores a dual core has 2 cores
Over the years I have found that computers with 64bit dual or quad core CPU's and a 64bit operating system is best.
There is no difference between dual core and core 2 duo. Intel just name its recent family of dual core processors as "core 2 duo". Both (core 2 duo and dual core) works in same fashion.
A dual core processor has two processing cores, whereas a quad core has four.
the difference is core 2 duo gives more cooler temperature and supports more features than dual core processors
Pentium 4 uses Hyper-Threading, which is like a dual core, but isn't. A Dual-Core consists of 2(two) logical cores.
There is no technological difference but the only difference should be how it is phrased
Dual core is the property of having two cores in a single CPU. Core2Duo is an Intel CPU that has two cores.
dual core processors allow for twice as much data processing thus making computer much faster and stable.
