Both. The Intel Core Duo was a 32-bit dual-core processor. The Intel Core 2 Duo is a 64-bit processor.
Athlon 64 X2 Dual Core Processor also the AMD Opteron uses dual-core technology (designed for high end servers and workstations)
A processor that uses Hyper-Threading Technology and dual-core processing and is designed to be used on servers and high-end workstations in a corporate environment
What term does AMD use to describe the processor technology that uses a 64 - bit instruction set with 32 - bit internal core processing
Yes it can. I've done it plenty of times (my computer uses a 1.8GHz dual-core). I've played UT2004 and Need for Speed Most Wanted fine on it. Mind you, if your computer has a 1.6GHz processor, increase the RAM to the maximum supported, it really helps.
A dual core laptop is a laptop that uses a processor that has two cores. Having two cores allows a laptop to perform more powerful functions and speed than if it had a single core.
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.

Pentium MMX and AMD K6 both use dual voltage. The lower supply voltage is used for the core and the higher voltage is used to power the I/O pins.
Pentium 4 uses Hyper-Threading, which is like a dual core, but isn't. A Dual-Core consists of 2(two) logical cores.
