What is core capacity of processor



There are also "dual-core" marketed CPUs based on "core 2 duo", but those are low-performance parts (think Celerons)

In other words, "dual-core" is a description (2 cores, can be used for all CPUs, wether Intel or AMD), while "core 2 duo" is a name (product name, used only by Intel).


All Core2duos are dual-core, but not all dual-cores are core2duo.
