A year after introducing dual core to the world, Intel showed off quad core microprocessors with the Xeon 5300 line, which was used primarily for workstations and servers. Fast forward to 2011, and quad core processors are standard in mid-level desktop and laptop PCs thanks to Intel’s i3/i5/i7 Sandy Bridge architecture. Even eight core microprocessors are pretty routine (AMD’s FX line). And 16 core chips are not unheard of in enterprise workstations. Of course, more cores doesn’t always translate into more power and performance. Microprocessor value and improvement in the future may be measured by how well-threaded a given piece of software is to a particular chip and its multiple cores.
