The document discusses Intel's quad-core processors, which contain four processing cores on a single chip. This allows higher performance with lower power consumption compared to single-core chips. Quad-core processors are designed to improve performance for applications like workstations, servers, gaming, and datacenter virtualization while reducing total cost of ownership. An example application described is a 3D mapping software that combines topographical and satellite data to model natural disasters, which would benefit from a multi-core platform.

2. One constant in computing is that the world’s hunger for faster performance is never satisfied What are we really looking for? Superior Performance Energy Efficiency Ultimately Energy-Efficient Performance We have had Hyper-Threading (HT) Dual-Core and Core 2 Duo And now Quad-Core Road to Quad-Core Technology

3. What is Quad-Core? Four execution cores in one package Each core runs at a lower frequency Power normally given to a single core is divided among four cores Resulting in higher performance per watt of power consumed Performance = Frequency x Instructions/Clock Cycle Power = Dynamic Capacitance x Voltage 2 x Frequency Are designed to Plug into current motherboards Meet thermal and electrical specifications Reduce Total Cost of Ownership Increase Return on Investment Fabricated on 65nm Silicon Process Technology

4. Intel Core Micro-Architecture Intel Advanced Smart Cache L2 cache shared between 4 cores Dynamic usage (up to 100%) per core Intel Wide Dynamic Execution More instructions per clock cycle Each core can complete up to 4 full instructions simultaneously Intel Virtualization Technology Hardware assisted virtualization Fully-Buffered DIMM Technology High speed memory access Intel I/O Acceleration Technology Hardware assisted I/O Digital Thermal Sensor (DTS) Efficient processor and platform thermal control System fans spin only as fast as needed to cool the system Slower spinning fans generate less noise Features on an Intel Quad-Core Processor
