A multi-core design in which a single physical processor contains the core logic of more than one processor. Goal- enables a system to run more task simultaneously achieving greater overall performance
Hyper-threading or multicore?
Early PCs-capable of doing single task at a time. Later multi-threading tech., came into place. Intel’s multi-threading called Hyper-threading
Each core has its execution pipeline. No limitation for the number of cores that can be placed in a single chip. Two cores run at slower speeds and lower temperatures. But the combined throughput > single processor. The fundamental relationship b/w freq. and power can be used to multiply the no. of cores from 2 to 4, 8 and even higher
