Since the system's launch, production costs have been reduced significantly as a result of phasing out the Emotion Engine chip and falling hardware costs. The cost of manufacturing Cell microprocessors has fallen dramatically as a result of moving to the 65 nm production process, and Blu-ray Disc diodes have become cheaper to manufacture. As of January 2008, each unit cost around $400 to manufacture; by August 2009, Sony had reduced costs by a total of 70%, meaning it only costs Sony around $240 per unit.
Along with a drop in the cost of hardware, PS3 has gotten cheaper to make because what chip was phased out? What's the name of the microprocessor produced by the 65 nm process? What specific component of Blu-Ray disc have also gotten less expensive to make? As of Summer 2009, what was the cost to Sony to make a PS3? The August 2009 cost is a result of what percentage decrease in production cost?
