Sees Heterogeneous System Architecture (HSA) improvements as key to achieving target “25x20”
Advanced Micro Devices earlier this year got slapped with a shareholder class action lawsuit for allegedly overstating the sales prospects of its first generation Llano APUs (Accelerated Processing Units) — chips that house the GPU and CPU on the same die —between October 27, 2011 and October 18, 2012. However, the company, which is confident that it did not commit any violations of Federal Securities Laws in making those statements, does not plan to abandon the practice of making positive statements about the future of its APUs anytime soon. The company is now saying its APUs could end up becoming 25x more power efficient than they currently are by 2020.
What’s a watt? Depends how you measure it. Electrical engineers agree that watts equals volts times amps, but they start disagreeing when measuring the power dissipation of a microprocessor. Power consumption varies with the software workload, which can be anything from a program’s idle loop to a high-frame-rate videogame.
