功耗和噪音真是悲劇

文中一段:
Unfortunately this performance increase comes at the cost of increased power draw. It seems that AMD has picked the highest clocking chips and gave them some extra voltage to ensure things are stable. As a result we see significantly higher power draw when gaming. Performance per Watt is also much worse, even with the 10% performance increase taken into account. The jump in power consumption also directly affects temperature and noise. While temperatures are just ok with 83°C under load, noise is completely unacceptable. The card runs at 51 dBA - one of the noisiest cards ever tested, noisier than NVIDIA's GeForce GTX 480.
