While CPU manufacturers have already started defining power consumption and performance per watt as the new reference standards for comparing/developing new CPU models; so far, graphic cards manufacturers did not really feel concern about such parameters and every new GPUs were racing towards the same goal: be the fastest irrespective to the power consumption.
Things might change in a near future, if one considers the screen capture related to the future presentation of the forthcoming AMD/ATI Radeon HD4770.
AMD/ATI have used performance per watt as one of the marketing parameters. They compare the forthcoming entry level model Radeon HD 4770 with the aging NVidia GeForce 9800 GT. According to their figures, the Radeon is almost 3 fold faster per watt. AMD takes advantage of an exclusive 40 nm engraving process, even thinner than the one currently used by Intel.
AMD most likely decided to apply this new engraving process to entry-level GPU as their architecture is usually not as complex as the high-end models. However, AMD will most likely transfer it to all other models, and the benefit of thin engraving could rather be used for high-end GPU to push core frequency higher, while controlling heat release. In other words, power consumption might not be the future marketing parameter of 40 nm engraved future flagship GPU from AMD. Especially, if one considers the growing importance of GPGPU, synonym of growing needs for raw power. This could be associated to greener behavior if the power management of the GPU is really improved to switch off unused cores as today in CPUs.

Patent requests from Apple continue to provide clues as to where the company may take its iPhone interface in the coming years, such as a new filing which depicts a version of the handset with a front-facing video camera and a software interface capable of adjusting itself for more precise interaction when the user carrying the phone is in motion.
