New amd polaris 2.0 graphics cards will be 50% more energy efficient
Table of contents:
AMD has always talked about Polaris as a very efficient graphics architecture with energy consumption, something that has been quite eclipsed with the arrival of Pascal from Nvidia, which has been much superior in this regard. AMD is preparing a second generation of graphics cards based on the AMD Polaris 2.0 10 and Polaris 2.0 11 silicons with up to 50% higher energy efficiency, so we would be facing a significant reduction in energy consumption.
AMD Polaris 2.0 will be much more efficient
The improvement in the efficiency of Polaris 2.0 will be possible thanks to the maturation of the manufacturing process at 14 nm Samsung's FinFET and the improvements introduced by AMD in the software. These new graphics cards will be easily recognizable by including the Radeon's RX 4X5 and Radeon's 4X5 nomenclature. Thus all the cards that end their numbering in a 5 will be revisions of the originals much more efficient with the use of energy. AMD will not take advantage of the improvement in efficiency to substantially increase its performance, it will focus on offering products with much lower energy consumption, the new Radeon RX 485 will have a TDP of only 95W compared to 150W from the current RX 480.
The new AMD Polaris 2.0 graphics cards would be the AMD Radeon 445, Radeon 455, Radeon 465, Radeon RX 455, RX 465, RX 475 and RX 485. From there we would see the most powerful cards based on the new AMD Vega graphics architecture that will arrive during the first half of 2017 and promise to fight with the best of Pascal thanks to the inclusion of the advanced HBM2 memory with enormous bandwidth.

Intel's new processors will be slower and more efficient
In this 2016 and 2017 we will see the new Intel processors with slower frequencies but much more energy-efficient and performance efficient.
Amd works on a new, more powerful and efficient polaris core
AMD would be working on the development of a new graphics core based on the Polaris architecture with higher performance and energy efficiency.
Ubuntu 18.10 will be more efficient with the use of energy
Canonical is working to offer better battery life on UBuntu 18.10, something that is one of the weak points of Linux distributions.
