From 22 to 26 February will be held the annual conference ISSCC 2015. This event is traditionally accepted to talk about the company's achievements in creating computing architectures. Report on AMD's processor architecture Carrizo is expected on 23 February.
The main focus in creating products generation Carrizo was on the increase of energy efficiency. The core computing power grow barely more than 5%, but Intel is also not consistent boasts a large increase in productivity. But energy efficiency at this stage, Intel and AMD are making somewhat different ways. Intel is betting on the improvement of process technology and vertical transistors, and AMD optimizes the design of architecture, based on the new library high density . However, here thanks to GlobalFoundries , which offered a better variety of 28-nm process technology.
In comparison to the number of transistors APU Kaveri composed APU Carrizo increased by 29% to 3.1 billion. Pieces. At the same chip area decreased by 23% and consumption will decrease by as much as 40%. The number of stream processors will not change and will be 512 pieces. But operations for transcoding video streams using H.265 format accelerated 3.5 times background for video core consumption reduction of 20%. It can be expected that in this way will increase the battery life of the new AMD platform, and (or) the overall graphics performance.
Carrizo processors become more energy efficient also due to more accurately track the temperature in different parts of the crystal. In the crystal structure of the processor is added 10 tracking sensors for real-time consumption values and - the current and voltage as well as frequency. The processor can more accurately allocate internal resources without fear of overheating cores or graphics core. Finally, AMD has introduced a new state of inactivity or S0i3, when the processor is able to continue to operate as separate units at the consumption level is only 50 mW.
