ARM company introduced the new 64-bit computing core Cortex-A72 and new graphics Mali-T880. The company also updated interface / controller (the north bridge) to version CCI-500. As for smartphones and tablets all this happiness will be available during 2016. This year, you'd expect the announcement of processors on the new ARM development of . The company reported that the license for the core Cortex-A72 and Mali-T880 graphics have received more than 10 companies, among which are called names HiSilicon, Rockchip and MediaTek.
New core use the same set of 64-bit instructions ARMv8-A. Currently there are no updates, whether new architecture to support the extended instruction set ARMv8.1-A, presented in December last year. By itself, ARM continues to develop the concept of combining the core of different productivity. As with previous decisions, the core generation Cortex-A72 can work in conjunction with the core of the previous generation (technology ARM big.LITTLE).
Cortex-A72 architecture is optimized for 16-nm process technology with the transition to the transistors FinFET. The maximum clock frequency of application solutions class smart are advised not higher than 2.5 GHz (architecture allows you to raise up to 3 GHz). According to ARM, the new ore 3.5 times faster than the Cortex-A15 cores 28 on process technology and in some cases twice as productive 20-nm cores Coretx-A57.
Processors Cortex-A72 cores may consist of a maximum of four cores. More four cores can be connected using the technology of ARM big.LITTLE. In general, smaller scale process technology and architectural changes promise to reduce consumption of the same tasks by up to 75% compared to the Cortex-A15 cores and to decrease consumption by another 40-60% in the case of a transition to mode big.LITTLE.
About the new Mali-T880 graphics can say the following. In the maximum configuration, Mali-T880 may consist of 16 video core. For the 16 nm process technology core clock frequency can reach 850MHz. Core support API OpenGL ES 1.1-3.1, OpenCL 1.1 and 1.2, and DirectX 11. In comparison with Mali-T760 on the same load capacity cores Mali-T880 is 1.8 times higher, and less consumption by up to 40%. The new core can easily display and record (encode) video stream with the quality of 4K at a rate of 120 frames per second. Supported codec HEVC.
Skipping new ability Northbridge CCI-500 on the memory bus has been increased by 30%, and the consumption is reduced to 12%. Related Products :
