ARM’s New CPU And GPU To Power Mobile VR in 2017

ARM, the company which designs processor architectures which are used in virtually all the mobile devices available in the market, has used Computex Taipei 2016 in order to announce new products which it expects to see deployed in the higher-end smartphones in the upcoming year. The cortex –A73 CPU and Mali-G71 GPU are designed to increase performance as well as power efficiency, with a particular view to supporting mobile VR.

ARM informs us that the Mali line of GPU are among the most frequently and widely used across the globe, with over 750 million shipped in 2015. The Mali-G71 is among the first to use the company’s third-generation architecture, which is known as Bifrost. The core allows for 50-percent higher graphics performance, 20 percent better power efficiency, and 40 percent more performance per square mm over ARM’s previous Mali GPU. As per The Verge, the scaling is up to shader core, and the company states that the Mali- G 71 can match discrete laptop GPU’s like Nvidia’s GTX 940m. It has also been designed around specific issues thrown up by VR, supporting features such as 4K resolution, a 120Hz refresh rate and 4ms graphics pipeline latency.
As for the CPU’s, ARM is announcing the new Cortex-A73 core, which goes on to prioritize the power efficiency. It is around 30 percent more efficient compared to the earlier Cortex – A72, while offering around 1.3 times the level of peak performance, however ARM has also gone on to focus on sustained usage – the A73 offers twice the performance within its power budget.
Although ARM architecture dominates the mobile landscape, there are good chances that you will not be able to see these specific products in the flagship phone in 2017. ARM licenses its architecture and cores separately, which means that the companies are free to pick and choose what they like. Apple, for example, licenses ARM architecture; however, it now designs its own custom CPU cores which is known as Twister in the latest A9 processor which uses Power VR GPU solutions form Imagination Technologies. Meanwhile, Samsung designs some Exynos processor core but it uses it alongside ARM’s Cortex and Mali GPU I its internationals Galaxy S7. The Qualcomm reverted to its own custom Kryo CPU cores in the Snapdragon 820 — which powers the US Galaxy S7 — after using Cortex in the 810.
ARM expects the chips to move into production by the end of the year and it will make its appearance in shipping devices by early 2017.
