ARM announces Cortex A72 core for smartphone processors




British ARM has announced the Cortex-A72 core smartphone processors. Processor manufacturers should make Cortex A72 CPUs on a 16nm FinFET-process. Besides the new core ARM also comes with a new GPU.

ARM Cortex A72 The Cortex A72 will be the successor of the Cortex A57 core serving in include the Snapdragon 810 Qualcomm and recent Exynos processor from Samsung. Those processors probably end up in all high-end smartphones from this spring, like the HTC One M9 and Samsung Galaxy S6. The A72 is for smartphones released in 2016.

ARM claims that the Cortex A72 is 1.9 times faster than A57, while he would be about 45 percent more efficient at the same load. This gain is largely attributable to the manufacture on TSMC’s 16nm FinFET-process. Now comes of that economy in practice often failed to materialize because processor makers and smartphone manufacturers often choose to increase the clock speed in order to make smartphones faster than predecessors.

The British company says Cortex A72 ‘sustained performance’ offers at 2.5GHz, while manufacturers him to higher clocks for short peaks in performance. ARM believes A72, like its predecessor the best it can be used in a big.LITTLE configuration with some economical processor cores, such as Cortex A53. That’s what happened with current socs for smartphones. The Cortex A72 can run on 64bit and is based on the ARMv8a architecture.

The extent to which manufacturers will really use the Cortex A72, is still unclear. Qualcomm used in recent years often its own micro-architecture on 32bit and 64bit would work on a successor to its core Krait. Samsung also would have according to unconfirmed rumors plans in that direction, while Apple several years to work only with their own cores. Huawei invariably fit while ARM’s designs.

Beside the A72 ARM also presented a new GPU, the Mali-T880. This would be the most powerful GPU from the lineup of ARM are so far. Also made by TSMC in 16nm. The T880 offers 1.8 times the performance and consumed in the same tax 40 percent less energy than today’s Mali-T760.
