Cortex-A 72, Qualcomm'sSnapdragon 810And NVIDIATegra X1Current high-end model CPU cores adopted in "Cortex-A 57"This successor CPU core is the next-generation CPU core expected to be released as the" second generation ARMv8 architecture "in 2016.


According to the performance comparison released by ARM, Cortex-A 72 is the number of execution instructions per clock frequency compared with Cortex-A 57IPC (Instructions Per Cycle)Has improved from 20% to a maximum of 60%, but has succeeded in drastically reducing power consumption. Combine with Cortex-A 53Big.LittleIn the configuration, it says that it can reduce power consumption by 40% to 60% compared with Cortex-A 57.


The Cortex-A 72 has been redesigned the L2 cache, while the Cortex-A 57 is up to 2.5 GHz, whereas the Cortex-A 72 supports up to 2.7 GHz. Even with performance per core, we achieved performance improvement of 18% to 30%.


If Cortex - A 72 is released in 2016, smartphone performance is expected to further improve.


In addition, ARM is an Intel mobile processorCore M (5Y 10 C)Although performance of Cortex-A 72 is slightly inferior to performance per single thread, the performance in multithreading greatly exceeds Core M (5 Y 10 C), memory performance is up according to it, according to it And that. In particular, Core M (5Y10C) is 4 W while Cortex-A 72 is less than 1 W, the high watt performance stands out.


In Cortex - A 72, not only mobile terminals such as smartphones and tablets, but also server CPUs are targeted. The figure below compares the performance when 20 threads workloads are compared, the 20 core Cortex - A 72 is less than 30 W, 10 core Intel "Xeon-E 5 2660"It shows the performance equivalent to 105 W of W", which shows overwhelming power savings.
