Although ARM is a small company, but they are the core of the entire ARM processor camp, in addition to Apple, Qualcomm and other very few companies can develop their own ARM compatible architecture, MediaTek, Hass and most other companies will directly use the ARM's public Cortex-A architecture license.
Since the 64-bit era, ARM has released two architectures: Cortex-A57/A53, but only A53 has blossomed. The high-performance A57 core is only used by Samsung and Qualcomm in the mobile phone market, and is facing embarrassment of dystocia. To this end, ARM has introduced the A57's successor, the Cortex-A72 architecture, which boasts 3.5 times the performance of the A15 and a 75% reduction in power consumption.
The Cortex-A72 was first released in early 2015. It is also based on the ARMv8-A architecture and uses TSMC's 16nm FinFET manufacturing process. The Cortex-A72 can achieve performance on a chip alone, and can also be used with the Cortex-A53 processor and the ARMCoreLinkTM CCI cache. Even (CacheCoherenTInterconnect) constitutes ARMbig.LITTLETM configuration to further improve energy efficiency. With the same mobile device battery life limit, the Cortex-A72 offers 3.5x performance compared to Cortex-A15-based devices and 1.8x more performance than the Cortex-A57, demonstrating excellent overall performance. Efficiency. The Cortex-A72 is currently one of the most widely used processors based on ARMv8-A architecture processors. Its application markets include high-end smartphones, large-screen mobile devices, enterprise network devices, servers, wireless base stations, and digital televisions. .
The first is the infrastructure. The Cortex-A72 emphasizes not the number of heap execution units, but the overall enhancement. From instruction fetching to arbitration, branch prediction, and even the cache and Load/Store units, the Cortex-A72's components have been greatly enhanced, with the most up-to-date memory subsystems being up to 50%.
ARM said that at the same frequency, the Cortex-A72's single-cycle instruction throughput is 20%-60% better than the Cortex-A52, and if the same performance, the power consumption can be reduced by 40%-60%. In addition, the Cortex-A72 can also be paired with the Cortex-A53 to form a big.little size kernel.
This is followed by a comparison of power consumption. The same applies to the 28nm process. The Cortex-A72 consumes 50% less power than the Cortex-A15, and the power consumption is reduced by 75% if the 16nm process is used.
This is followed by performance predictions. Compared to the Cortex-A15 architecture built on a 28nm process and running at 1.6GHz, the Cortex-A72 processor running at 2.5GHz provides 3.5 times performance compared to the Cortex-A15 architecture running at 1.6GHz.
In the end, ARM moved out of Intel's 14nm Core M 5Y10C processor, resulting in a small loss of single-threaded performance and a multi-thread Cortex-A72 victory! Leading up to 1.6 times. The Cortex-A72's memory performance is faster than Core M. ARM also emphasized that in this case the Cortex-A72 processor consumes only 1W, while the Core M consumes 4W, and AMR wins again.
What is the performance of the ARM CortexA-72 processor? The Cortex A72 is based on the 64-bit ARMv8 design and is twice the computational speed of the current Cortex A57 architecture and 3.5 times faster than the Cortex A15. Compared to the technology Cortex-A72 five years ago, the computing performance even increased by 50 times. We compared the Cortex-A series of processors to find out.
From high to low can be roughly sorted: Cortex-A73 processor, Cortex-A72 processor, Cortex-A57 processor, Cortex-A53 processor, Cortex-A35 processor, Cortex-A32 processor, Cortex-A17 processing Processor, Cortex-A15 processor, Cortex-A7 processor, Cortex-A9 processor, Cortex-A8 processor, Cortex-A5 processor.
According to the above data, the Cortex-A-72 processor ranks second, and it seems that the performance is still leveraged.
Application of ARM CortexA-72 ProcessorThe Cortex-A72 is an ARM processor with excellent performance and is designed for a variety of devices that require high performance in an ARM low-power architecture.
Its target application market includes: high-end smart phones, large-screen mobile devices, enterprise network devices, servers, wireless base stations, and digital television.
