Just yesterday, ARM company has extended the data on the comparative performance of the core Cortex-A53/A57 and Cortex-A7/A15. Core replaced Cortex-A53/A57 and Cortex-A7/A15. They support 64-bit computing and have a number of other improvements.
As you can see in the chart, in the case of load core ARM Cortex-A53 cores are faster ARM Cortex-A7 approximately 50% for solutions at the same process technology (28 nm) on 32-bit programs. In case of cores ARM Cortex-A53 using 20/16FinFET performance gap may grow almost twice. We have no doubt that ARM company report ideal image. However, more than likely that the new 20-nm or 16-nm solutions easily bypass 50% performance old 28nm SoC. At the same time, due to the increased performance, energy efficiency of new core grow uniquely. At a minimum, the application will run faster and thus, processors will spend more time in idle mode.
As for the comparison cores ARM Cortex-A15 and Cortex-A57, then the ratio of performance they have approximately the same as that between the younger generations of both core .
Finally, ARM introduced the testing schedule of new and old core in Geekbench benchmark 3. This test is interesting because it gives the opportunity to compare the core in 32-bit mode and 64-bit. New core on the same frequency in 32-bit mode ahead of the old by from 15% to 30%. Related Products :
