We’ve talked a lot here about the A13 Bionic, the chip that equips iPhones for 2019. Apple itself sells the processor as being 20% faster than its predecessor, the A12 Bionic, and Apple engineers said the focus on its engineering is energy efficiency. But how do these promises translate into real life?
It was exactly what the AnandTech tried to find out. In in-depth testing of the chip, the site found that Apple’s claims are real: on average, the performance of the new CPU is 20% higher compared to the A12 Bionic. However, one detail has to be considered: to achieve this performance, Apple increased the A13’s energy consumption; at certain times, the chip can use up to 1W more energy than its predecessor.
According to the analysis, this behavior is a double-edged sword: while giving superior performance to the new chip, the extra energy consumption may mean that the new iPhones will be more sensitive to temperature increases and susceptible to the infamous throttling (when the system purposely decreases the performance of the processor to control the temperature of the device). Still, in general, the AnandTech determined that the A13 is about 30% more efficient, energetically speaking, in relation to its predecessor – in general terms, that is.
Returning to performance, the analysis found that the A13 performs similarly to the “best desktop chips from AMD and Intel” – at least based on one of benchmarks used by the website, SPECint2006. In the Speedometer 2.0, the new Apple chip reached scores that represent more than double the smartphones equipped with the Snapdragon 855+, the most advanced processor currently from Qualcomm.
If in process the A13 Bionic is already a good advance, in terms of graphics performance the new chip is quite a leap: according to the analysis, the processors of the iPhones 11/11 Pro [Max] they stand out especially in the ability to maintain maximum performance for a longer time – the website remembers the case of the A12, which could only keep graphics at maximum performance for 2-3 minutes. Fortunately, this does not happen here, which shows a good job by the engineering team in the dispersion of heat.
