Apple A13 Bionic  yes  Apple  System level chip  (SoC), stay  iPhone 11  Used in series .  It's on  2019  Issued at the end of the year , Provide  6  Kernel , It includes  2  Personality can be core and  4  An energy efficiency kernel .  And previous  A12 Bionic  comparison ,A13  Of  CPU  Performance improved  20%, And the power consumption is reduced  40% .

Apple A13 Bionic  yes  Apple  System level chip  (SoC), stay  iPhone 11  Used in series .  It's on  2019  Issued at the end of the year , Provide  6  Kernel , It includes  2  Personality can be core and  4  An energy efficiency kernel .  And previous  A12 Bionic  comparison ,A13  Of  CPU  Performance improved  20%, And the power consumption is reduced  40% .

A13 Bionic  be based on  64 An architecture , The process technology is  7  Nanometer order of magnitude , There are  85  100 million transistors , Far more than Snapdragon 835  Of  30  Billion transistors and  Skylake  Desktop quad core  Soc  Of  17.5  100 million transistors .

To take the  A13 Bionic  Of  iPhone 11  Performance is far better than  iPhone XR, But their battery life is almost the same .

This is due to  A13 Bionic  By setting hundreds of voltage domains to reduce the voltage of the main components of the chip  idle  Power consumption in state , And setting hundreds of thousands of clock gating domains to disable unused logic gates .
