AnandTech announced its depth review about the iPhone 11 lineup. Together with fine points analyzing the processor and graphics performance of Apple’s latest A13 Bionic chip over A12 Bionic chip.
Outsetting with the CPU performance, AnandTech found out the A13 Bionic Chip to be quite faster than A12 Bionic Chip. Almost A13 Bionic chip is 20% faster than the A12 Bionic chip. Although Apple claims A13 chip to be 30% faster than A12 Chip. The sites claim that Apple had to increase the CPU cores peak power consumption:
In virtually all of the SPECint2006 tests, Apple has gone and increased the peak power draw of the A13 SoC. In many cases we’re almost 1W above the A12. Here at peak performance it seems the power increase was greater than the performance increase. And that’s why in almost all workloads the A13 ends up as less efficient than the A12.
AnandTech reviews are highly regarded for their CPUs and GPUs coverage components. AnandTech was more impressed with the GPU performance. The iPhone 11 pro had 50 to 60 percent higher performance than the iPhone XS based on the graphics benchmark:
Where the new chip really shines and exceeds Apple’s own marketing claims is in the sustained performance and efficiency of the new GPU. Particularly the iPhone 11 Pro models were able to showcase much improved long-term performance results, all while keeping thermals in check. The short version of it is that Apple has been able to knock it out of the park, delivering performance increases that we hadn’t expected in what’s essentially a mid-generation refresh on the chip manufacturing side of matters.
While talking about the A13 Chip performance, AnandTech believes high power drawer. High Power drawer results in being more sensitive to temperatures and prone to throttling. In terms of all the performance, Apple with A13 Chip is almost double than the best non-apple chip.
