Not long ago, apple launched its 2020 iPad Pro product line, with major hardware changes in upgrading A12Z processors, six full-length back dual-shot LiDAR lidar scanners.
Apple's description of the a12z processor goes by a stroke, only mentioning that it is equipped with an 8-core GPU (a12x is 7-core). From the point of view of running score, the difference between the two is also small, which can not be touched for a while.
Today (14 April), Techinsights sunburned out internal perspectives of A12X and A12Z processors (new iPad Pro from model A2068) chips, which are identical only from the silicon wafer level.
This perspective also sat down to the previous analysis, that is, the difference between A12Z and A12X, And it's about opening the GPU core This is interesting, I do not know whether the follow-up folk god shot, unlock A12X hidden GPU, gorgeous transformation

Of course, external media analysis also shows that the reason why a12x shields a GPU may be related to the 7Nm yield of TSMC. After 18 months of continuous improvement, Apple was able to release the full blood a12z processor.
TI are also working on a deep analysis of A12Z processors, hoping to dig out more details, including stepping and transistor density.
