A12Z Bionic Chip in iPad Pro Allegedly a Renamed A12X With Extra GPU Core Enabled

Apple’s new 2020 iPad Professional fashions are geared up with an A12Z Bionic processor that is remarkably just like the A12X chip within the 2018 ‌iPad Professional‌ fashions, providing little in the way in which of efficiency enhancements.

The A12Z does, nonetheless, function an 8-core GPU whereas the A12X features a 7-core GPU, which units them aside, however new proof shared by NotebookCheck means that the A12Z Bionic is solely a renamed A12X chip with a latent GPU core enabled.

In response to NotebookCheck, teardown website TechInsights confirmed that the 2018 A12X chip bodily has Eight GPU cores and never the 7 GPU cores that Apple consists of in tech specs. One of many cores of the A12X is disabled.

The A12X and the A12Z seem like the identical bodily chip on the floor, with the identical variety of bodily CPU and GPU cores slightly, suggesting the A12Z is just not a brand new design. AnandTech has additionally speculated that the A12Z is a re-binned variant of the A12X.

There will be a number of speculative causes as to why Apple selected to do that. It isn’t unusual to see chip makers disabling bodily cores and enabling them in larger SKUs. As an example, the NVIDIA Titan RTX has all 4,608 CUDA cores enabled whereas the RTX 2080 Ti presents solely 4,352 cores regardless of each utilizing the TU102 GPU.

The opposite probably clarification is that Apple’s resolution to disable one GPU core within the A12X might have been deliberate. Enabling the latent core in an interim refresh just like the A12Z would save them from having to develop an A13X and as an alternative, immediately give attention to the (5 nm?) A14X that’s slated to debut with the 5G ‌iPad Professional‌ later this yr.

Sooner or later, TechInsights is planning to conduct a floorplan evaluation to find out for sure whether or not there are any variations between the A12X and the A12Z within the new ‌iPad Professional‌ fashions.

NotebookCheck speculates that Apple is saving an up to date chip design for future ‌iPad Professional‌ fashions, and there are certainly rumors of a second ‌iPad Professional‌ refresh this fall that would convey mini-LED shows and 5G connectivity.
