On April 15, it was reported that Apple's recently released 2020 iPad Pro was equipped with A12Z Bionic chip. The name of A12Z Bionic is similar to that of A12X Bionic in 2018, and the performance improvement is limited, which makes people wonder whether these two chips are very similar.

TechInsights, a professional analysis organization, recently issued a report, which said that A12Z and A12X were found to have the same mold structure when closely observed, and they both had 8 GPU cores at the same location. The difference is that seven of the eight GPU cores of A12X have been enabled, while the better A12Z has enabled all eight cores. This practice is somewhat similar to that of AMD, which also occasionally has this "Sao operation".

The launch time of the new iPad Pro is about one and a half years away from that of the previous generation of products. The A12Z and A12X use the same TSMC 7nm process. The former GPU has an additional core that can work normally. The new chip is not worth Apple's naming "A13X", which is why it is called A12Z.

Although the 2018 iPad Pro also has 8 GPU cores, one of them has been disabled in the software, and users cannot really use it. It is worth mentioning that the chip yield in 2018 should not be as high as it is now, so the disabled GPU core may not be easy to use.
