Some hackers that go by the username Longhorn on Twitter have revealed that the upcoming Apple A12 and A12X chipsets possess the part numbers T8020 and T8027 and will have a completely different CPU codename compared to the previous generation.

Before this, Apple processor’s codenames used to be synonymous with the wind. For instance, the A11 Bionic was codenamed Monsoon, A10 Fusion was codenamed Zephyr, while A9 was called Hurricane. Vortex refers to a whirlwind and scientifically, it is less likely to happen than monsoons and hurricanes. Is that indicative of the fact that the performance of the A12 would be limited or would it be able to produce benchmarking numbers beyond the comprehension of Apple’s competitors.
