    Neural Engine wasn’t mentioned by Apple’s press release and ML Compute documentation, and the API doesn’t really have a way to select Neural Engine as the executor. This appears to be an abstraction around both Accelerate (CPU) and Metal Performance Shaders (GPU), presumably with some adaptive logic in choosing executors.

    Buried inside Bloomberg's rumor about ARM Mac chips is a tidbit about an upcoming iPad Pro:
    I think a lot of people assume that the chip in the next iPad Pro, which has universally been given the placeholder of "A14X," is either the same chip as the M1 or has an extremely similar configuration.

    It wouldn't make much sense to tape out another 5nm chip with a similar configuration. The iPad Pro volumes are not large enough to justify this (one of the reasons we saw the update earlier this year use the 12Z instead of a new A13X). I'd wager it'll be the M1 with 7 GPU cores enabled, and possibly clocked slightly lower for thermal reasons, given the smaller size of the ipad vs macbook.

    M1 and A14 probably use the same cores?

    Also interesting that this new iPad Pro has "up to" 16 GB RAM. Would be the first time they have separate SKUs or configurations for RAM on the same iPad model.

    The other things of note are Thunderbolt and XDR display on the 12.9 inch model, capable of 1600 nits peak. That is the mini-LED display.

    8 GB RAM for iPad Pro with upto 512 GB, 16 GB for 1/2 TB. And actually not, the iPad Pro (2018) had different RAM sizes depending on storage, iPad - Wikipedia
