Those numbers are actually quite good. Microsoft surface pro X, that runs on ARM natively(no x86 to ARM translation) has score: 720 / 2800. So apple A12Z runs faster with translation from x86 to arm than microsoft SQ1 ARM chip. That is remarkable. Also, if I compare my macbook pro 15' 2018 with Intel Core i7-8750H it has 961 / 4760 (with turbo and with a lot of noise and heat), with turbo disabled (so it runs at 2.2GHz) score is 573 / 3700 . Considering that mac chips will not have 7W limit iPad has because there is no active cooling, and that TSMC will produce it at 5nm, this cpus are going to destroy everything currently on market.
