Geekbench's benchmark result over the past week has surfaced Slashleaks for an unpublished Mac code-named AAPJ140K1.1, powered by an eighth-generation dual-core Core i7 processor with a base clock of 1.8 GHz is driven. The exact model is not listed, but the logic board has the same part number as the new MacBook Air.
As further proof, the benchmark result lists 1
The apparent MacBook Air with Core i7 chip has a multi-core rating of 8,553 on Geekbench, making it about 8.5 percent faster than the average multi-core. Core score would be the existing option with a Core i5.
Geekbench founder John Poole told MacRumors that nothing about the benchmark score seems fake to him, although this possibility can not be completely ruled out. If it really is, however, this indicates that there is a MacBook Air from 2018 with a Core i7 in Apple, but apparently not released to the public.
It can be assumed that Apple prototypes several different versions of its products and does not see all the light of day. Why the MacBook Air was not released with a Core i7, one can only guess – maybe it was too hot, or Apple opted for the dual-core Core i7 a MacBook Pro option or something else.
If Apple wants to add the Core i7 as an upgrade option for the new MacBook Air it's hard to imagine that this will happen soon, assuming the notebook has just been updated. However, Apple has historically ramped up the MacBook Air processor in the mid-product cycle, so the move takes precedence.
All in all, there may be a new MacBook Air with a Core i7 in the wild, which Apple decides not to ship or ship at a later date.
