It's hard to forecast where this goes, though I still think Intel will provide the highest end chips for some years. Honestly depends on how fast Intel improves their products. Look up "Intel Core i9-9900K vs Apple A13 Bionic" on Gadget Versus. The i9 is scoring 19,775 vs the Bionic's 13,554. On one hand, it is stunning Intel can't do better. At the same time, professionals need every bit of performance they can muster. The future of hackintoshing might come down to two things: First, can Intel maintain enough margin over the chips Apple provides; Second, will Apple close the margin enough a performance hit for Intel processors requiring emulation, or the cost of maintaining MacOS to run on Intel chips, finally end any interest in Intel.
Even after watching Intel screw the pooch for years, it's hard to believe they aren't going to keep slugging away toward 5nm. If they get there before Apple's chip development closes the gap, Apple might have to keep Intel in the Pro series products.
