This guy really doesn't get the point - he's testing an embedded part with 16GB RAM against an overclocked desktop part with 64GB RAM (and a load of the benchmarks are garbage collected so the extra RAM is significant). Its also the case that none of these benchmarks are Apple specific - users buying a Mac Mini for development are likely to be developing in Swift for which the M1 has special optimizations. Need to wait for Apple to release a part for an iMac or MacBook Pro to inform his conclusion that x86_64 is going to be able to outperform Apple's ARM chips going forward.
