I have a 500 page book with about 1500 equations and about 500 figures and typesetting takes about 3 seconds on the M1 and about twice that on the Intel machine. I am guessing that the time limiting task on your machines is not typesetting but something else. </div><div class=""><br class=""></div><div class="">Knuth acknowledges that TeX will not benefit from more than one core (the famous interview ~2010). I have seen a slew of benchmarks of the M1 Max vs the M1 Pro and the only place where it makes a difference is in tasks which can take advantage of the GPU. Of course, TeX is not in that category, but apps which do video editing and some scientific apps using the Apple replacement for OpenCL are. </div><div class=""><br class=""></div><div class="">A developer of a popular iOS app (Marco Arment) has tested the Xcode compile time on an M1 Max with 64 GB of Ram and an M1 Pro with 16 GB and it took exactly the same time on both machines (19 sec, vs 30 sec on an M1 in a Mac Mini). </div><div class=""><br class=""></div><div class="">I doubt very much that there will be any difference in typesetting speed for any of the current M1-based machines. </div><div class=""><br class=""></div></div></div></div></div></blockquote></div><div class=""><br class=""></div>On my Intel CPU iMac, I just retimed with no other apps running, including no real-time antivirus, and the complete PDFLATEXMK engine run through TeXShop is down to under 4 minutes.<div class=""><br class=""></div><div class="">The preamble is complicated and loads many packages.
