They are acting like they are getting paid by Intel for advertising? Oh wait……This will be the last time I respond to you before blocking both of you, but no I didn't experience any slowdown when I tried to torture test it and open over 50 tabs. I tried opening other apps and doing other tasks at the same time and had no lag or any problems with the system whatsoever. Haven't experienced any issues with app compatibility or software issues in general.
It's consistently blown away my old i9 MBP while using a fraction of the power. I don't see anyone else complaining about the speed of these machines other than you two. Even hardcore PC users have been commenting on how happy they are seeing Apple producing more "pro" machines with these new computers and I think the whole industry in moving in an exciting direction with Apple silicon providing some real competition (and Intel coming back into it with Alder). Hopefully Intel GPU's can also mix up the market a bit.
Happy trolling you two, hopefully you have better luck with your next endeavor as you've definitely convinced nobody here!
