This would be true if the video showed 1000 instances of the most exquisite waves or softube plugins. As I said in another thread about the same thing, any daw ill be able to run A LOT of stock plugins with a good cpu, regardless it being an intel or a mac or an AMD. Come on, I ran test projects with 400 stereo tracks with the full reason SSL devices on, which are equivalent to using the 3 or 4 inserts they are talking about there... A test I did with Cubase and East west loaded 200 instances of multi sampled violins. A tad more with Reaper. A tad less with Reason 10.4.
All these tests with an Intel i7 4790k! That's... a 7-year-old CPU. And i can run 50 to 100 tracks on that CPU and reason 12 today. Not too shabby - and tbh it's the mastering effect chan that takes my cpu down instead of the rest of the 300 plugins! Just to put things into perspective.
So again... If we compare stuff, let's compare a bit more scientifically or this is a marketing fanboy mess.
So you have to look at these types of videos with a grain of salt because they can be "made". Chances are, if you test the same DAW, with the same Plugins, the delta is not as big (and tbh they are not comparing anything to anything. What I mean is, 1000 plugins means absolutely nothing if you don't compare and don't look at all variables) for a similarly spec'ed pc and cpu. It's true the different cpu architecture puts some difficulty, and now you have 2 different aspects at this - not only you have a new arch that Intel is also doing in the new 12th gen but Intel's and AMD's are still CISC and Mac's turned again to RISC. That being said, I doubt the RISC instruction set is that amazing - It's just a matter of time that Intel's get on the same level. In the end, I guess if the compilers are good, it will always come down to metal.
As for the Windows vs OSX rant... Man with reason, cubase, ableton, reaper or any other daw that works both with windows and mac, once you stick your head on the daw, does it really matter? I like windows but i'd work ok with OSX or linux (amof, i have more experience with linux than with OSX) so i guess it's just a matter of getting used to the OS. As long as it's a graphical environment with apps and windows, come on...
And stability is now NOT an issue. Windows 7, 8.1 and 10 have been super stable (I've been working with windows since 1996).
