Number of machines that one SEPM 14 with SQL database can support

Is it true that one SEPM 14 with SQL database now can support up to 18 000 machines? This is what I can see in this article:

But so far with SEPM 12 it was written that it can support up to 45 000 - 50 000 machines:

https://support.symantec.com/en_US/article.HOWTO81147.html - this article says "Connect up to 45,000 to 50,000 clients to a management server" 

And this old forum thread even says "In SEPM 12.1 with SQL database supports upto 80,000 clients per SEPM" - https://www.symantec.com/connect/forums/how-many-clients-1-sepm
