There is one catch, though: the Zephyrus M only comes with GTX 1660Ti and RTX 2060 GPU variants, and higher-tier GPU won’t make it inside this frame. I’d reckon that’s mostly for two reasons: the cooling might not be able to handle a higher-tier GPU, and Asus will probably want to separate the Zephyrus lines, keeping the S at the top, with RTX 2070 (in the GX502, reviewed over here) and 2070/2080 Max-Q (in the GX531, reviewed here) graphics.
The article below tells you what to expect from the Zephyrus M GU502 series, how it compares to the Zephyrus S line and touches on some of the potential concerns that need to be vetted in a future review (which should be available in the following weeks), before concluding whether this can take on the Razer Blade 15, probably the most balanced option in this niche as of April 2019.
