I'm looking into getting a Razer Blade 15 2020, I'm not yet sure if I should pick between Base or Advanced model.



What are the different hardware variants exactly?



About the Blade 15 Base with GTX 1660 with 120 Hz display: does it come with 2 slots? Is that SSD running on SATA port or M.2/PCIe port? Do the other Blade 15 Base models not have 2 slots?



About the Blade 15 Base with GTX 1660 with 144 Hz display: it says in the detailed description that the RGB is single-zoned, aka all keys have the same color, but then in the photo I can clearly see keys light up differently. If that's the case, what exactly do those "Single-zone RGB keys powered by Razer Chroma" mean?



All Blade Advanced models have "per-key RGB" but then the Blade 15 Base with 120 Hz screen has different photos... Which is which?



What's the fastest frequency the motherboard can handle in terms of RAM speeds?



Can you charge your laptop with Type-C? Is that Type-C DisplayPort compatible?
