A:Answer Exact same laptop aside from CPU / GPU
15-BL012DX - 7th Gen Intel CPU, Nvidia 940 MX GPU
15-BL112DX - 8th Gen Intel CPU, Nvidia MX150 GPU
The 8th gen CPU bumps the core count from 2x to 4x. Nvidia MX150 will also offer better performance for gaming, Photoshop, Video Editing, CAD, ect.
Both will work fine, but the BL112DX is a nice performance bump from the previous version.
