Razer Blade 15 Base Edition (2021)

2020 will go down as a horrible year for getting hold of new graphics card. I still know people who ordered the new Nvidia Series 30 graphics card at launch in September 2020 and still have not been able to receive it. One avenue to get a new Series 30-card might be to go the laptop route instead as it is much easier to get hold of those. Nvidia recently released their RTX 3060, RTX 3070 and RTX 3080-GPU’s for laptop and today I am testing the Razer Blade 15 Base Edition that comes with a Intel i7-10750H, a 15” 165 Hz QHD-screen and a RTX 3070.
