In most of the 3DMark tests, the RX 480 scored around half as well as the GTX 1080. That's actually quite impressive, considering that the 1080 costs upwards of $600. Notably, the RX 480 was also slightly faster than comparable benchmarks from NVIDIA's GTX 970, which still costs more than $300 today (and was previously the bare minimum you needed for VR).

I knew from the get-go that this card wouldn't be much of a 4K contender, and while the results I got weren't playable, I'm still surprised at how well it did compared to the GTX 1080 and the R9 Fury X. What really impressed me, though, was the RX 480's 1440p performance with maxed-out settings. It managed to reach nearly 60 frames per second in most titles, which has been my PC gaming goal for the past few years. What you lose out in resolution compared to 4K, you get back in overall smoother performance (and the ability to use more elaborate graphical settings).

When it comes to real-world performance, the RX480 felt just as fluid as the GTX 1080 when playing Overwatch in 1440p with all graphics settings at their maximum. It never dipped below 60 fps, even when things got incredibly hectic. These days, that's all I really ask for in a video card. With the new Doom, it hovered between 55 and 60 fps, which is still commendable given how demanding that game can be. It didn't fare as well with The Witcher 3, getting around 43 fps, but that's also a game that eats GPUs for breakfast.
