Building a capable gaming PC is relatively simple: you start with the best graphics card you can afford, and combine it with an appropriate CPU, motherboard, and other components. With every generation of GPU normally improving in features, performance, and pricing relative to its predecessor, the launch of any new GPU is cause for celebration. But AMD's Radeon VII is both more and less than other GPU launches.

Radeon VII is the first GPU to be manufactured using 7nm lithography, a bold statement from AMD. On the face of things that's a big jump from the previous 14nm technology (and 12nm/16nm as well). However, the numbers used for a manufacturing process often contain a fair amount of marketing. In the Radeon VII's case, it's good progress, but it's not a revolution. And it's not enough to push the Radeon VII ahead of the competition, especially at a steep $700.
