There was a certain disappointment on the launch of the Radeon RX 500 series, because they use the same architecture of the RX 400, only with slightly higher clocks, while the enthusiasts were expecting for AMD’s new architecture, Vega.
This new series is a minor evolution on its predecessor, which is very common in the semicondutor industry, when a technology gets more mature and the chips become more efficient.
That’s why there was no surprise on our tests: the Radeon RX 580 was a little faster than the Radeon RX 480 on most benchmarks. Compared to its direct competitor, the GeForce GTX 1060 6 GiB, the Radeon RX 580 was, on average, similar, being a little faster on some games and a little slower in other ones.
So, we can say the Radeon RX 580 came to replace the RX 480 and fight the GeForce GTX 1060 6 GiB, being a video card with excellent cost/benefit ratio.
