Test System & Methodology
We introduced our new test system and methodology in How We Test Graphics Cards. If you'd like more detail about our general approach, check that piece out. Specifically, for this review, we split testing between our U.S. (performance) and German (power, acoustics, thermal) labs.
Because the Radeon RX 550 is distinctly entry-level, we had to re-think our approach to measuring its performance. Instead of using a high-end platform to alleviate platform-imposed bottlenecks, we pulled Core i3-6320s from our library of processors and yanked half of the DDR4 memory out of our MSI motherboard.
We also wanted to use the Core i3's HD Graphics 530 engine (driver version 22.214.171.12427) as our performance baseline. After all, the folks shopping for $80 graphics cards are typically suffering with integrated solutions. AMD's modern Radeon RX 460 and older Radeon R7 260X (driver version 17.4.3) join the comparison for a bit of context, showing what you can expect after adding a discrete GPU.
The hardware used between our two labs includes:
