Cost-Effectiveness Evaluation

Performance to price ratio. The higher, the better.

RX 550 and ATI HD 4550 have a nearly equal value for money.

Detailed Specifications

General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked.
