Cost-effectiveness evaluation

Performance to price ratio. The higher, the better.

RX Vega 56 has 3225% better value for money than Radeon 550X.

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.
