GigaPixels - higher is better
GigaTexels - higher is better
GB/s - higher is better
GFLOPs - higher is better 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.

The combined score is measured on a 0-100 point scale. Combined synthetic benchmark scoreThis is our combined benchmark performance score. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly. GeForce 940MX outperforms Radeon R5 M420 by 208% in our combined benchmark results. PassmarkThis is the most ubiquitous GPU benchmark, part of Passmark PerformanceTest suite. It gives the graphics card a thorough evaluation under various types of load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities. Benchmark coverage: 25% GeForce 940MX outperforms Radeon R5 M420 by 208% in Passmark. Gaming performanceLet's see how good the compared graphics cards are for gaming.
