See, the thing is that OpenGL was designed in the era when computers had one processor with one "core" (back then we didn't even talk about cores). These days, mobile chipsets have anything between 4 and 10 CPU cores and OpenGL just doesn't make efficient use of them. Here lies Vulkan's strength - it can spread the workload between all available cores. This gives it a two-fold advantage. First, many entry-level and mid-range chipsets have only power-efficient...
