One of the things Nvidia excels at, and has done very well in is supplying the right ecosystem for writing performant GPU code. This really pushed the adoption of GPUs forward. Writing good, fast, high performance code for many x86 nodes is still quite difficult. Nvidia's CUDA stack including Thrust, CUB, cuBLAS and other libraries really made it easy to write parallel code, without thinking too much about the lower level operations.
