GPUs are used in [https://en.wikipedia.org/wiki/High-performance_computing HPC] environments because of their good [https://en.wikipedia.org/wiki/FLOP FLOP]/Watt ratio. The instruction throughput in general depends on the architecture (like Nvidia's [https://en.wikipedia.org/wiki/Tesla_%28microarchitecture%29 Tesla], [https://en.wikipedia.org/wiki/Fermi_%28microarchitecture%29 Fermi], [https://en.wikipedia.org/wiki/Kepler_%28microarchitecture%29 Kepler], [https://en.wikipedia.org/wiki/Maxwell_%28microarchitecture%29 Maxwell] or AMD's [https://en.wikipedia.org/wiki/TeraScale_%28microarchitecture%29 Terascale], [https://en.wikipedia.org/wiki/Graphics_Core_Next GCN]), the brand (like Nvidia [https://en.wikipedia.org/wiki/GeForce GeForce], [https://en.wikipedia.org/wiki/Nvidia_Quadro Quadro], [https://en.wikipedia.org/wiki/Nvidia_Tesla Tesla] or AMD [https://en.wikipedia.org/wiki/Radeon Radeon], [https://en.wikipedia.org/wiki/AMD_FirePro FireProRadeon_Pro Radeon Pro], [https://en.wikipedia.org/wiki/AMD_FireStream FireStreamRadeon_Instinct Radeon Instinct]) and the specific model.
