When you send a rendering job to Cloud Services, a dedicated machine is spun up with the following specifications:
CPU (Directly related to Renderworks rendering speed):
Intel Xeon E5-2670 - 8 cores 16 threads - running at 2.6Ghz to 3.0 Ghz
GPU (Related only to OpenGL rendering speed):
GeForce GTX 770 - 4GB VRAM - 1,536 CUDA cores
If your machine suprasses these specifications significantly, cloud processing may take longer than a local rendering. However if your machine is below these specifications, cloud processing can be expected to take less time than a local render.
