Cloud Computer is a technology that serves you as a standard computer like a laptop, PC, or Mac, but all the processes are taking place in the cloud. The key difference is in the resources you are getting access to.
A standard PC would provide you with a single processor, while Renderro Cloud Computer supports up to 64 processors.
Accordingly, while your 2 years old Mac has a single integrated graphic card, Renderro Cloud Computers offer a NVIDIA A10G, giving you pure power for all your production needs.
