REALITY: The PCoIP protocol is a comprehensive solution with options for stateless hardware zero clients
While some workload may result in the PCoIP protocol using more CPU than other protocols, the VMware office productivity interactive workload benchmark shows that the PCoIP protocol uses less CPU resources than XenDesktop 4 or RDP7. Thus, the scalability of a VDI deployment using the PCoIP protocol should be equal to or higher than XenDesktop 4 or RDP7 (however, the PCoIP user experience will be better). Furthermore the PCoIP software encoder requires less memory on the server than XenDesktop 4 or RDP7, which further helps scalability,
One very important advantage of host-rendering or server-side processing is the enablement of highly capable, zero-clients on the receiving end. A completely stateless, hardware zero-client requires no operating system patches or anti-virus software. They can be very low-power devices while still delivering the highest possible user experience. This is just not possible with a client-rendered device. A PCoIP zero-client can further improve the opex savings associated with moving to a VDI deployment by reducing power consumption, eliminating management overhead, and providing a longer product life cycle.
In many ways, PCoIP technology is the only complete protocol. The graphics independence of the protocol means that all applications today and tomorrow will “just work” and not have to wait for an update to the protocol. Furthermore, no other protocol provides a true, zero-client to compete with the PCoIP Portals and integrated monitors from a wide variety of leading OEMs.
