I can't say if more CPU or more memory required at the Host level or not. You need to check resource utilization at the Host level means at the time of login to remote desktop of any VM you need to monitor how much CPU and memory getting used. That may give you some idea. Then login to second VM through remote desktop and again monitor the resource utilization at the Host level.
You need to keep in mind that login to VM through RDP is happening at the Host filesystem level but Storage works in block level.
Hope this helps!
