Maybe I am being pessimistic.
The concept of the Switch being at home or on the go is going to be the limiting factor on the performance of the system. With its form factor I dont see how it is going to achieve x1 + levels of performance? The real question becomes what will the disparity be between docked vs non docked mode in regards to performance?
Okay let me try to break it down here-
The main components which determine the performance of a system are the CPU, GPU and RAM. The Xbox One and Playstation 4 use very high powered GPUs which render the images of a game. They have relatively weak CPUs, where the CPU performs mostly background calculations that are used in physics, collision, AI, and weather functions, among other things.
The Switch is rumored to have a CPU which is more powerful than those in the XB1/PS4, regardless of the architecture of that CPU being ARM (vs the x86 in the XB1/PS4). The Switch is also rumored to have a GPU which is much more powerful than the Wii U, but is unable to reach XB1/PS4 power due to the constraints of being a handheld device powered by a battery.
The CPU they are using on the other hand is made for these types of battery powered devices, so it is able to run very quickly on a very low amount of power. Therefore, regardless of its form factor or whether it's docked or not, the CPU will be very strong compared to the competition. The GPU will be where this falls short of the competition.
Your past few posts have argued that the CPU will be a limiting factor, and that their choice to use ARM will once again handicap them. Everything we know indicates that this, specifically, is not true at all.
**I am not an expert, please correct me if any of this is wrong.**
