Depends on the tablet, Microsoft have been sticking dual core i7's in the Surface Pro 4 and Surface Book devices with up to a terabyte of storage and RAM options up to 16GB. The sticking point is heat being generated and disposed of.Karadalis said:To me it seems that their hardware specs are rather weak (what can you expect from a tablet?)
In fact it's a little difficult tracking down exactly what CPU is in the WiiU; according to Wikipedia it's called an Espresso, was developed by IBM and the PCB itself contains both CPU and an AMD GPU. So yeah, depending on how big the make the tablet portion of the Switch, lets charitably say the size of a 1st Gen iPad or something, then I suspect you can get some respectable hardware in there that will be capable of playing the games Nintendo intend to make. How this measures up for 3rd parties is another story.
