I understand that, what I meant was that if you need more processing power than the V can offer, you will also need something more powerful than the surface. The difference between the two is speed (not counting graphics, Surface has Iris which is better than HD, but Eve has Thunderbolt), not power.
For example, I have a rather powerful desktop I use for most of my work, because a lot of the stuff I do my surface simple cannot handle. And I regularly need to run code that my desktop cannot handle, so I send it off to a super computer and let that do the heavy lifting.
If somebody needs to do heavy photo/video editing, programming/compiling, or gaming that the V can’t handle, neither can a Surface, because in the grand scheme of things they aren’t that different. The better processor in the Surface makes it a bit faster, but the V can do everything the Surface can do (just a tad slower).
Also, keep in mind, the V was supposed to be delivered by the time the 2017 Surface was announced, it was designed to compete with the SP4 (which had considerable worse battery life than the new Surface).
