With every new shiny tech there are people who buy it and claim it's a bigger deal than it is, and there are people who'd like to have it but don't, who claim it's not a big deal at all (mostly referring to that silly Verge article here, but also to a few comments on these forums)
The truth is - there is no way that the iPad Pro is faster in raw terms than a quad-core i7, but the fact they can even compare and we're talking about it, and the iPad's CPU is passively cooled, small and barely even warm during intense tasks - is amazing. And it feels fast. I have that MacBook Pro and an iMac 5K and a lot of things (due to software, not hardware) work slower on my Macs than on my iPad Pro: reading PDFs is noticeably slower, certain apps like Evernote or OneNote are much more choppy, even scrolling a page in Safari feels more zippy on an iPad. And compare smudging an image with a large smudge brush in Photoshop on a Mac and in Procreate on an iPad - iPad and Procreate win so much, it's not even funny.
Is the hardware faster? No. But it feels faster, and that's what matters most. Of course, it is also very limited compared to a Mac. I love Macs, I plan on using them for a long time and can't imagine pro work without them. But the iPad Pro is incredible and for a lot of tasks - it's just better. So, it is something to get excited over, even if we go over the edge a bit.
