To be honest, I was quite disappointed to see the Nokia 6 coming with a low mid-range SoC, the 64-bit Snapdragon 430 processor and not the newer Snapdragon 652 or the 653 ones. It's 2017, so why use a 2015 Soc in 2017. I probably can just wish that if Nokia brings this phone to a global market it will come with the SD625 and not the SD430 which in my opinion doesn't suit a mid-range device like the Nokia 6. I think that many people will be disappointed with that decision. It might sell well in China, but if you bring it to the west, I doubt that many people will prefer buying it over other better mid-range phones with more up-to-date Soc.
Don't get me wrong, an 1.4 GHz Octa-core processor with Adreno 505 can run any game with not problem, but this phone will definitely be compared with other mid-range devices that might be more compelling. Of course the processor isn't everything, and you need to do your own math and looks at the other features as well. I negatively criticize Nokia for this decision because I think it should have used at least the SD 650 on this phone. I hope that its future phones will be more compeling.
