[Nexus 6 Q&A, Help & Troubleshooting] doitright:
I wouldn't say that the 808 is a better processor than the 805. The 64bit aspect is more marketing than practical, since you don't actually use a phone for tasks that benefit from 64bit. Those tasks are handled by dedicated hardware blocks. So what the 808 has, are 4 *weak* A53's, and 2 *power hungry* A57's. The 805 has 4 *strong/fast and power efficient* Krait 450's.

In fact, the 805 has been put against the 810 and actually came out VERY strong. In many cases, exceeding the 810.

*** note that in that article, it is important for you to recognize TWO very important facts about the tests;

1) They are comparing an MDP810/t (development tablet with massive internal heat dispersion plates) to a Nexus 6,

2) The Nexus 6 is running factory on-CPU full disk encryption, whereas the 810 is using special crypto instructions.

Both of those facts are to the benefit of the SD810, yet the only conclusion possible given the outcome, is that even WITH those points hurting the 805, it is still holding up against the 810.

And the 808? Basically just cut off two cores from the 810 and call it an 808.

As far as the rest of your points comparing the two phones...

1) The 5x has a MUCH better screen. While it is true that the claimed resolution is lower, the Nexus 6 has an RGBG AMOLED, which cheats on the resolution (it is only full resolution in GREEN, red and blue are only 2560x720). The differences are pretty obvious under a magnifying glass. The 5x, while only 1080x1920, is an HONEST 1080x1920. I would go so far as to say that I would choose a 6 inch 1080x1920 over this. And its not just about the visible artifacts, which yes, *are* hard to see.. but half the number of pixels to drive, the graphics *performance* will be a lot higher with the lower resolution screen.

2) Speakers... Nexus 6 speakers suck real bad as loudspeakers. As a headset, its fine (i.e., at lower volume pressed against your ear). The second speaker on the front is really quite pointless.

3) OIS? I can't tell the difference. It still blurs when you shake it during a picture.

4) More ram... yep, it does have a bit more ram, but, android knows how to manage ram very well, so you really shouldn't be able to tell a difference in device performance. Realistically, anything over 1 GB is adequate. Anything over 2 is just marketing fluff. At least for now.

5) 5x better form factor.... its the same form factor, rectangle. Maybe you are referring to the size?

6) 5x better proc... nope, as already discussed.

7) fingerprint scanner? Well, that may be useful for people with clean smooth soft fingers, but for the rest of us, fingerprint scanning is more trouble than its worth.

8) I don't get it with phone cameras. This race to super megapixels is idiotic when the two adjacent pixels bleed into each other. Phone cameras suck. All of them. We have a fairly cheap point and shoot digital camera, but through sheer lazyness, my wife got into the habit of using the phone. Couple of weeks ago she picked up the cheap point and shoot, and was blown away by how good the pictures were that came from it. Seriously... phone cameras ALL SUCK. There is nothing you can do to overcome the physical limitations when dealing with having to maintain a THIN phone. You just don't have the space to put in a decent lens. Every new phone that you get has claims of having a better camera than the last phone, yet phone after phone, I still can't tell the difference, they still suck.

9) USB type C. Yeah, it is kind of expected that during this period of transition, you will end up needing to get the cables that connect from the old to the new. The good news though, is that you don't need expensive powered converter boxes, its just a matter of the plug itself. Eventually, you are going to have to pick the first device to upgrade to the new plugs.

Here is my take on this;

I own a Nexus 6, and while it is a bit bigger than I like, I would NOT buy a 5x or a 6p. Neither offers a substantial benefit over what I already have. If they were a little bit more substantial, like having the snapdragon 620 and 820 like rumors and logic suggested, then they would be very tempting, but even then, its hard to say. I'm kind of glad that they didn't make them with the new chips though, since that temptation to upgrade now doesn't exist, so I can happily wait until next year and get something that is *actually* better than what I have now.

And I tell you, snapdragon 820 is really going to be something.
