Qualcomm's Upcoming Mid-Range Snapdragon 620 Chip Outpaces Snapdragon 810 & Exynos 7420 in Leaked Geekbench Benchmark
SD 620 is benchmarking better than 810, and even holding its own against the Exynos 7420.
As for Kirin, Huawei's in house SOCs, they are total beasts.
Leaked Geekbench benchmarks of the 950 blew away the 7420 and can almost assuredly keep up with the 820.
BUT I'd personally prefer the SD820 for the Huawei Nexus 6 because of a few things.
1. Qualcomm makes a proprietary battery app called "battery guru" that spends 3 days studying how you use a phone and then automatically optimizes the settings across the phone to increase battery life 25%-50%. It's a crazy awesome app and any person with a phone with a Qualcomm chip that isn't using it is just wrong.
2. XDA support is much stronger for Qualcomm than for other chip sets. That means if you ever want to root and flash new roms (say once Google stops updating your Nexus) then it would be better to have a SD 820 than a Kirin 950.
Then again, given that the Nexus 4 got 3 years of upgrades I'm confident that any new premium Nexus flagship, especially a phablet, will get at least 3 maybe even 4 years of support which means you could own it 4 or even 5 years.
By then the battery will be shot to heck and useless and you'll definitely want to upgrade.
By the way, my philosophy for phone upgrades is like car upgrades. The anticipation is the best part and by waiting as long as possible to upgrade you really get a sense for the progress that phones have made.
For example, had I gotten a Nexus 4 I would still use it because its getting 5.1.1. That means I would now be finally looking to upgrade and have my choice of either a Nexus 6 for its bigger screen or the more advanced Nexus 6 by Huawei for its USB C, finger print scanner, and larger battery.
Upgrading from a Nexus 6 to a Nexus 6 (2015)? Other than a smaller screen and slightly bigger battery I won't really see a difference.
BUT 3 years from now? Oh yes, that will be something sweet.
It's even better with cars. My current car is a 2006 Volvo XC90 and within 6 months I'll be getting a 2016 Prius.
That upgrade will be like going from the 737 to the star ship enterprise!
Cars and phones are now both sufficiently advanced that you really can't tell the difference between annual or even bi-annual upgrades.
Wait 3, 4, or 5 years (assuming Google respects the premium Nexus phablet owners enough to go past its 2 year pledge) than you will still experience a child like thrill at a new phone.
Besides, I'm an investment writer for The Motley Fool and I can't get past the fact that $600 for a new phone that I don't need can be turned into $15,000 in the future, via deep value dividend investments.
Like Buffett, I'm cursed to never be able to buy cool toys, become I'm too darned practical
