Are you saying once 5.0 comes out for the note it will run slowly? If so wouldn't the Nexus 6, which has the same chipset as the Note 4 and running 5.0, run slowly?
Good question.
Note 4 and N6 have same S805 chip. But, N6 runs pure Android which is lightweight and more fluid. Note 4 runs Touchwiz which is heavy handed, bloated, and sluggish, esp for the Note series. This is why even with S801 chip, Galaxy S5 stuttered with the regular Touchwiz version.
S805 chip is only a MILD ramping up from S801 in terms of computational power. S805 is more about GPU improvements. I am sure that Note 4 will do good with the current Kitkat-based Touchwiz for Note series.
Except for a the few low-end ARMv8 chips coming out from Qualcomm (S610 for example) and Exynos 7 (Samsung Note 4 international version), ALL Android flagships have a chip that is based on ARMv7 architecture, which came out over 25 years ago! (ARMv8 came out at end of 2012.)
Lollipop (5.0) is optimized for ARMv8 chip architecture. It is for the next gen of chips coming out next month or so...but more importantly, it is to support the high end ARMv8 chips coming out next year (S810 for example). Why does this matter?
Remember, iPhone 5s could do things that iPhone 5 could not...games ran better, graphics were better, and some apps just no good on iPhone 5. (This was before Apple introduced METAL, which made the difference even more startling in graphics.) This was because ARMv8 architecture is FAR SUPERIOR to ARMv7 (which is what Snapdragon 800/801/805 etc are based on). ARMv8 is not just for 64-bit apps, but it also runs 32-bit apps better than ARMv7.
By next year, all the big names developer will optimized their apps AND make apps that are for the latest chips...and those chips are: S610, S810, and Exynos 7. All are ARMv8 chips. All are on Lollipop.
Do you remember Gameloft Asphalt 8? What did they do at the end of 2013? They optimized the game for S800 chips bc that was what most flagships had at the time. (Flagships buyers tend to be the folks who spend the most money on in-app purchases.)
What do you think the developers will do when S810 and Exynos 7 become mainstream in early 2015? Money drives optimizations.
Now, Nexus 6...you're correct. I think that anyone buying N6 is making a huge mistake. People who buy flagships NOW, including Note 4 and N6, are just shooting themselves financially because by next year, they will be FORCED to buy another phone! Nexus comes out every year. Google knows that. But people tend to buy tablets less often...and thus, Nexus 9 has Nvidia K1 Denver chip (ARMv8 64-bit chip). In addition, up to now, there has not been an ARMv8 chip that is available in a phone on Android. Qualcomm S610 is now only appearing in mid-level HTC phones. Exynos 7 just came out with Note 4 (international)...and unlikely anyone besides Samsung will use Exynos chips.
And these 1st gen ARMv8 chips from Qualcomm (s610, S810) and Exynos 7 are based on GENERIC cores from ARM, which are basically very primitive cores based on ARMv7 cores. It won't be till another year (late 2015) will we see CUSTOM designed ARMv8 cores from Qualcomm and Samsung.
Apple iPhone 5s (introduced in 2013) has Apple A7 chip, which is a fully CUSTOM-designed ARMv8 chip, capable of decoding, issuing, executing and retiring up to 6 instructions/micro-ops per clock! (Yes, that is MORE advance than upcoming flagship Qualcomm S810 and Exynos 7 chips which can only do 3 instructions at a time because they are based on GENERIC ARM cores.)
Hope this helps.
