What's the significant differences between devices running the two?

Do cores even matter on phones?

yes, say something with 4 A53s is much worse than the 8 A53s used in many low or midrange phone CPUs.

yeah the 435 is way better. IMO for lower end mobile CPUs, Kirin and Exynos are better.

So essentially the devices load is spread around more resulting in better performance when doing something like uh 5 chrome tabs open and listening to something on YouTube?

yeah and most phone stuff is pretty optimized to multiple cores because the flagship 835 and 8895 are both 8 core big.LITTLE. Difference is that 835 has Kryo for big and little while 8895 uses their own M2 for big and the industry standard A53 for little.

Okay thanks for helping me get a better understanding of mobile hardware

While a good chunk of individual app performance is dependent on single-threaded performance, many background tasks can be farmed to many smaller cores quite efficiently. Android itself seems to be particularly optimized for this, enough so that I think it might actually perform worse if it were somehow ported over to iPhone hardware.

Snapdragon SoCs? LOL!

They're pretty much everywhere (in the US) from the low end to the flagships. Many of their low to mid end designs tend to be fairly boring nowadays (some generic A53 or A7 setup), though the 650 and 660 are quite decent (that Cortex A72 gets so little love), as are the 820 and successors.

 

Beating a dead horse (very repeatedly, I might add), though no one on the Android side is coming close to matching Apple's per-GHz/Core performance, though I have a feeling that even if Android were ported over, it probably wouldn't be any faster than on flagship Android devices. As many core devices are common on the Android side, Android was probably developed to spread around it's background tasks.

Yep it was. Even right now Apple is still only really using 2 of its cores at a time and hands the tasks off to either batch of cores as the performance is needed. 2Big cores and 1 Little cores. I cannot wait to see the A11 chip in action. I cannot imagine the graphics that Apple is going to get out of the next iPhone. 

 

This is why in some speed tests the iPhone can fall behind a little in app opening contests (also the pretty animations take up time).

While the CPU designs tend to take different approaches between iOS and Android, the GPU performance tends to be remarkably competitive, definitely a long cry from the days of the iPhone 4S where the A5 chip just facerolled everything. Iphone 6S beat everything but Tegra X1. Snapdragon 820 comes and stomps that. Then iPhone 7 leapfrogs that. And so on and so forth. With Vulkan available, not even the Metal api can claim a definite advantage anymore, with the saving grace for Apple being the games themselves.

my S7 has a monster CPU, the 8890 on mine scores almost as high as the 835 in Geekbench

The Apple A11 will be announced extremely soon. Leaks suggest its at least 3 years ahead of anything Qualcomm has right now.

qualcomms are pretty bad. They get rekt in everything except GPU

Unfortunately, there really isn't anyone in the Android space that is appreciably better than Qualcomm. Even the Exynos is only marginally better. Though we're derailing the train at this point.

nah, exynos is plenty better, maybe around 0.5 to 1 years ahead. Mediatek gives better raw power at the same cost but they are unstable and use a lot of power. Low end Exynos IMO is the best for midrange. The CPU in the 2017 A5 has 8 A53 cores on 14nm finfet and a 3000mah battery which results in a crazy long lasting phone. on the same test the S7 got 70h when the A5 got 100h

I do have a need to access company websites that are, to put it gently, very lightly optimized, so having some brute on tap is a big help. Cortex A53 does not provide that for me.

 

The gap is quite narrow at the top end.

true. My S7 is not laggy in anything I do. i definately prefer it over the LG G6

I'm assuming that's why most Chinese brand phones use mediatek but you never see them promoting battery life
