Which processor is best for android phone?

snapdragon if those are the two you are going to compare.....samsung has exynos as well. on sammy's exynos chips makes the phone rootable while snapdragons in general are harder to root...if at all.

 

To be cler, it's only Snapdragon Samsung's that are hard to root, and that's because of the way Samsung locks those down (largely at the request of North American carriers). Other phones based on Snapdragon platforms can be perfectly straightforward to root, and can be easier for some sorts of mods than Exynos devices because Qualcomm are more open with some technologies than Samsung are with their Exynos systems.

Other than rooting, it depends on what you want. But in general I tend to view MTK as lower-end devices. Certainly on graphics the Snapdragons have the MediaTek's beaten comfortably. But it also makes a big difference which SoC from each manufacturer, e.g. a Snapdragon 400-series is an low-end SoC, a 600 is low-middle, 700 series are upper-middle (and good enough for most purposes while using less power than the flagship chips) while the 800 series are the flagship SoCs. There is a huge difference between an 800 series and a 400 series Snapdragon, and there are similar differences between different MTKs. And of course newer chipsets tend to be better than older ones. So rather than a generic "snapdragon or mediatek" you really should be looking at what specific SoC the particular phone has.

 

It's not exactly true. If you are referring to Samsung only, then yes, most of their Snapdragon models are dedicated to the US, and in the US carriers are paying big money to make sure that their phones have a locked bootloader and cannot be rooted. Europe have no such problems since they don't have shady carriers like the US ones, so there is no reason to prevent a customer from unlocking the bootloader. As for the other brands, such as Motorola, they have an amazing bootloader unlocking policy which allows people even from the US to unlock the bootloader (Except for TracFone) for their Qualcomm or MTK CPUs. However, Qualcomm still has the win in Custom ROMs, because a lot of people are very familiar with the process of building device sources for Qualcomm devices. As for Mediatek, I have not seen as many ROMs as the older phones in the MTK6572 days. So for me Qualcomm wins here.

 

i was only referring to sammy's only, but thanks for clearing that up for others.....much appreciated.
