Are we talking about early 2010 or what? xD. Because back then MTK wasn't as matured as it is today. MTK6752 doesn't heat up at all. In fact
it even runs cooler than Snapdragon 800 Period.
And Honor 4C has a In-house packaging which can be Compared with snapdragon 400 or 410 but Bro you just cannot say that its Better than MT6752 which is even faster than snapdragon 800. maybe even 801.
About Camera quality. They are pretty much the same. Based on their reviews. IMO They both have generic cameras but that is to be expected of a mid-ranged phone.
One more thing. Huawei 4C Only supports
3G vs Lenovo P70 which is a
4G LTE supported phone.
Anyway i'm posting the benchies below. So you have a good idea of what these MTK chipset can do
Here you Go
Lenovo P70
