Mediatek:
It is a Taiwanese company. It uses more cores in it's processors(like octa core,hexa core,deca core).
Battery Life:
The mediatek chipsets are known to be more power draining and results in less battery life.Now they are optimizing their processors to be more power efficient but still lags behind their competetion in terms of battery life.
Performance:
Performance wise their processors are very good.Due the availability of extra cores,mediatek processors can handle intensive and heavy tasks and they are very good at multi-tasking.But we can see all this practically if we have sufficient Ram.Yes more cores demand more Ram to give best performance.
Heating Problem
Now coming to the heating problem. All the processors deliver heat while performing tasks. Mediatek processors deliver more heat(more cores=more heat) than the others.
Graphics:
Coming to graphics,Mediatek employs Mali graphics which is a third party graphics vendor(So graphics architectue is different from cpu and its performance may not match with cpu). It is really important to match the performances of cpu and gpu(graphics) so that the whole chipset performs efficiently and effectively.
2.)Snapdragon:
Snapdragon chipsets are manufactured by Qualcomm (American) company.
Snapdragon chipsets are not only just CPU's they incorporate other many processors in their chipsets.This is the main difference between Snapdragon and other chipsets.
Snapdragon chipsets are named as SoC's(System on chip) which means their chipsets(SoC's) have a CPU,GPU(Adreno Graphics),Image processor,Media processor,DSP(Digital Signal Processor),Cellular Modem unit,Wifi Modue,Radio Module,GPS Module,...etc. All these modules and Processors are inside of a snapdragon chip.Yes they incorporated all these things inside their chips.Hence their chips are costly.
Battery Life:
Snapdragon chipsets are best in terms of power efficiency compared to all other chipsets.
Performance:
Performance wise they perform really well. In multi-tasking,gaming,handling heavy and intensive tasks they are very good.
Heating Problem:
Snapdragon Processors generally deliver less heat compared to Mediatek and Intel Atom(Except the Snapdragon 810 Chipset-that faced many heating issues.)
Graphics:
Coming to graphics, they manufacture their own graphics called Adreno Graphics and incorporate into their chips. So here the performance of cpu and gpu are matched.
