Quality difference MediaTek MT5596A vs S912

I’ve just bought a H96 Pro+ S912 with 3GB and currently running MRMC directly on my
Philips tv with the following specs
SOC: MediaTek MT5596A
CPU: ARM Cortex-A53

Will there be huge differences? Why I bought the H96 is when some files are larger than 25GB it will suffer from stuttering, As you might see I’m pretty novice at this, any help would be appreciated.

I MediaTek MT5596A even supported by CE? If so, what about MT6582 (quad-core) and/or MT6592 (octa-core)?

I don’t think so no… I’m running mrmc android tv app now. Just want to know if the quality of 4k will be superior with amlogic s912 and CE.
