MediaTek Helio A20 vs Unisoc SC9853I

Comparisons   11-03-2021
   Well, which chip or processor is better? Detailed comparison data of benchmarks MediaTek Helio A20 vs Unisoc SC9853I, speed testing of GPUs Mali-T820 MP2 and PowerVR GE8300.
   This performance comparison involves two processors: Helio A20 is quad-core (Cortex-A53) and SC9853I is octa-core (ARM Cortex-A55). Both processors went through battery life test and power consumption test. A thorough analysis of all the specifications, to make it easier to understand, is made by the table.
   From the video comparison, you can get the results of joint benchmarking in special testing software like PCMark, Mozilla Kraken, Octane V2, Vellamo, GFXBench, Geekbench, WebXPRT 3, PassMark, Neocore, Quadrant, AnTuTu 8, 3DMark, even the gaming performance of SoCs in Fortnite, Mortal Kombat, Call of Duty: Mobile, Garena Free Fire - The Cobra, Sniper 3D, Real Racing 3, PUBG, Minecraft Bedrock etc.
   After reading the results of all benchmarks and videos, you can already make an informed decision about which chipset is better to buy Helio A20 or SC9853I and which chip is better for gaming: Madout2, CSR Racing 2, Need for Speed No Limits, Asphalt 9.
