Comparisons   11-03-2021
   So, which processor or chip is better? Detailed comparison data of benchmarks Unisoc SC9850K vs MediaTek Helio A20, speed examination of GPUs PowerVR GE8300 and Mali-T820.
   This performance comparison includes two processors: SC9850K is quad-core (ARM Cortex-A7) and Helio A20 is quad-core (Cortex-A53). Both processors went throughpower consumption test and battery life test. A careful analysis of all the technical characteristics, to make it easier to understand, is presented in the form of the table.
   From the video comparison, you can get the results of joint benchmarking in synthetic type tests like Neocore, AnTuTu 8, WebXPRT 3, Quadrant, PassMark, 3DMark, Vellamo, Octane V2, GFXBench, Mozilla Kraken, PCMark, GeekBench 6, 5, and how good the processors are in games Fortnite, Mortal Kombat, Call of Duty: Mobile, Sniper 3D, Minecraft Bedrock, Garena Free Fire - The Cobra, Real Racing 3, PUBG etc.
   After reading the results these benchmarks and videos, you already be able to figure out which CPU is better to buy SC9850K or Helio A20 and which chip is better for gaming: Need for Speed No Limits, CSR Racing 2, Madout2, Asphalt 9.
