Qualcomm Snapdragon 678 vs MediaTek Dimensity 800U

Comparisons   11-03-2021
   So, which chip or processor is better? Detailed compare data of benchmarks Qualcomm Snapdragon 678 vs MediaTek Dimensity 800U, speed examination of GPUs Adreno 612 and Mali-G57 MC3.
   This performance comparison involves two processors: Snapdragon 678 is octa-core (Kryo 460) and Dimensity 800U is octa-core (ARM Cortex-A76). Both processors went through battery life test and power consumption test. A thorough review of all the specifications of the CPUs, so that it can be easier to read, is presented in the form of the table.
   From the comparison video, you can get the results of parallel benchmarking in software tests such as GeekBench 6, 5, PassMark, Neocore, WebXPRT 3, AnTuTu 8, Quadrant, GFXBench, PCMark, Mozilla Kraken, Vellamo, Octane V2, 3DMark, even the gaming performance of CPUs in Garena Free Fire - The Cobra, Minecraft Bedrock, Call of Duty: Mobile, Fortnite, Sniper 3D, Real Racing 3, Mortal Kombat, PUBG etc.
   After looking at the data of joint benchmarks and videos, you can already make an briefed decision about which chipset is better to buy Snapdragon 678 or Dimensity 800U and which chip is better for gaming: Madout2, CSR Racing 2, Need for Speed No Limits, Asphalt 9.
