Qualcomm Snapdragon 805 vs HiSilicon Kirin 655

Comparisons   11-03-2021
   Well, which processor or chip is better? Detailed data of speed tests and benchmarks Qualcomm Snapdragon 805 vs HiSilicon Kirin 655, comparison of GPUs Adreno 420 and Mali-T830 MP2.
   This performance comparison involves two processors: Snapdragon 805 is gexa-core (Krait 450) and Kirin 655 is octa-core (ARM Cortex-A53). Both processors went through battery life test and power consumption test. A thorough analysis of all the technical characteristics of the chips, to make it easier to understand, is summarized in the table.
   From the video comparison, you can get the results of parallel benchmarking in software tests such as Octane V2, 3DMark, WebXPRT 3, PCMark, Mozilla Kraken, PassMark, Geekbench, GFXBench, Neocore, AnTuTu, Vellamo, Quadrant, even the gaming performance of CPUs in PUBG, Call of Duty: Mobile, Real Racing 3, Sniper 3D, Garena Free Fire - The Cobra, Minecraft Bedrock, Mortal Kombat, Fortnite etc.
   After looking at the data these benchmarks and videos, you can already make an briefed decision about which SoCs is better to buy Snapdragon 805 or Kirin 655 and which chip is better for gaming: Need for Speed No Limits, Madout2, Asphalt 9, CSR Racing 2.
