HiSilicon Kirin 620 vs Intel Atom Z3580

Comparisons   11-03-2021
   So, which processor or chip is better? Detailed data of speed tests and benchmarks HiSilicon Kirin 620 vs Intel Atom Z3580, comparison of GPUs Mali-450 MP4 and PowerVR G6430.
   This performance comparison involves two processors: Kirin 620 is octa-core (ARM Cortex-A53) and Atom Z3580 is quad-core (Moorefield). Both processors went throughpower consumption test and battery life test. A thorough review of all the technical characteristics of the SoCs, so that it can be easier to understand, is summarized in the table.
   From the comparison video, you can get the results of parallel benchmarking in special test applications like Neocore, Octane V2, Geekbench, AnTuTu 8, PassMark, WebXPRT 3, 3DMark, GFXBench, Quadrant, Mozilla Kraken, PCMark, Vellamo, even the gaming performance of processors in Fortnite, Minecraft Bedrock, Call of Duty: Mobile, Real Racing 3, Mortal Kombat, Sniper 3D, PUBG, Garena Free Fire - The Cobra etc.
   After looking at the data of parallel benchmarks and videos, you already be able to figure out which chipset is better to buy Kirin 620 or Atom Z3580 and which chip is better for gaming: Need for Speed No Limits, Madout2, Asphalt 9, CSR Racing 2.
