Intel Atom Z2520 vs Spreadtrum SC7731C

Comparisons   11-03-2021
   So, which chip or processor is better? Full comparison data of benchmarks Intel Atom Z2520 vs Spreadtrum SC7731C, speed examination of GPUs PowerVR SGX544 and Mali-400 MP2.
   This performance comparison includes two processors: Atom Z2520 is dual-core (Cloverview) and Spreadtrum SC7731C is quad-core (ARM Cortex-A7). Both processors went throughpower consumption test and battery life test. A careful analysis of all the technical characteristics of the processors, to make it easier to read, is made by the table.
   From the video comparison, you can get the results of parallel benchmarking in special test applications such as GeekBench 6, 5, Vellamo, GFXBench, Neocore, 3DMark, Mozilla Kraken, Quadrant, Octane V2, AnTuTu 8, PCMark, WebXPRT 3, PassMark, even the gaming performance of SoCs in Minecraft Bedrock, Real Racing 3, Call of Duty: Mobile, Sniper 3D, Mortal Kombat, PUBG, Garena Free Fire - The Cobra, Fortnite etc.
   After reading the results these benchmarks and videos, you already be able to figure out which chipset is better to buy Atom Z2520 or Spreadtrum SC7731C and which chip is better for gaming: Need for Speed No Limits, Madout2, Asphalt 9, CSR Racing 2.
