MediaTek MT6575 vs Intel Atom Z2520

Comparisons   11-03-2021
   So, which chip or processor is better? Detailed compare data of benchmarks MediaTek MT6575 vs Intel Atom Z2520, speed examination of GPUs PowerVR SGX531 and PowerVR SGX544.
   This performance comparison involves two processors: MT6575 is single-core (ARM Cortex-A9) and Atom Z2520 is dual-core (Cloverview). Both processors went throughpower consumption test and battery life test. A step-by-step analysis of all the specifications of the SoCs, to make it easier to understand, is summarized in the table.
   From the video comparison, you can get the results of joint benchmarking in synthetic type tests such as PassMark, GFXBench, Geekbench, WebXPRT 3, PCMark, Quadrant, Octane V2, Vellamo, 3DMark, Neocore, Mozilla Kraken, AnTuTu, even the gaming performance of SoCs in Garena Free Fire - The Cobra, Mortal Kombat, Minecraft Bedrock, Fortnite, Sniper 3D, PUBG, Real Racing 3, Call of Duty: Mobile etc.
   After reading the results of joint benchmarks and videos, you can already make an briefed decision about which chipset is better to buy MT6575 or Atom Z2520 and which chip is better for gaming: Need for Speed No Limits, Madout2, CSR Racing 2, Asphalt 9.
