Intel Atom x5-Z8550 vs Unisoc SC9863A

Comparisons 11-03-2021

Well, which chip or processor is better? Full data of benchmarks and speed tests Intel Atom x5-Z8550 vs Unisoc SC9863A, comparison of GPUs IMG8322 and Intel HD Graphics 400 (Braswell).

This performance comparison involves two processors: Atom x5-Z8550 is quad-core (SoFIA) and SC9863A is octa-core (ARM Cortex-A55). Both processors went throughpower consumption test and battery life test. A thorough analysis of all the specifications, so that it can be easier to understand, is presented in the form of the table.

From the comparison video, you can get the results of parallel benchmarking in special test applications like Neocore, Vellamo, PCMark, WebXPRT 3, GFXBench, GeekBench 6, 5, AnTuTu, Octane V2, Quadrant, PassMark, Mozilla Kraken, 3DMark, even the gaming performance of SoCs in Call of Duty: Mobile, Garena Free Fire - The Cobra, Mortal Kombat, Real Racing 3, Sniper 3D, Minecraft Bedrock, PUBG, Fortnite etc.

After looking at the data these benchmarks and videos, you already be able to understand which SoCs is better to buy Atom x5-Z8550 or SC9863A and which chip is better for gaming: Madout2, Need for Speed No Limits, CSR Racing 2, Asphalt 9.
