[Update: While Xiaomi is a minority investor of YI in China, and YI products are sold in Xiaomi stores, Xiaomi does not own YI Technology nor does it own, produce or design any of its products. Therefore any mentions of Xiaomi in the article should be read instead as “YI Technology.”]
Xiaomi is about to launch a new 4K sports camera with Xiaomi Yi 4K powered by Ambarella A9SE dual core Cortex A9 processor and supporting video recording up to 4K @ 30 fps.
The specs of the new camera is actually pretty similar to what you’ve got on GoPro HERO4 Black camera, plus some improvements as the comparison table below shows. I found the data on GeekBuying blog, so it could not be entirely unbiased, but it still gives an idea.
