Something About the Samsung Exynos 7872

Yesterday we’ve talked about the Samsung Exynos 7270 that used on the M6/M7/M9, today let’s say something about the Exynos 7872 SoC that used on the FiiO Android-based smart HiFi music player M11. The Exynos 7872 is a middle SoC that Samsung made for smartphones, which is made on the 14nm FinFET process, and integrated two 2.0GhZ ARM Cortex A73 cores and four A53 cores.

The overall performance of Exynos is comparable to Qualcomm Snapdragon 625, and MTKP25. It’s been widely used on Samsung’s smartphones, but this is the first time used on music player.

The Exynos 7872 is more than enough for a music player, with the 3G DDR, it’s able to support well for streaming apps. So we no need to make a white-listed third-party music streaming apps due to the performance limitation. And because of the 14nm FinFET process and relatively new cores, the standby current can be made to a very low level. The deep sleep time can last for 50 days when WiFi/Bluetooth is turned off per one full charge. So it’s very convenient to plug and play.

The performance of Exynos 7872 is on the top list of music player’s SoC, and we also took full advantage of it and developed some new features such as ALL TO DSD (can transfer the PCM formats files to DSD), better dynamic EQ and decoding iSO tracks in DST codec, etc. All of these better experience and sound quality are brought by the high performance SoC.
