Unisoc T9100 (T820) vs Apple A10 Fusion
Unisoc T9100 (T820)
► remove from comparison
The Unisoc T9100 (formely Unisoc T820) is a mid range SoC for Android based smartphones and tablets. It integrates an octa-core CPU with three clusters. One fast ARM Cortex-A76 clocked at up to 2.7 GHz, three more A76 performance cores clocked at up to 2.3 GHz and a power efficiency cluster of four ARM-Cortex-A55 cores with up to 2.1 GHz. The integrated memory controller supports LPDDR4/4X with up to 2133 MHz (2x 16 Bit). The integrated ISP supports two main cameras and two subsidiary cameras (up to 108 MPix). The integrated graphics card is an ARM Mali-G57 MC4 (4 cores) at up to 850 MHz. Unisoc also specifies that the T9100 offers hardware AI acceleration with up to 8.0 TOPS peak performance of the NPU.
The chip is manufactured on the modern 6nm EUV process.
Apple A10 Fusion
► remove from comparison
The Apple A10 Fusion is a system on a chip (SoC) from Apple that is built into the iPhone 7 and iPhone 7 Plus. It integrates four 64 Bit cores that are divided in two clusters. Two high performance cores are clocked at up to 2.34 GHz and should be around 40% faster than the Apple A9 (according to Apple) and two low power cores (up to 1.1 GHz?). Up to now its unclear if all four cores can be used at once (that need only 1/5 th of the energy in some use cases). At the release of the iPhone 7 it looks like that IOS is only using two cores at a time and automatically switches between the two clusters. Therefore, apps are seeing only a dual core. The principle is similar to the first generation of ARMs big.LITTLE concept.
The integrated graphics card of the SoC will most likely stem from PowerVR (again) and perform 50% faster at 2/3 of the power consumption (according to Apple).
All in all the chip includes 3.3 billion transistors, which is more than a current AMD Bristol Ridge (3.1) and Skylake Quad-Core (1.75) X86 SoCs.
