Apple A9 vs Samsung Exynos 9611 vs Apple A9X

Apple A9

The Apple A9 is a high-end dual-core ARM SoC for smartphones. It was announced in Sept. 2015 in the new iPhone 6s and 6s Plus. Technical details were not published, but the CPU part should be about 70% and the GPU 90% faster than the previous Apple A8. Therefore, the performance should be on par with high-end Android SoCs in 2015.

It is based on the third generation of Apples 64 Bit architectures (Cyclone 3?) and uses a "new transistor technology". It is manufactured at Samsung in 14nm (slightly smaller die) and TSMC at 16nm (both FINFET 3D transistors). A performance difference of both versions are not noticable.

Furthermore, the chip now integrates the M9 motion coprocessor and a 4K video de- and encoder (as the iPhones 6s supports 4K video recording). The integrated graphics card should be still based on PowerVR technology.

The power consumption could be lower than the A8 due to the new process technology and the fact that the iPhones now got a smaller battery (due to the haptic engine part).

Samsung Exynos 9611

The Samsung Exynos 9611 (or Exynos 7 Series 9611) is a mid-range SoC for Android based smartphones and tablets. It integrates 8 processor cores in two clusters (bigLITTLE concept). Four ARM Cortex A73 cores at up to 2.3 GHz for demanding tasks and four ARM Cortex A53 at up to 1.7 GHz for power efficiency. Compared to the older Exynos 9610, the 9611 supports higher resolutions for the rear faced camera.

The integrated LTE modem supports 4G at up to 600 Mbps download and 150 Mbps upload. Furthermore, 802.11ac WiFi and Bluetooth 5.0 are also integrated in the chip.

The on-board ARM Mali-G72 MP3 graphics card offers three clusters and support for Vulkan, DirectX 12 and OpenGL ES 3.2.

The Exynos 9611 is manufactured in the modern 10nm FinFET process and therefore relatively power efficient and also suited for smaller smartphones.

Apple A9X

The Apple A9X is a high-end ARM SoC (System on a Chip) that was announced in September 2015 in the iPad Pro. Technical details are scarce, what we know is that it is based on the third generation of Apples 64 Bit architecture (Cyclone 3) and manufactured with a "new transistor technology" (14 or 16nm FINFet probably).

The performance of the A9X did improve a lot according to Apple. The CPU part should be 1.8x faster and the GPU part even 2x faster than the already speedy Apple A8X. Apple even stated in the keynote of the iPad Pro that the performance should be "faster than 80% of portable PCs shipped in the last 12 month". Furthermore the iPad Pro now features a 2x higher memory bandwidth (DDR4?) and 2x faster storage performance. The integrated graphics card will most likely be a PowerVR design again (Power VR Series7?).
