Qualcomm Snapdragon S1 QSD8250 vs Amlogic AML8726-MX vs Qualcomm Snapdragon S4 Pro APQ8064A

Qualcomm Snapdragon S1 QSD8250

The Qualcomm Snapdragon S1 QSD8250 was one of the first Snapdragon SoCs for smartphones and tablets featuring a Scorpion CPU core, an Adreno 200 GPU and GSM/UMTS radio.

Amlogic AML8726-MX

The Amlogic AML8726-M is a cheap SoC (System on a Chip) for Android tablets and smartphones. It integrates two ARM Cortex-A9 cores (max. 1,5 GHz) with SIMD extensions and an ARM Mali-400 graphics card. Furthermore, the chip supports hardware decoding of 1080p videos according to Amlogic.

Qualcomm Snapdragon S4 Pro APQ8064A

The Qualcomm Snapdragon S4 Pro APQ8064A is a high-end SoC for Android smartphones and tablets, which was introduced in 2012. The chip integrates 4 CPU cores, which are based on the ARMv7-compatible, but by Qualcomm designed Krait architecture. This provides a much higher per-MHz performance than Cortex-A9 chips such as Nvidia's Tegra 3 or the Exynos 4412 from Samsung, but does not quite reach the performance of the Cortex-A15 (for example in the Tegra 4). The memory is accessed via 2 x 32 bit LPDDR2 at up to 533 MHz, which offers a bandwidth of 8.5 GB/s.

Thanks to a dedicated decoder, the SoC can accelerate 1080p video playback up to a frame rate of 30 fps. 3D photos are possible up to a resolution of 20 megapixels. In addition, the chip also integrates a wireless module with Bluetooth 4.0 and WLAN 802.11ac/a/b/g/n. Produced by TSMC in 28 nm (LP), the power consumption should be around 4 watts (estimated, depending on the clock speed).
