Qualcomm Snapdragon S4 Pro APQ8064A vs JLQ JR510

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).

JLQ JR510

The JLQ JR510 is a lower mainstream SoC for (Android-based) smartphones and tablets by JLQ, a joint venture with Qualcomm and several Chinese companies.

The JLQ JR510 integrates eight ARM Cortex-A55 cores (similar to the Snapdragon 439) in two Clusters. 4 higher-clocked cores with up to 2 GHz and four power saving cores with up to 1.5 GHz.

The integrated graphics card is not an Adreno, but a ARM Mali G52MP1 (single cluster). Displays can be with resolutions up to 1080p/60Hz, for 720p 90 Hz is possible.

The JR510 also includes an AI accelerator with a theoretical performance of up to 1.23 TOPS. For connectivity, the SoC supports 4G (Cat4 / 7), Wi-Fi 5 (802.11ac), Bluetooth 5.0, FM and GNSS.
