Amlogic S905X2 vs S905X3: Performance


Amlogic S905X2 and S905X3 are somewhat similar to each other regarding overall performance. Both are capable of reaching up to 2GHz and the manufacturing process is only 12nm, but unlike Amlogic S905X2,

Amlogic S905X3 features four Arm Cortex-A55 cores. Cortex A55 has 15% to 20% performance improvement and simultaneously lower power consumption than Cortex A53.

This means that you’ll see better performance on an Amlogic S05X3-powered 4K Android TV box, including the shorter loading time of application, smoother UI and more.

Amlogic S905X2 vs S905X3: Memory Storage

In terms of memory & storage interface, they are compatible with JEDEC standard DDR3-2133 / DDR3L-2133 /LPDDR3-2133 / LPDDR4-3200 SDRAM. The difference is that S905X3s memory interface has improved with the new SoCs supporting DDR4 up to 3200 MHz.

As we know, Amlogic S905X3 features Cortex-A55 cores as well to deliver up to twice the performance compared to Cortex-A53 in memory benchmarks.

Amlogic S905X2 vs S905X3: Video Playback

In the video playback section, Amlogic S905X2 and S905X3 support full 4K decoding. Exactly, equipped with an up-to-date HDMI 2.1 interface, both of them can decode Ultra HD 4K video content at up to 75 frames per second for H.265, AVS2, and VP9, providing a fast way to send video and audio output.
Additionally, Amlogic S905X3 also adds an AI processor that is used for voice recognition in TV Boxes.

Overall, there hasn't a big difference between S905X2 and S905X3 except for the last one with cortex-A55 CPU and AI processor. Therefore, the cost of S905X3 will be higher than S905X2.
