Amlogic S905X5 vs Amlogic S905X4: Features Comparison of Two Powerful TV Box SoCs

The world of TV box SoCs (System on Chips) has advanced rapidly, and Amlogic has been at the forefront of innovation. The Amlogic S905X4 was a significant step forward in media processing, but now, with the arrival of the Amlogic S905X5, the bar has been raised even higher. Both chipsets are designed for high-performance TV boxes and media streaming devices, but there are important distinctions between the two. In this article, we’ll compare the key features of the Amlogic S905X5 and its predecessor, the Amlogic S905X4, to help you understand how they differ and what they bring to the table.

1. Video Codec Support: AV1 vs. AV1 and H.266

Both SoCs support the AV1 codec, which has become the go-to standard for efficient video streaming, especially at 4K and 8K resolutions. The AV1 codec is known for delivering superior video quality at lower bitrates, a key advantage for content delivery on bandwidth-constrained networks.

However, the Amlogic S905X5 takes things a step further by introducing support for H.266 (VVC), the next-generation video codec that improves upon H.265 (HEVC). H.266 delivers up to 50% better compression efficiency, which allows for smoother playback of ultra-high-definition content (like 8K) while using significantly less data. This makes the S905X5 better suited for future-proof devices that require handling even larger media files with enhanced efficiency.

Key Difference: Both chips support AV1, but only the S905X5 supports H.266 (VVC), making it more advanced in video compression technology.

2. Ai-SR (AI Super Resolution)

The Amlogic S905X5 introduces Ai-SR (Artificial Intelligence Super Resolution), a cutting-edge feature designed to upscale lower-resolution content to near-4K or 8K quality using AI-driven algorithms. Ai-SR enhances image sharpness, improves detail, and minimizes noise, resulting in a clearer and more immersive viewing experience.

The S905X4 lacks this AI upscaling capability, which means it cannot deliver the same level of image enhancement, especially when dealing with lower-quality or standard-definition content.

Key Difference: The S905X5 has AI Super Resolution, offering superior upscaling and image enhancement compared to the S905X4.

3. Performance and Efficiency

Both SoCs use ARM Cortex-A55 CPU cores, which are known for their power efficiency and solid performance in media applications. They are coupled with Mali-G31 GPUs, which provide good graphics performance for tasks such as light gaming and user interface navigation.

However, the S905X5 benefits from optimizations in power consumption and performance efficiency, likely due to its more modern architecture and manufacturing improvements. These tweaks ensure that the S905X5 runs cooler and more efficiently, which is important for energy-conscious devices that prioritize long-term stability and performance.

Key Difference: While both SoCs use similar CPUs and GPUs, the S905X5 offers slightly better performance and energy efficiency due to architectural improvements.

4. Connectivity: Wi-Fi and Ethernet Support

The Amlogic S905X4 supports Wi-Fi 5 (802.11ac) and Gigabit Ethernet, providing stable and reliable network connections for 4K streaming.

On the other hand, the S905X5 comes with upgraded support for Wi-Fi 6 (802.11ax), the latest wireless networking standard that offers higher speeds, lower latency, and improved performance in crowded networks. This gives the S905X5 a significant edge in modern environments, where fast, uninterrupted connections are essential for smooth streaming and gaming experiences. It also continues to support Gigabit Ethernet for wired connections.

Key Difference: The S905X5 supports Wi-Fi 6, offering faster and more reliable wireless performance compared to the Wi-Fi 5 support in the S905X4.

5. Operating System Compatibility

Both the S905X4 and S905X5 are optimized for Android TV platforms, supporting the latest Android versions and delivering a seamless experience for apps, games, and streaming services. Both SoCs are also compatible with Linux-based systems, providing flexibility for device manufacturers and developers who want to build customized media platforms.

Key Difference: Both chipsets offer excellent OS compatibility, but the S905X5 may offer better future-proofing with support for newer Android versions and enhanced features.

6. 8K Video Output

While the S905X4 is capable of handling 4K resolution output at 60fps with HDR support, the Amlogic S905X5 steps up with 8K video output at 60fps, ensuring it can handle the most demanding content available today. The S905X5 also supports HDR10+ and HLG, delivering richer colors and improved contrast, making it a more suitable choice for high-end media devices.

Key Difference: The S905X5 supports 8K video output, while the S905X4 is limited to 4K.

Conclusion: Amlogic S905X5 vs. Amlogic S905X4

The Amlogic S905X5 is clearly a step up from the S905X4, offering advanced features such as H.266 (VVC) support, Ai-SR upscaling, Wi-Fi 6, and 8K video output. These improvements make it the better choice for future-proofing your TV box or media streaming device, especially as higher-resolution content becomes more common.

While the Amlogic S905X4 remains a solid choice for 4K streaming and offers good overall performance, the S905X5 is designed to handle the demands of next-generation media consumption, making it the superior option for users who want cutting-edge features and the best possible viewing experience.

For manufacturers and consumers alike, choosing the Amlogic S905X5 ensures that your device is prepared for the future of streaming and media technology.
