If you're getting into the world of TV boxes or media players, you've almost certainly come across the name Amlogic. This manufacturer has managed to position itself as the king of the mid-range thanks to its S905 processor family , which is essentially the engine that makes your TV smart without breaking the bank.

We're not talking about a single chip, but a whole line of SoCs designed for different user profiles. From those who just want to stream a series to those who want to build a powerful multimedia center with game emulation and 4K resolution, there's an S905 adapted to every need, balancing power consumption with quite decent performance.

To start with the basics, most of these processors are based on the ARM Cortex-A53 architecture , a 64-bit standard that has become the norm due to its efficiency. Depending on the model, we can find significant variations. For example, the standard S905 is the entry-level option, ideal for simple tasks, while the S905X takes a step up in graphics performance and software optimization, making it the key component in more modern devices.

When it comes to real power in the mid-range, the S905X3 reigns supreme. This SoC represents a significant leap forward by integrating 12-nanometer ARM Cortex-A55 cores , meaning it runs cooler and uses less battery power while delivering superior performance. Furthermore, it includes a Cortex-M4 processor with a neural network accelerator , enabling virtual assistants like Google Assistant to respond much faster.

Visually, this model is a beast. It uses the Mali-G31 MP2 GPU , which leaves the old Mali-450 far behind. Thanks to this, you can not only watch movies, but also enjoy playing titles like PUBG on medium settings without the image turning into a slideshow. Furthermore, it supports OpenGL ES 3.2 and Vulkan 1.0 , ensuring smooth visual effects.

Video and audio capabilities: Streaming paradise

What truly makes the S905 series shine is its video engine. The Advanced Video Engine Gen10 allows for 4K decoding at 60 fps and even supports 8K in some specific cases using players like Kodi. It doesn't fall short in terms of formats either, as it perfectly handles the H.265 and VP9 codecs , which are used by YouTube and Netflix to ensure great video quality without hogging your bandwidth.

Image quality is enhanced by support for HDR standards , including Dolby Vision, HDR10+, and HLG. This means colors are much more vibrant and blacks are deeper. As for audio, most of these boxes support Dolby Audio and DTS , enabling surround sound that transforms your living room into a small cinema.

Detailed technical specifications

  • Processor: Quad-Core ARM Cortex-A53 or A55 depending on the generation.
  • Graphics: Mali-450 MP4 GPUs in basic models and Mali-G31 MP2 in advanced models.
  • Memory: Compatible with DDR3 and DDR4 RAM, generally from 2GB to 4GB.
  • Storage: Supports 16GB, 32GB or 64GB eMMC, expandable via TF card.
  • Connectivity: HDMI 2.1, USB 3.0, Gigabit Ethernet and dual-band Wi-Fi ports.

Performance in emulation and gaming

For those who enjoy nostalgia, the S905 chips are a very well-rounded option. If you want to play PSP or Dreamcast games , the S905X3, X4, or X5 models are more than enough and will give you a smooth experience. However, let's be realistic: if you're looking to emulate PS2 or GameCube, this hardware falls short, and you'd need to upgrade to a much higher-end model.

In everyday use, the combination of 4GB of RAM with these processors makes multitasking feel seamless . You can switch from a streaming app to a web browser without the device restarting or slowing down, thanks to the Android kernel optimization they typically include.

This entire range of Amlogic processors offers a surprising balance between cost and power, allowing any user to transform their television into a smart hub capable of handling 4K video, light gaming, and streaming applications with remarkable energy efficiency, establishing itself as the most logical option for those seeking quality without spending a fortune.
