Let’s look at the silicon that makes this device tick. The H11S is built on a HiSilicon Hi3798MV200 processor – a 64-bit ARM Cortex A53 chip clocked at 1.6GHz, paired with 1GB of DDR4 RAM and 8GB of eMMC flash.
| Feature | Specification | | :--- | :--- | | CPU | HiSilicon Hi3798MV200 (Dual-core 1.6GHz) | | GPU | Mali-450 (supports OpenGL ES 2.0) | | RAM | 1GB DDR4 | | Storage | 8GB eMMC 5.0 | | Tuner | 2x DVB-S2X (Multi-stream / T2-MI ready) | | Max Resolution | 4K (2160p) @ 60fps, 10-bit HEVC/H.265 | | OS | Enigma 2 (OpenATV, OpenPLi, Pure2, etc.) |
The Verdict on Specs: 1GB RAM is the bare minimum for heavy Enigma 2 skins (like FHD skins). If you run only basic skins and plugins, it’s smooth. For heavy multitasking, consider the H11S 2GB variant.
The Good: The H11S moves away from the cheap, glossy plastic of the H9 series. The matte black metal chassis feels surprisingly dense and dissipates heat well. The front panel features a small, non-intrusive VFD display that shows time and channel info.
The Bad: The USB ports are cramped. If you plug in a bulky WiFi dongle, you will block the second USB port. Also, there is no power button on the rear; you must unplug the PSU to hard reset.
Verdict: 7/10. Functional, not flashy.
