Meet the Contenders: S905X5 vs Z1 IPTV
What is the S905X5?
The S905X5 is Amlogic's latest System-on-Chip (SoC), built on a cutting-edge 6nm process with ARMv9 Cortex-A510 cores. It delivers over 40,000 DMIPS—nearly double the performance of the previous S905X4 generation[reference:0]. The chip also includes a dedicated NPU (Neural Processing Unit) with 3.2 to 4 TOPS, enabling AI Super Resolution (AI-SR) for upscaling lower-resolution IPTV streams to near-4K quality[reference:1].
Devices powered by the S905X5, such as the Ugoos AM9 and BuzzTV Classic AI, are considered premium IPTV boxes in 2026[reference:2].
What is the Z1 IPTV Box?
The Z1 IPTV box is a budget Android TV device powered by the Allwinner H313 quad-core processor (Cortex-A53) with Mali-G31 GPU[reference:3]. It typically comes with 1GB to 2GB RAM and 8GB to 16GB storage, running Android 11 or Android 13[reference:4][reference:5].
While marketed as an "8K" box, the Allwinner H313 is a low-end processor that cannot handle true 8K decoding. Its "8K" claim refers only to the display output resolution, not actual 8K video processing capability[reference:6].

💡 The Reality Check: The S905X5 is 10x more powerful than the Allwinner H313 in the Z1 IPTV box. The performance gap is not incremental—it's generational. The Z1's "8K" label is misleading marketing; it can output a 4K signal but cannot decode true 8K content.
8K Streaming: The Truth About Both Devices
S905X5: True 8K Capable
The S905X5 supports native 8K decoding at 60fps and includes support for H.266 (VVC) and AV1 codecs—the compression standards required for efficient 8K streaming[reference:7]. It also supports HDMI 2.1b with features like Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM), ensuring smooth playback on 8K displays.
Z1 IPTV: 4K Only (8K is Marketing)
The Z1 IPTV box uses the Allwinner H313, which is limited to 4K@60fps decoding with H.265 support only[reference:8]. It cannot decode H.266 or AV1, and it lacks the processing power for true 8K video. When you see "8K" in the Z1's product description, it simply means the device can output a signal to an 8K TV—but the video itself will be upscaled 4K or lower[reference:9].
IPTV Performance: What Really Matters
For IPTV users, raw specs are only part of the story. What matters most is real-world streaming performance—specifically, how well the device handles high-bitrate streams without buffering.
S905X5: Built for Buffer-Free IPTV
Benchmarks indicate that devices equipped with the S905X5 and at least 4GB of LPDDR4X RAM maintain consistent sub-50ms jitter when processing H.265/HEVC streams via IPTV middleware[reference:10]. This translates to:
- Zero buffering even during peak hours
- Fast channel switching (under 1 second)
- Smooth EPG navigation without lag
- AI upscaling for 1080p IPTV feeds to near-4K quality
Z1 IPTV: Basic Performance Only
With only 1-2GB RAM and a low-end Allwinner H313 processor, the Z1 IPTV box struggles with demanding IPTV tasks. Users report:
- Buffering during high-demand live events
- Slow channel switching (3-5 seconds)
- Laggy EPG navigation
- No AI upscaling—1080p streams stay at 1080p
- Frequent app crashes due to insufficient RAM
⚠️ Important: A user review of the Z1 Mix box (powered by Allwinner H313) noted that the "2GB RAM and 8GB ROM is not enough to enjoy a video" and recommended at least 4GB RAM and 32GB storage for smooth IPTV performance[reference:11].
Price vs Value: What Are You Really Paying For?
| Device | Typical Price | What You Get |
|---|---|---|
| S905X5 Box | $80 - $150 | True 8K, AI upscaling, WiFi 6, 4GB+ RAM, Android 14, buffer-free IPTV |
| Z1 IPTV Box | $25 - $50 | 4K output only, no AI, WiFi 5, 1-2GB RAM, Android 11/13, basic IPTV only |
The Z1 IPTV box is cheaper, but you get what you pay for. For casual users who only watch occasional 1080p content, it might suffice. But for anyone serious about IPTV—especially those who want to watch live sports in high quality—the S905X5 is the only choice.

Setting Up Your IPTV Box for 8K Streaming
Once you've chosen your device, follow these steps to optimize it for 8K IPTV streaming:
1. Use Ethernet, Not WiFi
A wired connection eliminates the variability that causes buffering during high-bitrate streams. Even with WiFi 6, Ethernet is more stable.
2. Enable Hardware Decoding
In your IPTV player (TiviMate, IPTV Smarters), go to settings and enable Hardware Decoder. This offloads video processing to the GPU, reducing CPU load and improving performance.
3. Increase Buffer Size
Set your buffer size to "Very Large" or 10-15 seconds. This pre-loads more video data, smoothing out temporary speed drops.
4. Use a VPN to Prevent ISP Throttling
Many ISPs intentionally slow down streaming traffic. A VPN encrypts your traffic, preventing throttling and ensuring smooth playback.
5. Set Correct Resolution
In your device's display settings, ensure the output resolution is set correctly. For 8K, select 7680x4320. For 4K, select 3840x2160.
