Why This Comparison Matters for IPTV Users
If you're shopping for a new Android TV box in 2026, you've probably noticed two dominant chips: the older S905X4 and the newer Amlogic S905X5. Both are made by Amlogic, both support 4K, and both claim to be great for streaming. So which one should you actually buy?
The answer is more important than you think—especially if you stream IPTV. The S905X5 isn't just a minor refresh; it's a generational leap that changes what's possible with a mid-range TV box.
📊 Quick Verdict
- ✅ Buy the S905X5 if: You want AI upscaling, true 8K decoding, H.266 support, and buffer-free IPTV.
- 💰 Buy the S905X4 if: You're on a tight budget and only need 4K streaming for casual use.

IPTV Performance: The Real Difference
For IPTV specifically, the S905X5 offers three major advantages that the S905X4 simply cannot match:
1. AI Super Resolution for Sharper Streams
Most IPTV feeds still broadcast in 1080p. The Amlogic S905X5's integrated NPU enables AI Super Resolution, which uses machine learning to upscale 1080p streams to near-4K quality in real-time. The S905X4 has no AI processor, so your streams stay at 1080p.
2. Future-Proof H.266 Support
H.266 (VVC) is the successor to H.265 and can cut file sizes by up to 50% while maintaining quality. IPTV providers are beginning to adopt it, and the S905X5 is already compatible. The S905X4 will be left behind.
3. Buffer-Free 4K@120fps
The S905X4 caps out at 4K@60fps. The S905X5 handles 4K@120fps, which means smoother motion for live sports and fast-paced content. Combined with higher RAM support (up to 8GB), it delivers a noticeably smoother IPTV experience.
Which One Should You Choose?
✅ Choose the S905X5 If You...
- Watch a lot of live sports and want the smoothest motion possible
- Have a 4K or 8K TV and want to maximize its potential
- Want AI upscaling for sharper 1080p IPTV streams
- Plan to keep your device for 3+ years and want future-proof codec support
- Value fast app loading and smooth EPG navigation
💰 Choose the S905X4 If You...
- Are on a tight budget (under $60)
- Only watch casual 1080p/4K content
- Don't need AI features or H.266 support
- Already have an S905X4 device that works fine
