Introduction: The TV Box Processor Landscape in 2026
The System-on-Chip (SoC) is the heart of any Android TV box. It determines everything from interface smoothness and app loading speeds to video playback capabilities and future-proofing. In 2026, two Amlogic processors dominate the conversation: the established S905X (and its variants) and the next-generation Amlogic S905X5.
The S905X series has been the workhorse of the Android TV box market for years. But the arrival of the S905X5 represents a fundamental shift—a true next-generation SoC engineered from the ground up on a new CPU microarchitecture and a cutting-edge manufacturing process [11†L20-L24]. This article breaks down the differences, benchmarks, and real-world implications to help you decide if upgrading is worth it.
📊 Quick Verdict
- ✅ Upgrade to S905X5 if: You want AI upscaling, H.266 support, better power efficiency, and future-proof performance for 4K@120fps content.
- ❌ Stick with S905X if: You only watch basic 1080p/4K content, are on a tight budget, and don't need advanced AI features.
Understanding the S905X Family: The Baseline
Before diving into the comparison, it's important to understand the S905X lineage. The original Amlogic S905X was a 64-bit quad-core ARM Cortex-A53 processor built on a 28nm process, featuring a penta-core Mali-450 GPU [2†L5-L7]. It supported 4K@60fps video decoding with H.265 and VP9 [2†L33-L36].
Later variants like the S905X4 brought improvements: a 12nm process, Cortex-A55 cores, AV1 hardware decoding, and HDMI 2.1 support [11†L14-L16]. The S905X4 became the standard for mid-range 4K streaming devices, offering reliable performance with efficient AV1 playback.
However, the S905X4 still lacked dedicated AI acceleration and was limited by its ARMv8.2 architecture and 12nm manufacturing technology [11†L32-L34].

Why the S905X5 Represents a True Generational Leap
The differences in the table above are not incremental; they represent a fundamental paradigm shift [11†L20-L24]. Here's why the Amlogic S905X5 is a game-changer:
1. Armv9 Architecture: The Future of Processing
The S905X5 is the first Armv9 processor designed for set-top boxes [7†L4-L5]. It features quad-core Cortex-A510 cores delivering over 40,000 DMIPS—nearly double the performance of the S905X4 [10†L19]. This translates to:
- Smoother Interfaces: No lag or stutter when navigating menus
- Faster App Loading: Apps open almost instantly
- Better Multitasking: Seamless switching between multiple apps
- Future-Proof Compatibility: Optimized for next-generation Android updates
2. 6nm Manufacturing: Cooler, Quieter, More Efficient
The S905X5 is built on a 6nm process (compared to 12nm for the S905X4) [1†L10] [10†L13]. This is not just a marketing point—it delivers real benefits:
- 50% Lower Power Draw: Devices run cooler and quieter [0†L26-L27]
- No Active Cooling Needed: Many S905X5 devices operate without fans
- Longer Lifespan: Less heat means less wear on components
- Better for Continuous Use: Ideal for IPTV streaming that runs for hours
3. AI Super Resolution: Smarter Upscaling
One of the most exciting features of the S905X5 is its integrated NPU (Neural Processing Unit) with 3.2 to 4 TOPS of AI processing power [7†L19-L20]. This enables AI Super Resolution (AI-SR), which uses artificial intelligence to upscale 720p and 1080p content to near-4K quality in real-time [7†L26-L29].
For IPTV users, this is revolutionary. Many IPTV streams are still in 1080p. With the S905X5, those streams will look noticeably sharper and more detailed on 4K TVs—without requiring a higher-bandwidth connection.
4. H.266 (VVC) Support: The Future of Video Compression
The S905X5 supports the latest H.266 (VVC) and AV1 video codecs [7†L15-L19]. H.266 is the successor to H.265 and can reduce file sizes by up to 50% while maintaining the same quality [7†L15-L18]. This means:
- Lower Data Usage: Stream high-quality video with less bandwidth
- Future-Proofing: Ready for next-generation streaming platforms
- Better Quality at Lower Bitrates: Perfect for mobile and satellite connections
5. 4K@120fps: Ultra-Smooth Motion
The S905X5 supports 4K video playback at 120 frames per second [7†L15-L19], compared to 60fps on the S905X4. This is a significant upgrade for:
- Sports Content: Fast-moving action is smoother and clearer
- Gaming: Lower input lag and smoother visuals
- High-Frame-Rate Movies: Some content is now being mastered at 120fps
Real-World Performance: Benchmarks and User Experience
Benchmarks confirm the S905X5's superiority:
- Geekbench 5: The S905X5M-J (a variant) shows a 41.5% improvement over the S905X4 in single-core performance [3†L7-L9]
- GPU Performance: The Mali-G310 V5 delivers 52 GFLOPS, more than double the 20.8 GFLOPS of the Mali-G31 MP2 in the S905X4 [3†L29-L30]
- Overall Responsiveness: Users report that S905X5 devices feel significantly snappier, with apps launching faster and menus scrolling more smoothly
💡 The Bottom Line: If you're coming from an older S905X device, the S905X5 will feel like a completely new experience—faster, smoother, and more intelligent.

Frequently Asked Questions
What is the biggest difference between S905X and S905X5?
The most significant difference is the architecture. The S905X5 uses ARMv9 (Cortex-A510), while the S905X uses ARMv8 (Cortex-A53/A55). This means the S905X5 is more powerful, more efficient, and supports AI features like AI Super Resolution.
Can the S905X5 handle 8K video?
While the S905X5 is primarily designed for 4K@120fps, it supports advanced video codecs like AV1 and H.266 that are used in 8K content. However, for true 8K output, you would need a higher-end chip like the S928X series [8†L27].
Is AI Super Resolution noticeable?
Yes, especially on larger screens (65 inches and above). AI-SR uses machine learning to intelligently upscale content, reducing artifacts and improving sharpness. For IPTV users, this is a game-changer for 1080p streams.
Do I need to upgrade from S905X4 to S905X5?
If your S905X4 device still works well and you're happy with its performance, you don't need to upgrade urgently. However, if you want AI upscaling, H.266 support, and better 4K@120fps performance, the S905X5 is a worthwhile upgrade.
What internet speed do I need for 4K streaming on S905X5?
For smooth 4K streaming, a stable internet connection of at least 25-50 Mbps is recommended, especially for high-bitrate content.
Conclusion: Is It Worth Upgrading in 2026?
The Amlogic S905X5 is not just a minor refresh—it's a true generational leap. The combination of Armv9 architecture, 6nm manufacturing, AI Super Resolution, H.266 support, and 4K@120fps playback makes it the most advanced mid-range SoC available for TV boxes in 2026.
If you're currently using an older S905X device and want smoother performance, better image quality, and future-proof features, upgrading to an S905X5-powered TV box is absolutely worth it. The improvement in day-to-day usability—from faster app launches to noticeably sharper upscaled content—is substantial.
However, if your current S905X4 device still meets your needs and you don't care about AI upscaling or H.266 support, there's no urgent need to upgrade. The S905X4 remains a capable 4K streaming processor.
Ultimately, the decision comes down to your priorities: if you want the best possible experience for IPTV, gaming, and future content, the S905X5 is the clear choice for 2026.
