Tell me more about this Realtek CPU
The RTD1619B is a SoC (system on a chip) developed by Realtek, a Taiwan-based company that specializes in the design of semiconductor solutions for a wide range of applications, including IoT, multimedia, communications, and more.
The RTD1619B is built on a 64-bit architecture, meaning it can handle 64-bit instructions and data and can address a larger amount of memory than a 32-bit CPU. It has 4 cores, meaning it can process 4 concurrent threads, and it operates at a clock speed of 1.7 GHz.
The RTD1619B is also equipped with a Mali-G51 GPU. Mali-G51 is a part of the Mali family of GPUs developed by ARM. It is a Bifrost GPU, which is the middle tier of ARM’s Mali GPU offerings and has a performance of 1.5 Gpix/s. It also included with NPU (Neural Processing Unit) which is able to perform 1.6TOPS of AI operations.
It’s likely that this SoC is targeted at embedded and IoT applications that require some level of real-time processing and AI capabilities, such as smart home devices, cameras, and other similar products.
RTD1296 vs RTD1619B
The RTD1296 and RTD1619B are both SoCs developed by Realtek, both with 64-bit architecture, and both with 4 cores. However, there are a few key differences between the two:
- Clock speed: The RTD1619B has a higher clock speed of 1.7 GHz compared to the RTD1296’s 1.4 GHz. This means that the RTD1619B will generally perform faster than the RTD1296 for tasks that rely heavily on the CPU’s processing power.
- GPU: The RTD1619B comes with a Mali-G51 GPU, while the RTD1296 comes with a Mali-T820 MP3 GPU. Both are developed by ARM, Mali-G51 is Bifrost architecture and have a performance of 1.5 Gpix/s, meanwhile, Mali-T820 is Midgard architecture and have a performance of 1.2 Gpix/s. In general, the Mali-G51 GPU has higher performance than the Mali-T820 MP3, thus the RTD1619B is better equipped to handle tasks that require graphics processing, such as video decoding and gaming.
- NPU: The RTD1619B comes with a NPU (Neural Processing Unit) that is able to perform 1.6TOPS of AI operations. This gives the RTD1619B an edge over the RTD1296 in tasks that require AI-related processing, such as image recognition and machine learning.
- Power consumption: The RTD1619B may have higher power consumption than RTD1296 because of it’s faster clock speed and additional functionality.
It’s worth noting that these are general comparisons, and the performance of each SoC can also depend on other factors such as the memory, storage, and specific implementation of the software.
What apps will not work?
DS120j Will have no Docker, Face or Object recognition.
DS118 has no Docker/Container Manager compared to DS124.

Conclusion
DS120j is the weakest NAS with 512MB memory which basically only allows to use it for file storage and backups. A little bit of multimedia (DLNA only). One thing at a time. Anything else will be a slow and painful experience.
DS118 (discontinued) Can do everything mentioned above. But you also get few extra things like ability to run Plex media server, have face recognition in Photo app.
DS124 has slightly faster CPU. I does everything mentioned above. It also gets a one extra which is Docker / Container manager. H265 might have weaker compared to ds118.
