Google Pixel 9 Pro series phones have 3GB of RAM dedicated to AI, with 13GB of actual usable memory

According to news on August 22, Google Pixel 9 series phones are designed to improve AI performance by allocating a portion of a larger memory pool directly to the latest AI features. Test results show that the Pixel 9 Pro series has reserved 3GB of memory for AI, and the actual available memory is 13GB.

1. AndroidAuthority analyzed the memory configuration and found that the Pixel 9 Pro series adopted a new memory allocation strategy.

2. Unlike the previous Pixel 8 series, the Pro series dedicates 3GB of memory exclusively to AI related apps and services.
3. This part of memory is marked as "Unevictable" and "MLocked" to ensure that it will not be recycled by the system or swapped to the storage device, thus improving the response speed of the AI function.
4. On the Pixel 9 Pro series, AI core applications and EdgeTPU services take up most of the reserved memory. The
5. AI core application is responsible for model management, runtime, security features, and more, while the EdgeTPU service manages the Tensor G4’s AI hardware.
6. The two services appear to share the same memory space to ensure that the AI processor can perform calculations efficiently.
7. It is understood that the benefit of reserved memory is that the Pixel 9 Pro series can provide a better AI experience.
8. AI The core application always resides in memory, and the TPU is able to quickly access the required data, resulting in faster response times.
9. Also, reserving memory specifically for AI functionality ensures that it runs stably when running other memory-intensive applications.
10. However, for those who rarely use Google’s AI features, the reserved memory may be a waste.
11. The actual available memory of the Pixel 9 Pro series is only 13GB, which is not a significant increase compared to the previous Pixel 8 series.
12. So, for users who focus on gaming performance and multitasking, this may be something to consider.
