The Qualcomm Snapdragon 845 Mobile Platform (or SD845) is a high-end SoC for smartphones that was introduced in early 2018 and manufactured in 10 nm LPP FinFET at TSMC. Integrates 4x Kryo 385 cores (Cortex-A75) at up to 2.8 GHz (max) for performance and 4x Kryo 385 at 1.8 GHz (max) for efficiency. Furthermore offers an X20 LTE modem (Cat. 18 1.2 Gbps downlink, Cat 13 150 Mbps uplink), ac-WiFi and a dual-channel 32-Bit 1866 MHz LPDDR4x memory controller.
The Tensor G3 marks the third generation of Google's own chipsets for smartphones and tablets based on Android. This SoC is used for the first time in the Pixel 8 and Pixel 8 Pro and Google sees the SoC as a high-end device.
The CPU of the Tensor G3 is composed of three clusters. The first houses a single powerful Cortex-X3 core, which can operate at up to 2.91 GHz, the second offers four performance cores (Cortex-A715) with up to 2.37 GHz and the third cluster has four efficiency cores (Cortex-A510) with up to 1.7 GHz. The clock speeds are therefore not particularly high, so that the pure CPU performance is more on the level of an upper-middle-class SoC.
An ARM Mali-G715 is used as the graphics unit. Google is silent about the exact number of cores, but the benchmarks and the lack of ray tracing suggest a version with seven cores (G715MP7).
The core of the Tensor SoCs is the Tensor Processing Unit (TPU), which is responsible for AI and ML tasks. Here, too, Google owes the public more precise information and only talks about the fact that 150 times more complex AI models can be calculated on the device.
In addition, Google integrates its isolated security core subsystem, which again uses the Titan M2 co-processor and provides additional protection for its own data on a hardware basis. The G5300i modem is based on the Exynos 5300 and supports Wi-Fi 7.
The Tensor G3 is manufactured in the current 4nm process at Samsung.
