Google Tensor G4 that powers Pixel 9 series is a minor upgrade over Tensor G3 with new modem: Report

Google is gearing up to launch the Pixel 9 series later this month, with nearly all details, including specifics and marketing materials, already leaked.

However, details about Google’s new processor, the Tensor G4, have been limited until now, revealing it as a minor upgrade from its predecessor, according to Android Authority.

Tensor G4 CPU Specifications (Expected)
  • The Tensor G4 CPU has a 4+3+1 core configuration.
  • It uses ARMv9.2 cores: Cortex-A520, Cortex-A720, and Cortex-X4.
  • Clock speeds are slightly higher than the previous model.

Despite the new cores, the Tensor G4’s multi-core performance may be similar to the Tensor G3 due to the removal of one core. The report indicates early Geekbench scores show approximately 11% improvement in single-core performance and around 3% in multi-core performance.

Google may have adjusted the core layout to improve cooling, with the new cores being more efficient and reducing power consumption, although the modem remains the main power consumer in Tensor SoCs.

Modem and Connectivity

The Tensor G4 pairs with the new Exynos Modem 5400, supporting satellite connectivity and offering up to 50% better power efficiency than the Exynos Modem 5300. However, some Tensor G4 devices might still use the older Exynos Modem 5300, potentially including the Pixel 9a.

GPU and Custom IP Blocks

The Tensor G4 maintains the Mali-G715 GPU from the Tensor G3, now clocked at 940 MHz (up from 890 MHz). The report notes that Google’s custom IP blocks—Edge TPU, GXP, BigWave, and Titan M2—remain unchanged in the Tensor G4.

Additionally, the chip continues to use Samsung’s FOPLP packaging technology, contrary to earlier rumors of an upgrade to FOWLP.

Development and Prototypes

Initial plans for the Tensor G4 included a fully custom chip codenamed “redondo,” independent of Samsung. However, due to missed deadlines, Google collaborated with Samsung to produce a minimal upgrade codenamed “zumapro.”

The Pixel 9 series development used Tensor G3 prototypes to speed up the process, as seen in early leaks of the Pixel 9 Pro Fold running on Tensor G3, the report added.

With that said, the Tensor G4 may not be a significant leap from its predecessor, but it does bring some improvements, such as a new modem. The minor upgrades suggest that the new Pixel 9 features are software-based rather than hardware-driven.

We will see more details about performance and benchmark scores of the CPU when it launches on August 13 at the Made by Google event, where the company will also introduce the Pixel Watch 3.
