Introducing the Google Tensor G3 Chipset
The Google Pixel 7 and Pixel 7a introduced the Tensor G2 chipset based on a 5nm node. The Tensor G2 also powers the recently launched Pixel 7a and the upcoming Pixel Fold. Leakers have shared snippets of information regarding the next-gen Google-branded system on a chip (SoC), the Tensor G3, codenamed zuma. According to prominent leaker Kamila Wojciechowska, practically everything we need to know about the Tensor G3 has been uncovered, expected to power the Pixel 8 and Pixel 8 Pro later this year.
The CPU Cores of the Tensor G3
According to information from Wojciechowska’s sources at Google, the Tensor G3 will offer nine CPU cores (4+4+1), which will include four Cortex-A510 cores and four Cortex-A715 ones, followed by a solitary high-performance Cortex-X3 core clocked at 3.0 GHz. Although the addition of the second-gen Armv9 processor will undoubtedly boost Tensor G3 performance, it could still fall behind the Armv9.2 version announced recently.
Improved Support for Android Apps and Upgraded GPU
The Tensor G3 will allow 64-bit only apps out of the box, unlike Tensor G2 phones like the Pixel 7, which kept 32-bit libraries onboard. Also, the new Tensor G3 chip will supposedly use the Arm Mali-G715 (Immortalis) GPU, a decent upgrade from the seven-core Mali-G710 graphics unit.
AV1 Encoder and UFS 4.0 Storage Standard Support
Another feature of the Tensor G3 will be the AV1 encoder, enabling the Pixel 8 to provide it out of the box. This is courtesy of the latest BigWave block, an upgraded version of the “BigOcean” hardware video decoder block available on previous Tensor chips. The Google Tensor chip will support the UFS 4.0 storage standard, which will introduce significant improvements to data read/write speeds and is already available on some of the top flagships today.
An All-New Tensor Processing Unit (TPU) and Digital Signal Processor
The Tensor G3 also features an improved TPU and a new digital signal processor (DSP) referred to as GXP. The Tensor G3’s new GXP (callisto) will improve an already existing four core amalthea GXP from Tensor G2.
Unchanged Exynos Modem 5300, Slightly Modified Avatar
According to leaks, the Pixel 8 will most likely continue with the same Exynos Modem 5300 as in the Tensor G2 but with some slight modifications. The Tensor G3 chipset is expected to be based on the yet-to-be-announced Samsung Exynos 2300, which will utilize the South Korean manufacturer’s 3nm node. Wojciechowska reported back in September that the efficiency of this new chip should be comparable to TSMC’s 3nm process.
Conclusion
Google’s Tensor G3 offers promising new features and improvements compared to its predecessor, the Tensor G2, which was already a powerful chip in its own right. The Tensor G3 chipset’s upgrade in CPU cores, AV1 encoder, improved TPU, and GXP for high-quality image processing makes it an attractive option for the upcoming Pixel 8 and Pixel 8 Pro smartphones.
