MagyarGoogle Tensor G2: Chipset details revealed following Pixel 7 and Pixel 7 Pro launches
Yesterday, Google presented the Tensor G2, a chip that powers the Pixel 7, Pixel 7 Pro and next year's Pixel Tablet. While Google's product pages reveal little about the Tensor G2, XDA Developers has outlined the changes that Google has included from last year's Tensor. As expected, some changes are minor, while others should deliver a few performance improvements.
On the one hand, the Tensor G2 has the same tri-cluster CPU core arrangement as its predecessor. Likewise, this year's Tensor SoC retains its predecessor's two Cortex-X1 and Cortex-A55 CPU cores, with the latter remaining at 1.8 GHz. Conversely, Google has overclocked the two Cortex-X1 cores by 50 MHz to 2.85 GHz, arguably the definition of a minor change. With that being said, the Cortex-A76 cores running at up to 2.25 GHz have made way for Cortex-A78 cores clocked at 2.35 GHz.
On the other hand, the biggest change between Tensor and Tensor G2 appears to lie in GPU performance. To recap, Tensor utilises the Mali-G78 MP20, a GPU with four fewer cores than the Mali-G78 MP24 found in the HiSilicon Kirin 9000. In comparison, Tensor G2 features the Mali-G710 MP07, likely a 7-core version of the Mali-G710 MP10 found in the Dimensity 9000. According to our database, the Mali-G710 MP10 delivers 1.64x the benchmark performance of the Mali-G78 MP20. In other words, the Tensor G2 should offer significantly better GPU performance than the outgoing Tensor, even with three fewer GPU cores than the Dimensity 9000.
Google has made other changes as well, such as a revised ISP and an improved TPU. Reputedly, the new TPU is simultaneously 20% more efficient than its predecessor and 60% more powerful, although we would recommend awaiting independent reviews before trusting those figures. The Pixel 7 and Pixel 7 Pro will begin shipping on October 13; you can read more about both devices in our corresponding launch articles, along with the long-awaited Pixel Watch too.
