Pixel 11's Tensor G6 and Pixel 10's Tensor G5 still fall behind in performance per watt, testing shows

Recent evaluations of Google's latest hardware indicate a persistent gap in power efficiency. According to testing reported by Notebookcheck, the Tensor G6 found in the Pixel 11 and the Tensor G5 found in the Pixel 10 both fall behind in terms of performance per watt. This technical analysis focuses on how the hardware handles processing tasks relative to the energy consumed, suggesting that the iterative updates to Google's custom silicon have not yet closed the efficiency gap seen in other high-end mobile processors. Coverage of the Pixel 11 series is varied across several technology outlets, highlighting a mix of hardware and software experiences. While Notebookcheck focuses on the specific efficiency failures of the G6 and G5 chips, ZDNET reports on the user experience with the device's artificial intelligence.

Specifically, a week of usage with the Google Pixel 11 led ZDNET to change its perspective on Gemini for the better. Meanwhile, Android Central has analyzed the Pixel 11 Pro Fold, describing the device as a solid upgrade but noting that the manufacturer could have pushed the hardware further when compared to other foldables on the market. Understanding these trends requires a look at the evolution of the Tensor line from the G5 to the G6. The focus for Google has been the integration of Gemini and the refinement of the foldable form factor, as seen in the Pro Fold. However, the Notebookcheck findings indicate that the fundamental architectural challenge of performance per watt remains an issue.

This matters because efficiency directly impacts battery life and thermal management, which are critical factors for both standard smartphones and the more complex screen configurations of foldable devices. Future observations will likely center on whether Google addresses these efficiency deficits in subsequent hardware revisions or relies further on software optimization. The reports suggest a tension between the improved AI utility of Gemini, as noted by ZDNET, and the underlying hardware limitations identified by Notebookcheck. Observers will be watching to see if the 'solid' nature of the Pixel 11 Pro Fold's upgrades can overcome the efficiency shortcomings of the Tensor G6 chip in real-world, long-term usage scenarios.
