While Google executives boasted about the improved Tensor G4 chipset in the latest Pixel 9 series, a recent stress test revealed concerning results regarding its thermal efficiency. The top-end Pixel 9 Pro XL experienced throttling to 50 percent of its maximum performance, indicating possible thermal issues despite the inclusion of a vapor chamber to manage heat dissipation.
During the product launch, Google highlighted the enhanced raw and AI performance of the Tensor G4, along with impressive power efficiency. However, @callmeshazzam’s stress test on the Pixel 9 Pro XL paints a different picture, showing significant drops in performance cores and efficiency cores when under stress. This outcome is disappointing, especially for a flagship device priced at $1,099.
The test results bring into question the effectiveness of the vapor chamber in controlling the Tensor G4’s thermals, with performance degradation observed compared to the promises made during Google’s event. The comparison to MediaTek’s Dimensity 9300 chipset facing similar issues suggests that stress tests can push even the most power-efficient processors to their limits.
While the Pixel 9 Pro XL’s thermal throttling raises concerns, it is essential to consider external factors like ambient temperature that can influence a chipset’s performance. Future tests will provide a more comprehensive evaluation of the Tensor G4’s capabilities and determine if the Pixel 9 Pro XL justifies its flagship status and price tag.
Overall, the stress test results underscore the importance of thorough assessment and user feedback to validate claims made by manufacturers, offering a balanced perspective on the real-world performance of high-end devices.
