Google Tensor G4 Suffers Over 50% Performance Drop in Throttling Test

Google's Tensor G4 chip faces performance issue on Pixel 9 Pro XL

In a test result conducted by the X user, it came out that the recently launched Google Pixel 9 Pro XL is having performance issue with its Tensor G4 Chip and has been observed to suffer significant performance degradation under prolonged high loads while there is no official statement from Google on this issue.

What did the Tensor G4 performance test reveal?

The X user revealed in his test that the Tensor G4’s performance drops by up to 50% during extended periods of 100% CPU load. The chip frequency began to throttle and reduced its frequency within three minutes of the test which led to a dramatic reduction in processing power

After the four minutes of test, the CPU began to drop at its highest frequency rate by up to 60%. While the peak performance is nearly 341 GIPS but it was recorded only 246.6 GIPS and dropped even more by 145.5 GIPS in extreme test (less than 43% of the its peak). However, after the initial drop, the chip’s performance seemed to stabilize

The Geekbench score test revealed that the G4 chip has a 1932 single core score and 4519 multi-core score. It shows a main core with 3.1 Ghz, three cores clocked at 3.6 Ghz and four cores efficient cores clocked at 1.95 Ghz but the test indicated that the Tensor G4 dropped to 1.32 Ghz, while the efficiency core dropped up to 579 Mhz.

Should you care?

It’s worth noticing that this performance test on its GIPS is not the only factor that results in low frequency. The performance test is currently affected in extreme tests e.g. – gaming and video rendering etc., while it barely affects normal everyday usage. Nevertheless, the initial findings raise concerns about Tensor G4’s ability to maintain consistent performance under sustained workloads.
