The Google Pixel 11 Pro suffered a sharp loss in performance during consecutive thermal stress tests on the AnTuTu benchmark. Testing revealed that the flagship smartphone experienced heavy thermal throttling under sustained loads, producing results weaker than expected for a flagship device.
The smartphone runs on Google's new 3-nanometer Tensor G6 chip. In its best test run, the device achieved a top overall score of 1,710,984 points, but graphics performance declined rapidly as operating temperatures increased.
Tech outlet Mobile-com reported that the graphics processing unit initially scored 414,765 points at a very low internal temperature. When the temperature reached 11.3 degrees Celsius, the graphics score fell to 226,111 points, representing a reduction of roughly 45 percent.
Performance dropped even more dramatically as heat built up further. At 36.7 degrees Celsius, the graphics unit scored just 40,362 points, which is less than 10 percent of its peak performance.
Benchmark testing and graphics degradation
The low score of 40,362 points places the graphics output of the Pixel 11 Pro near the level of older smartphones equipped with the Qualcomm Snapdragon 888 processor, which launched in 2021.
According to Mobile-com, test results indicate that the graphics processor is the primary bottleneck for the Tensor G6 under sustained workloads, as rising temperatures trigger severe throttling.
Tensor chips and device throttling
The Pixel line is Google's flagship range of Android smartphones, which compete directly with premium mobile devices from Apple and Samsung. Google designs custom Tensor system-on-chip processors for its Pixel lineup to manage on-device artificial intelligence, image processing, and general workloads. Semiconductor manufacturing processes measured in nanometers indicate transistor density, with 3-nanometer architecture representing cutting-edge fabrication designed to enhance efficiency and speed.
AnTuTu is a widely recognized mobile benchmarking application that evaluates hardware capabilities by stress-testing central processing units, graphics hardware, memory, and user interface responsiveness. Thermal throttling is a protective mechanism built into mobile processors to reduce clock speeds when internal heat reaches elevated thresholds, preventing permanent hardware damage while reducing performance during demanding tasks.
Qualcomm's Snapdragon 888 was a high-end mobile platform released for flagship smartphones in late 2020 and early 2021. Matching its graphics score during heated testing highlights a significant drop in power for a contemporary flagship smartphone under continuous stress.
