Smartphones

The below data was collected on a smartphone device. The performance of the smartphone was limited at different levels and a benchmark test was performed. Figure 4-1 shows that, as the GPU and CPU performance increases, the temperature of the smart phone also increases because of the increased clock rates. This shows that, as the processor approaches the thermal design point, throttling the device at a lower temperature can affect the benchmark score by around 2% per °C.
