My Nexus 5 has scored less than my HTC One which has Snapdragon 600.
I rooted my Nexus and ran Trickster mod to monitor the CPU load, CPU temp and CPU clock frequency.
I found that the standard kernel starts to throttle Snapdragon 800 SOC on Nexus 5 at 63°C, initially dropping to 1958 MHz (from 2265 MHz maximum) , then as temperature continued to rise up to maximum of 69°C it throttled further, 1728 MHz, and eventually dropping CPU to 1036 MHz.
Trickster mod doesn't display GPU clock rate on Nexus 5 standard kernel so I don't know if GPU is also throttling, however with such aggressive CPU throttling it does impact performance including video frame rates significantly.
What are your experience with this matter ?
