It is really, really uncomfortable to hold while in this state.īy contrast, most other phones tend to have one single, relatively small spot with a peak temperature. The Chinese manufacturer uses the mostly metal outer shell of the phone as a huge heatsink, meaning that the phone heats up pretty much all around to a hand-burning 47 degrees. The definite stand-out in this department is the Xiaomi Black Shark 2. The only slight issue with this tactic being the abundance of nerve endings in said hands that don't feel particularly comfortable when exposed to heat. Your hands actually make a pretty good radiator as well. Surface temperature and comfortĪfter all taking the heat away from the chipset normally means it's transferred to the body of phone. After all just hand comfort can be an issue with prolonged gaming sessions and it's important to see how the different smartphones manage that. One final thing we wanted to examine before we wrap this up was surface temperature. GFX 3.1 Car scene (1080p offscreen) Phone The worst offender was last year's Pocophone F1, which lost nearly half of its performance once things started heating up. Meanwhile, those around them would see significant drops in their GPU perofmance, which would inevitably result in either dropped frames or decreased graphics quality. The Black Shark 2 and the nubia Red Magic 3 were the only phones that retained their performance after an hour of stress testing. This turned out to be the most major win for the gaming phones yet. This way we can see how the different chipsets and phones react to overheating from a GPU standpoint, even if the GPU is not the one necessarily putting out all the heat. So, as a compromise and a showcase of how much gaming performance you will be losing we ran the GFX Bench 3.1 Car test twice - once when the chipset was cold and again when it had reached its thermal threshold. The info is scarce and often logged in vastly different folders if at all so no easy, reliable and convenient graphs were available here. Unfortunately Android and most smartphone manufacturers are not particularly cooperative when it comes to letting you monitor GPU stats. That would mean performance and thermals all plotted out on a graph over time. To be as thorough and precise as possible we really wanted to monitor GPU activity in the very same manner we did for CPU. After all, we are discussing extreme and prolonged loads here so realistically gaming and sustained performance are the actual subject of this examination. GPU Shark can display for every GPU the clock speeds (GPU core, memory and shader processors), performance states (or PStates), GPU fan speed, and GPU/memory/MCU usage.Now that we've investigated the CPU thermal-throttling situation it's time to talk about GPUs. The application is only able to display important details about GPUs, and it cannot offer other hardware information. This could be only good news for all users who want to monitor the GPU without having to configure different parameters. Basically, it’s extremely easy to work with this application, since there aren’t any configuration settings included. This is a simple-to-use application that allows you to view all the GPUs by displaying them in a single window. GPU-Shark is a small software utility that can help you monitor the graphics processing unit for GeForce and Randeon graphic cards. GPU Shark offers a global view of all your graphics cards in a single window. GPU Shark is available for Microsoft Windows only (XP, Vista and Seven). GPU Shark is a simple, lightweight (290KB) and free GPU monitoring tool, based on ZoomGPU, for NVIDIA GeForce and AMD/ATI Radeon graphics cards.
