Mobile gaming is not a PC upgrade in pursuit of the maximum number of frames per second: what you bought is what the game is about. And when the beloved PUBG starts to shamelessly slow down and the battery asks the outlet after half an hour, there are few options – to put up with the problem or run for a new gadget. Against this background, the announcement of GPU Turbo technology sounded like fantasy . Is a software update really can improve the performance of the gadget and reduce power consumption? To answer, we tested the Honor Play smartphone supporting GPU Turbo.
GPU Turbo – what is it and what does it eat
Technology GPU Turbo presented in June 2018. This software update, the developers assure, increases the performance of graphics chips up to 60% and reduces energy consumption during gaming up to 30%. But how exactly?
The essence of the method is not to load the graphics processor with extra work when drawing the image. If there are static elements on the screen that do not change from frame to frame, but only the angle of view of them varies, it is not advisable to render them again. GPU Turbo creates such interaction between software and GPU, that the graphics processor can determine the nature of the scene and the dynamics of the picture. Therefore, it draws only changeable elements without spending a resource on the same task. So it turns out a stable high FPS and saves battery charge.
Honor smartphones, for which an update with GPU Turbo will be released soon or has already appeared
Since we are talking about the interaction of the processor with the software, two points are obvious. First, the technology was created only for HiSilicon Kirin chips. In the case of Honor Play, we are talking about the 970th model, the graphics processor of which is the Mali-G72 MP12, a 12-cluster GPU with a clock frequency of 850 MHz. It supports all current graphics APIs, including OpenGL ES 3.2, OpenCL 2.0, Vulkan 1.0 and DirectX 12 FL11_1.
Secondly, the CPU must receive information about the image from applications in order to learn how to identify static and repeatable elements and predict their presence or absence. That is, the technology must be embedded in the game itself. At the time of launch, according to official information, only PUBG and Mobile Legends: Bang Bang supported the GPU Turbo . Accordingly, we will study their behavior on Honor Play. We will also launch the fresh Asphalt 9 , the graphics of which impressed industry experts .
GPU Turbo in action: we start games
Of course, all the picture settings in each hit are twisted to the maximum values and we turn on the FPS counter. Let’s start a test drive with the “royal battle.”
In PlayerUnknown’s Battlegrounds we get an average of about 40 frames per second – the maximum figure for the game. When landing from an FPS aircraft, it can sag up to 25 due to the large amount of graphics for processing, small friezes are noticeable. On the ground, the situation is stabilized, occasionally the fighter produces 30 frames / s, but only for a few seconds, with a quick return to the original indicator. This is noticeably different from gaming on smartphones that do not support GPU Turbo: there FPS sags more often.●
Mobile Legends: Bang Bang at maximum speed does not cause the slightest criticism. The colorful hit, filled with various special effects, never slowed down and confidently held 60 FPS. The load on the CPU was almost absent. The main image processing was carried out by the graphics processor. Accordingly, we can conclude that the GPU Turbo for this game is really effective.
The same can be said about power consumption: minus 17% per hour is a modest figure for such a clever picture. The maximum temperature of the battery was only 38 degrees for the entire testing period – also an excellent indicator.
By the way, the GPU Turbo technology accompanies a nice bonus: there is vibro-impact, as when playing on gamepads. For example, when you start PUBG, the gadget vibrates when a bullet hits a character, and in Mobile Legends – with particularly strong attacks.●
Asphalt 9 GPU Turbo also shows good results: even at maximum settings, the device keeps a stable 30 frames per second. Although there is still a load on the CPU, this does not affect the sensations from the game.
More than four hours of play from a single charge is a very decent figure for a race full of special effects to the eyeballs. Maximum battery temperature – within 40 degrees.
Increasing the average or maximum FPS is not the only thing that GPU Turbo does. The frame rate does not jump at a sharp change of the picture, but remains smooth. In those cases when the graphics processor is responsible for processing the data, the autonomy increase is clearly noticeable: you really believe in the stated 30% saving of charge. In short, GPU Turbo is a rare case when a software update is not a bluff of PR people, but actually improves the performance of a smartphone.
