Huawei GPU Turbo, what is it and how does it work?

ByLinky Johnson 2019-05-28 486

Today I bring you one of those cases in which the "hype" (that is, the "autobombo") escapes from the hands of a manufacturer, in this case Huawei and its GPU Turbo.

GPU performance


Today I'm going to try to tell you what this "magic" technology is that, according to Huawei, allows us to have a better performance of our mobiles in demanding games, while lowering battery consumption and not warming up the processor so much. Almost nothing, right?


First of all, what's clear to us (which isn't much, really): GPU Turbo is based on software, not hardware. Perhaps that explains the variety of terminals, from the P10 Lite of a server to the P20 of our colleague Erlantz, that support it (at least, on paper).


Here's the download on my case. What should come next, the commented improvement in performance, does not appear anywhere; and, what's more, from the date of the download and until today (about 2 months), I could not find any Huawei user (despite having tracked forums, news, etc.) who told me about the benefits of the mentioned update.


So I kept looking. And finally I found an article in which the author, with much more access to the Huawei itself than the one who writes to you, managed to receive a detailed technical explanation about this software. To save you the translation and the technicalities: GPU Turbo is a learning system based on IA (Artificial Intelligence) by which, AND ONLY IN CERTAIN GAMES (AT THE TIME), your terminal, studying your way of playing and the requirements of the game, "learns" how many resources it needs at any given moment, being able to adjust the behavior of the terminal so that the experience is as fluid as possible, and maximizing the available resources.


So, as you can see, the idea is very interesting. And in what games does it work, you might ask?


game responce


Just so we understand each other: the AI behind GPU Turbo learns...but without haste, one game at a time. And, as you can see in the graph, one of the results of that learning is that the response of the game to our touches on the screen is made, according to Huawei, 36% faster.


And I say "according to Huawei" because, probably because it's a technology still in development, it's not easy to verify the data that the company provides. In fact, it is curious that, after the latest updates in EMUI 8 and 9, unlocking a bootloader and rooting a Huawei has become an almost impossible mission, thus nullifying the possibility of working with Benchmark tools that could shed some light on the actual performance of the technology.


The above mentioned AnandTech article takes an exhaustive look at the different Kirin-architecture terminals and how they are affected (or will be affected in the future) by GPU Turbo. For those of us who don't want to go that far, we are left with the following: in my modest opinion, GPU Turbo is an optimization technology that, being purely software, could be "sold" to any manufacturer; not only video game companies, but even mobile phone manufacturers looking for their terminals to have a higher performance result without having to develop a certain hardware (there are Google's photographic algorithms, even though they also have dedicated hardware). In addition, a technology that, in principle, is adaptable in that it "learns" and, therefore, is susceptible of including improvements simply by means of an update via OTA.


So a great concept, "inflated" with purely marketing interests, and today, with very few tangible results for the end user. With the enormous variety of terminals that Huawei (and Honor) have in the market, some thought for that world so diffuse and so fashionable of "gaming", it will be even more difficult to make comparisons "fair", which in turn will continue to facilitate that the "hype" continues selling.


From my humble P10 Lite, which dreams of receiving EMUI 9 (and Android Pie), I hope to be able to update this analysis soon with my own reliable data; and, of course, from the team of El Rincón Androide we encourage you to share your experiences with this elusive technology.
