ARM's newest Mali-G78 GPU has been tested alongside the Kirin 9000 on a Huawei Mate 40, and the results look alarming. Although the GPU manages to hit 1 TFLOPS under peak load, the accompanying power consumption can go as high as 14W. Its average power usage seems to be around 9W.

The Kirin 9000 and Exynos 1080's impressive AnTuTu score painted a pretty picture of the ARM Mali-G78 MP24. The flagship GPU can, at least on paper, take on Qualcomm's Adreno 660. However, it seems to be quite a power hog, based on some tests conducted on the Huawei Mate 40.

Ice Universe Tweeted what looks like a GPU power test run on the Mali-G78. The GPU purportedly guzzles up to 14W at full load and about 9W on average. The number is quite high for a mobile GPU, but it is somewhat understandable, considering that it has 24 cores. However, we have to treat these results with a healthy dose of skepticism. The Huawei Mate 40 in question is very likely a pre-production unit running unstable firmware, and we should wait for it to hit the shelves before making any judgments.

It'll be interesting to see how Samsung cools the ARM Mali-G78 on its upcoming Exynos 1080 and Exynos 2100 devices. Bad thermal performance has been the bane of Exynos' existence for quite some time now, and the Mali-G78 won't make things better. Unfortunately, Samsung has no choice but to use ARM's GPUs, as its in-house AMD Radeon-powered unit is far from ready.

I've been an avid PC gamer since the age of 8. My passion for gaming eventually pushed me towards general tech, and I've been a stereotypical 'nerd' ever since. I have a degree in mechanical engineering and have worked in the manufacturing industry. When I'm not writing news on Notebookcheck, you can find me playing or watching an intense match of DOTA 2
