Qualcomm is actively promoting the 5nm Snapdragon 888 chip, which promises significant advantages over the Snapdragon 865. Xiaomi was the first major manufacturer to launch an SD 888-based smartphone. Since the Mi 11 is already available in China, the phone’s first tests are already in place. And it looks like Qualcomm’s latest flagship SoC hasn’t been very efficient.
Various benchmarks for the retail version of the Mi 11 have been posted on Weibo, including Geekbench, GFXBench, AnTutu, SPECInt, 3DMark, PUBG: Mobile, and Genshin Impact. These results were collated and analyzed by the Golden Reviewer YouTube channel. And when it comes to performance, the Snapdragon 888 clearly shows a great boost over the Snapdragon 865 and even beats the Apple A13 Bionic in Geekbench.
But while raw performance is definitely better, Qualcomm seems to have achieved this at the expense of energy efficiency. In AnTuTu, the results show a sharp rise in temperature during the test – by 12 ° C with a 4% battery loss during testing. The decrease in charge may be expected, but most modern flagships show a temperature rise of only 4-5 ° C. For example, even the Mi 10 Pro does not exhibit such abnormal behavior.
The SPECint benchmark on the Cortex-X1 Big Core @ 2.84 GHz shows 26% better performance than the Cortex-A77 in the Snapdragon 865 at the same clock speeds, but the power consumption has increased to 3.35W – a whopping 65 %. Snapdragon 865 in single-core mode consumes only 2.03 watts, while the ill-fated Exynos 990 consumes 3.8 watts.
As for the other cores’ performance in the same test, the Cortex-A78 in the Snapdragon 888 clocked at 2.42 GHz offers a 7% performance increase over the Cortex-A77 in the SD 865. But the power consumption is again higher – 1, 88 W. That is 25% more than the 1.5 W of the SD 865.
Higher power consumption means more throttling. Simultaneously, the results in ordinary tasks, and not in benchmarks, may not be so bad. For example, the reviewer noted that in PUBG: Mobile, with HDR + settings, the phone consumed a current of 0.8 to 1 A and could constantly maintain a stable 60 fps without generating a lot of heat. The battery dropped from 86% to 77% after about 30 minutes of play. Based on these numbers, the total power consumption is between 3.2 and 4W, roughly the same as the Snapdragon 865.
The 3DMark Wild Life stress test also showed no noticeable improvement over the Mi 10 Pro. But Genshin Impact turned out to be too complex a game for Mi 11: the device warmed up in 10 minutes to 50 ° C, and the number of frames per second dropped from 60 to about 30 due to throttling.
Initial results do not seem to paint a rosy picture for Qualcomm’s latest SoC, particularly for the Mi 11. However, this may vary by device and could be improved over time with firmware and driver updates. It is also possible that the international version of Mi 11 will bring some improvements.
