Sony Xperia Z3 outperforms the Z4 powered by the Snapdragon 810

We were just speaking of Qualcomm’s Snapdragon 810 in OnePlus’s announcement today that they will still be going with the embattled chipset (albeit claiming that it will be a new version of it, without the overheating, of course) with their upcoming flagship, the OnePlus 2. What now we have in this article is a simple real-world test of multitasking and app performance – the year-old Sony Xperia Z3 which sports the already dated but still highly capable Snapdragon 801, versus the new Sony Xperia Z4 with the Snapdragon 810.

The testing in the video below is far from scientific, but it does work for us in real world situations. Overheating in a mobile processor results in the chipset throttling the performance of the proc, thereby producing the lags in software and gaming performance that users absolutely abhor. The video was made in Vietnam, with a Z3 (left side, white) and a Z3+/Z4 (right side, black). The audio is in Vietnamese, but the video is kinda self-explanatory. Take a look below.

The testing method was simple. Both the phones were made to go through the same multitasking processes, mainly with gaming apps and use of the camera. As you can see, the beginning of the test shows both phones with negligible delays – although it is a testament to the Snapdragon 801 that it can basically stand with the 810 in a fair fight. As the apps started piling up, however, more and more processes were getting pushed to the processor – this is where heat starts to become a real issue. As you can see, around this point the Xperia Z3 started outperforming the Xperia Z4. The final result showed the Z4 finishing its task queue 7 seconds later than the Z3.

In real world scenarios, this kind of lag would be close to negligible. And the Snapdragon 810 is still a pretty fast chip, especially compared to the competition. Also, you would rarely push your devices to such punishment. But think about this – you are paying top dollar for a premium Sony Xperia device. You should not be getting this type of lag, if at all. And surely, a Z4 should not be outclassed and outperformed by a model a year older than it. Your thoughts?
