Qt painting performance with 4 different embedded GPUs (Mali, Adreno, PowerVR)
Summer is approaching, Qt 5.12.2 is out and we wanted to again get concrete painting performance numbers on some lower end embedded SOC GPUs. The kind of chipsets which people are using for embedded devices in multiple places. If user interface contains dynamically painted elements and target is 60fps (or maybe 30fps), how much could you actually paint and which Qt technologies to reach out? To do this testing in easily approachable way, we grabbed 3 cheaper Android™ tablets with different GPUs for testing. Other option would have been different development boards, but those need a bit more setup time and time-to-market (or time-to-blog.. ;-) ) is important to all of us. We also wanted to give Qt 5.12.2 a go while it's hot. So let's first introduce the tablets & chipsets used for this testing: 1) Lenovo Tab 7 Essential, MediaTek MT8167D, GPU: IMG PowerVR GE8300 . This GPU is exactly the same which e.g. Renesas D3 uses, so if you are into automotives this GPU may be
