We didn't have a chance to test the tablet, but we saw a running prototype with Android 5.1. The company claims that the SoC will be ready for customers in July, which is just a month away. The prototype tablet felt quite mature and Android 5.1 runs well, at least when it comes to the user interface and usual Android tasks.
The score is not bad considering that you need an eight core MT6595 with four 2.2GHz clocked Cortex-A17 cores to score 51k, while the or HTC One M9 with Qualcomm’s Snapdragon 810 can score close to 54K in the same test. Have in mind that both these chips have eight cores and that the MT8173 has two big A72 cores at 2.0GHz, backed by two small A53 cores clocked at 1.6GHz.
This gives you quite good idea how the Cortex-A72 might perform compared to the Cortex-A57s we saw in the flagship SoCs in 2015.
