OnePlus 6T's model number shows up on Antutu, scores higher than the 6
The OnePlus 6T will be launched on October 29 at an event in New York city. Unlike its predecessor, the 6, it has been widely rumored to drop the conventional wider notch for a more novel 'teardrop' alternative. The 6T has also been confirmed to have an in-display fingerprint scanner and Android Pie (9.0) out of the box.
The 6T may have the model number A6013, which would be in line with other T variants from previous years. A phone with this model number has made it onto Antutu Benchmark. The results of the device's evaluation with this app shows that it has a screen 2340×1080 resolution. It is powered by the Snapdragon 845 with the Adreno 630 GPU, and has an 8GB/128GB configuration.
This, then, is not hugely different from the specs of the OnePlus 6. However, the 'A6013' scored 297,132 in Antutu's testing. This is about 10,000 more than that of the 6. It is not clear why this would be when both phones are powered by the same processor and will run the same software (Oxygen OS based on Pie) at the 6T's launch. It is possible that the 6T's version of the OS is simply better optimized. However, this is still largely based on speculation at this point.
