Amid speculations on the release date and specifications of the Google Nexus 5 (2015) aka the Nexus 5 2nd Generation, AnTuTu benchmark site has leaked score of the smartphone, hinting that it will be superior to Samsung's current smartphone, the Galaxy S6 and Motorola Nexus 6.

Google Nexus 5 (2015) is expected to be released in October or November by which time Nexus 6 will complete a year cycle in the market. Product Manager of Android Jamal Eason has said in a statement on Android Developers Blogspot that the release of Android M, which is expected to come with Google's upcoming device, is scheduled for this fall.

Interestingly, Nexus 5 (2015) has been placed above current top smartphones. According to a report by WCCF Tech (via Phone Arena), the device scored an incredible 85,530 points, which is much higher than 68,157 points scored by Samsung Galaxy S6, and 47,079 scored by Motorola Nexus 6. 

It was earlier reported that Nexus 5 (2015) would be powered by Qualcomm Snapdragon 810 processor, which in no way can beat Galaxy S6's Exynos 7420 in benchmarking test. So, the device could be powered by Qualcomm Snapdragon 820, if one is to go by the score of AnTuTu benchmark website.

However, WCCF Tech has reported that Nexus 5 (2015)'s scores on AnTuTu benchmark could be a fake, citing instances of smartphone-makers manipulating scores just to please industry watchers and gain publicity.

Google is expected to launch two Nexus devices - one to be made by LG under the codename "Bullhead" and believed to be called Nexus 5 (2015), and the other to be made by Huawei under the codename "Angler" and believed to be Nexus 6 successor, according to a report by Android Police

The search is tight-lipped on its upcoming device, but several reports have claimed that it will sport a 5.2-inch screen with 1,440x2,560 pixels, powered by a Qualcomm Snapdragon 810 processor, run on Android M, come packed with 3GB RAM, has a 13mp main camera and 2mp front snapper, and house a 2,700mAh battery.
