The evidence is piling up by the day that HTC and Google are preparing to launch a new pair of Nexus-branded handsets by the end of 2016. Yet, while most of the attention has been directed at Marlin – the larger of the two smartphones – a pair of benchmark test readouts have now reaffirmed earlier reports relating to the slightly smaller device called Sailfish.

With HTC reportedly on manufacturing duty for the Google Nexus-branded smartphones, leaks have been coming quick and fast, with recent reports claiming the duo are set to launch on 4 October.

A source "close" to HTC's Nexus project expanded on Sailfish in late June, sparking claims that the 5in smartphone will replace the similarly sized LG Nexus 5X in Google's 2016 line-up. The specs listed in that report have been further substantiated by an AnTuTu benchmark result leaked by reliable smartphone tipster Steve Hemmerstoffer, a.k.a OnLeaks.

The specification list – spotted by Hemmerstoffer on Chinese microblogging site Weibo – reaffirms that the Sailfish will run Android 7.0 Nougat out of the box, with Qualcomm's quad-core Snapdragon 820 chipset and the Adreno 530 GPU under the hood.

The 13 megapixel rear camera and 8 megapixel front camera, 4GB of RAM, 32GB internal storage and 1080p Full HD display listings also tally with previous reports, with only the 2770mAh battery, 5in screen size and USB-C support "unconfirmed" by the readout.

With a Geekbench listing also backing up the AnTuTu readings, the Sailfish picture has become fairly clear and is now lacking only a retail-friendly name to go and a finalised design to go with its leaked specs.

A recent render mock-up based on the leaks provided potential Nexus buyers with a peek at how both the Marlin and Sailfish smartphones could look. Speculation for the larger Marlin handset points toward a relatively similar specification list to the Sailfish – with the exception of its larger 5.5in QHD AMOLED display and a 3450mAh battery.
