Google's next Nexus devices are rumoured to be coming on 4 October, only it has been claimed they will be branded as Pixel rather than Nexus.  

The two handsets were originally codenamed Nexus Marlin and Nexus Sailfish, but more recent rumours, of which there have been plenty, have called them the Pixel XL and Pixel.

In light of this, we have put the rumoured specs for the Google Pixel XL up against the current Nexus 6P to see how they compare and what the differences are based on the speculation.

The Google Pixel XL is claimed to be the larger of the two new devices and rumours suggest it will be based on the HTC 10. The leaked images suggest there will be a fingerprint sensor on the rear like the HTC flagship, no camera bump and speakers at the bottom on the front.

Measurements and weight have yet to be suggested, but it looks like a primarily metal build will be present on the Pixel XL, with the potential of a glass panel on the rear covering the top third of the device.

The Nexus 6P, made by Huawei, features an all metal build and measures 159.3 x 77.8 x 7.3mm with a weight of 178g.It has dual front-facing stereo speakers and there is a circular fingerprint sensor on the rear. A black strip runs across the top of the back housing the camera lens and flash.

The Google Pixel XL is rumoured to be coming with a 5.5-inch AMOLED display with a pixel resolution of 2560 x 1440. If this is the case, the Marlin will have a pixel density of 534ppi.

The Nexus 6P has a display that's slightly larger at 5.7-inches. It is also AMOLED technology and it too has a Quad HD resolution for a slighty lower pixel density of 518ppi. It is protected by Corning Gorilla Glass 4.

The size difference in the two devices being compared here means the Pixel XL will theoretically offer sharper and crisper images compared to the Nexus 6P, assuming the rumours are accurate. That said, the difference isn't likely to be noticeable to the human eye.

We'd also expect the Pixel XL to feature Gorilla Glass 4 too.

Rumours suggest the Pixel XL will come with a 12-megapixel rear snapper, coupled with an 8-megapixel front camera.

The HTC 10 also features a 12-megapixel rear camera with an aperture of f/1.8 so perhaps the same sensor will be on board the Pixel XL if HTC is the manufacturer.

The Nexus 6P has a 12.3-megapixel rear camera with an aperture of f/2.0. The front camera is 8-megapixels with an aperture of f/2.4. There is a dual-flash on the rear of the Nexus 6P and IR laser-assisted autofocus.

The Google Pixel XL is said to be coming with the Qualcomm Snapdragon 821 chipset, supported by 4GB of RAM and either 32GB or 128GB of internal memory. We wouldn't be surprised to see a 64GB model too though.

The leaks also suggest there will be a 3450mAh battery capacity on board the Pixel XL, along with USB Type-C.

The Nexus 6P has the Qualcomm Snapdragon 810 processor with 3GB of RAM. It is available in 32GB, 64GB and 128GB model, none of which have microSD support. Nexus devices don't do microSD so don't expect that on the Pixel XL either.

A 3450mAh battery is on board the Nexus 6P and it was one of the first devices to arrive with USB Type-C.

The Google Pixel XL will arrive with Android Nougat 7.1, which is said to offer a slightly different experience to the version of Android Nougat that's already publicly available. Nougat sticks to the material design of Marshmallow but introduces more information in places like settings so users will have to dig around less.

The Nexus 6P launched on Android Marshmallow but it has been be updated to Nougat so the software experience between these two devices should be pretty similar. It has been claimed the new Pixel devices will have a new gesture for opening notifications using the fingerprint sensor however and it is not know if this will make its way onto older devices.

Based on the rumours, the Google Pixel XL will be slightly smaller than the Nexus 6P but still offer a premium design and improvements in hardware, including a faster processor, more RAM and a bigger battery capacity.

It looks like the camera resolutions of the Pixel XL could be very similar to that of the Nexus 6P though and the display resolution and technology also seems to be the same.

This is of course all based on speculation for now but we will update this feature and our Pixel and Pixel XL rumour round up as more leaks appear.
