Google is rumoured to launch two new smartphones on 4 October that are said to be appearing in place of the 2016 Nexus devices.

The two devices were originally codenamed Nexus Marlin and Nexus Sailfish, but recent reports have suggested Pixel XL and Pixel is what they will launch as instead, losing the Nexus branding.

This is how the Google Pixel XL currently compares to the Pixel, based on the latest rumours.

The majority of the rumours point towards HTC manufacturing both the Google Pixel and Google Pixel XL. Based on the leaked images, it looks as though the two devices might be similar in terms of design and bear some resemblance to the HTC Desire 10 devices in terms of speakers and sensors.

The Pixel XL and Pixel are both expected to come with a mainly metal body, but with a third of their rears featuring a glass panel. The leaked images show a circular rear fingerprint on both devices and no camera bump. It is also thought neither will have Nexus or HTC branding, with both suggested to feature just a G for Google instead. 

The Pixel XL is claimed to be the bigger of the two devices being compared here. It is rumoured to be coming with a 5.5-inch display sporting a 2560 x 1440 resolution and AMOLED technology. This would deliver a pixel density of 534ppi.

The Pixel is said to be slightly smaller at 5-inches with a lower resolution of 1920 x 1080. If true, the Pixel would offer a lower pixel density of 440ppi, meaning it may not be the one to pick for those interested in VR and Daydream.

The Pixel XL is reported to be coming with a 12-megapixel rear camera, coupled with an 8-megapixel front facing camera. This would be the same resolutions as the Nexus 6P from last year, which delivered good camera results. Whether it will be exactly the same sensors however is currently unclear.

The Pixel is claimed to be coming with a 13-megapixel rear snapper and an 8-megapixel front camera. Given this is claimed to be the lower-specced device though, we would expect a similar difference between Pixel XL and Pixel as there was between the 6P and the 5X or at least the same as the Pixel XL rather than a higher resolution on the Pixel.

The 5X offered the same rear snapper, but dropped the front camera's resolution to 5-megapixels.

The Pixel XL is rumoured to be coming with the Qualcomm Snapdragon 821 chip, which is said to be a slightly enhanced version of the SD820. Reports suggest to expect 4GB of RAM, along with 32GB and 128GB storage options.

The Pixel is reported to feature the Qualcomm Snapdragon 820 under its hood, suggesting the Pixel XL will be slightly faster. The RAM is claimed to be the same at 4GB, but it sounds like there will only be a 32GB model for the Pixel. Neither is likely to offer microSD as Nexus hasn't ever in the past.

In terms of battery, the Pixel XL is rumoured to be coming with a 3450mAh capacity, while the Pixel is said to be smaller at 2770mAh.

It is no secret that Nexus devices debut the latest version of Android, meaning the same will apply for Pixel. The Android Nougat 7.0 software, as it is called this year, is already publicly available but it has been claimed the Pixel XL and Pixel will launch on 7.1, which will offer a different experience to what is currently out there.

Both devices will offer exactly the same user experience, with vanilla Android stealing the show. You can read all about Android Nougat and what to expect in our preview.

Based on the leaks, it looks like the Google Pixel XL will be the more powerful of the two handsets being compared here, even if they both offer a similar design.

Currently, assuming the leaks are accurate, Pixel XL trumps Pixel in terms of display size and resolution, battery capacity, processor and storage capabilities. However, the big difference will be price. As with the Nexus 5X and Nexus 6P, we expect Pixel XL to challenge flagships, while Pixel presents a slightly more affordable device.

This may all change nearer launch though and we will be updating this feature, as well as our Pixel and Pixel XL rumour round up as we hear more so keep checking back for the latest.
