Google Pixel 7 and Pixel 7 Pro codenames discovered in Android 13 DP1 alongside a Pixel 6 Pro with a second-generation Tensor chip
Google is a while away from releasing the Pixel 7 and Pixel 7 Pro, especially considering that the Pixel 6 series is only a few months old. Instead, the company appears to be much closer to launching the Pixel 6a and Pixel Watch; both rumoured to be arriving in May at this year's Google I/O conference.
However, 9to5Google, with the help of @cstark_27, claims to have discovered references to the Pixel 7 and Pixel 7 Pro in the first Android 13 developer preview. Incidentally, Mishaal Rahman published details about Google's second-generation Tensor chip (GS201) in October, along with 'a base board or developer board' codenamed Cloudripper.
According to 9to5Google, GS201 relies on a modem with the model number 'g5300b', likely an unreleased part called the Exynos Modem 5300. Potentially, Samsung could already have used the Exynos Modem 5300 in the Exynos 2200, an SoC that powers the Galaxy S22 series in Europe and a few other markets. Samsung will begin shipping the Galaxy S22 series next week for reference.
9to5Google adds that Android 13 DP1 ties the Exynos Modem 5300 to 'Cheetah', 'Panther' and 'Ravenclaw', reputedly all smartphone codenames. 9to5Google believes that Ravenclaw is another development device though, rather than a device that Google intends to bring to market. The website suggests that Ravenclaw could be a portmanteau of Raven, the Pixel 6 Pro's codename, and claw, a nod to the Pixel 7 series' feline codenames.
Hence, 9to5Google deduces that Ravenclaw is a Pixel 6 Pro with a GS201. In effect, Ravenclaw is Whitefin's spiritual successor, a development device that combined the Pixel 5 and the GS101. The Pixel 7 and Pixel 7 Pro are not expected to launch until the autumn, possibly alongside Pipit, the codename for Google's first foldable smartphone.
