ZTE revealed two models under the Nubia brand a month ago, the Nubia Z9 Max and Z9 mini. Meanwhile the true flagship Nubia Z9 remains unannounced, and that is expected to change on May 6, when a launch event is scheduled.
The Nubia Z9 hasn't exactly been kept a secret though and showed up on a number of occasions sporting a near-bezelless design and a metal frame for enhanced durability. But while there was also some consensus on the specs, a new listing by Chinese regulator TENAA dropped the bomb claiming some unbelievable hardware.
The device, carrying a model number NX508J, is said to come with a CPU clocked at a whopping 3.5GHz. It doesn't stop there, and RAM is quoted to be the unheard of 8GB.
The Nubia Z9 was previously said to be equipped with the Snapdragon 810, which comes with Cortex-A57 cores, clocked at 2GHz, and Cortex-A53 cores, clocked at 1.5GHz, in an octa-core big.LITTLE configuration. Looking back to the Nubia Z9 Max, which was already confirmed to sport the S810 and is listed on TENAA with 3.5GHz CPU, you could conclude that the regulators have simply added up the clock speeds of both sets of cores.
Little explanation can be found in the amount of RAM though. In the datasheets, available online, it's not explicitly stated if Qualcomm's chip supports the 8GB, but we're also wondering if there's any actual practical sense in it at this point in time. What sounds most likely is that it's an error on the TENAA part.
A few other discrepancies with the specs established so far come in the camera department, where an 8MP/8MP duo is quoted in the listing. Both the Z9 Max and Z9 mini come with a 16MP main camera, and the Nubia Z9 is unlikely to be a step back. It's also not a dual rear camera arrangement as the accompanying images clearly show.
The microSD slot has also been dropped in favor of 32GB of internal storage, as opposed to the 16GB of the other two models. Another thing to point out is that display size is listed as 5.15 inches, which goes in line with the rumors of 5.2 inches, but resolution is quoted to be FullHD, and not QHD, as previously believed.
Obviously, a lot of questions remain unanswered, but with a launch date less than a week from now, the mysteries will soon be cleared.
