Update | The latest Pixel 4 Geekbench leak is the most confusing yet
Update: The well-known leaker Sudhanshu Ambhore has recently put this leak down as false. For the potential new Pixel buyer, this is probably for the best.
Back in February 2019, a device purporting to be the Pixel 4 appeared on Geekbench 4. However, as this device's results in these test indicated that it had only 2GB of RAM and an erroneous code-name suggested that it was not likely to be viable as a leak.
7 months later, the 4 has been confirmed to exist (along with its XL variant), and a new Geekbench listing is a slightly better sign that it is currently being tested prior to its launch. However, there are some caveats attached to this theory.
This set of results is entitled "Google Google Pixel 4", and proceeds to outline a device with 4GB of RAM on Android 10. A "motherboard" field is populated by the "sm8150", also known as the Snapdragon 855 processor that one might expect to see in a flagship from Mountain View.
Oddly, however, this version of the 855 is listed at a speed of 1.9GHz, whereas it typically goes at 1.785GHz in other 2019 flagships. This suggests that the chipset is in fact the updated 855 Plus version - however, its own base clock has been the same as that of its predecessor on other Geekbench listings, such as that probably associated with the Xiaomi Black Shark 2 Pro.
Alternatively, it is possible that Google has tweaked the Qualcomm processor to its own specifications. This idea, however, would not explain the markedly low scores the "Pixel 4" received in its alleged Geekbench test.
They consist of 1749 in single-core scores, whereas existing 855 and 855 Plus devices have managed about 3600 in the past. Furthermore, its multi-core results are 6135, whereas other 2019 flagships have reliably broken into 5 figures.
These suspicious results could be explained by instability and other issues in an early build of Android 10. Nevertheless, another earlier Geekbench leak, posted by a device code-named "coral" (also linked to the Pixel 4), that ran Android Q (the precursor to 10) managed respectable single- and multi-core scores of approximately 3200 and 9000 respectively.
In addition, the Pixel 4 line has been rumored to start at 6GB of RAM this year (a leak supported by the 'coral' results). Therefore, it is possible that this new set of benchmarking results is no more viable than those of the past.
