The Galaxy A56 is less than six months old at this point, having debuted at the beginning of March alongside the cheaper Galaxy A36 (curr. $374.99 on Amazon). Nonetheless, early information about a potential Galaxy A56 successor emerged this spring.
To recap, GalaxyClub revealed in May that Samsung intends to release the Galaxy A57 with its in-house Exynos 1680 chipset. Now, what appears to be a prototype running that chipset has surfaced on Geekbench. For the time being, only a single OpenCL score has been listed, evidence of which we have embedded below.
In short, the listing 'Samsung Electronics Co., Ltd. Full Android on S5E8865 ERD' clearly relates to 'S5E8865', the codename for the Exynos 1680. Based on the information that can be gleaned from the listing, the Exynos 1680 has 8 CPU cores split into three clusters, just like its predecessor. We would not take too much notice of the CPU clock speeds though, given that all but Cluster 2 are way down on the Exynos 1580.
Meanwhile, the same listing also indicates that the Exynos 1680 features an Xclipse 550 GPU as GalaxyClub reported in May. At this stage, Geekbench reports that the GPU has 2 Compute Units (CUs) compared to the four found inside its predecessor. Regardless, the prototype nearly matches the Xclipse 540 when it comes to GPU performance in OpenCL. At this stage, Samsung's recent release schedules would suggest this is a prototype Galaxy A57 unit or a development board. There is no indication that an earlier expected launch is on the cards just yet, though.
