With the year coming to a close in the next month and a half, and Samsung having already released their last two smartphones for the year, consumers and the industry will be looking ahead to what Samsung has planned next for the smartphone market. In terms of big releases, this will undoubtedly be the Galaxy S7, the follow-up flagship to the popular Galaxy S6 and Galaxy S6 Edge. There have already been a number of rumors starting in regards to the yet unannounced device, including a possible unveiling in January, as well as a rumor that the upcoming phone will come equipped with a 20MP rear-facing camera sensor as opposed to the 16MP sensor found in this year's devices.
The latest rumors seem to revolve around questions of the display, toying with the possibility that Samsung may outfit the next-gen Galaxy S phone with a 4K resolution display. This wouldn't be the most outlandish thing to happen as Sony already have a phone with a 4K display, the Xperia Z5 Premium. Samsung is also rumored to offer a Premium, and standard version of the Galaxy S7, so it's entirely possible that a premium version could come equipped with a screen that carries a higher resolution. Keep in mind these are just rumors at this point.
In addition to a 4K display, another rumor cites the possibility that Samsung could utilize a 14-core GPU. This particular rumor is a little more thin, given that Samsung's own in-house processor, the recently announced Exynos 8890 comes paired with a Mali-T880 GPU that only carries 12 cores, and this is likely to be the chipset used inside of the Galaxy S7. Another rumor speculates the possibility of the Snapdragon 820 which comes paired with Qualcomm's Adreno 530 GPU being the chipset inside of the Galaxy S7, or that Samsung could split it between Qualcomm's offering and their own Exynos 8890. It's certainly unlikely that Samsung would go with a different chipset than either of these two, although not impossible. Where this rumor comes from is that Samsung will have a slightly more powerful version of the Exynos 8890 that comes with an additional 2 cores to complete the 14-core makeup. The Mali-T880 is said to have the capability to support up to 16 cores due to its scalable build, so this isn't an entirely impossible scenario, although it's still unclear until Samsung confirms either way about the existence of this alternate chipset.
