The Samsung Galaxy Tab S6 is currently projected to gain successors sometime in the third quarter of 2020 (3Q2020). This premium tablet line is also rumored to get even more comparable to the iPad Pros with vanilla and Plus variants. The former is expected to feature 11-inch displays, whereas the latter may distinguish themselves with 12.4-inch panels and at least 1 5G version. They may both have 120Hz refresh rates into the bargain.
1 SKU of each may have appeared on a benchmarking website. They are the SM-T870 (which may be the plain Tab S7, as the Wi-Fi only S6 is the SM-T860) and the SM-T976B, a novel model number that could be part of the S7+ sub-series.
They are both described as running Android 10 using the Snapdragon 865 processor - which, as their putative predecessor had the 855, is plausible - and as having 6GB of RAM. This last might seem a little underwhelming in 2020, but is also where the Tab S6 started.
As to their performance, they have both broken 4000 in single-core Geekbench 4 scores and approximate 13000 each in multi-core terms. Therefore, non-Apple premium slate fans may end up happy with Samsung's possible upcoming plans for this market.
