The Navi Flounder is believed to offer 40 Compute Units, just as many as Navi 10, but the memory bus width is rumored to be limited to 192-bit. This is not confirmed, of course, but it is a result of the simple multiplication of three variables present in the firmware data. Assuming that each Compute Unit carries exactly 64 Stream Processors, the Navy Flounder would feature 2560 unified cores.
