The third known implementation of AMD's "Navi" generation of GPUs with RDNA architecture is codenamed "Navi 14." This 7 nm chip is expected to be a cut-down, mainstream chip designed to compete with a spectrum of NVIDIA GeForce GTX 16-series SKUs, according to a 3DCenter.org report. The same report sheds more light on the larger "Navi 12" GPU that could power faster SKUs competing with the likes of the GeForce RTX 2080 and RTX 2080 Super. (actually, based on spec it would be way faster than 2080) The two follow the July launch of the architecture debut with "Navi 10." There doesn't appear to be any guiding logic behind the numerical portion of the GPU codename. When launched, the pecking order of the three Navi GPUs will be "Navi 12," followed by "Navi 10," and "Navi 14."
"Navi 14" is expected to be the smallest of the three, with an estimated 170 mm² die-area, about 24 RDNA compute units (1,536 stream processors), and expected to feature a 128-bit wide GDDR6 memory interface.
The 350-400 mm² "Navi 12" is a whole different beast, with an estimated 64 compute units (4,096 stream processors). The big news in the 3DCenter.org report concerns its memory interface. AMD will stick to 256-bit GDDR6 memory with the "Navi 12," and probably dial up memory clocks compared to the 14 Gbps speed the "Navi 10" uses.

UPDATE: digging into it, looks like a speculation mostly based on Linux drivers for "Navi 12" have the same number of memory interfaces as released 5700 series.
