The document released by SK Hynix outlines what appears to be the company's end-to-end model, where the GPU is described as D32310 / 15, a term that we have already seen on other occasions and that was registered in the RRA this month.
Although it is not yet clear whether it will be owned by the Navi family, we do see that its performance is in a different league.
Navi or Arcturus? AMD is double the number of Shaders and CU
The specifications are as amazing as it looks like that card will be. And that this new GPU will break with all the innovations so far in AMD that mark the company's milestones, where if the features are completely true then the graphics card we saw over the last month that surpasses the RTX 2080 You are over 17% overweight, be true.
And the SK Hynix blazes are revealing 5120 Shaders, where they would obviously maintain their 64-bit composition per CU, as the data points show 80 CU All in all, or anything similar, repeat what AMD is currently on the market with its RX 5700 XT.
TMUs and ROPs are compatible, as they would have you 320 first units and 96 second, the statistics to consider. As if that wasn't enough, the cache would be increased to about 12MB, 3 times more than the Navi 10 XT.
Introduction of high performance HBM2e with 4096 pieces
Memory configuration is an important stage in the SK Hynix, because AMD will be able to access the new HBM2e company memory and import a startling statistic 24 GB of VRAM. This configuration provides a 4096 bit memory bus with amazing bandwidth 2048 GB / s, indicating that AMD would be using batteries for 6 Hi or 12 Hi of HBM2e in 2 or 4 stack configurations die.
This point is less clear, because although the Hi Hi 12 batteries actually do exist, they are not without problems, as mentioned, there are capacitive and resistance limits as the capacity / height of each stack increases.
This is directly influenced by the high speed, since adding more layers prevents GB / s and thus GB rate of VRAM.

In addition, even if 12 Hi's had happened, AMD would still be taking the best SK Hynix modules, which would have an impact on the final card prices, so if it is true it is highly likely that the price will rise.
What seems clear is that when these definitions are confirmed we are talking about a large chip, with two symbols of a RX 5700 XT, triple L2 with VRAM and bandwidth 4 times higher.
Now we just need to know its official launch date and price. Place your bet …
