AMD is going to release Radeon Polaris 30 (RX590, RX680) on 12-nm process technology

While Nvidia already sells the top models of the new generation of graphics cards RTX2080, AMD starts releasing, as before, cards for mass segment. And judging by the number of leaks about the new GPU chips Polaris 30, AMD will introduce the Radeon RX580 receiver in the near future.
It is unknown what name will have the new cards from AMD. According to one source, the company will stick to the same strategy and name of the graphics card RX670 and RX680 and others will be released only one version called the RX590. We will not focus on the names and move on to the technical specifications.

One of these sources can be found at this link.

If you believe the information reflected in the media, then video card RX590 (RX680) will be an updated version with more advanced process technology, as it was with generations RX480-RX580.
The main difference between Polaris 30 from its predecessor is the use of 12-nm process technology is 14 nm in the RX580. The number of stream processors remains the same (2304 pieces), but the GPU frequency will increase significantly from 1340 MHz to 1545 MHz (+ 15%). Memory metrics will remain at Polaris 20, that is to be installed GDDR5 memory with a frequency of 2000 MHz.
In synthetic 3DMark anticipated new has 4759 points (+ 8%), and RX580 – 4399.


The lag in tests RX580 is quite natural, given that many tasks dependent on memory performance.
Thus, it can be expected that mining video card Polaris 30 on the base will behave similarly, that is, the extraction of Ethereum, which is very memory-intensive, we are unlikely to see a significant increase in Hasrat and, most likely, the gap with the previous generation will not exceed 1-2 MH/s. For other algorithms that are less memory intensive and more dependent on the GPU, for example, Cryptonight or X16R, the performance gains RX680 will be approximately 15% from current readings Radeon RX580.

Projected Hasrat AMD on the basis of Polaris 30:

Power consumption will be about the same as the Radeon RX580, since the increase in the frequency of the GPU by 15% in direct proportion to the reduction process at the same 15%.
