Company Nvidia recently reduced the cost of a card GeForce RTX 2060to compete more successfully with Radeon RX 5600 XT. AMD responded sent out their partners a new BIOS, which should be able to speed up the new card well.
According to sources, the firmware raises the frequencies of the GPU and memory. For example, a model Sapphire Pulse RX 5600 XT will receive frequencies of 1615-1750 MHz for the video core (originally it was 1620 MHz) and 14 GHz for memory (it was 12 GHz). In addition, it raises the TDP from 150 to 160 watts.
However, as it turned out, not all partners will update the BIOS. In addition to Sapphire, accelerated cards will release Msi, although not the fact that this will be true for all versions of the RX 5600 XT. But those manufacturers who overclocked the chips on their own are unlikely to install a new BIOS. Among those mentioned Powercolor and Asus.
Thus, a situation may arise in the market when the same model will actually differ only in firmware. Therefore, buyers will need to keep track of this. However, it is possible that companies will simply mark overclocked cards to distinguish them from ordinary ones.
