It looks like AMD will be changing the specifications of its upcoming Radeon RX 5600 XT graphics card through a BIOS update that is being pushed to manufacturers. According to a HKEPC report, AMD has increased the clock speeds of the card from 1375 MHz game and 1560 MHz boost to 1615 MHz gaming and 1750 MHz boost. Confirmation of this change comes from the product page of Sapphire’s RX 5600 XT Pulse graphics card, which does not have any “OC” mentioned. As you can see the clock speeds have been changed.
Besides just the GPU clocks, Sapphire has also increased the memory clock speeds from 12 Gbps to 14 Gbps (a 15% increase in memory bandwidth). With that the typical board power has gone up from 150W to 160W, which indicates a possible power-limit increase. These changes could make the RX 5600 XT more competitive against the RTX 2060, which has recevied a price-cut down to $299. We actually saw the EVGA GeForce RTX 2060 KO at CES, which is already selling for $299.99.
