Sapphire already changed the specifications page of its Radeon RX 5600 XT PULSE:
Sapphire RX 5600 XT Pulse was officially released with a 1560 MHz game clock and 1620 MHz boosts clock (you can still find the official press release here). The clocks, however, have been changed today on the website to 1615 MHz and 1750 MHz respectively. What is also interesting is that the memory clock is also changed to 14 Gbps.It's believed that this may be AMD's answer to NVIDIA's GeForce RTX 2060 price cut.
