Just like with my review on SAPPHIRE's custom Radeon RX 5600 XT PULSE OC graphics card, I split the results of power and temperature numbers on MSI's custom Radeon RX 5600 XT GAMING X into two, too.
First up we have thermals, with MSI's new Radeon RX 5600 XT GAMING X coming in at 63C with its old BIOS and 68C with the new BIOS. On the old BIOS the GPU clocks sat at around 1570-1580MHz, with the fan speed at 39% or 1170RPM or so. But once things were changed over with the new BIOS the GPU clocks ramped to 1715-1730MHz, and the fan speed dropped to 25% and 800RPM. This can be adjusted without an issue with MSI Afterburner, though.
Power consumption was virtually identical to the SAPPHIRE Radeon RX 5600 XT PULSE OC, with MSI's new Radeon RX 5600 XT GAMING X using 185W with its old BIOS in my Core i7-8700K rig, while the new BIOS saw power numbers go up to 200W for the entire rig.
