In a previous article, we covered the apparent boost in specifications to the Radeon RX 5600XT lineup as a way to possibly counter the drop in the price of the RTX 2060. They would boost these specs by allowing for a BIOS update to the graphics cards for the manufacturers that would essentially overclock the GPU core frequencies as well as take the memory from 12Gbps up to the much faster 14Gbps resulting in an increased bandwidth to 336GB/s from 288GB/s, a welcome boost. The boost also comes at the expense of TDP by bumping the RX 5600XT cards from 150w to 160w, a modest lift for what should be more than worth it in performance but as always the reviews will reveal if that's the case or not.

PowerColor, in a press release shared by Videocardz, revealed that it was indeed a last-minute change on the heels of Sapphire. The caveat for this is it appears that some cards had already shipped out to retailers with the initial RX 5600XT BIOS loaded meaning that if end users want this performance-boosting BIOS they will need to load it themselves.
