And with such games, we mean titles that need to push extremely high framerates; the result is visible frame drops. A substantial number of RX 6000 graphics card owners seem to acknowledge the problem.

Over at AMD's Community support page, a thread is filled with reports on frame drops in games like Rocket League, Fortnite, and Counter-Strike: Global Offensive. CPU-intensive games like CS: GO, according to Redditor Tricolor3s, for example, would show abnormally large drops. His RX 6700 XT would perform less well than the Vega 56 (which he owned before) in such a situation. For example, CS: GO shows drops from 400 to 150 with the 6700 XT, Fortnite records a drop from 400 to 50 fps. The cards' clock speeds would go up and down sharply, which see looks to be the root cause. AMD is aware of the issue and is looking into this. Thus far, a precise cause has not been fed back, but a solution is being sought.
