The Radeon RX 6600 XT is a GPU that uses the RDNA 2 architecture and is a model that mainly targets full HD resolution. The frame rate of AAA titles is up to 1.7 times higher than the Radeon RX 5700 /... PowerColor prepares two types of Radeon RX 6600 XT Red Devil" and Hellhound
No way that RX 6600 XT would be up to 1.7x times faster than RX 5700 in 1080p in any game or benchmark with same graphics settings, maybe if 1.2x or 1.3x counts as "up to", dunno .
there always have been outlier games that outperform on either red or green. but i agree that a full 1.7 across the board is doubtful
6700xt is only ~1.20-1.30x the 5700xt. AMD's marketing is outstanding perspective of fake news and misinformation. 6600xt should be ~1.05-1.15x at best.
