The RX 7800 XT is a pretty good graphics card, but the performance improvement compared to the previous generation of RX 6800 XT, at least under Windows.
Phoronix recently tested under Linux, only to find out unexpectedlyOn the contrary, the performance of RX 7800 XT is not as good as that of the previous generation, and when running games, it lags behind RX 6800 XT by an average of as much as 11%, which is only equivalent to RX 6800.
In terms of specifications, the number of cores of the RX 7800 XT is actually 12 fewer sets of CU than the RX 6800 XT, but with the new RDNA3 architecture design, floating-point performance is much better than 80%.
However, this performance is theoretical, to the actual game has not been enough release, coupled with the Linux may not be optimized in place, there is such an embarrassing situation.
Of course,AMD graphics cards are good under Linux as a whole, and RX 6700 XT can stay slightly ahead of RTX 3080.
Intel Arc graphics cards are very bad, and the most high-end A770 is nearly 16% lower than the RTX 4060.
