"The best-case projection of performance
AMD’s benchmarks were unfortunately not very comprehensive, at least not for Ultra HD without ray tracing. To be on the safe side, I picked the best case of the games, but I warn against making absolute generalizations. So it’s unlikely to get better, though it will certainly get worse in some games. I beat the poor MSI GeForce RTX 3090 Ti SUPRIM X to almost 500 watts to at least get within the supposed proximity of the NDA-protected GeForce RTX 4080. Based on the extrapolation, we see about 11 percentage points advantage of the GeForce RTX 4090 FE to the Radeon RX 7900 XTX without extended power limit. I’ll come to the power consumption and possible efficiency in the next chapter.

The calculated bars also show that the Radeon RX 7900 XTX should be a bit faster than a GeForce GTX 4080 FE 16GB, if all positive factors and the lack of ray tracing coincide, while the Radeon RX 7900XT, which I had already positioned weeks ago, ends up exactly where I had already estimated it back then (and was also criticized from relevant circles for it): namely below the GeForce RTX 4080 16GB and probably a bit above a still expected GeForce RTX 4070, which is actually the discontinued RTX 4080 12GB.

Tis is exactly the deep-green sandwich I predicted when there was no talk of the XTX. The Radeon RX 4080 16GB and the Radeon RX 7900XTX shouldn’t have anything to do with ray tracing, and depending on the game, Team Red or Team Green should be ahead. The Radeon RX 7900XTX probably inherits, despite decent improvement, the slight weakness in almost all DXR game types."

A parte il DXR dove pare a tutti evidente che non sarà al livello della 4080, ma della 4070 si, lui la sottostima parecchio, cioè dice che nel caso migliore sarà al pari della 4080...

Evidentemente non ha visto la stessa presentazione Nvidia dove dichiarano -25% dalla 4090 e i leak di ieri sui sintetici.

Anyway...

Beh, hanno già fatto dei calcoli approssimativi e la 7900 XTX andrà più di una 4080 e meno di 4090 (con la differenza di costare 600 euro in meno di listino), pur mantenendo prestazioni RT da 3090TI (che non mi pare fosse da gettare nel cassonetto).

Non male per una dual slot a 350W.
