The operating frequency turned out to be higher than expected. On average, when games are running at 4K, this comes in at 2450 MHz on our gaming panel. A frequency that also changes only slightly depending on the games.
Overall, the card behaves very well in 4K and allows you to play with a very satisfactory image rate in this definition. But again, the devil is in the details, because if the behavior of the card is really very interesting in games rendered in rasterization, the situation becomes more complicated when the effects in raytracing are active, and the situation worsens with an increasing number of RT effects.
In games with classic rendering (rasterization), the Radeon RX 7900 XT is 17% slower than the Radeon RX 7900 XTX. It is thus beaten by the GeForce RTX 4080 (+ 14%) and will especially have to face the GeForce RTX 4070 Ti, a model to come from Nvidia. Note, however, that this model is 15% faster than the GeForce RTX 3090, still in rasterization.
On the other hand, the RDNA 3 architecture does not completely eliminate the weak point of the previous generation of Radeon on raytracing rendering. AMD has indeed managed to achieve a rather interesting performance increase in this type of rendering, but it’s not enough to catch up with Nvidia. The RTX 4080 thus remains 42% faster in our panel of games and this lead tends to be outrageously higher as the effects in raytracing accumulate. In other words: on tomorrow’s games, it’s very likely that the Radeon RX 7900 XT will struggle even more.
