Radeon RX 7900 XTX: The first benchmarks should be treated with caution


One ​​week before the Radeon RX 7900 XTX and Radeon RX 7900 XT go on sale, the first benchmark results for AMD's new flagship graphics card are circulating online. However, the meaningfulness is questionable – on the one hand because the benchmarks are far from reality and on the other hand because drivers should not be final yet.

The same Game like GeForce RTX 4080

When Nvidia's second Ada Lovelace graphics card, the GeForce RTX 4080 (test), was in the starting blocks about a month ago, it was the @BenchLeaks Twitter account that was able to come up with the first benchmark results. The same game can now be seen with the Radeon RX 7900 XTX and again it is the Geekbench V5, which is actually not particularly meaningful in terms of real performance in games. In this respect, the obligatory note follows in advance: Caution is advised when interpreting the values. Nothing has to be right and a lot can still change, especially since the two benchmark results paint a different picture.

In the case of the GeForce RTX 4080, the OpenCL score, the Vulkan score and the CUDA score were leaked at the time; with the Radeon RX 7900 XTX, the latter is now missing for obvious reasons: AMD's graphics cards do not master the CUDA API developed by Nvidia. In the OpenCL benchmark, however, the future Radeon top model paired with an AMD Ryzen 7700X (test) on an Asus ROG Crosshair X670E Extreme achieves a score of 228,647 points, while 179,579 points are achieved in the Vulkan benchmark.

Of course, the classification of older AMD graphics cards and especially the GeForce RTX 4080, which AMD has explicitly planned as an opponent, is of interest. VideoCardz has compiled some benchmark results in a table for this purpose. And it is already noticeable at first glance: The reported values ​​of the Radeon RX 7900 XTX do not necessarily match. On the one hand, the graphics card in the Vulkan test run is around 15 percent faster than the GeForce RTX 4080 – which is around 23 percent missing from the GeForce RTX 4090 (test) – on the other hand the AMD model is around 14 percent slower than the GeForce in the OpenCL benchmark RTX 4080.

Clarity will only be brought by extensive tests

And that in turn raises questions which cannot yet be answered. It should be noted that the maximum GPU clock of the Radeon RX 7900 XTX in the OpenCL test run was only 2269 MHz, while recent information on Asus TUF custom designs specifies the theoretical boost clock at around 2600 MHz. The Vulcan benchmark does not specify a GPU clock. It is also conceivable that the graphics driver used was not final. Ultimately, there will only be clarity when the Radeon RX 7900 XTX and Radeon RX 7900 XT are launched. ComputerBase will come up with the usual extensive tests and benchmarks in due course.
