 Intel possède bien un 13900KS plus rapide  (...] : vendu plusieurs dizaines d’euros plus cher que le 7950X3D, il reste légèrement moins performant que ce dernier. "

But the Ryzen 9 7950X3D is not only very fast, but also very energy efficient. What the Ryzen 9 7950X still needed an average of 105 watts for in the test, the Ryzen 9 7950X3D only needs 72 watts - with better performance at the same time. The Core i9-13900K even has 141 watts, the KS model 147 watts. Here the new AMD processor delivers twice as many FPS per watt - that's impressive
