The Ryzen 9 7950X is even faster in multi-core applications with a maximum of 88 watts than the Ryzen 9 5950X with 142 watts and with 65 watts even faster than the Core i9-12900K with 241 watts.
With 45 watts, the Ryzen 7 7700X clearly beats the Ryzen 9 6900HS for notebooks, which is trimmed for efficiency and also has 45 watts. This gives hope for extremely efficient, extremely fast Ryzen 7000 Mobile.

In multi-core loads, the 16-zen quad-core processor speeds up and away. Intel's CPUs don't stand a chance, even the Ryzen Threadripper 3970X with 32 Zen 3 cores is just missed

Grace à la fréquence nettement plus élevée, le gap est très intéressant, (clock to clock c'est +12% en multicpu)
