Right, 3D cache and higher base frequency make a difference between 120W TDP vs 65W TDP, both CPUs are 8c/16t means also higher power consumption in idle. I tested R5 9600X recently in Cinebench 2024, and R5 9600X and R7 9700X have world-class performance per core (/single core), especially if we count 65W TDP. Therefore, they are beating the older AMD as well as the Intel CPU easily.
Look at this topic, I made the comparison with my friends’ CPUs as well. First AM5 R5 9600X CPU impressions
