Eight cores with a tower of vertically-stacked L3 sitting directly on the die. Eight more cores without — for the workloads that prefer raw frequency over locality. The 7950X3D doesn't choose; it routes the work and lets each half do what it's best at. Frame-time variance collapses; benchmark charts go quiet.
“Cache so deep it changes the conversation.”
