What are they comparing when they say 60% multithreaded applications? Nova Lake with 16P + 32E +4LP-E has 62% more cores than Arrow Lakes 8P + 24E cores, so a 60% uplift is rather poor. Even if we ignore the LP-E cores, Nova has a 50% uplift in cores so a 60% uplift in multithreading is still very weak given the massive architectural changes, improved cores, IPC and clock uplifts. I suspect Nova Ultra 9 will do better than 60% compared to Arrow Ultra 9.
As for gaming leadership LOL, Zen 6 gets 12 core ccd's, 10-15% IPC uplifts, 7GHz clocks, faster IF, faster memory support, 10800X3D with 12 cores and at least 6GHz boost clocks will be insane and Zen 7 is even more crazy.
