The new Zen3 cores from the upcoming Ryzen 5000 mobile APUs seem to be more proficient at single-core tasks, as the Ryzen 7 5800U shows 20% higher single-core scores compared to the Ryzen 7 5700U model that integrates Zen2 cores. However, the Zen3 cores do not offer any significant benefits in multi-core tests, with only 2.6% performance uplift.

No Thunderbolt=No AMD. When will they take it seriously? I need it for 10 GbE networking.
Let's hope it's available, unlike 4800U which is mysteriously only in China.
This is strange. If single-core performance is improved, that should automatically translate to multi-core performance, i.e. if each core is 20% faster, logically it would follow that the whole CPU with all cores working would be 20% faster as well. Otherwise, it means it can't maintain that increase with all cores running, which hints at the improvements being due to clock speed vs IPC. IOW, these results seem to indicate the performance improvements are due not to improved architecture, but rather higher clock speed, specifically higher boost speed.

I believe this should be available via USB 4, which should be on AMD systems next year.
