CES 2021: AMD Announces Ryzen 5000 Mobile Processors 2

The Ryzen 5900HX is an 8c/16t part with boost clocks up to 4.6 GHz, 20 MB L2+L3 cache, and a “45W+ TDP”. The faster Ryzen 9 5980HX takes max boost clocks up to 4.8 GHz with the same cache/TDP. The 45W+ TDP seems to indicates max performance requires 54W, based on the previous Ryzen 9 4900H’s 35-54W configurable TDP.

While this might not be the generation for improvements in overall power consumption at max clocks, the Zen 3 architecture as well as higher clocks (the previous-gen Ryzen 9 4900H topped out at 4.4 GHz) will bring faster single-threaded performance, even if multithreaded perf appears to offer modest gains over Ryzen 4000 based on this graph:
