Coming back to its clock speeds, the "Extreme Edition" appears to be a 100 MHz speed bump over the Ryzen 7 4800U, a 15-Watt part with 4.20 GHz max boost. The 45-Watt Ryzen 7 4800H has the same 4.20 GHz boost clock, but much higher 2.90 GHz nominal clocks. It hence stands to reason that this is a 15 W segment part, topping the 4800U, targeting ultraportables. Interestingly, a 15-Watt Renoir with these clock speeds was recently reported as the "Ryzen 9 4900U." We'll hear more in the coming weeks.
