AMD has released two new Ryzen processors designed for high-end laptops with lots of room for more power, especially when it comes thermal capacity. These processors begin a new H Series line of parts for AMD, much similar to Intel's own H Series of mobile chips.

These two new processors, known as the AMD Ryzen 5 2600H and Ryzen 7 2800H, are both still quad-core chips with base clock speeds and thermal design power (TDP) brought way up in comparison to their U Series predecessors. (You'll also see a minor increase in GPU cores between 2700U and 2800H.)
