AMD announced today its first two processors to combine its new Zen CPU architecture with its Vega graphics. The new chips, aimed at lightweight mobile systems, go head to head with Intel's U-series processors, and for the first time in many years, AMD is going to have competitive chips in the thin-and-light laptop market.

AMD's Ryzen and Threadripper processors re-established AMD's chips as competitive with Intel's. While the AMD parts gave up a bit of performance to their Intel rivals, especially in single-threaded tasks—a result of the combination of slightly lower clock speeds and slightly inferior instructions-per-cycle (IPC)—they shine in multithreaded tasks, with AMD often offering many more cores and threads than Intel for the same or less money.
