This is our first review of AMD's Ryzen Mobile 4000 U-series processors, the low power variants intended for slim, light, ultraportable laptops. Our exploration starts with the mid-range Ryzen 5 4500U, a 6 core, 6 thread part with 6 Vega GPU units. All with a default TDP of 15W.
The Ryzen 5 1600 (non-X) is virtually unchallenged in terms of value among enthusiasts processors. However, we've yet to determine the next best option for those who can't afford to spend $220 on AMD's six-core champion. For $170, the quad-core AMD Ryzen 5 1400 appears to be a great alternative.
As we begin to recover from the roller coaster ride that was Ryzen 7, we now have Ryzen 5 to address. AMD has announced four models in this series, including a pair of six-core CPUs as well as two quad-core models. We'll be pitting the sub-$200 1500X against the locked Core i5-7500 and the 1600X against the unlocked 7600K which compete in the $250 price range.
