The new AMD Ryzen microprocessor with the Vega graphics, provide mobile advantages in areas of power, battery consumption, and price/performance.

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.

But things are looking like they’re going to be different in the mobile space. That’s because the two new chips, the Ryzen 7 2700U and Ryzen 5 2500U, show signs of being faster in both processor and graphics tasks than Intel’s latest comparable chips.  On the graphics side, the difference is even more pronounced; in the Time Spy subtest of 3DMark, AMD is claiming performance of more than double that of Kaby Lake-R, even edging slightly ahead of a previous generation Kaby Lake paired with a GeForce 950M discrete GPU.

In bringing Zen to the mobile space, AMD has made some changes to power management and clock speed handling. At a static Windows desktop, AMD says that the chips can be in this powered-down state 99 percent of the time. The multimedia hub can also be powered separately from the CPU and main GPU core, so scenarios such as showing hardware-accelerated streaming video can keep the processor in its “mostly powered down” state for longer.
