AMD’s new APUs follow the company’s seventh-generation “Bristol Ridge” chips released in the middle of 2016. The new APUs promise up to 200 percent more CPU performance than the Bristol Ridge generation, up to 128 percent more graphics performance, and up to 58 percent less power consumption. The Ryzen cores are based on AMD’s new “Zen” CPU core design that was built from scratch to generate higher performance on a lower power draw, and a lower price tag.
If you’re looking for gaming on the go, laptops with these two new APUs can provide decent framerates without a secondary discrete GPU. AMD says the Vega cores can generate an average rate of 43 frames per second in Quake Champions using a 1,280 x 720 resolution and high graphics settings. The chips can also manage an average of 66 frames per second in Overwatch (1,280 x 720 / low), and 59 frames per second in League of Legends (1,920 x 1,080 / medium).
The two new APUs include AMD’s new SenseMi technology suite that adjusts the APU’s power consumption per workload so it’s not constantly draining your battery. This suite also includes an updated, second-generation Precision Boost component that will adjust the clock speed when needed in 25MHz increments using a new algorithm. This component provides the highest possible speed to achieve the maximum performance in games and other heavy workloads.
According to AMD, the new APUs are capable of boosting their performance beyond their out-of-the-box boost speed with the proper cooling system installed (aka Mobile XFR). That means you may see “overclocked” chips served up in certain laptops. Artificial intelligence is baked into each Ryzen core for mapping power and consumption for better application behavior.
Finally, in the 3DMark Time Spy benchmark, AMD shows that its Ryzen 7 2700U APU outperforms the GeForce GTX 950M discrete graphics chip and Intel’s Core i7-7500U processor for laptops. Ultimately, the bottom line is that AMD is targeting desktop performance for ultra-thin
