AMD launches Ryzen mobile APUs equipped with Vega graphics


Several of AMD's hardware partners are getting ready to launch laptops powered by these new mobile processors, including Acer, HP, and Lenovo. There are two initial chips in the processor family that AMD is announcing today: the Ryzen 5 2500U and the Ryzen 7 2700U. Targeting ultrathin and 2-in-1 devices, the AMD Ryzen 7 2700U and Ryzen 5 2500U combine Zen with Vega graphics into an SoC for greatly improved performance. The difference is Intel's processors use a "refreshed" version of the seventh-generation Kaby Lake architecture and a rebranded version of the graphics processor that gains most of its improvements through the addition of a couple of cores and some tweaks.

Both processors are 15W chips and offer four cores and eight threads.

In summary, with Ryzen Mobile, AMD is offering 3X the CPU performance and up to 2.3X the GPU performance compared to last generation APUs, all while consuming 58 percent less power. One major difference is that Turbo Boost concentrates on a single fastest core for the boost, while Precision Boost treats all cores as equal; that's what accounts for the single vs. multicore performance differential between Intel and AMD. The Ryzen 5 model has a maximum clock speed of 3.6GHz and 8 GPU compute units running at 1100MHz. AMD also compared the Ryzen 7 2700U against the competition, with some of the results shown in the video below (along with the system configurations at the end), and claim up to 44% better multi-threaded CPU performance and up to 161% more graphics power. When it comes to graphics performance, AMD claims that its Ryzen 7 2700U APU alone outperforms an Intel Core i7-7500U with an Nvidia GeForce 950M GPU by 915 points to 900 in 3DMark Time Spy.

But now AMD is setting its sights even higher, toward laptops - arguably the most important segment of the computer category, and one where Intel's lines of Core i3, i5, and i7 chips have long reigned virtually uncontested by AMD. Dual-channel DDR4-2400 RAM is supported. A wider range of Ryzen-based APUs will be available in the new year, said Banta.

According to AMD, Mobile Ryzen is the evolution of the APU started back in 2011 with Llano. It allows CPU cores to adjust their speeds dynamically in small increments depending on the current workload as well as speed and power conditions.
