A Quick Breakdown Of AMD's New Ryzen Mobile Processors

He pointed to AMD's current benchmark de jour, Cinebench, which suggested that the 15-watt Ryzen 7 2700U could outpace Intel's Core i5-7600K desktop CPU by a significant margin. Compared to AMD's previous "Bristol Ridge" mobile APU offerings, the company is claiming up to 3X CPU performance, 2.3X graphics performance, and 58 percent less power consumption.
Although the chips haven't be tested by outside benchmarkers yet, AMD said that for thin laptop designs, its new mobile chips were 44% faster than competing chips at tasks using multiple CPU cores and 161% faster at graphics processing.
For its own part, AMD claims that the new Ryzen chips will offer dramatically improved performance over its own last generation of laptop chips, with up to 200 percent more CPU performance (for multicore use) and up to 128 percent better GPU performance, although AMD's last generation of chips weren't exactly computational powerhouses to start. These APUs will also feature Precision Boost 2, for accelerating performance depending on workload, and mobile Extended Frequency Range (mXFR) to raise performance when the cooling allows it.
The higher end Ryzen 7 2700U has a 2.2GHz base clock and 3.8GHz boost clock, along with 10 Radeon RX Vega compute units that can ramp up to 1,300MHz. It also has a lower GPU clock at 1100MHz instead of 1300MHz. Both APUs support DDR4-2400 memory. The Vega GPU cores chosen for both APUs are capable of providing playable performance for many popular titles. These CPUs will have low TDP and hence allow notebooks to have longer battery life.
Running on an HP Envy X360 with Ryzen 7 2700U and configured with 8 GB of RAM, less demanding games can easily remain over 30 FPS at 1080p.
In terms of efficiency, Ryzen Mobile has come in above expectations. Compared to just three years ago, Raven Ridge is almost six times more efficient than Kaveri which launched in 2014.
AMD says that systems powered by its Ryzen 7 and Ryzen 5 mobile processors will be available "in the coming weeks" from partners like Acer, HP, and Lenovo.
Jason Banta, director of product management, AMD Client Compute, made the claim earlier this week in a launch briefing of its Ryzen microprocessors intended for high-end ultra-books, and thin and light laptops.
