Mockingbird Posted October 26, 2017 Share Posted October 26, 2017 AMD announced that its Ryzen Mobile processors, the APUs formerly known as Raven Ridge, will be available in laptops from leading OEMs in time for the holiday season. The processors feature Zen compute cores paired with Radeon "Vega" graphics cores in an SoC (System on a Chip) design. AMD's Zen microarchitecture has truly had a transformative impact on the desktop PC industry. The bedrock Zen design, paired with the Infinity Fabric interconnect, provided enough performance for AMD to rise back into contention with Intel. This year alone, AMD has released a string of Zen-based Ryzen desktop products to satisfy nearly every pricing niche. Now it's time for AMD to tackle the mobile market. AMD has a key advantage over its rival Intel, though--it's the only company that produces both x86 processors and GPUs. The company unveiled its new Radeon RX Vega graphics cards earlier this year, and now the company is tying the graphics cores and Zen microarchitecture together with the Infinity Fabric. According to AMD, the pairing provides explosive performance gains of 44% more multi-threaded CPU performance and 161% more graphics performance than Intel's new Kaby Lake Refresh mobile processors. The Ryzen Mobile Die The Ryzen mobile processors debut with two SKUs. The "U" suffix denotes that the Ryzen 7 2700U and 2500U are destined for ultralights, but processors optimized for different devices will come to market over the next year. AMD hasn't said when the Zen+Vega PIB (Product In Box) APUs, which you'll be able to buy at retail, will arrive. Both Ryzen APUs feature four cores and eight threads, but in a big departure from the previous Ryzen models, they only feature a single Core Complex (CCX). Moving to a single CCX instead of the dual-CCX design currently found in the Ryzen desktop processors is a critical step. The design ensures that the Ryzen Mobile processors can slip in under the size, power, and thermal constraints of mobile products. We can spot the four-core CCX to the left of the die shot above. The Vega graphics cores populate the right side of the die. Speeds And Feeds Both 15W Ryzen Mobile processors feature four Zen cores and eight threads fed by 4MB of L3 cache. The design employs the same 14nm Global Foundries FinFET process as the Ryzen desktop models. The processors feature a dual-channel memory controller that supports up to DDR4-2400, but it is noteworthy that some OEM designs will only feature a single memory channel. That can reduce graphics performance significantly. The Ryzen 7 2700U slots in as the high-performance model with a 2.2GHz base and 3.8GHz Precision Boost frequency. The slightly lesser Ryzen 5 2500U model comes with a 2.0GHz base and 3.6GHz boost.

Yogurth Posted October 26, 2017 Share Posted October 26, 2017 (edited) According to AMD's internal presentation benchmarks, these are ~10% slower in single threaded tasks than Intel's counterparts but simply kill them in multithreading. I haven't found anything on how the Vega compares to Iris though. Seems like a great mobile chip. Strike that about GPU. Vega is fast! Link to comment Share on other sites More sharing options...
Emn1ty Posted October 26, 2017 Share Posted October 26, 2017 If this ships in a dell xps 13 and I can sell myself on windows Ubuntu... I'm definitely buying that configuration. Link to comment Share on other sites More sharing options...
