AMD adds new laptop processors to its Ryzen 4000 7nm series

18 March 2020 0

AMD has added new Ryzen 4000 Mobile Renoir processors for laptops to its portfolio. The new additions include - the Ryzen 9 4900H and the 4900HS. AMD’s Ryzen 4000 series also includes the Ryzen U-Series, designed for ultra-portable laptops, and other members of the Ryzen H-Series — the six-core Ryzen 5 4600H and the 8-core Ryzen 7 4800H.

AMD unveiled the Ryzen 4000 CPUs at the CES 2020 and these two are just the new additions to the family. The new processors are built on 7nm process technology and optimized high-performance Radeon graphics. The 7nm fabrication features 9.8 billion transistors and the package is 25x25x1.38m in size, which means it is power efficient. The H-series are for gaming and creator laptops and they come with discrete CPU with higher TDP.


Both the laptop processors are based on Zen2 architecture, a refined version designed specifically for laptops. All the new Renoir CPUs use 7nm Vega graphics that brings a 25% higher peak graphics clock and 77% higher memory bandwidth. Both the new AMD Ryzen processors have enhanced IO connectivity and they both feature up to 8 graphics units and 8 processing cores (16 threads). The 35W 4900HS offers an eight-core, 16-three design and 3.0GHz clock speeds that can boost up to 4.3GHz. And, the 45W 4900H has a 3.3Ghz base with a boost up to 4.4GHz.

The company touts that its new chips deliver superior performance to that of their Intel competitors. According to AMD's own testing, the 4900H outperformed Intel’s Core i9-9880H by 28% on Cinebench R20 (which leverages the CPU to render a complex image), 23% on video transcoding, 56% on image rendering, and 32% on audio encoding.

AMD claims 25% IPC gain over Ryzen 3000M, 2x higher power efficiency, and 5x faster state switching with the new Ryzen 4000 processors. AMD also claims the 4900HS, paired with an Nvidia RTX 2060 Max-Q GPU, can surpass 60 frames per second on a number of AAA titles. AMD announced that the 4900HS will appear in Asus’ 14-inch ROG Zephyrus G14.
