AMD Ryzen 4000 Series
AMD revealed its first 7-nanometer Ryzen processors for laptops, promising a mix of “ultra high-performance” and “ultrathin portability” that will reach more than 100 laptop designs in 2020, beginning in the first quarter.
AMD CEO Lisa Su called the new Ryzen 4000 series “the best” processors for ultrathin laptops, packing up to eight cores, 16 threads and a 4.2 GHz boost frequency in as little as a 15-watt thermal envelope.
The processors are split between three types: the U-series for ultrathin consumer laptops, the H-series for gaming and creator laptops and the Pro series for ultrathin commercial laptops.
At the top of the stack of the U-series is the AMD Ryzen 4800U, which comes with eight cores, 16 threads, up to 4.2GHz in boost frequency, a 1.7 GHz base frequency and eight Radeon GPU cores, all within a 15-watt thermal envelope that is needed for ultrathin laptops.
Comparing AMD’s Ryzen 7 4800U to Intel’s 10th-generation Core i7-1065G7, AMD’s new U-series processor provides 4 percent better single-threaded performance, 90 percent better multi-threaded performance and 28 percent better graphics performance.
For the H-series, the top processor is the Ryzen 7 4800U, which comes with eight cores, 16 threads, up to 4.2 GHz in boost frequency and a 2.9GHz base frequency within a 45-watt envelope.
