With its new Ryzen 5000 laptop processors, code-named Cezanne, AMD strikes back against Intel's Tiger Lake, delivering better performance for ultrathin PCs. This generation's big upgrade is the Zen 3 CPU, which surpassed Intel's single-thread performance when it debuted last year in desktop products and appears poised to do the same in laptops. Despite a graphics-performance leap, Tiger Lake slightly trails the older Ryzen 4000 line for gaming on ultra-thin systems, and the new Ryzens should extend AMD's graphics lead. Boasting twice as many CPUs, AMD crushes Intel in multicore performance. AMD unveiled a full Cezanne lineup for laptops, including U-series parts at 15W TDP, HS-series parts at 35W, and H-series parts at 45W. Tiger Lake is available only at 15W and 28W, but Intel plans to introduce H-series versions later this quarter. The new Tiger Lake-H chips will match Cezanne with eight CPUs, and they also increase clock speeds to take advantage of the larger power envelope. Except for the low-cost Ryzen 5 models, the new AMD products all offer eight CPUs, and the high-end Ryzen 9-5980 has a maximum CPU speed of 4.8GHz.
