AMD’s New Mobile Ryzen CPUs Hit a Power Efficiency Milestone

Back in 2014, AMD (NASDAQ: AMD) said the power efficiency of its mobile chips would improve 25-fold by 2020. It recently blew past that "25x20" goal with its "Renoir" Ryzen 4800H mobile chipsets, which boast a 31.7x increase in power efficiency over its "Kaveri" chipsets from 2014.

AMD launched the Renoir chips earlier this year to succeed last year's "Picasso" chips. Renoir marks a big upgrade from Picasso, switching from Globalfoundries' 12nm process to TSMC's (NYSE: TSM) 7nm process and doubling its number of cores to eight. It's also integrated with a Vega GPU for high-end gaming.

The upgrade not only boosted Renoir's power efficiency by 2.92x over Picasso, it also improved its clock-for-clock performance by 15%-20%. It also offers better graphics performance and significantly more memory bandwidth at low power settings.
