There was a time when AMD was losing the market to Intel, but things have changed now, and AMD is often the one on the winning side. The US-based chipmaker announced that it has achieved the goal of creating 25 times power-efficient mobile processors in 2020 as compared to its processors in 2014.
AMD claims that the Ryzen 7 4800H is 31.7x power efficient than the baseline metric it set in 2014, thus, exceeding the initial goal of improving energy savings by 25x. Furthermore, the company has managed to reduce the average computing time for a task by 80% and energy consumption by 84%, again in comparison to 2014.
For reference, the energy efficiency of a chip is known by analyzing the performance per watt of energy consumed. The benefits of a power-efficient chip include better battery life, improved performance, and also it reduces the environmental impact.
AMD says that it worked on silicon-level optimizations and real-time power management features to reach the ’25×20′ goal, the name it gave to the goal in 2014. It goes without saying that AMD processors have shown significant performance improvements within the same time period.
The turning point in AMD’s story was the Zen microarchitecture that the company built- from the ground up. The original Zen was based on a 14nm process and introduced advanced features like Simultaneous Multithreading (SMT) to AMD CPUs. The latest version, Zen 3, is expected to arrive later this year and will be based on 7nm+ process.
