ARM and 28 nm process: the frequency of the nuclei to 2.8 GHz04.06.2019
The boom of mobile devices makes us increasingly turn to the topic of processors with ARM-architecture: first of all, because this year they will be actively used in tablet computers, where it is important not only low power consumption, but also developed functionality and performance. Intel is trying to compete with ARM-based processors using economical versions of processors with the x86-based architecture, the NVIDIA bets on Tegra processors with ARM-architecture and built-in graphics core, AMD while watching these from the process, trying to promote its x86-compatible architecture Bobcat .
ARM and Globalfoundries have already reported about the successes in the development of 28-nm process technology, but no technical details of the first report on this topic we did not indulge. The situation was corrected site PC Perspective, which published a slide from the presentation, showing some of the characteristics of the future 28 nm processors ARM.
As it turns out, in the dual-core configuration, these processors can operate at a nominal frequency of 2.5 GHz, and after a slight increase in the nominal voltage can dynamically overclock to 2.8 GHz. Apparently, we are talking about some kind of dynamic acceleration technology, similar to the know-how already using Intel and AMD. If we consider that produced on 40 nm technology ARM processors can only run at a frequency of 2.0 GHz, the progress is obvious. Of course, ARM each client itself will form the main characteristics of the processor, and not all serial products will operate at frequencies above 2.0 GHz.
