nonCortexA57

nonCortexA57 refers to processor cores that are not based on ARM's Cortex-A57 architecture. The Cortex-A57 is a high-performance ARMv8-A 64-bit processor core designed for demanding applications like smartphones, tablets, and servers. It was notable for its out-of-order execution capabilities and its role in early 64-bit ARM mobile SoCs.

Therefore, a "nonCortexA57" core could be any other processor core architecture. This includes a wide range of possibilities. It could be another ARM core, such as the Cortex-A53, Cortex-A72, Cortex-A76, or even custom ARM-based designs from companies like Apple (e.g., their "Hurricane" or "Monsoon" cores). It could also refer to cores from different Instruction Set Architectures (ISAs) altogether, such as x86 processors from Intel or AMD, or RISC-V cores.

The term is often used in contexts where a direct comparison is being made to the Cortex-A57, highlighting differences in performance, power efficiency, feature set, or target market. For instance, a newer ARM core might be described as a "nonCortexA57" successor, implying improvements over the older architecture. Similarly, in discussions about heterogeneous computing, a low-power "companion core" might be contrasted with a higher-performance "nonCortexA57" main core. Understanding what constitutes a "nonCortexA57" requires knowledge of the specific context in which the term is used, as it broadly encompasses all processor cores outside of that particular ARM design.
