Abstract
Recent research on vision backbone architectures has predominantly focused on optimizing efficiency for hardware platforms with high parallel processing capabilities. This category increasingly includes embedded systems such as mobile phones and embedded AI accelerator modules. In contrast, CPUs do not have the possibility to parallelize operations in the same manner, wherefore models benefit from a specific design philosophy that balances amount of operations (MACs) and hardware-efficient execution by having high MACs per second (MACpS). In pursuit of this, we investigate two modifications to standard convolutions, aimed at reducing computational cost: grouping convolutions and reducing kernel sizes. While both adaptations substantially decrease the total number of MACs required for inference, sustaining low latency necessitates preserving hardware-efficiency. Our experiments across diverse CPU devices confirm that these adaptations successfully retain high hardware-efficiency on CPUs. Based on these insights, we introduce CPUBone, a new family of vision backbone models optimized for CPU-based inference. CPUBone achieves state-of-the-art Speed-Accuracy Trade-offs (SATs) across a wide range of CPU devices and effectively transfers its efficiency to downstream tasks such as object detection and semantic segmentation. Models and code are available at https://github.com/altair199797/CPUBone.

WHY NOW
Efficient Vision Backbones for Edge Devices moved forward this cycle; last verified April 2026. Public score 7.0/10. Implementation evidence is present through a linked repository.
Based on these insights, we introduce CPUBone, a new family of vision backbone models optimized for CPU-based inference.
The abstract explicitly introduces CPUBone as a new family of models designed for CPU inference.

In pursuit of this, we investigate two modifications to standard convolutions, aimed at reducing computational cost: grouping convolutions and reducing kernel sizes.
The abstract and analysis section clearly state these two modifications as the core strategies for reducing computational cost.
partial
The GrMBConv has 23% less MACs than the MBConv block, averaged over the five channel dimensions featured in Table 1.
This is a specific quantitative result directly stated in the text, comparing two architectural variants.
partial
The GrFuMBConv block has 45% less MACs than the FuMBConv, independent of the channel dimension.
This is a specific quantitative result directly stated in the text, comparing two architectural variants.

CPUBone achieves state-of-the-art Speed-Accuracy Trade-offs (SATs) across a wide range of CPU devices and effectively transfers its efficiency to downstream tasks such as object detection and semantic segmentation.
This is a key performance claim made in the abstract, indicating superior performance compared to existing methods.
partial
CPUs offer limited parallelism, wherefore existing models optimized for devices with high parallelization capabilities [2, 27, 28] often fail to translate their efficiency to CPU-based systems [20].
This is a fundamental premise of the paper, explaining the motivation for CPUBone, and is stated multiple times.

In contrast, CPUs do not have the possibility to parallelize operations in the same manner, wherefore models benefit from a specific design philosophy that balances amount of operations (MACs) and hardware-efficient execution by having high MACs per second (MACpS).
This is a core problem statement that motivates the research and is clearly articulated in the abstract and introduction.
