AI Hardware Showdown: CPU vs GPU vs NPU (2024)

FAQs

Is NPU better than GPU? ›

NPUs are specifically designed to accelerate the processing and training of neural networks, delivering superior performance over CPUs and GPUs.

Enterprises generally prefer GPUs because most AI applications require parallel processing of multiple calculations. Examples include: Neural networks.

So to answer the question, While NPUs are optimized for matrix operations and parallel processing, which are essential for deep learning, they are not a direct replacement for CPUs (Central Processing Units) and GPUs (Graphics Processing Units).

The specialised design of NPUs allows them to perform AI tasks with greater energy efficiency than CPUs. This is particularly important in large-scale AI applications, where the energy costs of training and running AI models can be substantial.

As the PC industry enters a transformative era, integrating NPUs as standard processing technology is not just a potential development but a vital one. This transition has the power to redefine the future of computing, underscoring the need for industry professionals to keep pace with these changes.

GPUs have more of a general-purpose architecture than NPUs and can struggle to compete with NPUs in processing large-scale language models or edge computing applications.

CPUs are optimized for sequential serial processing, which is ideal for a wide range of general-purpose computing tasks. However, they struggle with the highly parallel nature of graphics rendering and the massive computational requirements of AI.

In conclusion, AI models can run on both CPUs and GPUs, and the choice of which one to use depends on the specific task and the complexity of the AI model. CPUs are better suited for simpler tasks with smaller datasets, while GPUs excel at handling large datasets and complex deep learning models.

* Faster training times: GPUs can train models much faster than CPUs due to their parallel processing capabilities and high memory bandwidth.

Key Takeaways. NPUs are efficient for AI workloads, serving a different purpose than GPUs. NPU advantages include lower latency, specialized memory hierarchies, and reduced power consumption.

Will Windows 12 need a NPU? ›

Microsoft is projected to release a new version of its operating system, called Windows 12, near the end of 2024. The new operating system is expected to heavily emphasize AI capabilities through the use of a Neural Processing Unit (NPU).

While the hardware is undoubtedly advanced, the true “magic” of the Intel NPU is realized through a sophisticated MLIR based compiler. It is through compiler technology that Intel's NPU reaches its full potential by optimizing and orchestrating AI workloads.

It excels at AI tasks and frees your CPU and GPU up for other tasks. Combining an NPU with machine learning gives you a powerful combo. It provides lightning-fast, high-bandwidth AI in real time—a great advantage for using voice commands, creating images quickly, and more. It helps you work fast and be more creative.

Copilot+ PCs powered by Snapdragon X Elite deliver 45 NPU TOPS performance — the fastest available.

NPUs are specially designed to process machine learning algorithms. While GPUs are very good at processing parallel data, NPUs are purpose-built for the computations necessary to run neural networks responsible for AI/ML processes.

PowerColor's new tech uses the NPU to reduce gaming power usage — vendor-provided benchmarks show up to 22.4% lower power consumption.
