How did we pick the best CPU for deep learning?
When it comes to selecting the best CPU, there are several key factors to consider. First and foremost, the CPU’s core count and clock speed are critical in ensuring the fast and efficient processing of data.
Deep learning involves working with massive datasets and having a high core count and clock speed can significantly reduce the time it takes to train models. Additionally, a large cache and high memory bandwidth are essential for minimizing data retrieval time and enabling fast data transfer between the CPU and memory.
Another critical consideration when selecting a CPU is its compatibility with popular deep-learning libraries such as TensorFlow, PyTorch, and Keras. These libraries are widely used in the data science community, and having a CPU that can effectively support them can streamline the development process.
What’s more, the CPU’s ability to support the complexity of vectorization is crucial in ensuring the efficient processing of large datasets. Low-latency interconnects are also vital for enabling efficient communication with other hardware components in the system, such as GPUs or RAM.
While weighing in on the specs and heavy details, matters such as budget and affordability never left our minds either. There’s a whole world to dive into with professional CPUs such as the AMD Threadripper Pro series, but this time around, we just wanted to provide consumer-focused picks.
We also made sure to lean heavily on our hands-on experience and cherry-picked the perfect lineup that we’ve approved in our in-house reviews from the PC Guide testing lab.

Features and considerations
The first thing to consider is how demanding a PC you’ll be looking to build. For demanding professional workloads, it is advisable to opt for AMD Threadripper or Intel Xeon W CPUs. These CPUs are preferred because they offer more lanes to accommodate multiple GPUs, making them the ideal choice for serious professional workloads.
If those are not the cases and you don’t need a CPU with multiple GPU lanes, then you’ll need to choose a strong GPU with a high core count to enable parallel processing of large amounts of data. The high CPU cores are the more crucial aspect to consider. Once that’s taken care of, you’ll need a high-frequency CPU so the unit can perform multiple calculations fast.
So far, these are the usual requirements for a high-end CPU. To be a bit more specific about what you’ll be looking for, consider low-latency interconnects. The CPU should enable efficient communication with other system components, such as graphics cards or memory.
Moreover, the CPU should support popular deep learning libraries such as TensorFlow, PyTorch, and Keras that have a focus on artificial and deep neural networks.
To complete your PC setup, consider investing in a GPU with NVIDIA tensor cores. Tensor cores are specifically designed to perform matrix operations, which are a key part of deep learning algorithms.

Do I need a good CPU for deep learning?
Yes, you definitely need a good CPU for deep learning. These AI models are computationally intensive and require a lot of processing power to train and run. Ensuring you invest in a high-quality CPU will help speed up the training process and improve your models’ performance.
Should I get an AMD or Intel CPU for deep learning?
Obviously, user preference has a huge role in answering this question, and it will differ from person to person. However, while Intel chips can beast-mode some deep learning tasks and have a wide variety of RAM, often getting this performance means that they will guzzle through your power and be quite demanding.
On the other hand, AMD processors might be a bit more particular with their RAM usage, but you might find they have the capability to perform really highly with very little power consumption.
