How did we pick the best CPU for deep learning?

When it comes to selecting the best CPU for deep learning, 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 for deep learning 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 mind 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.

  • Performance comes with high power consumption, of 253W

The Intel Core i9-13900K is widely regarded as one of the best CPUs for deep learning. Its processing power is so impressive that it can even rival AMD Threadripper CPUs, making it unnecessary to opt for one of the Pro level products. One of the most significant advantages of the 13900K is its 20 PCIe express lanes, which can increase even further with a Z690/Z790 motherboard. This is crucial since many deep learning tasks rely on the GPU, and these extra lanes provide more power for GPU acceleration.

Additionally, this processor boasts an impressive hybrid architecture 24 cores, 32 threads, and 36MB of L3 cache. With the ability to boost up to 6GHz, this CPU delivers unparalleled performance for a consumer-grade processor. It’s important to note though, that this is a relatively expensive chip, and it also requires adequate cooling due to its power consumption of 253W. However, neither of these factors was enough to deter us from awarding it a commendable 4 stars in our i9-13900K review.

While the Intel Core i9-13900K is no longer the flagship it was at release, generous discounts and high performance still make it an ideal processor to consider in 2024.

  • An Intel Core i7-14700K processor on a white background.
  • A computer processor chip, specifically the Intel Core i7-14700K, centered on a plain white background with the word "guide" in the corner.
  • Intel Core i7-14700K
Reasons to Buy
  • Hybrid technology performs great
  • Leading for creativity, productivity, and data analysis
  • Its pricing is identical to previous generation
Reasons to Avoid
  • As a ‘refresh’, there’s not much of a leap from 13700K
  • Thread count could be higher considering the price
  • Technically, there are more affordable options available

For those a bit tighter for money or concerned about power consumption, the Intel Core i7-14700K is an excellent option for deep learning. Unlike other Intel CPUs, this chip delivers excellent performance and even outperforms Intel’s own 12th-Gen Core i9-12900K – the previous flagship.

Well, you might be confused about why we’ve donned the i7-14700K the title of ‘best CPU for deep learning for the money’. While there are cheaper options available, we don’t particularly recommend compromising on processing power by going for something like the Ryzen 5 7600X or the Core i5 13600K. These processors may save you money, but you’ll miss out on higher clock speeds and find yourself lacking in overall processing power. It’s priced competitively for its performance offering, but it’s fairly widely agreed that the 14th gen doesn’t improve a lot over the 13th gen overall.

The 14700K is a great middle-ground for those looking to game and work on the same PC. This CPU has a plethora of cores and threads at its disposal to chew through basically any workload you can throw at it.

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 due to their capability of offering 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 is 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 requirement 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 components in the system, 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 make your PC setup complete, also consider investing in a GPU that comes with NVIDIA tensor cores. This is because 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 they require a lot of processing power to train and run. Ensuring you invest in a high-quality CPU will help to speed up the training process and improve the performance of your models.

Should I get an AMD or Intel CPU for deep learning?

Obviously, user preference has a huge role in the answer to 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.
