    The NVIDIA Titan RTX is another mid-range graphics card for deep learning and complex computations. This model’s 24 GB of VRAM is enough to work with most batch sizes. However, if you wish to train larger models, pair this card with the NVLink bridge to effectively have 48 GB of VRAM. This amount would be enough even for large transformer NLP models.

    Moreover, Titan RTX allows for full-rate mixed-precision training for models (i.e., FP 16 along with FP32 accumulation). As a result, this model performs approximately 15 to 20 percent faster in operations where Tensor Cores are utilized.

    One limitation of the NVIDIA Titan RTX is the twin fan design. This hampers more complex system configurations because it cannot be packed into a workstation without substantial modifications to the cooling mechanism, which is not recommended.

    Overall, Titan is an excellent, all-purpose GPU for just about any deep learning task. Compared to other general-purpose graphics cards, it is certainly expensive. That is why this model is not recommended for gamers. Nevertheless, extra VRAM and performance boost would likely be appreciated by researchers utilizing complex deep learning models. The price of the Titan RTX is meaningfully less than the V100 showcased above and would be a good choice if your budget does not allow for V100 to do deep learning, or your workload does not need more than the Titan RTX (see interesting benchmarks)

    Choosing the best graphics card for AI, machine learning, and deep learning

    AI, machine learning, and deep learning tasks process heaps of data. These tasks can be very demanding on your hardware. Below are the features to keep in mind before you dive into the deep learning GPUs market.

    As a simple rule of thumb, the greater the number of cores, the higher will be the performance of your system. The number of cores should also be taken into consideration, particularly if you are dealing with a large amount of data. NVIDIA has named its cores CUDA, while AMD calls their cores stream processors. Go for the highest number of processing cores your budget will allow.

    Processing Power
    The processing power depends on the number of cores inside the system multiplied by the clock speeds at which you are running the cores. The higher the speed and the higher the number of cores, the higher the processing power your GPU can compute data. This also determines how fast your system will perform a task.

    Video RAM, or VRAM, is a measurement of the amount of data your system can handle at once. Higher VRAM is vital for a deep learning graphics card, especially if employed to work with various Computer Vision models or perform any CV Kaggle competitions. VRAM is not as important for NLP or for working with other categorical data.

    Memory Bandwidth
    The Memory Bandwidth is the rate at which data is read or stored into the memory. In simple terms, it is the speed of the VRAM. Measured in GB/s, more Memory Bandwidth means that the card can draw more data in less time, which translates into faster operation.

    Scalability is another important factor to consider when you dive into the deep learning GPU market. But not all GPUs are scalable. That’s when interconnection comes in handy. Interconnection gives you the ability to utilize multiple GPUs. Therefore you can then use distributed training strategies for your applications. Fortunately, all the GPUs mentioned in this list are scalable. Note: Nvidia has removed the interconnection feature on all of its GPUs that came before RTX 2080.

    Licensing and Supporting Software
    Please consider licensing before investing in an expensive graphics card. Not all cards can be used for all applications. For instance, Nvidia has restricted the use of CUDA software along with consumer-grade GPUs in a data center. So, you have to transition to production-grade GPUs for your data center applications. As for supporting software, Nvidia GPUs are best supported when it comes to framework integration and learning libraries. Its CUDA toolkit contains GPU acceleration libraries, C & C++ compiler, optimization, and other debugging tools to help you get started right away.

    GPU temperature can be a significant bottleneck in performance, especially when you have an Nvidia RTX GPU. Modern GPUs increase their speed to a maximum while running an algorithm. But as soon as a certain temperature threshold is reached, the GPU decreases processing speed to protect against overheating.

    The blower fan design for air coolers pushes air outside the system while the non-blower fans suck air in. In architecture where multiple GPUs are placed next to each other, non-blower fans will heat up more. If you are using air cooling in a setup with 3 to 4 GPUs, avoid non-blower fans.

    Water cooling is another option. Though expensive, this method is much more silent and ensures that even the beefiest GPU setups remain cool throughout the operation.

    Final Thoughts

    For most users foraying into deep learning, the RTX 2080 Ti or the RTX 3080 will provide the greatest bang for your buck as a beginner. Their only major drawback is a limited VRAM size. Training with larger batch sizes allows models to train faster and much more accurately, saving a lot of the user’s time. This is only possible when you have Quadro GPUs or a TITAN RTX. Using half-precision (FP16) allows models to fit in the GPUs with insufficient VRAM size [2].

    For more advanced users, however, Tesla V100 is where you should invest. That is our top pick for the best graphics card for deep learning, Artificial intelligence, and machine. That is all for this article. We hope this article provided useful information for your next deep learning GPU. Each of the GPUs mentioned here has unique features, catering to different demographics and applications. You will definitely find your ideal GPU among them. Good luck!
