There are those who say that generative artificial intelligence is as important a step for technology as the PC and the internet. With the world of technology taking a sharp turn towards AI, it was expected that the hardware in our smartphones and computers would begin to follow this trend. And this is already happening, with cutting-edge PCs and cell phones equipped with chips capable of optimizing this type of processing.

An AI PC has not only the CPU (central processing unit) and GPU (graphics processing unit) but also an NPU or neural processing unit. It is an optimized accelerator to perform AI and machine learning tasks directly on the computer

Currently, most of this processing takes place in data centers located outside Brazil, transferring data via the cloud, since current devices are not yet prepared for this type of task.

Greater efficiency and new features

With NPUs, PCs will be able to perform AI tasks more efficiently and with lower power consumption. This means that notebooks will be able to spend more time performing tasks until the next battery charge, for example.

An AI-ready PC promises to transform the way we use our computers every day. Imagine personal assistants that understand your needs, software that organizes your digital life, and tools that automatically enhance your photos and videos. All of this is made possible by local AI, which uses your own data to personalize and improve your experience.

More than just allowing the use of a ChatGPT, Gemini or Copilot Without the internet, PCs with AI will have more and more software and resources dedicated to making use of this type of processor, as is already happening with Adobe programs and video conferencing applications, such as Zoom.

Microsoft was one of those that announced its line of PCs with AI recently, on May 20th, called Copilot+ PC. The notebooks, which will have an integrated neural processor, will run new tools, such as Recall, which uses AI to create a searchable “photographic memory” of everything that was done, seen or said on the PC.

Capable of recording everything the user does, Recall allows you to recover past information, creating a detailed history of use of websites, applications, documents, meetings, exchanged messages and others, organizing this record in a timeline. The user is able to visually navigate the activities, presented through screenshots, and search for specific information.

More than 40 AI models will run as part of Windows 11 to power these new features. Microsoft’s built-in AI assistant Copilot will also receive support for OpenAI’s recently released GPT-4o model.

Is it now possible to buy a PC with AI?

The first Copilot+ PCs will be launched with Qualcomm processors on June 18th, at starting prices of US$999 (around R$5,100, in direct conversion). Models with Intel and AMD processors will arrive at a later date. Dell has also announced AI PCs with Qualcomm’s Snapdragon processors, such as new XPS models.

Although the prices of an IA PC are still high at first (an XPS 16, from Dell, can cost R$31,999), the tendency is that, as they are widely introduced into the market, they will become more accessible.

Dell Chief Operating Officer Jeff Clarke believes that 2 billion AI-enabled PCs will have been sold worldwide by 2030. Next year alone, Microsoft expects to sell 50 million laptops from its Copilot+ PC line.

Companies also believe that computers without NPU will become obsolete within a few years. Therefore, if you intend to buy a new PC in the next few years, whether notebook or desktop, be sure to consider those that are prepared for the new wave of AI.
