The speed and power of a processor (aka the 'brain' of your computer) determines how well and how fast your computer can do things like create spreadsheets, play games, browse the internet, run software, and more. The more cores a processor has, the better it will be at doing multiple things at once.

Copilot+ PCs: Copilot+ PCs have at least 16GB RAM, 256GB storage, and a NPU that runs 40+ TOPs with a Microsoft Copilot key to run Copilot+ that’s stored on your device.

AI PCs or AI Ready PCs:  Have a Microsoft Copilot key to run the Copilot assistant along with a NPU capable of 10+ TOPs.

AI-Ready Workstations: AI-Ready Workstations are available in Intel® HX, Xeon®, or AMD Ryzen™ Threadripper™ Pro CPUs with up to 4x NVIDIA RTX 6000 Ada Generation GPUs.

AI-Powered Gaming PCs: These systems feature Lenovo AI Engine+ and NVIDIA® GeForce RTX™ GPU's to handle AI-driven tasks and deliver exceptional gaming performance.

Memory or Random Access Memory (RAM) allows your computer to multitask. It temporarily stores data and the higher number of GB (Gigabytes) means more applications can be running in tandem without slowdowns. Some intensive applications for gaming or video editing, require more RAM for optimal performance.
Memory described as 'DDR' stands for 'Double Data Rate' and processes data approximately twice as fast as a standard memory module. When a number appears after DDR (ie DDR3) that type of memory is approximately twice as fast as the previous generation.

The hard drive is where a computer stores all files, pictures, music, and programs. Different from memory which is temporary when in use, storage determines how much data can be saved on the computer. Measured in  Gigabytes (GB) and Terabytes (TB). Terabytes are 1,000 gigabytes.
There are HDD (hard disk) and SSD (solid state) drives. SSDs are faster and use less energy, while HDDs have the ability to store more data and are typically larger in size.

The graphics card (or video card or GPU) displays everything you see and are an essential piece of hardware. It determines the range of color, how sharp images appear, and how well videos or games run without stuttering or pausing. Integrated graphics are built-in to your PC's processor, while dedicated or discrete graphics are separate from the processor and enable you to run smoothly more advanced programs although they typically use more power.
