How fast a processor you need depends on how you plan to use your PC. Most computers are overpowered for the average user, so unless you play a lot of CPU-intensive online games, you can probably get by with an affordable desktop PC or budget laptop.
Does More RAM Make Your PC Faster? (2020)
The processor (CPU) and RAM are the two most important components to look at when determining the speed of a computer. RAM is typically measured in gigabytes (GB) or terabytes (TB), while processing speed is measured in gigahertz (GHz).
The day-to-day tasks that most users perform are so minimally hardware-intensive that the low-end processors in newer computers are more than sufficient. For example, 2 to 4 GB of RAM and a 1.3 GHz Intel Core i3 processor should be fine for surfing the web, watching Blu-ray movies, and basic productivity tasks.
Most people use computers only for internet-related tasks, such as sending emails, surfing the web, checking social media networks, and streaming media content. While such tasks may be limited by the speed of your internet connection, they are not limited by processing power.
