Playing games with a dedicated graphics card is almost always going to be a better experience than playing with an onboard GPU. Why would you play games without a graphics card? Most onboard graphics have to make use of the general system memory, which is both slower and shared with the CPU, so there’s less of it, at a higher latency, with reduced bandwidth compared to the faster-dedicated RAM on most graphics cards. Graphics cards also have their own video memory, and lots of it, giving them much more memory bandwidth to work with. The reason for that is due to dedicated graphics cards being bigger, and having more space for larger dies with more cores and larger coolers, enabling higher clock speeds and power draw. Where integrated graphics may be starting to compete directly with entry-level graphics cards from 5-6 years ago, it will be many years until they can compete with high-end cards from that time, and more still, until they can compare to the best GPUs of 2022. The same is true of dedicated graphics cards, however.
Recent-generation onboard graphics feature greater core counts, more advanced architectures, and higher clock speeds, and are often made on smaller process technologies, enabling greater efficiency alongside the increased graphical performance. That means that modern-day CPUs featuring the latest generations of onboard graphics have become rather capable. However, that doesn’t mean they can’t play at all, and as dedicated graphics card technology has advanced, so too have onboard GPUs. But, the kind of onboard graphics that run entry-level laptops are not designed to handle the complexity and demands of modern 3D games.
Every computer, whether it’s a laptop or desktop PC, needs some form of graphics card or integrated GPU to run a display.
