Integrated graphics are also very power efficient, since they use very little power beyond what the CPU was already using in the first place.
And, thanks to their standardization, you’ll rarely run into any issues with drivers or compatibility.
You with dozens of mods and add-ons while still enjoying butter smooth travel through the fantasy realm? Want to buy any top-tier title that comes out this year and enjoy stutter-free playback on your new 4K monitor? Graphics cards are useful for some non-gamers, too.
If you do a lot of photo editing (not just cropping and fixing the white balance type stuff, but intense Photoshop work), video editing, or any kind of rendering (3D art, design, etc.), then you’ll certainly get a boost from a dedicated GPU.
You don’t even need a GPU for playing older games, as today’s integrated graphics are far better than the dedicated video cards of decades past.
This means any graphics-heavy task you throw at the integrated system, like rendering video, playing a current generation 3D video game, or the like, will consume a hefty chunk of your system resources and there might not be enough to go around.
On the opposite side of the GPU spectrum, in terms of both price and performance, you’ll find dedicated GPUs.
Throw a modern game at an integrated GPU and it might stutter through it or, worse, just outright fail to load the game.
In addition, an integrated GPU shares all the resources the CPU shares, including your pool of RAM.
