Graphics and parallel work
Thousands of small cores.
A different shape
A processor has a few fast cores for varied work. A graphics card has thousands of simple ones doing the same operation across huge amounts of data at once.
- That suits pixels, physics, video encoding and training neural networks.
- Video memory limits the size of the model or scene that fits.
Integrated and discrete
Integrated graphics share system memory and are fine for everything except games and heavy rendering. A discrete card has its own memory and its own cooling problem.
