The integrated graphics card is a small square integrated on the motherboard with a heat dissipation aluminum sheet on it. Discrete graphics cards are manufactured separately. Boards with fans (only look at some pictures of discrete graphics cards) have different volumes and different contents.

High heat output

The discrete graphics card is more complicated than the integrated graphics card, which runs faster and generates more heat, so it needs a faster fan instead of relying on air convection to dissipate heat like the integrated one.

AMD graphics card

Integrated AMD graphics card, core frequency 200Mhz~700+Mhz, 10~40 integrated stream processor, memory frequency 500Mhz~ 1033Mhz. Independent AMD graphics card, core frequency 450~900+Mhz, 80~ 1000 integrated stream processor, independent memory. Memory frequency 1033~4000MHz, with high fever.

Nvidia graphics card

These two graphics cards are very similar, except that the N card has a shader instead of a stream processor. The equivalent number of shaders and stream processors is roughly 1:8, and one shader is equivalent to eight stream processors, so the number of shaders in N card is not as many as that in A card.

Intel integrated graphics card

Intel also produces several integrated graphics cards: corei3, corei5 (integrated graphics card with cpu), G3 1, G4 1 and G45.
