There is no fixed standard, but there is a general parameter: the half-height graphics card height is about 8CM, and the full-height graphics card height is about 12CM. The value of different graphics cards will change to some extent, but the difference is not great.

Half-height graphics card is also called knife card, which is also the common name of small-size graphics card suitable for mini-host users with limited space.

Although the types of knife cards are reduced, it is not a simplified version of the product, and it is not much different from the full-size board graphics card in function and performance. This kind of graphics card is generally only produced by manufacturers and OEM customers with equivalent R&D strength.
