Pine Technologies PT-521/3

The PT-521/3 arrived at a time when VGA performance depended as much on memory bandwidth as clock speed. Its Cirrus Logic GD5422 used a 32-bit memory interface, giving it a useful performance advantage over earlier low-cost ISA VGA cards while retaining excellent DOS compatibility. It was intended for users who wanted a responsive Super VGA card without paying for a Windows accelerator, making it a common choice for 386 and early 486 systems.
