Programmable pixel blending method and apparatus, computer device, storage medium and computer program product are provided. The method includes: performing rasterization on a first triangle, a second triangle, and a third triangle via the raster unit to obtain triangle coverage information of each triangle; sending the triangle coverage information to the warp assembly unit and the warp reorder unit respectively; assembling, by the warp assembly unit, the first triangle and the second triangle into a first warp, and requesting a warp from a warp request interface based on information of the first warp; executing the first warp based on a warp information cache, a warp synchronization unit, the warp reorder unit, the pixel operation unit, the interpolation unit, and the execution unit; after the first warp is executed, continuing to assemble, by the warp assembly unit, the third triangle and completing a rendering of the third triangle.
