2D software rasterizer tournament

This benchmark was done on a single Cortex-A74 aarch64 core at 2Ghz

built using clang18, cairo and qt6 from alpine edge, blend2d, AGG and ctx with static linking.

Last updated:August 2024

The data for the RGBA8 time-trial benchmark is a blend2d-bench dataset, the numbers in the tables below are milliseconds to render 1000 shapes in the specified fill style - The data also can be visualized in more detail Blend2D's performance comparison page by using the custom dataset functionality.

	🥇	🥈	🥉
Blend2D	179	33	4
ctx	37	171	8
Qt6		3	88	75	50
cairo		8	48	80	44
AGG		1	68	25	14

The medal summary provides the overall data from the dataset at a glance. In the following summary we group the tests by how ctx is performing.

Heats won by ctx:

ctx in second place

ctx in third place

ctx in fourth place

ctx in fifth place

ctx last

Pixel formats

This shows performance for doing color fills of circles without and with alpha==1.0. The native formats of ctx, BGRA8, GRAYA8 GRAYAF RGBAF and CMYKAF are performing well, for some others like RGB565 shortcuts have been added to increase performance.
