The APA102 led strip uses generic 2-wire SPI (one clock pin and one data pin), so you can push data much faster than with the WS2812B 800 KHz protocol and there's no specific timing required. They also have much higher PWM refresh rates, and less flickering.

This is the 30LED/m APA102 RGB strip! We also have APA102 RGB strips of 144 LED/m and 60 LED/m.
