i.mx6Q outperforming i.mx6QP in 3D

I'm running a 3D rendering test with the following setup:


OS: Yocto 4.1.15_1.1.0-GA

Platforms: i.mx6Q (SabreSD), i.mx6QP (auto, running stand alone)

1080p HDMI display


I load a 20,605 triangle model and get the following results:

When using a FBO with a 1080p resultion:

Q - ~17

QP - ~44

(everything as expected)


with NO FBO and 1080p:

Q - ~46

QP - ~44

(wait, what?)


Now here it gets weird: NO FBO, but using a glViewport of 800x480

Q - ~91

QP- ~44

(wait a minute...)


What is going on? Is there ANY case where the Quad would outperform the QP?

I'm running the exact same binaries and assets in both platforms, I can provide binaries, source, and assets if required.
