Well, unless using A702 makes 3D applications run slower than when using llvmpipe. > >> [1] https://docs.qualcomm.com/bundle/publicresource/87-61720-1_REV_A_QUALCOMM_ROBOTICS_RB1_PLATFORM__QUALCOMM_QRB2210__PRODUCT_BRIEF.pdf > >> Signed-off-by: Konrad Dybcio <konrad.dybcio@linaro.org> > > > > With the exception of the commit message: > > :( > > Konrad > > > > > Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> > > > >> --- > >> arch/arm64/boot/dts/qcom/qrb2210-rb1.dts | 8 ++++++++ > >> 1 file changed, 8 insertions(+) > > > >

I found > this wording extremely funny though GPU (Graphics Processing Unit) isn't accurate either since it can also run compute shaders do to non graphics processing, so 3D Accelerator isn't that different. A proper term would be Vectorized Mathematical Computing Complex or something similar.
