Can you elaborate on that?Be aware, that the 3d hardware is still rather dated (even with the bumps for Pi4 and Pi5), and for general purpose compute,
you'll probably find the ARM on a Pi5 (with neon) has more performance.
If NEON can do 4 multiplies and accumulations per clock, it would be 2.4GHz*8 = 19.2 GFlops. With 4 cores this would be 76.8 GFlops.
To my knownledge the VideoCoreVII has 12 QPUs, each with 4 ALUs that can do two operations. This at 800Mhz gives 0.8 * 12 * 4 * 2 = 76.8 GFlops!
Is it that the practical Flops are for the CPUs more close to the theoretical Flops then for the GPU?
