The GPU core config of the Wii U is 320:16:8 (SP:TMU:ROP)... that's account per 352 GFLOPS in raw power at 550Mhz.
You can have others units to help and free up these 352 GFLOPS but the raw power of the GPU is fixed... so you can have a fixed unit to do some job that free up this task from the GPU so no power of the GPU is used in this task... all the raw power is used to others tasks.
A fixed unit, "special sauce", what a hell you named it don't addeed FLOPS to overall raw power of the GPU... they just free up this power.
That's what I understand.
