I remember a demo and when I ran it on my A1200 it was slower than an early 80s PC-XT so lost interest.
Also AGA is so slow compared to EGA or even VGA byte per pixel that the CPU was the least of my problems anyway. And nobody did a decent replacement plug-in for A500/A1200 for chunky graphics and given the A4000 was so overpriced it was a real dead end for me personally. I gave up and bought a cheap PC for my Dbase 3 stuff etc for my Uni course.
