Um, I think you have things backwards here. By this time, the Amiga was technologically ancient. I know because I upgraded my old Amiga 500 to a sparkling "new" Amiga 1200. My friend ditched his Amiga 500+ and bought a 486 instead. His PC ran circles around my Amiga, no matter how hard I refused to believe it...
I had Amiga1200 and PC 486 DX2-66 MHz
Despite the fact it could render 3D images with enormous more speed than A1200, and it could handle 3D graphics better than Amiga1200 (Frontier game for example) it was too slow on bitmaps, and not only real 24 bit.
Also I had 8bit audio Soundblaster that rendered audio in Fm... It was pitiful compared to Amiga audio 8bit real DAC.
When using serious programs such as Ventura Publisher (in DOS with its own GUI interface) and other software in Windows, then it was totally not responsive to user... What a waste of power...
Once I tried a floppy version of QNX on my 486 PC... I was astonished! It flied....
Sure MS-DOS and Windows were the real snails that blocked the real power hidden in 486 Processor!
