Yes, pretty misleading alltogether. While CBM sold 14 MHz clocked A1200 to their very end (and after that ;-)) as low end, higher clocked i486 were only becoming available/common at the end of CBM. The i486DX2/66 was introduced in March '92, the i486DX4/100 in March '94, according to
http://en.wikipedia.org/wiki/List_of_Intel_microprocessors#80486DX which matches my memory.
Faster 486s were pretty expensive when CBM still existed, so slow 486s and fast 386s were more common in the early 90s - and those compared not too well against similarly priced Amigas...
