Actually I think the only 8bit CPU that was properly upgraded and still have some potential real life usage is the Z80.
While 6800 was upgraded to the more complex 68000, the Z80 has a derivative that has the speed and the simplicity ( eZ80), not to mention the pipeline command processing.
(but there were not so good Z80 derivatives, like the almost never used 16bit Z8000, or z80000 (i386 equivalent)
Motorola 6800 likne died out with 60060, and PowerPCs are a kind of different (but my Xbob360 is using a kind of derivative of that PowerPC line-up)
MOS 6502 has the 65816 (still avauilable), and would be nice to compare it to eZ80.
Too bad, that I cannot name a single computer utilizing the 50 Mhz eZ80, to compare this 8 bit beast to the mentioned CPUs or to 16 bit 386DX line
