Intel 8080 vs.
6502 vs. Z80
WGF (World Geek Federation) Three Way Mashup..
I remember 6502 vs Z80 back in the day, and in the S-100 world, there
was plenty of 8080 vs Z80, but IIRC, there wasn't a lot of user
overlap between those that might run an 8080 vs the 6502.
There is always the annual C64 versus Spectrum wars on Usenet, a/k/a the
Commode versus Speculum wars, and the general discussion level is about
that intellectual.
OTOH, every so often there is true grist for the mill over processor
types. The Speccies point out correctly that the Z80 in theirs was
clocked higher, and had more registers and instructions, but the Commies
respond with the criticism that the Z80 takes more clock cycles for
typical tasks.
The consensus opinion is that the Speccy has more meat in its CPU, but
is hobbled by poor video and a merely adequate sound chip (the AY is fine,
but no SID), while the C64, while having a lower speed clock and requiring
zero page for register dependent operations, has a much better graphics
"co-processor" which hardware-assists things like sprites, and a much
better sound chip. Naturally we all know what the market chose.
I think the best example of the Z80 not at full potential was the C128.
I know Bil wanted to do more with it later on, but a lot of neat stuff
could have been realized with some relatively modest improvements. I still
like the C128 best anyway.
