<don't know why Intel's 'low cost' processors are always so bone
headed:
<486SX, which removed the one true thing that made it a 486, 8088, removing
<the crucial 16-bit bus of the 8086, 386SX, which worked pretty well, but
<still halfed the external bandwidth (did Intel ever make a cheap version o
<a 286?), and now we've got Celeron: Until the Celron A, no cache at all...
This show a fundemental lack of knowledge about Intel CPUs and their
busses.
8088 actually runs for the same clock about 20% slower than the 8086
but using significantly fewer glue chips.
The 386sx is a lower pin count 386 that uses a 16 bit bus insted of the
32bit again for lower cost and lower power. Bus bandwith was not half
as it is faster than that.
Celeron, PII with big internal cache. I just powered up a celeron 333mhz
with 128k internal cache and it's remarkably fast(and cheap).
286 never saw a 288 version.
ISA and EISA bus machines are slow as the BUS speeds are limited to ~8mhz.
This is where many older machines hit the speed wall. PCI and other
extended busses are faster (to the limits of the cpu level bus).
