[comp.arch] Intel RISC CPU/80486 : do they exist ?

mch@computing-maths.cardiff.ac.uk (Major Kano) (04/30/88)

   Every so often these last few months there have been rumours of an INTEL
RISC cpu. Is there anyone out there who

1) Knows anything about this
2) Can tell us ANYTHING without infringing legal or moral "we haven't announced
   it yet so we're not saying much" restrictions (NOT MUCH  does not, of course,
   imply NOTHING)

Even affirmation or denial of these rumours would be something !
 
Same goes for the 80486.

Yours hopefully,

-mch

I should point out here, with regard to various RISC discussions, that I do
** NOT ** mean the 80960  ! This rumour was about a "real" processor, not a
process control machine.

Excuse me, but would you mind explaining what the difference is between
the 80960 and a '"real" processor'?  For that matter, I'd even be interested
in the difference between a 'process control machine' and a '"real" processor'.

The 80960 runs at 7-10 MIPS, includes a family member with support for paged 
virtual-memory systems, and is based on an architecture that has headroom
to expand to 20-30 MIPS in the near future.  In what way is it not real.

In fact, it is more real than most RISC chips (need I mention names), as it
is available in full-speed *production* quantities today, bug-free.  And
with software tools.

I wouldn't hold my breath for the announcement of another 32-bit
general-purpose RISC CPU architecture from Intel in the near future.

Apropos the 486, what we are allowed to say is:

	1) it will be compatible with the 386;
	2) it will be faster than the 386;
	3) it will be available in the future;

You will hear claims that the 486 uses "RISC design techniques" to reduce
the number of clocks per instruction.  Do not misinterpret this as a statement
that the *86 family is suddenly a RISC architecture.

I suggest that you contact your nearest Intel Sales Office  
(Intel UK, Pipers Way, Swindown, Wiltshire SN3 1RJ; (0793) 69 60 00)
for more information.
