The 68060 will be available to
developers in the first quarter of
1994 (from what I read they will have
them before that time so that they can
have products that use the 68060
available for sale in the first
quarter of 1994). The price is
supposed to be something like $500 per
chip! That's a bit expensive so let
me tell you what it can do;
68060 has the ability to execute more
than one instruction per clock cycle
due to two parallel instruction
pipelines for integer instruction and
also a third pipeline for floating
point instructions. The chip also has
the ability to do branch prediction to
increase speed even more.
The 060 will be available at 50Mhz
(resulting in a performance of 77Mips
and 10Mflops) and also a 66Mhz
(resulting in a performance of 102Mips
and 14Mflops). An interesting thing
to note is that that is the
performance with current software
(developed with compilers that are
unaware of the 68060) because the chip
is designed to execute multiple
instructions per clock cycle it would
be possible to increase the Mips
rating by changing compilers so that
they could take advantage of this
feature. If code was written to take
advantage of this ability it may be
possible to get up to 100Mips from the
50Mhz chip and 130Mips from the 66Mhz.
There have also been some rumours that
stated that Motorola would also
produce a 100Mhz version of the chip
but that is only a rumour as far as I
know.

Some other features of the 060 are
dual 8K cache, 0.5 micron static cmos
allowing for lower heat operation and
the ability for the chip to run from a
3.3 volt power supply in notebook type
computers The Intel Pentium is based
on older 0.8 micron and does not have
these features. Also the Pentium
requires more transistors on chip to
remain compatibility with earlier
Intel chips which adds to the heat
problem. The Pentium has something
like 3.2 million transistors with
larger 0.8 micron spacing and the 060
gets the same performance with 2
million transistors and tighter 0.5
micron spacing. The closer you get
the transistors together and the fewer
you have the lower the operating temp.
of the chip AND the higher the
frequency you can run the clock at.

It seems there is some discrepancy in
the MFlops you're going to get out of
one. Well from what I gather, no one
but Motorola really knows for sure,
but you'll get anywhere from 10-16
MFlops for the 50 Mhz 060 and 14-20
MFlops for to 66 Mhz 060, depending on
your compiler and a lot of other
things. Either way, its going to make
one hell of an Amiga.
@5
One more thing, the Pentium has 8
32bit integer registers and 8 64bit
floating point register. The 060 has
16 32bit integer registers and 16
64bit floating point registers. What
this means is that Intel still sucks
and that Motorola is still awesome!
