Sun IPC - The
first Sun "macintosh" integrated SPARC chip (a Tsunami I
believe) and had small form factor "shoebox". THe LX version is the
desirable one.

The IPC is about Sparc1 performance 30 pin Simms Sparc1 class processor.
The IPX is about Sparc2 performance 72 pin Simms Sparc2 class processor.
The SparcClassic and Sparc LX are follow ups to the IPX. The
Sparc IPX seems to be the desireable one since it's got the best
(I was told) sound support for NetBSD. The Classic and LX use some
different chips.
IPC is, IIRC, the same performance as a Sparc 1+.
The IPX should be exactly the same performance as a Sparc 2, since it is
really just a 2 with integrated CG6 frame buffer.
The Classic and LX are sun4m architecture. I seem to recall them having
faster clock speeds, but about equivalent performance to the IPX
(cache and other differences).
NetBSD supports audio on all the sun4c boxes (1/1+/2/IPC/IPX/SLC/ELC). It
is not supported on the sun4m boxes (SparcClassic and later) as there is
supposedly no enough public info on the AT&T chips used for the audio/ISDN.
(Actually, there may be one exception- a sun4m with 4c audio hardware, but
I forget which one. Does S/Linux support audio yet?
