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?
