Hi.

I don't exactly remember what PS/2s you were upgrading, but if it was
some 386DX based model (like 70 or 80), then you might consider the new
Cyrix 486DLC chip. It seems that there are two double clocked versions
of this chip, 16/32 MHz and 20/40MHz. The chips run externally at the
same speed (16/20MHz) as the original processor, but are double-clocked
internally (32/40MHz). This is all the info I've got on the 486DLC, but
here's an email I've saved on this topic:
------------------------------------------------------------------------
 All Cx486 chips are right now going to the OEM's. However the Cx486DLC 16/32
and 20/40 both double-clock version compatible with 16 and 20 MHz i386 (32 bit)
systems will become available to end-users (YOU) in October '92 (maybe
earlier).

 The US retail price will be $299 or less. Is this a "good" price compared to
a 486SX-25 motherboard (feel free to comment)?

 A press-release gave the following CPU benchmarks (performed on a Compaq
Desktop 386DX/16), measured before and after replacement. The last column gives
the figures of a i486SX-25 system:

	      Before	       After	     486SX-25
 Landmark 
  Speed 2.0:	20		100		85
 Norton SI:	10		40		35

 The relative speed-up in the applications Excel 3.0 (Byte Magazine Benchmark)
and Word for Windows is approx. 50% (speed-up factor 1.5).
------------------------------------------------------------------------
If you're upgrading a 286 PS/2 and don't need 486 speed, there's the
Intel SnapIn 386, a 386SX-20 with 16K cache, street price around $340.

Hope this helps,
Teemu.
