- No. You have muddled up what Intel means. Intel has long stated that its
- chips
- come in three versions, the standard version, the SX version which is a
- cheaper less powerful version of the standard, and the (SL? I'm not in the
- market for portables) chips which are low power versions of the standard.
-
- When pentium comes up, who knows. We might see pentiumSX's which are
- pentiums, part of whose superscalar pieces have failed and which perform
- the function of the failed region elsewhere on the chip at a cost in speed,
- and thus not quite as superscalar. This is different from either 386 SX or
- 486 SX, but the name still makes sense.
