- I think that the PC Week article states that Intel is incorporating the
- features into its main product lines. That would imply a stronger
- commitment to these features than a product designed for portable
- computing.
-
- Another interesting article comparing the Intel486 SX processor and the
- Cyrix SLC is in InfoWorld December 21 page 48 "Reviews/Product
- Comparisons: 25-MHz 486 Notebooks". InfoWorld seems to come to the
- conclusion that the Intel486 SX processors are 35% to 40% FASTER than
- the Cyrix parts. They use several examples but the most powerful is two
- machines from TI: TravelMate 4000 WinSX/25 and the TravelMate WinSLC.
- Both weigh 6 pounds with battery. Similarly configured machines yield
- SYSmark92 results of 75.93 (Intel486 SX) and 47.23 (Cyrix). They
- indicate that Cyrix system "posted a SYSmark92 close to 38 percent
- slower than its 486SX/25 sibling."
-
- SYSMark92 suite is a standard set of applications that are stimulated in
- a repeatable manner using a set of commands that the BAPCo organization
- developed after talking to 5000 users of these applications. The
- applications include spreadsheets (123, Excel, Quattro), word processors
- (WordPerfect, WFW), data base (Paradox, dBase), presentation software,
- graphics applications (Harvard), software development (MSC, Borland C).
- These are the things most PC users regularly use and if not the
- composite SYSMark92 metric, then the individual catagory metrics should
- provide one with the ability to predict system performance on their
- workload.
