- NSTL Benchmarks the Macintosh IIci and Portable
-
- Apple’s Summary. NSTL performed application benchmarks comparing the Macintosh
- IIci and Portable with competitive machines. NSTL found the Macintosh IIci was
- overall about 50% faster than IBM’s and Compaq’s 25-MHz machines. NSTL found
- that the overall performance of the Macintosh Portable was above the 286
- portables but below the Zenith 386 portable.

- Introduction
-
- National Software Testing Laboratories (NSTL), a third party testing
- organization, performed benchmarks comparing the Macintosh IIci and Portable
- with competitive machines. NSTL ran many different tests for three
- applications, and then summarized the results for each application by totaling
- the individual times. The three applications tested are available in both
- Macintosh and Windows versions. This document lists NSTL’s results, and then
- concludes with Apple’s analysis of these results.

-
- Macintosh IIci—Not All 25-MHz Systems Created Equal
-
- The Macintosh IIci was faster than the 25-MHz IBM PS/2 Model 70 A21 for every
- application that NSTL benchmarked.
-
- Even though both machines offer 25-MHz processors, the Macintosh IIci was
- consistently faster than the comparable IBM system.
-
- NSTL also benchmarked the IIci using Apple’s IIci Cache Card and 8bit Video
- Card. NSTL's benchmarks showed that adding the Cache Card to the IIci
- increased its speed by an average of 23%, a very significant performance boost
- for power users. NSTL also found that adding the Video Card increased speed by
- 7%.

-
- Macintosh Portable—Performance Beat 286 Portables
-
- The competitive portable that has received the most publicity lately is the
- Compaq SLT/286.
-
- The Macintosh Portable easily beat the SLT/286 in the Excel and Illustrator
- benchmarks (it was almost twice as fast). Both were nearly equal in the
- PageMaker benchmark.
-
-
- Apple’s Summary
-
- Positioning of the IIci. NSTL compared the performance of the IIci with the
- PS/2 Model 70 and the Compaq 386/25. Averaging the results of all three
- applications shows that the IIci was about 50% faster than each of these other
- 25-MHz machines. Adding the cache card to the IIci makes it about 80% faster
- than each of the other systems. This demonstrates that factors other than
- clock speed help determine performance, such as the optimization of system
- software for running a graphical environment.
-
- Positioning of the Portable. Along with the Compaq, NSTL also ran benchmarks
- on other leading 286 portables (Zenith’s SupersPort 286 and Toshiba’s T1600) as
- well as Zenith’s TurbosPort 386. When all three benchmarks are averaged, the
- performance of the Macintosh Portable was above the 286 portables but below the
- Zenith 386 portable. Therefore, the Macintosh Portable should be positioned as
- offering performance (in a graphical environment) between 286 and 386
- portables.
-
- Macintosh optimized for graphical environments. When computers run in a
- graphics environment, they experience overhead such as windows management and
- handling various fonts. The Macintosh was designed from the start to give
- optimum performance in a graphics environment. When PC compatibles run a
- graphics environment, such as Windows, they are usually slower than Macintosh
- systems (when both are using comparable processors). This is borne out by
- NSTL’s results. The Macintosh IIci and Portable were overall faster than
- comparable competitors when both were running the same graphics-based
- applications. Since graphical environments are the industry trend, we believe
- that this Macintosh advantage will become increasingly important.
