The tested Revision B iMac had been updated with the hardware and
software updates, and was running Mac OS 8.5.1. The screen was set to
800 x 600 resolution and millions of colors.
The drive was not optimized before benchmarking.
Remember that benchmarks are arbitrary. They measure certain types
of performance that may or may not reflect the way you work.
Speedometer 3.06
The system was tested on 6 January 1999 with Mac OS 8.5.1 with most
inessential extensions off. The iMac was tested in 24-bit video mode at
800 x 600 resolution. Results are relative to a Mac Classic, which
rates 1.0. Numbers rounded off to one or two decimal places.
All tests were run at the default cache for a 32 MB system, which
the Memory control panel reports as about 1024KB. Virtual Memory was
set at 64 MB.
VM CPU graphics disk math
64MB 103.1 69.12 13.31 526.1
The CPU score demonstrates that the iMac is two orders of magnitude
faster than the first Macintosh.
Speedometer 4.02
The system was tested on 6 January 1999 with Mac OS 8.5.1 with most
inessential extensions off. The iMac was tested in 24-bit video mode at
800 x 600 resolution. Results are relative to a Quadra 605, which rates
1.0. Numbers rounded off to one or two decimal places.
All tests were run at the default cache for a 32 MB system, which
the Memory control panel reports as about 1024KB. The variable was
Virtual Memory, which was off in the first test, set to 33 MB in the
second, and bumped to 64 MB in the third.
VM CPU graphics disk math
off 15.22 n/a 2.52 644.7
33MB 15.26 n/a 2.64 641.9
64MB 15.13 n/a 2.56 641.9
More than anything else, these results demonstrate that when running
a single program that comfortably fits within memory, use of virtual
memory makes no significant difference in performance. All results are
within 1% of each other.
