Internal Comparison System Notes
AIBB's internal default comparison systems were selected to give a
broad overview of a number of system configurations and hardware types.
They represent the broadest base of default type systems (eg, not third-
party enhanced). These systems are as shown below:
A600-NF
An Amiga 600 system with no FAST RAM ( NF ) complement. This
is an all CHIP RAM based machine, and is provided here to give a
comparison towards systems utilizing only CHIP RAM. This is a
stock machine, with accelerator devices or other additional
enhancements. AmigaOS 2.x was the operating system used and was
located in ROM.
A1200-NF
Commodore's low-end AGA machine, the Amiga 1200, was used to
gather the data for this system. No FAST RAM was used in this
machine, and AmigaOS 3.0 ( V39.106 ) in ROM was the operating
system present
A3000-25
The comparison data here was obtained from a 25 MHz CPU rated
system, which utilizes the MC68030 CPU and MC68882 FPU as it's
processing engines, and equipped with static-column (BURST mode
capable) FAST RAM. AmigaOS 2.x was the operating system in use,
and was located in ROM on the system A3000's motherboard.
A4000-25
An Amiga 4000 utilizing a 25 MHz 68040 CPU (stock configuration)
was utilized to obtain comparison data. AmigaOS 3.0 was utilized
as the system OS ( V39.106 ) and was located in ROM on the
motherboard.
It should be kept in mind that all parameters for each system should
be noted when making comparisons by checking the statistics located
on AIBB's System Information Display. This is especially true if you are
comparing a similar based machine to one contained within AIBB. Various
parameters can alter performance significantly and need to be accounted
for when making fair checks. For example, no systems here were utilizing
such performance enhancements as CPUBlit (A program designed to enhance
performance by using the CPU instead of the Blitter for certain operations),
or utilizing an OS image contained in RAM (which can be faster than ROM
images under certain circumstances).
Operating system versions are also important to keep in mind. AmigaOS
3.0 is significantly more optimized in certain graphics respects than its
predecessors, and may show up as a significant performance boost in
graphics-related tests over a similarly equipped system running a lower OS
version. (All systems save for the A4000 here were utilizing the AmigaOS
2.04 mask ROM as their operating system kernel environment...the latter
A4000 was utilizing AmigaOS 3.0 contained in ROM).
One other important aspect of performance regarding the Amiga which has
come more seriously to light is the question of display parameter effects
on test results. With the advent of the AGA chipset and the new display
modes it contains, a great deal more care must be taken when making system
comparisons because of the system bus bandwidth limiting effects some
modes may have. Please do make sure to note the display mode used on
the default systems contained here when comparing systems. Also, when
making modules or test result notes, it is wise to carefully monitor what
types of screens are currently in use and displayed when AIBB is performing
tests.
