- 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.
