The Power Macintosh 8500/150 represented a speed bump for
an already existing Macintosh model. Part of the second generation
PowerMac family it was released in the spring of 96 when there
was a great deal of competition from the then existing Macintosh
clone makers, such as Power Computing.
The 8500 was considered a good, if expensive, performer
and was a mid-level machine aimed at in-house publishing,
media authoring and technical market segments. It distinguished
itself from other machines in its class by having near broadcast
quality video circuitry built-in. The machine is capable of
24-bit video input/output and has both composite and s-video
The 8500/150 sports a 604 PowerPC processor which was the
fastest PowerPC processor at that time. The 604 processor
would last only a relatively short time, to become replaced
in successor machines by the 604e. The 8500's processor resides
on a separate daughter card making it easily upgradable to
a faster processor.
The machine has 3 PCI slots, an extra drive bay (internal
Fast SCSI - 10MBps) and 8 memory slots for a total possible
capacity of 512MB of RAM.
The 8500 shipped with 2MB of video RAM , the ability to add
2. It also had a 256K L2 cache.
Below you will find the MacBench 4.0 results for the current
processor upgrades available for this machine. Results marked
in blue indicate that benchmark results were done by us.
All other processor card results were provided by the upgrade
manufacturer. The bar graphs below express results as a
percentage of improvement over the base machine, which receives
a score of 100%. Further down the page you will find a table
with the actual MacBench score.
** Note that MacBench does not take advantage
of the Velocity Engine (AltiVec instructions) of the G4.
For AltiVec accelerated applications
you can see a 1.5 to 4 times performance improvement over
the G3, depending on the application and the functions you
are trying to perform.
