The Power Macintosh 7500/100 was one of the machines of the
second wave of PowerMacs. It was considered a mid-level machine
and was part of the group of computers which comprised the
7200 at the low end and the 8500 and 9500 at the high end.
The 7500 has a 601 PowerPC processor clocked at 100Mhz. The
601 processor is relatively slow and was already outclassed
by other processors at the time of its use in this machine.
The 601 was abandoned with the next generation of PowerMacs.The
7500's processor resides on a separate daughter card making
it easily upgradable to a faster processor.
The 7500 was a very popular machine and one of the first
to offer such easy upgradability. The machine is easy to get
into and sports 3 PCI slots, an extra drive bay and 8 memory
slots for a total possible capacity of 512MB of RAM.
The machine shipped with 2MB of video RAM and the ability
to add 2 more. It shipped without a L2 cache, but had an empty
slot for adding a cache chip.
Adding a 512K L2 cache should gain you an approximately 18%
processor speed improvement, although finding one that works
properly in the 7500 has proved a problem for some owners.
Make sure that the cache you consider buying is guaranteed
to work properly in your machine.
** 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. For example, in our tests, encoding
a QuickTime movie took half the time using a G4 processor
upgrade over a similarly clocked G3. Using certain Photoshop
filters or a SoundJam MP3 encoding, took 2/3 of the time.
Keep this in mind when evaluating the scores below.
