The Power Macintosh 7300/180 was the successor to the 7600 series. With performance roughly 30-35% faster than the 7600/120 and a price that was considered competitive at the time, the 7300 brought "professional" performance to a larger audience. As an added draw to cross platform users, Apple also offered a configuration that included a 166MHz PC Compatibility Card. This, of course ate up one of the 3 PCI slots. The 7300 sported the 604e processor, clocked at 180 MHz. The 604e was the last pre-G3 chip and a solid performer. The machine is easy to get into and has 3 PCI slots, an extra drive bay and 8 memory slots for a total possible capacity of 1 GB of RAM. The

7300 shipped with 2MB of video RAM and the ability to add 2 more.


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 .5 to 4 times performance improvement over the G3, depending on the application and the functions you are trying to perform.
