The Power Macintosh 9600/300 came out when Apple was facing some stiff competition from clone manufacturers. This perhaps explains the numerous improvements in this machine over previous 9600's. The Level 2 cache was increased from 512k to 1MB and moved from the logic board to the processor card where it could communicate with the processor at 100MHz. VRAM was also doubled from 4MB to 8MB allowing 24 bit color on 21" monitors. Continuing with the doubling theme, the CD-ROM drive was bumped from 12x to 24x and the minimum RAM configuration was bolstered to a respectable 64MB, up from 32MB. Also new to the 9600 line was onboard Ethernet and an internal Zip drive. Unfortunately with the 9600/300 Apple discontinued use of the faster Seagate Barracuda drive in favor of slower IBM and Quantum drives. Of course all of these changes came when the new G3 machines were starting to make their debut. Many Mac publications while hailing the many improvements in the 9600/300 were quick to point out that the new G3 machines were much quicker in most respects. That said, the 9600 is still a real workhorse and of course is that there are plenty of G3 upgrade options for this machine. You should note that the processor scores for the upgraded 9600/300 are nowhere near as striking as on our 9600/200 Upgrade Page. A testament to the zippy 300MHz 604e processor and new 1MB "inline cache" design.

Below you will find the MacBench 4.0 results for most of the processor upgrades available for this machine. These results are what the individual manufactures publish for their cards. In other words the speed trials were run by the manufacturer. For an independent evaluation of these cards check the Processor Upgrade Page to see if we have results available. 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 scores.
