The 8100 family of PowerMacs came in three flavors: a 80Mhz model, a 100Mhz model and a 110Mhz model. In addition the 80Mhz and 100Mhz models could be purchased as AV machines which meant that the PDS slot contained a AV card with 2MB of VRAM, rather the standard PDS video card that came with other models. When they were introduced, the 8100's were Apple's top of the line machines, marketed primarily to high-end DTP, graphics, prepress and multimedia professionals.

The brain of the machines is the 601 PowerPC chip (which was soon to become eclipsed by the 604 and 603 chips that followed). The 8100/110 sported an enhanced version of the 601, the 601+, that was smaller, used less power and ran cooler than the standard 601.

The machines come with 3 NuBus slots, which are somewhat hamstrung on the two slower machines. Three factors contributed to throughput that was less than half that of a high end Quadra: flawed controller circuitry and ROMs, and a clock speed that that did not synchronize well with the 20MHz NuBus. The controller chip on the 100 and 110 models were redesigned making for better performance and more stability with many high-end NuBus cards.

 

 

 

 

 

 

Installed RAM varied from 8MB to 16MB and in all cases 8MB of RAM is soldered to the motherboard. RAM must be installed in pairs and maximum RAM is 264MB. There are 8 RAM slots. The machines came with 256K of L2 cache. Standard VRAM was 2MB but can be expanded to 4MB. Hard drive sizes range from 250MB to 1GB and some models came with 2X CD-ROM drives. The 8100's tower cases have one free drive bay which can accommodate 1 full height drive or two half height drives. Machines without a CD-ROM drive had an extra free drive bay available. Internal SCSI support andstandard Ethernet are onboard.

 

Below you will find the MacBench 4.0 results for all of the current processor upgrades available for this machine. Results marked in Red indicate that benchmark results we provided by the upgrade manufacturer. All other results are from the results of our own testing. 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.
