== Architecture and Processor ==

The Performa 6200CD uses a [[PowerPC 603]] processor running at 75 MHz with integrated FPU. The processor is a 32-bit design with a 64-bit data path.<ref>{{cite web |url=https://support.apple.com/kb/SP348 |title=Macintosh Performa 6200CD: Technical Specifications |publisher=Apple |access-date=2026-02-10}}</ref>

The internal bus architecture consists of three buses:
* A 64-bit 75 MHz bus connecting the CPU, 256 KB L2 cache, and 4 MB ROM
* A 32-bit 37.5 MHz bus connecting memory, video, and I/O controllers via the Capella bridge chip
* A 32-bit 16 MHz I/O bus managed by the PrimeTime II controller

The 6260CD and 6290CD variants use a [[PowerPC 603e]] processor at 100 MHz, with the system bus speed increased to 40 MHz.
