CPU20 MHz Motorola 68LC040 with integrated memory management unit and 8 KB L1 cache, but no floating-point unit32 MHz Motorola 68030 with integrated paged memory management, separate 32 MHz 68882 floating-point coprocessor and 32 KB onboard cache. Apple support specifies a 16 MHz data path; the slower IIvi and FPU-less Performa 600 are separate models
GPUBuilt-in video has 512 KB VRAM standard and supports up to 1 MB; at 640 × 480, 8-bit colour is standard and 16-bit colour requires the VRAM upgrade512 KB dedicated VRAM standard for 256 colours on the Macintosh Color Display; upgradable to 1 MB for 32,000 colours. The 5/80CD configuration includes 1 MB VRAM
Memory type4 MB on the logic board with two 72-pin SIMM slots, expandable to 68 MB4 MB soldered DRAM plus four 30-pin SIMM slots, filled in groups of four; supports up to 68 MB. 1 MB ROM; minimum SIMM speed 80 ns
Storage typeApple's specification lists internal SCSI hard drives from 80 to 500 MB, a 1.44 MB floppy drive and optional 2× CD-ROM drive1.44 MB SuperDrive and internal SCSI hard disk. UK brochure offers 4/80, 4/230 and 5/80CD configurations; the third includes AppleCD 300i double-speed CD-ROM. The other two have an empty 5.25-inch half-height drive bay
