Released	1993	–
Performance
Processor
Processor	Motorola 68LC040 20 MHz (Macintosh Centris 610)	68030 32 MHz (Macintosh Performa 600)

CPU cores	1	1
Memory
Memory	4 MB	4 MB or 5 MB (better)
Storage
Storage	80 MB	160 MB (better)
CPU
CPU	20 MHz Motorola 68LC040 with integrated memory management unit and 8 KB L1 cache, but no floating-point unit	Motorola 68030 advertised as 32 MHz; Apple TIL 10681 gives the exact 31.3344 MHz clock. Integrated paged memory management, optional socketed 68882 at the same clock, and no external RAM cache. This is distinct from the 16 MHz IIvi and the IIvx with its standard FPU and 32 KB cache
GPU
GPU	Built-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 upgrade	Performa 600 has 512 KB VRAM; 600CD includes 1 MB. Supports 640 × 480 at 8-bit colour with 512 KB, or 16-bit colour with 1 MB; 512 × 384 RGB supports 16-bit colour with either capacity. Optional NuBus display cards support other monitors
Memory type
Memory type	4 MB on the logic board with two 72-pin SIMM slots, expandable to 68 MB	4 MB soldered DRAM and four 30-pin SIMM slots, expandable to 68 MB with 80 ns or faster fast-page-mode memory. All four expansion SIMMs must have matching capacity and speed. 1 MB ROM and 256-byte parameter RAM
Storage type
Storage type	Apple's specification lists internal SCSI hard drives from 80 to 500 MB, a 1.44 MB floppy drive and optional 2× CD-ROM drive	Both original brochure configurations include a 160 MB internal SCSI hard disk and 1.4 MB SuperDrive. 600CD adds an AppleCD 300i double-speed CD-ROM drive with multisession Photo CD support; standard 600 leaves its half-height 5.25-inch bay free. Apple supports 80–400 MB internal hard drives; this supported range is not presented as extra factory configurations
Expansion slots
Expansion slots	One expansion position for either a seven-inch NuBus card or a processor-direct-slot card, using the appropriate adapter	Three NuBus slots and a separate processor-direct accelerator slot. No built-in Ethernet; LocalTalk uses the serial ports. Internal SCSI expansion bay and support for up to six external SCSI devices

Size and weight detail
Size and weight detail	Apple lists a weight of 14 lb	Apple specifies 25 lb (11.3 kg), 6 inches high, 13 inches wide and 16.5 inches deep. TIL 10681 prints an inconsistent metric height of 152 cm beside 6 inches; dimensions_mm is omitted rather than silently correcting that source
Power supply
Power supply	–	Apple TIL 10681 states 100–240 V AC, 50–60 Hz and 112 W maximum excluding monitor; it also gives 112 W maximum DC output. Current archived support lists 230 W maximum and shared Service Source gives 200 W AC and 112 W DC. These differing ratings are retained without selecting a single headline consumption figure
In the box
In the box	Apple lists 10 February 1993 as introduction; a distinct first-sale date was not established. The 86 W specification is power-supply capacity, not measured running consumption.	System 7.1P for the Performa 600, At Ease, Macintosh PC Exchange and application software varying by retailer. Apple introduced it on 14 September 1992; the original launch planned later availability, and an actual first retail date has not been independently established, so released is omitted

Ports
Ports	–	Headphone jack
Back ports
Back ports	Two Apple Desktop Bus ports, two serial ports, external DB-25 SCSI, DB-15 video, audio input and output; Apple AUI Ethernet was optional	Two ADB ports, DB-15 video, DB-25 SCSI, two mini-DIN-8 RS-232/RS-422 serial ports, mono sound input and sound output. Serial maximum 230.4 kbit/s, or 0.920 Mbit/s with an external clock
External displays
External displays	–	Separate display required; the original brochure shows an optional 14-inch Performa Plus Display. Built-in video also supports the published Apple 12-inch monochrome/RGB, AppleColor High-Resolution RGB and Macintosh Color displays, plus 640 × 480 VGA with an appropriate adaptor
Speakers
