CPU
CPU	16 MHz Motorola 68030 with integrated memory-management unit, 16-bit data path and 0.5 KB L1 cache; no standard floating-point coprocessor	Motorola 68030 at 33 MHz with integrated memory management and 32-bit data path; optional socketed 68882, 0.5 KB first-level cache and no second-level cache. Apple Service Guide identifies the Performa 460, 466 and 467 as the 33 MHz LC III family; these aliases are not separate product records
GPU
GPU	Built-in video with 256 KB VRAM supports 8-bit colour at 512 × 384 and 4-bit at 640 × 480; 512 KB VRAM allows 16-bit at 512 × 384 or 8-bit at 640 × 480	512 KB built-in VRAM, expandable to 768 KB with a 256 KB SIMM. A 512 KB VRAM SIMM may be fitted but only 256 KB is used. At 640 × 480 and 832 × 624, standard memory supports 8-bit colour; upgraded VRAM supports 16-bit colour
Memory type
Memory type	4 MB soldered to the logic board plus two 30-pin SIMM slots, populated as a matched pair; Apple supports 4–10 MB. With two 4 MB SIMMs, the lowest 2 MB of onboard RAM is inaccessible.	4 MB soldered RAM plus one 72-pin SIMM socket, maximum 36 MB. Apple specifies 80 ns minimum memory speed and SIMM capacities 1, 2, 4, 8, 16 or 32 MB. 1 MB ROM
Storage type
Storage type	Internal 1.44 MB floppy drive and 40 or 80 MB internal SCSI hard-drive options	Apple LC III+ support lists 80–160 MB internal SCSI hard disks and an automatic-inject 1.44 MB floppy drive. Exact original RAM/drive configuration pairing is unresolved, so structured storage capacity is omitted. Apple July 1994 Service Guide gives conflicting 80 MB and 180 MB values for Performa 460 in different tables; those are not silently assigned to this model. Performa 460-series bundles use a manual-insert SuperDrive
Expansion slots
Expansion slots	One LC processor-direct slot; an optional floating-point coprocessor card can occupy it	One LC III processor-direct expansion slot. Ethernet requires an expansion card; no built-in Ethernet

External displays
External displays	Built-in video supports 512 × 384 and 640 × 480 displays; colour depth depends on fitted VRAM	Separate monitor required. Apple specifies 512 × 384 and 640 × 400 at 16-bit colour, plus 640 × 480 and 832 × 624 with colour depth depending on VRAM capacity
