GPU512 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 colourIntegrated 1 MB DRAM video supports 640 × 480 at 16-bit colour or 832 × 624 at 8-bit colour through the DB-15 monitor port

Storage typeApple 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 SuperDrive1.2 GB internal IDE hard drive, 1.44 MB floppy drive and 4× CD-ROM drive
