An optional dock provides a maths coprocessor1.5 or 1.67 GHz PowerPC G 4 with 512 KB on-chip L 2 and 167 MHz bus. Retained sheet processor paragraph omits 1.5 GHz, but factory configuration table and UK release confirm it. Exact silicon supplier omitted.
GPU–ATI Mobility Radeon 9700 with 64 MB DDR standard; 128 MB plus dual-link DVI build-to-order restricted to 1.67 GHz. UK release higher-base bullet ambiguously mentions dual-link with 64 MB; its BTO paragraph and full sheet tie dual-link to 128 MB.
Memory type4 MB on the logic board and one Duo expansion-card slot; maximum 24 MB. Apple kits expand to 8 or 12 MB; larger capacities require third-party cards512 MB PC 2700 DDR 333 in a single SO-DIMM; two slots, maximum 2 GB.
