CPU
CPU	466/533 MHz single or dual 533 MHz G4: 1 MB backside L2 cache at half processor speed. 667/733 MHz: 256 KB on-chip L2 and 1 MB backside L3; retained 733 sheet specifies quarter-speed L3, whereas launch prose loosely says half-speed. 133 MHz system bus. Generic per-processor chip records do not infer silicon identity.	Dual models have one physical dual-core PowerPC G5 at 2 or 2.3 GHz. Quad has two physical dual-core processors at 2.5 GHz, four cores in total. Each core has 1 MB L2 cache. Front-side bus per physical processor is 1, 1.15 or 1.25 GHz respectively. Macworld’s exact Quad review describes its liquid cooling.
GPU
GPU	Stock 466 MHz: ATI RAGE 128 Pro 16 MB; stock 533/667/733 MHz: NVIDIA GeForce2 MX 32 MB. Retained options include ATI Radeon 32 MB and GeForce3 64 MB; these are not silently treated as launch stock.	Stock dual-core 2 GHz: NVIDIA GeForce 6600 LE with 128 MB GDDR SDRAM. Dual-core 2.3 GHz and Quad: NVIDIA GeForce 6600 with 256 MB GDDR SDRAM. Optional NVIDIA GeForce 7800 GT 256 MB and Quadro FX 4500 512 MB; the Quadro occupies the graphics slot and adjacent x4 slot.
Memory type
Memory type	128 MB standard on 466/533 MHz; 256 MB on 667/733 MHz. Three PC133 SDRAM DIMM slots support up to 1.5 GB; base and maximum memory retain evidenced processor/drive/graphics ties.	Stock 512 MB PC2-4200 DDR2 at 533 MHz, installed in matched pairs. Up to 16 GB supported; ECC configurations available from 1 GB. Rows retain the stock drive and graphics at base and maximum supported memory.
Storage type
Storage type	Stock 466 MHz: 30 GB 5400 rpm; 533 MHz: 40 GB 7200 rpm; 667/733 MHz: 60 GB 7200 rpm Ultra ATA/66. CD-RW 8x/4x/32x on lower configurations; 733 MHz SuperDrive writes DVD-R 2x and CD-R 8x. Current retained sheet additionally lists a 733 MHz CD-RW factory variant and omits launch 667 MHz; both distinctions retained here. Macs Only tested a maker-store dual 533 MHz with a named 30 GB downgrade from standard 40 GB; only these restricted dual configurations are included. Three drive bays; optional SCSI and independent CTO options remain in details.	Stock 160 GB on dual-core 2 GHz and 250 GB on dual-core 2.3 GHz and Quad. 7200 rpm Serial ATA drives; two internal bays. Optional one or two 500 GB drives. One optical bay with 16x SuperDrive supporting dual-layer DVD+R recording.
Expansion slots
Expansion slots	Four full-length 64-bit 33 MHz PCI slots plus dedicated AGP 4x graphics slot.	PCI Express: occupied x16 graphics slot, two open x4 slots and one open x8 slot. Older PCI and PCI-X expansion cards cannot be reused in these slots.
