Intel's separate Turbo Boost Max 3.0 figures are not asserted as Mac Pro system capabilities.	Single 733/867 MHz or dual 800 MHz PowerPC G4. Each processor has 256 KB on-chip L2 cache; 733 MHz has no L3, while 867 MHz and dual 800 MHz have 2 MB L3 per processor running at one-quarter clock speed. 133 MHz system bus. Generic chip records omit unverified supplier.
GPU
GPU	One MPX module per listed configuration. Launch options were Radeon Pro 580X (8 GB GDDR5), Vega II (32 GB HBM2) and Vega II Duo (two GPUs with 32 GB HBM2 each). Later maker-listed options include W5500X and W6600X (8 GB GDDR6), W5700X (16 GB GDDR6), W6800X and W6900X (32 GB GDDR6), and W6800X Duo (two GPUs with 32 GB GDDR6 each). Two MPX bays support up to four GPUs; Apple confirms upgrades to two Vega II or two Vega II Duo modules, and an Infinity Fabric Link between two W6800X Duo modules. GPU memory is not pooled into one GPU's capacity.	Single-processor models: NVIDIA GeForce2 MX 32 MB. Dual 800 MHz: GeForce2 MX TwinView 64 MB with simultaneous ADC and VGA displays. Optional GeForce3 64 MB DDR listed separately, not expanded into unproven stock combinations.
Memory type
Memory type	Twelve user-accessible DIMM slots for DDR4 ECC memory; 32, 48, 96, 192, 384 or 768 GB. 1.5 TB requires the 24-core or 28-core processor. Memory runs at 2666 MHz with the 8-core CPU and 2933 MHz with the other CPUs. 768 GB uses six 128 GB or twelve 64 GB modules; 1.5 TB uses twelve 128 GB modules.	128 MB PC133 SDRAM on 733/867 MHz, 256 MB on dual 800 MHz. Three DIMM slots support up to 1.5 GB; base and maximum rows retain each stock drive and graphics card.
Storage type
Storage type	T2-encrypted SSD storage; 256 GB, 512 GB, 1 TB, 2 TB, 4 TB or 8 TB. The 256 GB and 512 GB versions use one module; larger capacities use two modules of half the total capacity. Apple states up to 3.4 GB/s sequential reads and writes. The current 512 GB option was not listed in Sound On Sound's original configuration table.	733 MHz: 40 GB 5400 rpm Ultra ATA/66 and 12x/10x/32x CD-RW. 867 MHz: 60 GB 7200 rpm; dual 800 MHz: 80 GB 7200 rpm, both with SuperDrive (DVD-R 2x, CD-R 8x). Optional Combo drive, Zip 250 and SCSI 36/72 GB choices remain in details. Three hard-drive bays support two ATA or three SCSI drives.
Expansion slots
Expansion slots	Eight PCI Express Gen 3 slots; two MPX bays provide x16 graphics and x8 Thunderbolt bandwidth each, with up to 500 W for an MPX module. Three additional full-length slots provide one x16 and two x8 links; the half-length x4 slot holds the Apple I/O card. Optional Afterburner x16 card accelerates ProRes and ProRes RAW in supported applications; current maker tests report up to six 8K ProRes RAW or 23 4K ProRes RAW streams, compared with the lower figures in the initial announcement.	Four full-length 64-bit 33 MHz PCI slots plus dedicated AGP 4x graphics slot.

Graphics ports vary by MPX module; 580X, W5500X and W6600X have two HDMI ports, while the other listed modules have four Thunderbolt 3 ports and one HDMI port. The chassis port counts above exclude graphics-module ports. TechRadar and The Verge describe an additional internal USB-A port for a software dongle.	Two USB chassis ports at 12 Mbps each, two FireWire 400, Gigabit Ethernet, 56K V.90 modem, ADC and VGA. Optional 11 Mbps AirPort card. Headphone and Apple Pro Speakers minijacks; no analog audio input. Keyboard USB ports excluded.
External displays
External displays	Display limits depend on the graphics configuration. One 580X supports six 4K displays, two 5K displays or two Pro Display XDRs; W5500X supports four 4K, one 5K or one XDR, and W6600X four 4K, two 5K or two XDRs. W5700X, W6800X and W6900X support six 4K, three 5K or three XDRs per module. Vega II supports six 4K, three 5K or two XDRs; Vega II Duo eight 4K, four 5K or four XDRs. W6800X Duo supports eight 4K, four 5K or six XDRs. Apple's dedicated current Vega II Duo guide confirms two modules can drive twelve 4K, six 5K or six XDR displays; port and bus placement restrictions apply.	TwinView supports one ADC and one VGA display simultaneously on dual 800 MHz; no simultaneous-display assumption for the standard single-processor card.

Size and weight detail
Size and weight detail	Apple's UK and US sheets publish height 52.9 cm, width 45.0 cm and depth 21.8 cm for the tower with feet, but the width and depth labels appear transposed relative to the maker's front and side image. Main dimensions are omitted pending resolution. The US sheet gives 55.7 cm height with optional wheels. Weight varies by configuration and manufacturing process; rack enclosure specifications are separate.	Maker reference weight 14.1 kg, configuration-dependent; height 43.2, width 22.6, depth 46.7 cm.
Power supply
Power supply	1.4 kW supply; maximum continuous output 1280 W at 108–125 V or 220–240 V, and 1180 W at 100–107 V. AC input 100–125 V at 12 A or 220–240 V at 6 A; 50–60 Hz.	Maximum continuous power 360 W.
Noise
Noise	Regional maker acoustic tables differ; UK reports 2.5 B sound power at idle and during wireless web, while US reports 2.7 B and 11 dB operator-position sound pressure. Both describe a 12-core configuration with 48 GB memory, Vega II graphics and a 256 GB SSD.	–
