The graphics card on the Mac Pro 2019 is a custom AMD Radeon Pro 580X. It is fixed to a dock which releases the card when the release latch is pulled. While the module is easy to remove, however, the card itself proves to be a bit harder to detach. Once it has been detached, you will find the 14nm AMD Radeon Pro 580X card, two rows of Micron GDDR5 VRAM (total 8GB) and 2 MegaChips MCDP2920.
There’s no need for a bunch of tools to slide the casing off the Mac Pro 2019. The smaller third handle on top of it rotates with ease. Simply twisting and pulling this handle uncovers everything that’s underneath the casing. Additionally, removing the casing breaks the connection between contacts and pogo pins which terminates the power supply to the machine.
Without the need for any tools, users can easily access the DIMM slots. With a simple pull of a switch the memory cover pops up where you can see the existing RAM sticks. There are even nifty little diagrams on the insides of the RAM covers that detail where the different amounts of memory must go. A total of 12 memory sticks can be fixed within the Mac Pro 2019. Additionally, there are 8 PCIe slots. All the PCIe cards are held in place by a single switch.
The three fans are held in place to the logic board with six screws and connects along with spring contacts. The whole triple-fan module comes out conjointly. These three tower fans suck in cool air through the ‘cheese grater’-like holes and move it across the logic board through multiple heat sinks. After this, the blower fan pushes all the hot air out the back.
Many modules can be accessed without tools, and those which require tools utilise standard screws and connectors. Additionally, step numbers (for repairing certain modules) and other guidelines are present on the device itself. Modules such as the I/O board, video card and power supply are all easily removable. While the SSD is modular as well, it is proprietary, which means you cannot repair it outside of Apple.
There’s a tiny little module present between two groups of DIMM slots which actually is the speaker inside the unit. The Intel CPU is located under its heat sink and is fixed in place using some T15 Torx Plus screws. Once the unusually large logic board is released from its place, you can see a variety of chips on both sides, which includes the Intel Xeon-W processor.
