Teardown Update: Let's take a closer look at this custom AMD Radeon Pro 580X video card module:
-
When you pull the release latch, it engages two rollers on the opposite side, which simultaneously undock the card and push it away from the
mothershipmotherboard. -
Unlike the module itself, the silicon inside does not come out with a clever lever! A few sneaky screws are hidden under a giant sticker atop the cooling fins, and then we have to carefully disengage the lever mechanism before we can finally pull out the card.
-
For our efforts, we are rewarded with the following:
-
The main event! AMD's Radeon Pro 580X, (an iteration of their Pro 500 series for Macs) built on their 14 nm Polaris architecture, featuring 36 compute units.
-
Two rows of Micron GDDR5 VRAM, totaling 8 GB
-
2x MegaChips MCDP2920, likely something akin to their MCDP2900 DisplayPort 1.4 to HDMI 2.0 converter
-
International Rectifier IR35217 buck controller (similar to the IR35211) and NXP's L6524 I/0 expander
