Material analysis in detail: NVIDIA RTX 4080 Super Founders Edition 16GB
The card relies on a large vapor chamber made of nickel-plated copper. The surface shows slight traces of processing, but this can be compensated for quite well.
This is done with a good phase changer pad, which in this case consists of corundum (Al2O3) and zinc oxide in a ratio of around 85:15. You can’t do any better with normal thermal conductive pastes, no matter what they say on them.
The memory is mounted on nickel-plated aluminum heatsinks, which Foxconn soldered onto the chamber as the manufacturer. MSI made this out of copper, here we only have aluminum.
The pads for the memory are white crumb pads with a textile insert, but only as an aluminum oxide-silicone mixture with a textile insert to keep the shape.
The heat sinks for the MOSFETs are also only made of nickel-plated aluminum, but this is sufficient because the very efficient so-called Smart Power Stages are almost oversized with their 70 amps. The pads are then the same as for the memory.
The body is made of black anodized aluminium and Foxconn has dispensed with the usual alloy of aluminium and silicon.
The backplate is also made of anodized aluminium, so once again the usual.
The GPU clamping cross is made of beautiful, blackened spring steel with an alloy of iron, chrome and nickel.
That concludes this first part of the analysis and, as you can see on the next page, the card from MSI
