Under the Hood
After removing several screws, we can remove the full-length backplate, we didn’t see any thermal pads to help sink heat away from the board like some models out there.
Four screws around the GPU die and one more not as obvious near the rear of the card hold the heatsink on. An RGB plug at the rear of the card and two fan connectors to one side need to be removed as well.
The GPU die contact area is solid copper and but the aluminum plate around it also sinks heat from the VRAM.
A total of 5 large heatsinks move heat around the assembly, four of which extend through the entire rear area.
Four more screws hold the fan shroud on the heatsink.
The front two fans share one fan header from the GPU via a splitter tucked neatly in one corner between the fans.
Apistek GA92S2U fans rated 0.45A 4-pin PWM fans are easily replaceable should one ever fail and are found online quite readily, albeit with slightly different blade geometry.
A few more screws through the rear I/O bracket hold the subframe in place. This frame cools the main VRM stages as well as providing an extra bit of structure and support to the card.
Nvidia uses six phases for a reference card but Zotac AMP’s it up to no less than ten phases.
There is another smaller VRM at the front of the card. We’re not sure if it’s for the memory, but it is most likely for the power delivery feature of the USB Type-C Virtual Link port on the rear of the card.
Eight memory IC’s surround the GPU die.
Each memory module is a Micron 1GB GDDR6 module.
The obligatory Die-shot. Our Zotac RTX 2070 AMP Extreme carries not only the TU106-400 designation but also a new ‘A’ in the part number. Nvidia is pre-screening dies this generation into two bins, the more capable dies carry the ‘A’ designation while the ones used on the stock, non-overclocked cards are minus this character.
