NVIDIA partners are reluctant to share details about the design of the RTX 4090 or RTX 4080 boards. Most likely, there is some kind of embargo from NVIDIA about this, which has been in effect for some time after the announcement. So far, there have been no leaks of the RTX 4090 board design or actual images of the AD102 GPU.
In a short video, ZOTAC shows the RTX 4090 graphics card from the AMP Extreme AIRO line. The demo shows a completely different GPU… and it’s the GA102 from the RTX 3000 Ampere graphics cards.
Instead of just blurring that part of the image or completely obscuring the markings, ZOTAC is actually showing off an RTX 4090 sample with a GA102-350 GPU. This could confirm early rumors that the RTX 3090 Ti served as a test platform for the new series. In the early stages, partners could use the GA102 with a 450W BIOS to develop the RTX 4090.
Since the new video cards supposedly have very similar boards, the GA102 chip may be pin-compatible with the AD102. This explains the blunder of ZOTAC’s marketing department, which skipped a demo with the wrong GPU. Whether this is a mistake or a well-thought-out marketing ploy, one can only guess.
