7900XTX MBA cards - How to check if your card is plagued with the 110C Junction temp issue. PSA Tech Support

So for everyone's benefit, please check and test your new 7900XTX MBA (Reference - Made by AMD) card properly to make sure you don't have the 110C Junction temp throttling issue. Just because your card seems fine in your current favourite game, it could simply be that you are playing with V-sync on at 60-120hz and not even stressing this card enough to max out the board power to 347W long enough. The test must push the card to constantly stick to its stock Board Power of 347W for 10 mins. So here is what you do:

​

  1. Select a heavy static game scene, with uncapped framerates that is not CPU bound. For example, I have been using the start screen of Uncharted 4 legacy of thieves (the skeleton hanging in a cage) at 4K max setting with V-sync off. This scene is not CPU bound in any way, and maxes board power when uncapped up to 397W if you choose to max out the power slider.
  2. Put your card on stock, turn on overlay metrics, start your game, check that the GPU Board power shows a constant 347W usage and GPU Util is 100%.
  3. Time your test, and see how the GPU and Junction temps rise in tandem. Check the delta. Mostly around 70C Junction, the GPU shows 55-58C, but then the Junction starts rising way quicker and runs away from the GPU temps. On cards with issues, the Junction will reach 110C within 6 mins, while the GPU temps would barely hit 70C at the very point.
  4. If your card hits Junction 110C, check how it throttles your board power down. In a few mins, you should see Board power down to 305-307W.
  5. Bonus Testing - try your card in both standard horizontal (GPU fans facing down) and vertical (like in a test bench - fans facing you/side) orientations. A lot of cards only exhibit the 110C Junction temps in the standard horizontal orientation, which is why almost no reviewer had this issue during testing on an open test bench.

A few tips - While Unigine Heaven benchmark (available for free to all) can push the card board power to 347W when uncapped, during scene changes, the board power and util drops and the card take longer to show the 110C Junction issues. Best test method is using a static heavy scene that does not fluctuate while maxing board power to 347W. This is a PSA for all, and best you check your cards now and report to help yourself, AMD and everyone else figure out this issue. Please share your results, and avoid snide or anecdotal remarks about how good or bad AMD is. Thank you and good luck.

Final Edit (Jan 1, 2023) - This is for posterity. Der8auer has made a detailed video analysis (https://www.youtube.com/watch?time_continue=11&v=26Lxydc-3K8&feature=emb_logo). I am just posting my own videos below for horizontal and vertical orientation testing, with my card acting very differently in the two orientations. All testing in video done on Dec. 31, 2022 with side panel open in a 23C ambient room, with stock/default driver settings:
