Lightroom V 9.2 ARM Denoise on a new Asus Snapdragon X2 Extreme performance

So I just received my new ASUS Zenbook A16 with the new Snapdragon X2 Extreme processor with 48GB Ram.

I Just started running the latest version of LR V. 9.2 for ARM. Overall the performance has been quite good yet unfortunately doing a denoise on my Sony A1ll raw files is still extremely slow. Even though when I click on “Denoise” it gives me an estimate time of 19 seconds yet its taking about 3 minutes to denoise one image.

I was really hoping with the new X2 Extreme chip that performance would be improved yet for now its quite dismal

    Hi @Astonishing_Dolphin16B7,


    Thanks for sharing your experience with the new Snapdragon X2 Extreme system. I checked this internally with the product team, and what you’re seeing is currently expected behavior on Windows ARM systems.


    At the moment, AI Denoise on ARM devices may not fully utilize the GPU during processing due to the chip limitation. In those cases, Lightroom automatically switches to a more stable processing path to avoid crashes or instability during Denoise operations, to give a smoother workflow experience.

    Because of that fallback behavior:

    • The estimated processing time may appear short initially, ~19 seconds

    • But the actual Denoise operation can take significantly longer than expected on large RAW files like Sony A1 II images

    So while general Lightroom performance on the new ARM hardware is already quite good, AI Denoise performance is still being optimized for these newer Windows ARM platforms.

    I've passed your feedback to the product team internally.


    Best,

    Anshul Saini
