Question

Export speed with Apple M3 Pro and Windows

Good morning, I wanted to know if it was my problem that on my Windows PC with Intel i7 13700k configuration and 32 GB of RAM and Samsung 980 Pro SSD, the image export times from Lightroom are almost twice as slow as on the MacBook Pro 14'' with Apple M3 Pro with 16GB of RAM.
How is it that a processor that on paper should be almost twice as fast is actually significantly slower? Do I have some wrong settings? Could it be a question of video card and monitor (on desktop I have two 27-inch Eizo 2k connected)?

    I do not think the Eizo displays are a factor. Although external displays do increase the demand on a GPU, two 27-inch 2K displays is a small burden these days; current GPUs like the RTX series are built to drive multiple 4K+ displays with no problem and with room left over for other graphics processing. And, your GPU seems to have a generous 16GB of graphics RAM, and two 2K displays will use only a small fraction of that. So it has to be something else.

     

    I do agree that the CPU speed is probably not much of a factor with Lightroom Classic, and it is probably more of a GPU issue. And although I just saw some M3 Pro benchmarks that looked good for Lightroom Classic export, I am still surprised that a 16GB RTX 4060 is so much slower here, that does seem wrong.

    If I can, I'll post my system data tomorrow. in any case, that screenshot isn't mine, I have a 4Gb ddr5 Sapphire Nitro RX580 and today I tried with a GeForce RTX 3050 8Gb ddr6 but nothing changed. However I also tried disconnecting the monitors and nothing changes... I don't understand

    Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut out as that is just so much dead space to us non-Techs and it takes up vast amounts of scroll space making the reply less readable and less likely that others will bother with your post.

    I tried activating it, deactivating it and doing the same thing with a GeForce 3050 but it always takes over 7 minutes compared to 4 for the M3.
    Does anyone know how this is possible? Is there some setting wrong?

    I've seen other people saying it can't be turned off, even when the box is unchecked. Haven't tested this myself.

     

    So either way, it seems the GPU speed determines this.

    By default this is done in the graphics processor (GPU) now. So that's probably the difference. You can disable this:
