M5 vs M1 Max vs M2 Ultra - Lightroom Test - Shocking Results

[m1maverick]

Do you normally export 750 files from lightroom? Is that part of your normal workflow? What is the relevance of such a task if you (or others) rarely do it.

Running tests that may have little to no bearing on real world usage just turns into noise. How often do people export 700+ images from LR? Is it an hourly task, daily, weekly, once the project over?

The same can be said of Geek Bench yet people use it all the time.

And also people complain that the synthetic benchmarks fail to convey real world results, so much so that many of the popular tech sites augment their testing with real world usage testing criteria.

I have found that the best thing one can do for PS or LR adjustments of large files is get LOTS of ram rather than better processors (within reason). I have had LR and PS take near 100GB memory, which of course uses lots of swap, resulting in lagginess and long pauses. ...

This.

The M2 Ultra setup is the outlier at 64GB of RAM, which in reality is more than twice the M1 Max when you account for system, application, and 'cached files' allotment. If the M2 Ultra can act mostly in RAM then it's memory bandwidth advantage really comes into play, which appears to be reflected in the timings.

Also helps explain the parity between the M1 Max and the M5. Folks cite the memory bandwidth difference, but if swapping is necessary then that distinction is equaled by the similar difference, though in the other way, of the SSD speeds.

This all just comes around to what a tragedy it is that Apple charges as much for an incremental amount of additional RAM as one would pay for a full 32GB on the PC side.

I'd say his benchmark is more realistic than GB.

I photograph events such as weddings and conferences, and I regularly export hundreds of JPGS from RAW, approx 2 to 3 times a week, on average, for the last 20 years.

Further more, my network of professional photographer friends, also regularly export hundreds of JPGs from RAW on a similar basis.

So this is a very important data point for some people and I thank the OP for doing this test and providing the information.
