Fast cores beat lots of cores.
For most Lightroom Classic workflows, processor performance matters more than simply having huge numbers of CPU cores.
Lightroom benefits heavily from strong per core performance. Faster processors improve general responsiveness and help with tasks including importing images, generating previews and exporting finished photographs.
Higher core counts can improve heavily parallel tasks such as large exports, but a workstation CPU with dozens of cores isn't automatically faster in Lightroom.
That's why we don't simply recommend the most expensive CPU available.
For most photographers, a modern Intel Core Ultra 7 or AMD Ryzen 7 class processor is an excellent starting point. Higher end CPUs make sense for photographers processing very large batches, combining Lightroom with Photoshop or running other demanding creative applications.
