The benchmark was conducted by PC manufacturer Puget Systems.
Lightroom Classic 15.2 was released in February, but because Lightroom Classic had a bug that caused a significant performance drop when exporting from version 15.0 onwards, Puget Systems refrained from running benchmarks until the issue was fixed. This bug has now been 'almost' resolved in the update, so the benchmarks are being run again.
The benchmark steps are as follows: First, we import 250 photos from a single camera and measure the time it takes to import them without generating previews. Next, we measure the time required to generate smart previews for those images. After that, we measure the time it takes to export those images in JPEG and then DNG format. This process is repeated with photos from three other cameras. Next, we import multiple photosets and use Lightroom's AI tools to perform operations such as subject selection and super resolution, measuring the time it takes for each. Finally, we convert these times into a score. These runs are run on multiple combinations of CPUs and GPUs.
The overall scores for the CPU alone are as follows. Of the configurations tested, the Intel Core Ultra 7 265K delivered the best performance, followed by the Intel Core Ultra 9 285K . Puget Systems notes, 'Most applications in Lightroom Classic are relatively lightly threaded, so a processor with a higher core count may be less useful than many other applications.'
The ranking of import times is as follows: The AMD Ryzen 7 9850X3D and the
For export, the
Puget Systems states, 'The Intel Core Ultra 7 265K offers excellent performance for the price in Lightroom Classic overall, so we recommend it for most workstations. Those who are willing to invest can also consider the AMD Ryzen Threadripper 9970X, but we believe it is overkill for most photographers. Another option is the AMD Ryzen 7 9850X3D, which offers the best performance for AI tasks and is the fastest Photoshop CPU we have tested. However, those looking for AI performance should upgrade their GPU first, as shown in the following results. '
The overall GPU scores are as follows. The NVIDIA RTX 5090, RTX 5080, and RTX 5070 were ranked from top to bottom. However, there was little difference, with the RTX 5060 and Intel Arc B580 performing slightly worse. Puget Systems also noted that 'the Intel Arc B580 has a relatively good price-performance ratio due to its low price.'
The AI scores are as follows: The RTX 5070 dropped slightly, while the RTX 5070 Ti rose to second place. 'Based on this data, we can say that the 5070 Ti is at the sweet spot in price/performance for Lightroom Classic AI workflows,' Puget Systems said.
Since importing does not use GPU acceleration, it can be said that there is no performance difference depending on the GPU.
Even in JPEG export, the difference between the fastest and slowest models was large, but most GPUs performed very similarly, suggesting a slight CPU bottleneck. All GPU tests were performed on an AMD Ryzen 9950X3D.
Puget Systems states, 'From this data, we can see that the NVIDIA GeForce RTX 5070 Ti is the GPU with the best price-performance balance. On the other hand, the RTX 5090 may also be worthwhile for users who use AI tasks intensively. If you're on a budget, the Intel Arc B580 is a good option, and it can save you money without sacrificing performance as much as the RTX 5060.'
