Intel Core i3 12100 Linux Performance Benchmarks
Even for web browser benchmarks, the Core i3 12100 represents much better performance if you are still rocking a Core i3 7100/8100 era processor.
The power consumption isn't that much different from the Core i3 8100 on average.
With just 4 cores / 8 threads, the Core i3 12100 isn't the best for code compilation / developer boxes but it can get the job done if on a severe budget.
