Compared to the Core i5-11400, the 12400 is between 15-25% faster than its predecessor. There are no apples-to-apples comparisons of the two chips available for gaming workloads, but going by the single-threaded advantage of the Golden Cove cores, you can be sure that the Intel part will level with its competitor, at the very least.
CPU-Z is a close call, with the former edging past the latter in the single-threaded benchmark, and the opposite happening in the multi-threaded segment. Recently Intel released Alder Lake-based processor, the Core i9 12900K, and the platform is poised for the future with its incredibly fast performance. This is a relatively narrow range which indicates that the Intel Core i5-2400 performs reasonably consistently under varying real world conditions.
Meanwhile, both the newer versions of Cinebench see the 12400 trump the Ryzen 5 5600X in both the single-threaded and multi-threaded tests. PassMark Software has delved into the millions of benchmark results that PerformanceTest users have posted to its web site and produced a comprehensive range of CPU charts to help compare the relative speeds of different processors from Intel, AMD, Apple, Qualcomm and others. The range of scores (95th - 5th percentile) for the Intel Core i5-2400 is just 16.7. The Core i5-12400 is slightly slower in the older Cinebench R15 multi-threaded benchmark but wins in the single-threaded test. The Intel Core i5-2400 is a 'Sandy Bridge' processor.Some of the prominent capabilities of the processor include SSE 4.2 + AVX + AES + Intel VT-d.This processor has been found on since Q12011 and found in approximately 14,409 results on. The processors were compared in Cinebench R15, R20, and R23, with the former coming out on top in most tests. The Intel Core i5-2400 is a 4 thread processor configuration with 3.1GHz clock speed.
The latest leaks coming out of China indicate that the Core i5-12400 is going to be faster than the Ryzen 5 5600X, all the while being around $100 cheaper: ~$200 vs $300. Intel’s Core i5-12400 and the rest of its non-K siblings are yet to hit the market, but going by early benchmarks, it’s going to be a midrange monster.
