In this test the Ryzen 9 7950X scores 16809 points, which makes it 41% faster than the Ryzen 9 5950X and 43% faster than the Intel Core i9-12900K in the same test. WCCFTech has made a nice graph giving you a better idea of the performance.
Also listed on the graph is a leaked Intel Core i9-13900K result, which slightly beats our the Ryzen 9 7950X at 16885.2 points. Based on these scores the next generation processors from both AMD and Intel are really going to beat the current generation by a lot, at least in multi-threaded workloads.
