The two processors were tied at around 26,000 points in the previously leaked benchmarks, but now the Alder Lake model breaks the 30,000 point threshold. AMD users will quickly point out that the R9 5950X can easily be tweaked to score above 31,000 points, but keep in mind that the Intel CPU is not overclocked in this scenario. It does, however, benefit from increased memory bandwidth from a DDR5-5200 RAM kit.
