AMD Ryzen 7 5800X3D vs Intel 10th Gen Intel Core i9 10900K: Comparison
AMD Ryzen 7 5800X3D vs Intel 10th Gen Intel Core i9 10900K: the l3 cache difference
Start with l3 cache, because it is the widest measured gap between them: AMD Ryzen 7 5800X3D 96 MB against Intel 10th Gen Intel Core i9 10900K 20 MB, 79% in favour of AMD Ryzen 7 5800X3D. The benchmark result agrees. Blender Cycles (CPU) puts Intel 10th Gen Intel Core i9 10900K 12% ahead, 239 against 210 over 28 runs. L2 cache runs the same way, 4 MB on the AMD Ryzen 7 5800X3D versus 2.5 MB on the Intel 10th Gen Intel Core i9 10900K, another win for AMD Ryzen 7 5800X3D. They differ on integrated graphics too, No on the AMD Ryzen 7 5800X3D versus Yes on the Intel 10th Gen Intel Core i9 10900K.
AMD Ryzen 7 5800X3D vs Intel 10th Gen Intel Core i9 10900K: which one fits your build
The AMD Ryzen 7 5800X3D is the one to take for mainstream desktop builds and everyday productivity, though it is not the pick for extreme overclocking (unless K/X-series) and workstation-class multi-threaded workloads. Take the Intel 10th Gen Intel Core i9 10900K for desktop gaming builds specifically wanting the highest available Comet Lake single-core clock speed. It is the wrong buy for budget-conscious buyers, the near-identical 10850K, covered elsewhere on this site, delivers very close performance for typically less.
