AMD Ryzen 7 5800X vs Intel 10th Gen Intel Core i9 10900K: Comparison
What is the difference between AMD Ryzen 7 5800X and Intel 10th Gen Intel Core i9 10900K?
On l3 cache the spread is 38%, AMD Ryzen 7 5800X 32 MB against Intel 10th Gen Intel Core i9 10900K 20 MB, so AMD Ryzen 7 5800X takes it. The benchmark result agrees. Blender Cycles (CPU) puts Intel 10th Gen Intel Core i9 10900K 13% ahead, 239 against 207 over 28 runs. AMD Ryzen 7 5800X also leads on l2 cache, 4 MB on the AMD Ryzen 7 5800X versus 2.5 MB on the Intel 10th Gen Intel Core i9 10900K. They differ on integrated graphics too, No on the AMD Ryzen 7 5800X versus Yes on the Intel 10th Gen Intel Core i9 10900K.
Who each one is for
Take the AMD Ryzen 7 5800X for desktop gaming and productivity builds wanting genuine Zen 3 architectural gains with strong single-threaded performance. Avoid it for buyers who need integrated graphics, this chip requires a discrete GPU. 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 not the one for budget-conscious buyers, the near-identical 10850K, covered elsewhere on this site, delivers very close performance for typically less.
Which is cheaper, AMD Ryzen 7 5800X or Intel 10th Gen Intel Core i9 10900K?
Cost splits them too. AMD Ryzen 7 5800X sits at $449, Intel 10th Gen Intel Core i9 10900K at $488, 9% more.
Where the two are identical
Everything else lines up. Efficiency cores, form factor, release year, market segment and smt enabled read the same on both, so those are not worth weighing. They match on 2 further specifications as well.
