The Intel Core Ultra 9 285K is the objective winner of this comparison, securing victory in twelve out of sixteen measured specifications. Its most significant advantage over the AMD Ryzen 5 8500G is its L2 cache, which is 567% larger. While the AMD Ryzen 5 8500G maintains a 74% advantage in max turbo power, the Intel Core Ultra 9 285K dominates the majority of the technical categories evaluated in this assessment.

Users prioritizing raw cache capacity and superior technical specifications should choose the Intel Core Ultra 9 285K for their build. Conversely, the AMD Ryzen 5 8500G is the appropriate selection for those who specifically require the higher max turbo power provided by that processor. Your final decision should depend on whether your primary computing needs align more closely with the extensive cache architecture of the Intel option or the power profile of the AMD alternative.
