The AMD Ryzen 7 9800X3D is the objective winner of this comparison, securing nine spec victories against the three held by the AMD Ryzen 5 8500G. The most significant technical advantage for the winning processor is its L3 cache, which is 500% larger than that of its counterpart. While the AMD Ryzen 5 8500G maintains a lead in MSRP, which is 63% better than the alternative, the superior cache capacity establishes the AMD Ryzen 7 9800X3D as the more capable hardware option.

Users prioritizing raw technical specifications and the substantial L3 cache advantage should select the AMD Ryzen 7 9800X3D for their build. Conversely, the AMD Ryzen 5 8500G is the appropriate choice for budget-conscious buyers who value the 63% better MSRP over the performance-oriented features found in the higher-tier model. Selecting between these two components depends entirely on whether your primary requirement is the increased cache capacity or the more favorable initial purchase cost.
