The AMD Ryzen 7 5800X3D is the first desktop processor with stacked L3 cache, delivering unmatched 96MB of L3 cache paired with incredibly fast cores to create the world’s fastest gaming desktop processor. AMD began its final stretch of the ‘Zen 3’ era by unleashing a range of new Ryzen 5000 series processors. We got as many as seven new processors from the company, with the AMD Ryzen 7 5800X3D headlining the announcements. This new octa-core chip is essentially an upgraded version of the AMD Ryzen 7 5800X3D. In this article, we’re going to take a look at the AMD Ryzen 7 5800X vs the AMD Ryzen 7 5800X3D comparison to find out which one’s the better CPU for your next PC build. AMD's premium-priced AMD Ryzen 7 5800X3D is a solid eight-core performer, but its boosts to game pep and CPU-specific performance can't quite offset the cost bump.
You're getting an extra helping of L3 cache on the AMD Ryzen 7 5800X3D instead of any major updates to the Zen 3 architecture that powers all Ryzen 5000-series CPUs. In close partnership with TSMC, AMD is placing a bank of L3 cache on top of its current chiplet design—a taste of the 3D die stacking technology that we'll see used throughout chipmaking in coming years. More L3 Cache close at hand means fewer calls out to memory elsewhere, reducing latency, and reportedly increasing gaming performance by an impressive margin.
