AMD: 3D technology for Zen 3 processors

While Zen 4 is not expected to arrive until the 2nd half of 2022, AMD unveils a new processor with 3D technology to keep people waiting.

A jump in performance without changing the architecture

At Computex 2021, AMD announced several products, new APUs for the consumer market and their RDNA2 graphics cards for mobile. The brand also took the opportunity to show a brand new processor using the Zen 3 architecture, equipped with packaging technology: theAMD 3D Chiplet Technology. AMD packaging Almost every two years, AMD has launched a new packaging system, moving from the 2.5D implementation of HBM on graphics cards to the adoption of multichip and chiplets in almost all their products. Thus, the next evolution that was announced in March 2020 at the AMD Financial Analyst Day was the X3D technology. Its first application has been unveiled: the massive addition of cache! Rendu 3D technologie X3D AMD Through a prototype shown on stage, AMD unveiled a Zen 3 processor using this technique. Each chiplet will have 96 MB of cache stacked on top of them, and thus 192 MB for a processor using 2 chiplets (as demonstrated with a 5900X). All this would allow significant gains. Chips stacked on top of each other, benefit from a large increase in bandwidth, a higher density as well as an improvement in energy efficiency. AMD benchmark zen 3D AMD announces an average 15% increase in performance on video games at identical frequencies thanks to X3D technology (call 3D V-CACHE technology), without any change in architecture. This new generation will be ready for production at the end of the year, what to compete with Intel and their Alder Lake while waiting for Zen 4?
