AMD’s Ryzen 9 7950X3D is the quickest gaming CPU on the planet on account of AMD’s determination to convey its disruptive 3D chip stacking expertise to Zen 4, however curiously, the corporate hasn’t shared any particulars concerning the new Second-Gen 3D V-Cache. Within the Ryzen 7000X3D informational supplies. Initially, we discovered some particulars at a latest tech convention we included in our assessment, and now AMD has lastly answered a number of of our follow-up questions and the chip stays within the 7nm course of and now has a peak bandwidth of as much as 2.5TB/s, first-gen 3D V- Cache, alternatively, peaked at 2TB/s (amongst plenty of different new info). We even have new footage and diagrams of the brand new 6nm I/O Die that AMD is utilizing for its Ryzen 7000 processors.

AMD has moved on to the second technology of 3D V-Cache and Intel has no competing expertise. This offers AMD a win in each the most effective CPUs for video games and sure datacenter purposes. Total, AMD’s second-generation 3D V-Cache expertise is a formidable step ahead over the first-gen, because it permits the corporate to make use of its now mature and cheaper 7nm course of node to spice up cutting-edge 5nm computing efficiency. to die. The brand new design represents AMD’s take into the third dimension the important thing benefit of chip-based design methodologies that use an older, cheaper compute node along side costly new compute expertise. Now for the finer particulars.

First, a fast high-level refresher. As you possibly can see above, AMD’s 3D V-Cache expertise locations an extra L3 SRAM chip straight within the middle of the computing die (CCD) to isolate it from heat-generating cores. This cache will increase the capability to 96MB for the 3D V-Cache geared up chip, bettering the efficiency of latency delicate purposes akin to gaming.

We acquired new details about the second technology implementation each straight from AMD and on the 2023 Worldwide Convention on Strong State Circuits (ISSCC), the place AMD gave a presentation on the Zen 4 structure.

AMD’s earlier technology 3D V-Cache used a 7nm L3 SRAM chip stacked on a 7nm Zen 3 CCD. AMD has caught to the 7nm course of for its new L3 SRAM chip, however is now putting it on prime of a smaller 5nm Zen 4 CCD (see chart under). Nonetheless, this creates a dimension mismatch that requires a number of adjustments.
