AMD Ryzen 9 3900X Processor |
The AMD Ryzen 9 3900X is a 12-core/24-thread processor AMD is pricing at $549, about the same as the current Core i9-10900K street price. AMD Ryzen 9 3900X CPU cores are built on the same 7 nm silicon fabrication process as the AMD Ryzen 3000 “Zen 2” processor, but with several refinements to the microarchitecture. The biggest change with “Zen 3” has to be the company doing away with the 4-core CCX and unifying all cores of the CPU chiplet into a single 8-core CCX. Even within the CPU core, AMD Ryzen 9 3900X has worked to reduce latencies, improved branch-prediction, optimized the execution engine, fattened the front-end and load/store units, and deployed faster caches, which has a direct impact on IPC, or single-thread performance.
IPC is the single biggest contributor to gaming performance, and the 19% claimed IPC gain over “Zen 2” should mean AMD has taken the gaming crown since the “Zen 2” architecture wasn’t too far behind “Comet Lake” at gaming to begin with.
