AmD has released a new Zen 3 CPU architecture and a new Ryzen 5000 series desktop processor. At the launch, AMD also revealed the details of Zen 4. According to officials, the Zen 4-based architecture CPU will be available by 2022, while the new architecture will be upgraded to a 5nm process.
In today’s Zen 3 architecture, it continues to work with TSMC’s 7nm process, but in order to achieve further performance improvements, AMD has doubled the number of cores per CCX module to 8 (16 threads), doubled the three-stage cache capacity to 32MB, and all eight core shares are directly accessible, equivalent to doubling the three-level cache capacity of each core, greatly accelerating the communication between the core and cache memory in the actual application, and significantly reducing the latency of memory.
At the same time, each CCD small chip is still 8 core, and the internal contains CCX modules from two to one, CCX, CCD is basically the same meaning.
AMD claims that with the same 4GHz fixed frequency, 8 core configuration, combined with 25 application load test results, the IPC of the Zen 3 architecture is at least 19% higher than that of Zen 2!
