![]() ![]() With a Memory clock of above 3600MHz, the FCLK and UCLK are halved and operate in the ratio of 1:2.FCLK here refers to the Infinity Fabric clock and the way the new structure is designed, the memory can work asynchronously of the memory controller which was not the case with the Zen and Zen+ architecture. In Zen 2 the FCLK, MCLK (Memory) and UCLK (Memory Controller) operate in the ratio of 1:1:1 till the memory frequency is 3600MHz. Unlike the previous generations of Ryzen, the Zen 2 significantly improves the DRAM scalability and compatibility. The I/O chip has a dedicated memory controller, Infinity Fabric and other I/O functions. There is major transition from the previous generation of Ryzen chips as the new Ryzen 3000 chips have multi-chip architecture in addition to the I/O die which is fabricated on 12/14nm node(s). According to their slide, the 12nm I/O die is still using the solder bump. The Ryzen 3000 generation chips are soldered but differently as AMD has transitioned from solder bumps to 7nm CCD using copper pillars. A single-op support is provided for 256-AVX instructions. AMD has doubled the Floating Point and Load/Store bandwidth from 128b to 256b which is quite beefy. Store queue has been increased to 48 from 44 entry and we have 2 loads and 1 store per cycle operation. One more AGU unit has been added making the count 3 with a total of 4 ALUs. It has 224 entry ROB upped from 192 with 7 issue per cycle upped form 6. The physical register file has been upped from 168 to 180 entry (rename space).

The L1 cache is 32K with the 8-way association and L2 cache is still 512K with the 8-way association. In addition to more IPC (Instructions per Core), the new Cores in Zen 2 have improved branch predictor based on TAGE and revised L1 cache structure. The new Zen 2 microarchitecture is based on the 7nm fabrication process. By the way, you will be needing Motherboard For Ryzen 5 3600, but for that, we already have a guide, so check that as well. And today we are going to write on AMD RyReview. There are multiple advancements in Zen 2 over the predecessor. With Zen 2, AMD has furthered the technological advancement and maturity of their highly popular Zen architecture for Ryzen series of CPUs. “More Cores, More Cache, More Tech” is a tagline when it comes to AMD’s next generation of microarchitecture Zen2 which is based on their altogether new microarchitecture called Zen when launched in 2016 and followed by Zen+. ![]()
