Six months after the release of the third-generation AMD Ryzen processors, information leaks about the characteristics of future fourth-generation Ryzen chips, based on the next iteration of the Zen architecture at number 3, are gradually starting to leak out.
Zen 3 is expected to bring quite a few architectural improvements and optimizations. Several reputable sources claim that 4th Gen Ryzen chips will boast a 50% increase in floating-point and 17% improvement over 3rd Gen Ryzen CPUs in terms of instructions executed per clock cycle.
Also, the architecture of Zen 3 will significantly change the structure of the processor’s cache memory. At the moment, in Zen 2, one CCD (8-core chiplet) consists of two CCX (4-core clusters), each with 16MB of L3 cache, which gives us 32MB per CCD. According to the information we know, in Zen 3, all L3 cache will be available to both CCXs without any restrictions. Moreover, the volume of the third-level cache can increase significantly.
In addition to this information, several sources claim that AMD will be able to increase the clock speeds of the new generation of Ryzen processors by 200-300 MHz, which, as a result, should bring the chips on the Zen 3 architecture closer to the top 10-generation Core i9 processors in frequencies, with their rather impressive 5100MHz at all 10 cores.
It is worth noting one very important detail here: 10th generation Core chips will not show an increase in IPC (instructions per clock) compared to 9th generation Core processors, and for Ryzen 4000 an increase of 10 to 17% is indicated, which in combination with increased frequencies looks just amazing and in the end, may not leave a chance for the new 10th generation Intel processors.
Finally, the Ryzen 4000 processors will be the last chips released for the long-running AM4 platform with support for DDR4 memory. The next 5,000th generation of Ryzen processors will support the new DDR5 memory standard and will require a new socket (Socket AM5?), Which means new motherboards.
