ZEN 3 AMD

On October 8, 2020, AMD will present new CPUs with Zen 3 technology, they will be marketed as Ryzen 4000. 

Also, AMD plans to unveil the RDNA2 architecture on October 28, 2020, and the graphics cards based on it will go on sale as the Radeon RX 6000.

As the teaser video shows, the Ryzen 4000 is again based internally on three chips on a carrier — one serves as an I/O die and integrates the DDR4 memory controller, the PCIe Gen4 interface, as well as SATA and USB. There are also two more, which contain the actual CPU cores, so the Ryzen 4000 may again have up to 16 cores.

The new Zen 3 CPU architecture uses various improvements, such as a CCX per CCD, for more performance per clock than before.

Zen 3 CPUs are to be manufactured in the 7nm + process by the Taiwanese company TSCM. Compared to Zen 2, the new chips are said to offer 20 percent more density and 10 percent less power consumption.

For RDNA2, AMD promises an increase in performance per watt of 50 percent compared to RDNA1. The current Radeon RX 5700 XT with Navi-10 chip requires 225 watts and, depending on the game — is as fast as a Geforce RTX 2070 or Geforce RTX 2070 Super. 

How fast a Navi-2X card with RDNA2 will remain to be seen for the time being — although AMD is flirting with the fact that Nvidia’s ampere models such as the Geforce RTX 3090/3080 are by no means unattainable. RDNA2 GPUs work in the new Microsoft Xbox Series X and S.
