AMD will increase CPU performance by two steps next year


AMD celebrated this week that it is five years since the company launched the first Ryzen processors. In connection with this, Robert Hallock, director of technical marketing at AMD, was also able to tell something about the upcoming products of the company.

Updates most things

Since 2016, many of AMD’s CPU products are based on the AM4 board. It is now nearing the end of the life of this socket, which means that the next generation of AMD CPU architecture, called Zen4, will not be able to use this socket, but will instead use the socket called AM5.

According to Hallock, the first products with Zen4 and AM5 will arrive sometime in 2022. This includes support for next-generation technologies such as DDR5 (memory) and PCI Express 5 (I / O). At the same time, it is promised that current AM4-compatible cooling units can be used in conjunction with AM5.

Extended life of AM4

Before this, beginning in 2022, AMD will be bringing a major update to the current family of Ryzen 5000 series CPUs. New models in this family will be equipped with what is called AMD V-cache, something that the company revealed during the Computex 2021 exchange earlier this year.

As early as 2019, AMD introduced what are called chipsets, which means that different parts of the CPU are made in different silicon chips, which are then packaged together in one CPU.

With V-cache memory, where the V stands for vertical, so one or more chipsets consisting of very fast SRAM memory are placed directly above what AMD calls the core complexes – ie the chipsets with the CPU cores. In practice, this is about L3 cache, and three times as much as in current models.

This summer, AMD CEO Lisa Su said that the bandwidth between this memory and the CPU cores is more than 2 terabytes per second.

Promises significant performance improvement

This will provide a significant increase in performance for software where a lot of data is shuffled between the cores and memory nearby, including in advanced computer games, where AMD promises an increase in performance of an average of 15 percent.

This should be as big an increase as what the company would normally achieve with a new generation of architecture. But the next generation of architectures will only come later in 2022.

The previously mentioned Hallock also spoke briefly about new energy-saving algorithms that AMD will introduce in firmware for laptops at the beginning of 2022. Unlike current algorithms, these will take into account to a greater extent the task that the PC actually performs.

More energy-efficient, x86-based solutions will be needed for AMD in the future, as the company no longer competes not only with Intel, but also with suppliers of arm-based processors.
