AMD Ryzen 4000: everything you need to know about these powerful chips

Ryzen 3000 CPUs became a true milestone for AMD. But they are beginning to be something of the past, because the arrival of the next generation of processors, the AMD Ryzen 4000, is imminent, with launches divided between the beginning and the end of 2020.

As has happened with the latest versions of AMD, the 4000 series will be composed of mobile chips of current generation architecture and next-generation architecture desktop. So you don't get lost, here is everything we know about these processors.

Ryzen 4000: prices and release date

AMD Ryzen 4000. Roadmap of 7nm AMD processors

AMD presented the first Ryzen 4000 processors at the CES 2020 technology fair, where it showed a new generation of mobile APUs (accelerated processing units, for its acronym in English). These Zen 2 processor cores (found in Ryzen 3000 desktop processors) come alongside those of Vega graphics. In addition, a full range of processors were announced, from consumer electronics to high performance, which will begin to appear on laptops in the coming months of 2020 on the Lenovo Yoga Slim 7 and the Asus Zephyrus G14.

Ryzen 4000 desktop processors will probably arrive between July and October 2020. They will be built on the new Zen 3 architecture and will have several performance improvements. AMD has not yet announced any model or pricing information, but we expect a level similar to the current Ryzen 3000 series, whose prices range from $ 100 dollars to about $ 750 dollars for high-performance processors with multi-process capability.

The best processors focused on gamers They will probably be somewhere between $ 300 and $ 500.

Architecture

The Ryzen 4000 series processors, as well as the previous Ryzen 3000 generation, will use a combination of the two architectures throughout the range. The new Ryzen 4000 mobile processors and the Ryzen 3000 desktop take advantage of the existing Zen 2 architecture, albeit in a different way. The latter used a chiplet design, where the cores are distributed separately and combined with a larger input / output matrix, while the Ryzen 4000 Zen 2 use a more traditional monolithic design.

This should mean greater energy efficiency, since the input / output matrix is ??not present and requires its own power. However, the cache memory will be reduced and there is the possibility of additional memory latency, due to the decoupling of the infinite structure with the system memory. We will have to see some reference points and real additional tests before confirming it.

However, the Zen 2 architecture in Ryzen 4000 mobile processors will continue to be an important update on existing Ryzen 3000 mobile APUs based on the Zen + design. It decreases the process size from 12 nanometers (nm) to 7 nm and has a series of improvements in architectural efficiency. If Zen 2 desktop chips have something to do with it, it should mean that the first laptops with Ryzen 4000 will have about 15 percent higher clock instructions and will increase base and clock frequencies by several hundred MHz.

Ryzen 4000 desktop chips will be based on a new generation architecture called Zen 3. Don't be so drastic, but bring some notable improvements. It is based on the 7 nm + process of TSMC and is carried out using the new extreme ultraviolet lithography process, which should improve chip efficiency, in addition to reducing production costs. The latest rumors suggest that Zen 3 deliver 20 percent more transistor density than Zen 2, and reduce power requirements by 10 percent.

In October, WCCFTech reported that Zen 3 improvements will include lower cache latency and higher manufacturing speeds. That will help increase the CPI (instructions per cycle, by its acronym in English), by 8 percent over Zen 2 and deliver an additional 200MHz per core.

Ryzen 4000 mobile processors should see a significant improvement in performance over their Ryzen 3000 counterparts. The change from AMD to the 7 nm Zen 2 architecture offers intergenerational improvements of between 15 and 20 percent for single-threaded and 25 to 25 threading tasks. 30 percent in multi-threaded scenarios. That was most noticeable in the games, where the increase in cache helped generate elevations of 20 to 30 percent in frames per second and great improvements to lower frame rates of 1 and 0.1 percent. That meant a much higher consistency and frame rate stability.

AMD Ryzen 3 3250U 2/4 2.6GHz Up to 3.5GHz 3 Radeon Cores 15W

This is probably also the case with Ryzen 4000 Zen 2 chips, aided by traditionally strong integrated AMD graphics. Vega's graphic architecture may be few years old, but improvements in the 7nm process have increased its power by almost 60 percent compared to the last generation counterparts. Together, they should make the laptops for basic games with Ryzen 4000 APUs excellent. They will compete against Intel's new Ice Lake and the next Tiger Lake mobile processors, with their impressive integrated graphics.

Zen 3 improvements in Ryzen 4000 desktop processors will not be so dramatic. With the architectural advances, we expect an increase of approximately 10 percent in performance compared to Ryzen 3000 desktop chips, perhaps up to 15 percent in some cases. However, the rise in CPI is remarkable. Since that applies to both the configuration of one and multiple threads, it should close the gap with Intel in the games. Although Ryzen 4000 will have to compete with the 14th generation Comet Lake processors, it should do so favorably and may be a line more capable of gaming chips.

Zcalo AM4

One of the best features of AMD Ryzen processors has been the intergenerational support of the same AM4 socket. That means that those who bought first-generation Ryzen processors and main cards have been able to update their processors without the need to buy a new main card, they just need to update the BIOS. That will also be the case with Zen 3 Ryzen 4000 processors, although this will be the last generation of Ryzen chips to use the AM4 socket. The Ryzen 5000 processor, which probably arrives in 2021, goes from AM4 to a new socket design.
